Technical: A Brief History of Payment Channels: from Satoshi to Lightning Network
Who cares about political tweets from some random country's president when payment channels are a much more interesting and are actually capable of carrying value? So let's have a short history of various payment channel techs!
Generation 0: Satoshi's Broken nSequence Channels
Because Satoshi's Vision included payment channels, except his implementation sucked so hard we had to go fix it and added RBF as a by-product. Originally, the plan for nSequence was that mempools would replace any transaction spending certain inputs with another transaction spending the same inputs, but only if the nSequence field of the replacement was larger. Since 0xFFFFFFFF was the highest value that nSequence could get, this would mark a transaction as "final" and not replaceable on the mempool anymore. In fact, this "nSequence channel" I will describe is the reason why we have this weird rule about nLockTime and nSequence. nLockTime actually only works if nSequence is not 0xFFFFFFFF i.e. final. If nSequence is 0xFFFFFFFF then nLockTime is ignored, because this if the "final" version of the transaction. So what you'd do would be something like this:
You go to a bar and promise the bartender to pay by the time the bar closes. Because this is the Bitcoin universe, time is measured in blockheight, so the closing time of the bar is indicated as some future blockheight.
For your first drink, you'd make a transaction paying to the bartender for that drink, paying from some coins you have. The transaction has an nLockTime equal to the closing time of the bar, and a starting nSequence of 0. You hand over the transaction and the bartender hands you your drink.
For your succeeding drink, you'd remake the same transaction, adding the payment for that drink to the transaction output that goes to the bartender (so that output keeps getting larger, by the amount of payment), and having an nSequence that is one higher than the previous one.
Eventually you have to stop drinking. It comes down to one of two possibilities:
You drink until the bar closes. Since it is now the nLockTime indicated in the transaction, the bartender is able to broadcast the latest transaction and tells the bouncers to kick you out of the bar.
You wisely consider the state of your liver. So you re-sign the last transaction with a "final" nSequence of 0xFFFFFFFF i.e. the maximum possible value it can have. This allows the bartender to get his or her funds immediately (nLockTime is ignored if nSequence is 0xFFFFFFFF), so he or she tells the bouncers to let you out of the bar.
Now that of course is a payment channel. Individual payments (purchases of alcohol, so I guess buying coffee is not in scope for payment channels). Closing is done by creating a "final" transaction that is the sum of the individual payments. Sure there's no routing and channels are unidirectional and channels have a maximum lifetime but give Satoshi a break, he was also busy inventing Bitcoin at the time. Now if you noticed I called this kind of payment channel "broken". This is because the mempool rules are not consensus rules, and cannot be validated (nothing about the mempool can be validated onchain: I sigh every time somebody proposes "let's make block size dependent on mempool size", mempool state cannot be validated by onchain data). Fullnodes can't see all of the transactions you signed, and then validate that the final one with the maximum nSequence is the one that actually is used onchain. So you can do the below:
Become friends with Jihan Wu, because he owns >51% of the mining hashrate (he totally reorged Bitcoin to reverse the Binance hack right?).
Slip Jihan Wu some of the more interesting drinks you're ordering as an incentive to cooperate with you. So say you end up ordering 100 drinks, you split it with Jihan Wu and give him 50 of the drinks.
When the bar closes, Jihan Wu quickly calls his mining rig and tells them to mine the version of your transaction with nSequence 0. You know, that first one where you pay for only one drink.
Because fullnodes cannot validate nSequence, they'll accept even the nSequence=0 version and confirm it, immutably adding you paying for a single alcoholic drink to the blockchain.
The bartender, pissed at being cheated, takes out a shotgun from under the bar and shoots at you and Jihan Wu.
Jihan Wu uses his mystical chi powers (actually the combined exhaust from all of his mining rigs) to slow down the shotgun pellets, making them hit you as softly as petals drifting in the wind.
The bartender mutters some words, clothes ripping apart as he or she (hard to believe it could be a she but hey) turns into a bear, ready to maul you for cheating him or her of the payment for all the 100 drinks you ordered from him or her.
Steely-eyed, you stand in front of the bartender-turned-bear, daring him to touch you. You've watched Revenant, you know Leonardo di Caprio could survive a bear mauling, and if some posh actor can survive that, you know you can too. You make a pose. "Drunken troll logic attack!"
I think I got sidetracked here.
Bears are bad news.
You can't reasonably invoke "Satoshi's Vision" and simultaneously reject the Lightning Network because it's not onchain. Satoshi's Vision included a half-assed implementation of payment channels with nSequence, where the onchain transaction represented multiple logical payments, exactly what modern offchain techniques do (except modern offchain techniques actually work). nSequence (the field, but not its modern meaning) has been in Bitcoin since BitCoin For Windows Alpha 0.1.0. And its original intent was payment channels. You can't get nearer to Satoshi's Vision than being a field that Satoshi personally added to transactions on the very first public release of the BitCoin software, like srsly.
Miners can totally bypass mempool rules. In fact, the reason why nSequence has been repurposed to indicate "optional" replace-by-fee is because miners are already incentivized by the nSequence system to always follow replace-by-fee anyway. I mean, what do you think those drinks you passed to Jihan Wu are, other than the fee you pay him to mine a specific version of your transaction?
Satoshi made mistakes. The original design for nSequence is one of them. Today, we no longer use nSequence in this way. So diverging from Satoshi's original design is part and parcel of Bitcoin development, because over time, we learn new lessons that Satoshi never knew about. Satoshi was an important landmark in this technology. He will not be the last, or most important, that we will remember in the future: he will only be the first.
Incentive-compatible time-limited unidirectional channel; or, Satoshi's Vision, Fixed (if transaction malleability hadn't been a problem, that is). Now, we know the bartender will turn into a bear and maul you if you try to cheat the payment channel, and now that we've revealed you're good friends with Jihan Wu, the bartender will no longer accept a payment channel scheme that lets one you cooperate with a miner to cheat the bartender. Fortunately, Jeremy Spilman proposed a better way that would not let you cheat the bartender. First, you and the bartender perform this ritual:
You get some funds and create a transaction that pays to a 2-of-2 multisig between you and the bartender. You don't broadcast this yet: you just sign it and get its txid.
You create another transaction that spends the above transaction. This transaction (the "backoff") has an nLockTime equal to the closing time of the bar, plus one block. You sign it and give this backoff transaction (but not the above transaction) to the bartender.
The bartender signs the backoff and gives it back to you. It is now valid since it's spending a 2-of-2 of you and the bartender, and both of you have signed the backoff transaction.
Now you broadcast the first transaction onchain. You and the bartender wait for it to be deeply confirmed, then you can start ordering.
The above is probably vaguely familiar to LN users. It's the funding process of payment channels! The first transaction, the one that pays to a 2-of-2 multisig, is the funding transaction that backs the payment channel funds. So now you start ordering in this way:
For your first drink, you create a transaction spending the funding transaction output and sending the price of the drink to the bartender, with the rest returning to you.
You sign the transaction and pass it to the bartender, who serves your first drink.
For your succeeding drinks, you recreate the same transaction, adding the price of the new drink to the sum that goes to the bartender and reducing the money returned to you. You sign the transaction and give it to the bartender, who serves you your next drink.
At the end:
If the bar closing time is reached, the bartender signs the latest transaction, completing the needed 2-of-2 signatures and broadcasting this to the Bitcoin network. Since the backoff transaction is the closing time + 1, it can't get used at closing time.
If you decide you want to leave early because your liver is crying, you just tell the bartender to go ahead and close the channel (which the bartender can do at any time by just signing and broadcasting the latest transaction: the bartender won't do that because he or she is hoping you'll stay and drink more).
If you ended up just hanging around the bar and never ordering, then at closing time + 1 you broadcast the backoff transaction and get your funds back in full.
Now, even if you pass 50 drinks to Jihan Wu, you can't give him the first transaction (the one which pays for only one drink) and ask him to mine it: it's spending a 2-of-2 and the copy you have only contains your own signature. You need the bartender's signature to make it valid, but he or she sure as hell isn't going to cooperate in something that would lose him or her money, so a signature from the bartender validating old state where he or she gets paid less isn't going to happen. So, problem solved, right? Right? Okay, let's try it. So you get your funds, put them in a funding tx, get the backoff tx, confirm the funding tx... Once the funding transaction confirms deeply, the bartender laughs uproariously. He or she summons the bouncers, who surround you menacingly. "I'm refusing service to you," the bartender says. "Fine," you say. "I was leaving anyway;" You smirk. "I'll get back my money with the backoff transaction, and posting about your poor service on reddit so you get negative karma, so there!" "Not so fast," the bartender says. His or her voice chills your bones. It looks like your exploitation of the Satoshi nSequence payment channel is still fresh in his or her mind. "Look at the txid of the funding transaction that got confirmed." "What about it?" you ask nonchalantly, as you flip open your desktop computer and open a reputable blockchain explorer. What you see shocks you. "What the --- the txid is different! You--- you changed my signature?? But how? I put the only copy of my private key in a sealed envelope in a cast-iron box inside a safe buried in the Gobi desert protected by a clan of nomads who have dedicated their lives and their childrens' lives to keeping my private key safe in perpetuity!" "Didn't you know?" the bartender asks. "The components of the signature are just very large numbers. The sign of one of the signature components can be changed, from positive to negative, or negative to positive, and the signature will remain valid. Anyone can do that, even if they don't know the private key. But because Bitcoin includes the signatures in the transaction when it's generating the txid, this little change also changes the txid." He or she chuckles. "They say they'll fix it by separating the signatures from the transaction body. They're saying that these kinds of signature malleability won't affect transaction ids anymore after they do this, but I bet I can get my good friend Jihan Wu to delay this 'SepSig' plan for a good while yet. Friendly guy, this Jihan Wu, it turns out all I had to do was slip him 51 drinks and he was willing to mine a tx with the signature signs flipped." His or her grin widens. "I'm afraid your backoff transaction won't work anymore, since it spends a txid that is not existent and will never be confirmed. So here's the deal. You pay me 99% of the funds in the funding transaction, in exchange for me signing the transaction that spends with the txid that you see onchain. Refuse, and you lose 100% of the funds and every other HODLer, including me, benefits from the reduction in coin supply. Accept, and you get to keep 1%. I lose nothing if you refuse, so I won't care if you do, but consider the difference of getting zilch vs. getting 1% of your funds." His or her eyes glow. "GENUFLECT RIGHT NOW." Lesson learned?
Payback's a bitch.
Transaction malleability is a bitchier bitch. It's why we needed to fix the bug in SegWit. Sure, MtGox claimed they were attacked this way because someone kept messing with their transaction signatures and thus they lost track of where their funds went, but really, the bigger impetus for fixing transaction malleability was to support payment channels.
Yes, including the signatures in the hash that ultimately defines the txid was a mistake. Satoshi made a lot of those. So we're just reiterating the lesson "Satoshi was not an infinite being of infinite wisdom" here. Satoshi just gets a pass because of how awesome Bitcoin is.
CLTV-protected Spilman Channels
Using CLTV for the backoff branch. This variation is simply Spilman channels, but with the backoff transaction replaced with a backoff branch in the SCRIPT you pay to. It only became possible after OP_CHECKLOCKTIMEVERIFY (CLTV) was enabled in 2015. Now as we saw in the Spilman Channels discussion, transaction malleability means that any pre-signed offchain transaction can easily be invalidated by flipping the sign of the signature of the funding transaction while the funding transaction is not yet confirmed. This can be avoided by simply putting any special requirements into an explicit branch of the Bitcoin SCRIPT. Now, the backoff branch is supposed to create a maximum lifetime for the payment channel, and prior to the introduction of OP_CHECKLOCKTIMEVERIFY this could only be done by having a pre-signed nLockTime transaction. With CLTV, however, we can now make the branches explicit in the SCRIPT that the funding transaction pays to. Instead of paying to a 2-of-2 in order to set up the funding transaction, you pay to a SCRIPT which is basically "2-of-2, OR this singlesig after a specified lock time". With this, there is no backoff transaction that is pre-signed and which refers to a specific txid. Instead, you can create the backoff transaction later, using whatever txid the funding transaction ends up being confirmed under. Since the funding transaction is immutable once confirmed, it is no longer possible to change the txid afterwards.
Todd Micropayment Networks
The old hub-spoke model (that isn't how LN today actually works). One of the more direct predecessors of the Lightning Network was the hub-spoke model discussed by Peter Todd. In this model, instead of payers directly having channels to payees, payers and payees connect to a central hub server. This allows any payer to pay any payee, using the same channel for every payee on the hub. Similarly, this allows any payee to receive from any payer, using the same channel. Remember from the above Spilman example? When you open a channel to the bartender, you have to wait around for the funding tx to confirm. This will take an hour at best. Now consider that you have to make channels for everyone you want to pay to. That's not very scalable. So the Todd hub-spoke model has a central "clearing house" that transport money from payers to payees. The "Moonbeam" project takes this model. Of course, this reveals to the hub who the payer and payee are, and thus the hub can potentially censor transactions. Generally, though, it was considered that a hub would more efficiently censor by just not maintaining a channel with the payer or payee that it wants to censor (since the money it owned in the channel would just be locked uselessly if the hub won't process payments to/from the censored user). In any case, the ability of the central hub to monitor payments means that it can surveill the payer and payee, and then sell this private transactional data to third parties. This loss of privacy would be intolerable today. Peter Todd also proposed that there might be multiple hubs that could transport funds to each other on behalf of their users, providing somewhat better privacy. Another point of note is that at the time such networks were proposed, only unidirectional (Spilman) channels were available. Thus, while one could be a payer, or payee, you would have to use separate channels for your income versus for your spending. Worse, if you wanted to transfer money from your income channel to your spending channel, you had to close both and reshuffle the money between them, both onchain activities.
Poon-Dryja Lightning Network
Bidirectional two-participant channels. The Poon-Dryja channel mechanism has two important properties:
No time limit.
Both the original Satoshi and the two Spilman variants are unidirectional: there is a payer and a payee, and if the payee wants to do a refund, or wants to pay for a different service or product the payer is providing, then they can't use the same unidirectional channel. The Poon-Dryjam mechanism allows channels, however, to be bidirectional instead: you are not a payer or a payee on the channel, you can receive or send at any time as long as both you and the channel counterparty are online. Further, unlike either of the Spilman variants, there is no time limit for the lifetime of a channel. Instead, you can keep the channel open for as long as you want. Both properties, together, form a very powerful scaling property that I believe most people have not appreciated. With unidirectional channels, as mentioned before, if you both earn and spend over the same network of payment channels, you would have separate channels for earning and spending. You would then need to perform onchain operations to "reverse" the directions of your channels periodically. Secondly, since Spilman channels have a fixed lifetime, even if you never used either channel, you would have to periodically "refresh" it by closing it and reopening. With bidirectional, indefinite-lifetime channels, you may instead open some channels when you first begin managing your own money, then close them only after your lawyers have executed your last will and testament on how the money in your channels get divided up to your heirs: that's just two onchain transactions in your entire lifetime. That is the potentially very powerful scaling property that bidirectional, indefinite-lifetime channels allow. I won't discuss the transaction structure needed for Poon-Dryja bidirectional channels --- it's complicated and you can easily get explanations with cute graphics elsewhere. There is a weakness of Poon-Dryja that people tend to gloss over (because it was fixed very well by RustyReddit):
You have to store all the revocation keys of a channel. This implies you are storing 1 revocation key for every channel update, so if you perform millions of updates over your entire lifetime, you'd be storing several megabytes of keys, for only a single channel. RustyReddit fixed this by requiring that the revocation keys be generated from a "Seed" revocation key, and every key is just the application of SHA256 on that key, repeatedly. For example, suppose I tell you that my first revocation key is SHA256(SHA256(seed)). You can store that in O(1) space. Then for the next revocation, I tell you SHA256(seed). From SHA256(key), you yourself can compute SHA256(SHA256(seed)) (i.e. the previous revocation key). So you can remember just the most recent revocation key, and from there you'd be able to compute every previous revocation key. When you start a channel, you perform SHA256 on your seed for several million times, then use the result as the first revocation key, removing one layer of SHA256 for every revocation key you need to generate. RustyReddit not only came up with this, but also suggested an efficient O(log n) storage structure, the shachain, so that you can quickly look up any revocation key in the past in case of a breach. People no longer really talk about this O(n) revocation storage problem anymore because it was solved very very well by this mechanism.
Another thing I want to emphasize is that while the Lightning Network paper and many of the earlier presentations developed from the old Peter Todd hub-and-spoke model, the modern Lightning Network takes the logical conclusion of removing a strict separation between "hubs" and "spokes". Any node on the Lightning Network can very well work as a hub for any other node. Thus, while you might operate as "mostly a payer", "mostly a forwarding node", "mostly a payee", you still end up being at least partially a forwarding node ("hub") on the network, at least part of the time. This greatly reduces the problems of privacy inherent in having only a few hub nodes: forwarding nodes cannot get significantly useful data from the payments passing through them, because the distance between the payer and the payee can be so large that it would be likely that the ultimate payer and the ultimate payee could be anyone on the Lightning Network. Lessons learned?
We can decentralize if we try hard enough!
"Hubs bad" can be made "hubs good" if everybody is a hub.
Smart people can solve problems. It's kinda why they're smart.
After LN, there's also the Decker-Wattenhofer Duplex Micropayment Channels (DMC). This post is long enough as-is, LOL. But for now, it uses a novel "decrementing nSequence channel", using the new relative-timelock semantics of nSequence (not the broken one originally by Satoshi). It actually uses multiple such "decrementing nSequence" constructs, terminating in a pair of Spilman channels, one in both directions (thus "duplex"). Maybe I'll discuss it some other time. The realization that channel constructions could actually hold more channel constructions inside them (the way the Decker-Wattenhofer puts a pair of Spilman channels inside a series of "decrementing nSequence channels") lead to the further thought behind Burchert-Decker-Wattenhofer channel factories. Basically, you could host multiple two-participant channel constructs inside a larger multiparticipant "channel" construct (i.e. host multiple channels inside a factory). Further, we have the Decker-Russell-Osuntokun or "eltoo" construction. I'd argue that this is "nSequence done right". I'll write more about this later, because this post is long enough. Lessons learned?
Bitcoin offchain scaling is more powerful than you ever thought.
Slack log for Ark token's value proposition discussion 16-07-18
Please find below a log of the discussion we had in slack regarding the ark token's value proposition. Some of the community members who happen to be long term holders of ark feel that the ark token's value proposition isn't clearly communicated by the team so they asked about it. I'm posting the entire discussion it here to make a permanent record since slack wipes messages after a while. -------------------------------------------------------------------------------------------- arigard [7:21 PM] Hey team, so I'm curious. Is there any update on a new white paper at all that was being mentioned? I've been holding Ark since it hit Bittrex and I personally don't really have a clear idea about how the token is going to work in the overall picture, or what really the direction is for the project once v2 is out. It feels like things have gone a bit flat recently, are there any updates on direction and what the plan is once V2 is live? Is there any idea about when it might go live? Or how the Ark token will fit into the economy (will it be a gas?). I see a lot of other projects i'm invested in coming up with very clear roadmaps/dates and direction about what they want to be and I still personally feel Ark's message is a little confused and hard to read especially for people who are not coders/developers. rob [ Ark Labs ] [7:22 PM] the roadmap is on the site, arkdirectory.com/kits has nice presentations and other goodies roks0n (deadlock) [7:23 PM] @Matthew_DC mentioned a couple of days ago that he’s preparing several blog posts which should explain most of these @arigard rob [ Ark Labs ] [7:23 PM] the Blog also goes into lots of v2 details Djenny Floro (Ark Tribe) [7:24 PM] Hi everyone. rob [ Ark Labs ] [7:24 PM] Ark is Ark, not like Eth with gas, hence no gas. Hey @Djenny Floro (Ark Tribe) welcome back Djenny Floro (Ark Tribe) [7:24 PM] Hey rob, hi Rok :slightly_smiling_face: roks0n (deadlock) [7:25 PM] Rob, I think he means how everything will be connected with ArkVM etc. similar conversation as the one few days ago (edited) Djenny Floro (Ark Tribe) [7:25 PM] It's been a while, but I was head on in the project, sorry for not showing more often. arigard [7:25 PM] Yeah my main question is really I still don't know what will give the actual Ark token value . goldenpepe [7:25 PM] we dont know how the arkvm will work All we can do is wait Doubled1c3 (ArkStickers.com) [7:26 PM] uploaded and commented on this image: bucket.jpg @Djenny Floro (Ark Tribe) goldenpepe [7:26 PM] We can make assumptions but that's all they'll be roks0n (deadlock) [7:26 PM] @arigard this was the discussion: https://arkecosystem.slack.com/archives/C2ABRLZB8/p1531422791000216 roks0n (deadlock) definitely, I’m not blaming anyone :slightly_smiling_face: Was just curious if there were any developments in terms of the updated whitepaper because I was reading one of the threads on reddit from 6 months ago where it was mentioned you’re looking to hire someone write it up. Posted in #generalJul 12th arigard [7:26 PM] And I kind of feel this is such a big elephant in the room for people in the long run. roks0n (deadlock) [7:26 PM] click on the link and read from that post on (edited) arigard [7:26 PM] ok Djenny Floro (Ark Tribe) [7:27 PM] I saw that there has been some drawbacks with the V2 ? (Not sure if it's exact, I only came a few times and seemed to understand it was so) goldenpepe [7:28 PM] There are just some incompatibilities between v1 and v2 in devnet which is why devnet is currently down rob [ Ark Labs ] [7:28 PM] ArkVM may be unnecessary as more modern approaches to handling contracts are available, one of the main issue is having them be distributed just like the tokens. goldenpepe [7:28 PM] There's a community run v2-only devnet though #devnet_unofficial rob [ Ark Labs ] [7:28 PM] it's more like drawback with v1 arigard [7:30 PM] I mean I've seen a lot of stuff in that discussion discussed over the past year and there still seems to be no concrete answers coming out and that is a bit of worry to me personally. It makes it look like the team doesn't even know. I think most that know of Ark understand it wants to create an easy way to deploy blockchains and work as a platform and have some inoperability options. But the fundamentals of how that work right now seems to be up in the air. In other projects I know what gives those tokens value, but in Ark I don't, so it's hard for me as an investor to really sell to someone else the benefits of the token when there is a big question mark still on it. rob [ Ark Labs ] [7:33 PM] do you know that Ark Deployer has been available for quite some time? arigard [7:34 PM] Yes, that doesn't really answer any questions though. mak [7:34 PM] Ark deployer helps the main chain's business case somehow? arigard [7:35 PM] What gives Ark token actual value? Like what is the reason people need to buy and hold the Ark token? That is my question. Djenny Floro (Ark Tribe) [7:36 PM] @mak what you're saying is kinda like answering you can use a hammer when asked what a nail do. arigard [7:36 PM] You don't need to buy the Ark token to deploy a chain. You can just do it. Djenny Floro (Ark Tribe) [7:36 PM] I mean, the Ark Deployer doesn't answer what's the Ark. mak [7:36 PM] @Djenny Floro (Ark Tribe) my point was directed towards rob's comment. I think you misunderstood it. Djenny Floro (Ark Tribe) [7:37 PM] @mak My bad then. I apologize. Blockhunter [7:38 PM] :boogieark9: rob [ Ark Labs ] [7:38 PM] " I think most that know of Ark understand it wants to create an easy way to deploy blockchains and work as a platform and have some inoperability options. But the fundamentals of how that work right now seems to be up in the air." This is why I wrote that.. there is no mystery of how that works. You are mistaken or uninformed. arkenstone [7:38 PM] That's the problem here because team is programming orientated but there hasn't been alot done on business aspect of the token and marketing investor point big view mak [7:38 PM] That only explains the value of the ark codebase not the blockchain though arigard [7:38 PM] I think you seem to be trying to turn the argument in a seperate direction. It's a simple question. What gives the Ark token value. rob [ Ark Labs ] [7:39 PM] The market does. It's on 19 different exchanges. arigard [7:39 PM] Seems like you are being unhelpfully obtuse. I'll rephrase. roks0n (deadlock) [7:39 PM] so one thing that is clear to me is interoperability using ACES, where ARK is used as a “middleman” between two different chains, so if there’s high volume between those chains, it means the volume of ark increases as well .. what I’d like to know is how things will work with arkvm and how it will all work with sidechains (on eth, all the side chains will basically link back to the main chain which will be the one responsible for security afaik?) arigard [7:39 PM] What gives the Ark token value in the Ark ecosystem. Blockhunter [7:40 PM] Vote for Pedro he will make all your dreams come true arigard [7:40 PM] Eth is a gas, Waves is a gas. Ark is... what? mak [7:40 PM] ACES can work with any chains though. Doesn't have to be ark main chain. So I guess tomorrow persona can become the settlement layer for the Ark ecosystem and there's no incentive to stop it from happening. arigard [7:40 PM] ^ roks0n (deadlock) [7:41 PM] Mak, correct but if there are already lots of chains connected between ARK, it will be more appealing to link it through ARK directly Djenny Floro (Ark Tribe) [7:41 PM] As I understand it, ACES could be using any given blockchain as the middle man... roks0n (deadlock) [7:41 PM] it doesn’t mean that it can’t be copied tho arigard [7:41 PM] But there are no chains connected through Ark atm That have any real value anyway roks0n (deadlock) [7:41 PM] eth and btc are arigard [7:41 PM] And they can be connected through any Ark clone. bangomatic [7:41 PM] I'd love to hear the Ark team chime in on this discussion arigard [7:42 PM] So anyone can come along and make another chain that can instantly overtake Ark at this present time if there isn't a failsafe reason for Ark to be the defacto currency. rob [ Ark Labs ] [7:42 PM] https://arkecosystem.slack.com/archives/C2ABRLZB8/p1531762883000422 you can't keep saying things like this as if they are true. arigard That have any real value anyway Posted in #generalToday at 7:41 PM Blockhunter [7:42 PM] Interoperability to the moon mak [7:42 PM] "it will be more appealing to link it through ARK directly" Currently Ark is the only mature chain because it's been around longer but the moment persona or some other bridge chain gets listed on an exchange that dynamic is no longer there. So why would you prefer Ark over persona when that happens. That's the question as far as I understand it. (edited) rob [ Ark Labs ] [7:43 PM] Persona has other goals, not duplicating Ark goals Djenny Floro (Ark Tribe) [7:43 PM] @bangomatic Hi! arigard [7:43 PM] What current sidechain of Ark has real value/position in the crypto market? Persona? bangomatic [7:43 PM] hey @Djenny Floro (Ark Tribe)! mak [7:43 PM] The blockchain as a transaction medium doesn't care about secondary goals. It still has all the capabilities that Ark has. Colby [7:43 PM] What has value right now? :thinking_face: rob [ Ark Labs ] https://arkecosystem.slack.com/archives/C2ABRLZB8/p1531762883000422 you can't keep saying things like this as if they are true. https://arkecosystem.slack.com/archives/C2ABRLZB8/p1531762883000422 Posted in #generalToday at 7:42 PM arigard [7:43 PM] Ark's ecosystem at present is not big enough to be a reason not to just take the tech and start your own. To think otherwise is ludicrous. rob [ Ark Labs ] [7:44 PM] that's a fine opinion Jarunik [7:44 PM] it is harder than you think :slightly_smiling_face: arigard [7:44 PM] We aren't Eth with multi $100mn + start ups and even if we were, what's currently to stop one of those just overtaking Ark and leaving it behind? Jarunik [7:45 PM] i hope some ark clones get really sucessful to be honest :slightly_smiling_face: Colby [7:45 PM] Same here! Jarunik i hope some ark clones get really sucessful to be honest :slightly_smiling_face: Posted in #generalToday at 7:45 PM Blockhunter [7:45 PM] HODL ROCKET TECHNOLOGY mak [7:45 PM] Same here but then there's no reason to hold Ark over something else arigard [7:45 PM] i hope so too if there is some reason for Ark to always be there at the top considering it's the Ark platform. Colby [7:45 PM] But the thing is that I am wondering, if ark clones get successful, what benefits does it give back to ark Djenny Floro (Ark Tribe) [7:45 PM] @Jarunik to create an ecosystem? mak [7:45 PM] Right now we have to consider Ark's value not the other bridge chains arigard [7:45 PM] But if there isn't a reason for Ark to exist at the top, why are we all holding it? Colby [7:45 PM] Haha I think we are all thinking the same :slightly_smiling_face: arigard [7:45 PM] It's a terrible business plan rob [ Ark Labs ] [7:46 PM] the point of BridgeChains is to allow new projects with no access the market a path to them through Ark, and hence gain value. Other blockchains connections are through ACES, such as BTC, LTC, ETH, and more coming.. Persona has a way to trade Ark <> Prs arigard [7:47 PM] What is to stop them from getting their own exchanges in the future and just using Ark as a stepping stone to becoming their own platform operator? mak [7:47 PM] Sure rob, but there's now 10 different projects doing the same and they are faster in development than the ark team is arigard [7:47 PM] ^ Blockhunter [7:47 PM] Ark is the Yoda of blockchain and they need a better catchphrase. Better than ark gives no dates or point click blockchain arigard [7:48 PM] This attitude seems horribly naive if this is the value proposition. mak [7:48 PM] All of us believe in the vision that Ark brought us but I personally am not sure if Ark is the best option to execute that vision in time arigard [7:48 PM] The issue is, we don't know what the value proposition is. mak [7:48 PM] Other projects seem much faster rob [ Ark Labs ] [7:48 PM] if you are into speculation, which it seems you are, then on paper all of your projects with no code are better and have more value than Ark arigard [7:48 PM] That's not true at all. lol. Matthew_DC [7:49 PM] At the most base level, ARK is a common currency token that is essentially automatically compatible with every bridge chain that is built based on ARK and is optimized for transaction volume and throughput to avoid bloat of other mechanisms introduced by the other chains. That is at the most basic level. By holding the ARK token itself, you will be able to enact the functions of multiple bridged chains both issued by our team and others. You will also be able to utilize the ARK chain as a pegged token to many bridged chains but that process will be transparent to users as it will be done behind the scenes without the user needing to do any functions. To think that someone will fork the code and generate a more effective ARK main chain means you have no confidence in the ARK team as the primary developer of the technology itself. In this case, if we are not and someone pushes a better version of the network, then I would argue maybe they SHOULD be chosen. That is the point of a free and open market. Not to mention the potential for registering and providing snapshot hashes to the main ARK blockchain to provide added security measures to a bridge chain with lower security due to lower market share etc, those are just baseline reasons. As I mentioned the other day, at face value, consider this. What brings value to Litecoin or Bitcoin or Doge? In essence, ARK is a more effective currency and base network than all of these aforementioned networks with all of the added benefits being added for additional use cases. roks0n (deadlock) [7:50 PM] will ark based chains be bridged via arkvm? goldenpepe [7:50 PM] They cant be You'd need the VM on both sides Matthew_DC [7:50 PM] I am currently on a conference call and have a lot going on so I can't respond too much. goldenpepe [7:50 PM] You can use AIP11's new tx types to do a sort of escrow between chains though i think mak [7:50 PM] @Matthew_DC Are you saying that the bridgechains deployed by ark-deployer don't have the same features? rob [ Ark Labs ] [7:50 PM] ArkVM is not for bridging chains goldenpepe [7:51 PM] It can be Coinme [7:51 PM] And ICO's that will join Ark in the future will use it for buying their token. goldenpepe [7:51 PM] But both chains will need to be running the VM Matthew_DC [7:51 PM] The ARK main chain will have specific methods of allowing token transfer and utilization between chains to include quasi-centralized methods through aces, decentralized aces based intermediary networks, Time locked transfers, among custom built smart contract like logic built into the core technology itself that doesn't make the network susceptible to the bloat and mis-utilization an vulnerabilities of full VM use. goldenpepe [7:51 PM] (which the main ark chain wont be) mak [7:51 PM] "ICO's that will join Ark in the future will use it for buying their token" Or any other bridgechain that's listed on exchanges @Matthew_DC So will all of the bridgechains, no? I could start an ACES node today for persona and it will have no difference from what you describe. Matthew_DC [7:52 PM] @mak no, we promised ARK would be open source and everything we build for the core ARK blockchain will be open source. arigard [7:53 PM] You can be open source and still protect your value.. Matthew_DC [7:54 PM] The point of ARK from day 1 has been to create a better base layer blockchain technology and protocol for everyone everywhere to be able to use to create anything they can dream up. The ARK token is a core payment layer for the ecosystem including any applications we build ourselves, sponsor, partner with, or support. mak [7:54 PM] It seems like the team's vision for Ark is as a software product only and there's no business plan for the main chain. Which is fine but it's not explained as such. (edited) Blockhunter [7:55 PM] Great to see such active discussions goldenpepe [7:55 PM] I think what Matt is trying to portray is this: A single universal Ark Ecosystem wallet holding ARK that has a nice UI with a list of dapps in the ecosystem You select a dapp You send a tx from the wallet using Ark ----------------Everything below this line is transparent to the user----------------- The Ark transaction has instructions in the smartbridge field The Ark gets converted to dappCoin via an intermediary like ACES (trustful) or a trustless escrow smart contract The intermediary received Ark and uses the dappCoin on the dapp chain to do whatever it is the user wanted to do using the instructions in the smartbridge field The dappchain responds to the request to the intermediary Intermediary sends an Ark tx with the results of the dapp computation/action in the smartbridge field ---------------Everything above this line is transparent to the user------------------- After 8+ seconds, user's wallet shows them the result of their interaction with the dapp bridgechain That's where the value of Ark will come from The Ark coin will be a universal "omni-coin" Matthew_DC [7:56 PM] :this: This goldenpepe [7:56 PM] That will instantly shapeshift into bridgechain coins to interact with the bridgechain dapp mak [7:58 PM] I understand what your point is and I agree it will work but only as long as none of the bridge chains are on an exchange when for example persona gets listed on binance the scenario changes and now either chain can become the backbone of the ark ecosystem arigard [7:58 PM] Yes. We see that. But hypothetically what is to stop a bridged Ark chain from becoming bigger than Ark and then going on to become that gateway? At this point it just seems to be hopium that the Ark network will always be the one people look to. But in one year, or two, or five, it might not be the case. What is to stop Ark being just sidelined if another team come along with develop on what Ark has built and propel it forward and take the mantle? goldenpepe [7:58 PM] What you say will be a problem only if the utility of the dapp coin is greater than the utility of the ark omnicoin Would you rather hold a coin that can do one thing and is forever tied to a single chain arigard [7:59 PM] But in other crypto's an app becoming sucessfull is a benefit. In Ark's network it could be a negative. goldenpepe [7:59 PM] Or would you rather hold a coin that can interact with that single chain and 3232523432 others arigard [7:59 PM] But why can't another coin become an omnicoin? If there are no limitations against it goldenpepe [7:59 PM] Why can't another coin become ethereum? mak [7:59 PM] "What you say will be a problem only if the utility of the dapp coin is greater than the utility of the ark omnicoin" Or if it gives out better staking returns etc like persona because of higher inflation rate goldenpepe [7:59 PM] if there are no limitations against it You can literally go on AWS right now and deploy an ethereum clone chain arigard [7:59 PM] It can, but an ETH token can't oust ETH That's the difference. We are giving people an easy route here. rob [ Ark Labs ] [7:59 PM] do you often think your children should not surpass you? Or is that the hope? Matthew_DC [8:00 PM] Well it's about security, trust, potential vulnerabilities due to added functionality, the ability of the bridgechain team to create interactions and focus on use cases for their token outside of their core use, etc. But that's the point of open and free markets goldenpepe [8:00 PM] There is a solution to your concern @arigard Matthew_DC [8:00 PM] What is to stop someone from being better than Bitcoin? arigard [8:01 PM] I think all these strawman arguments are fun, but they still aren't adressing the issuel goldenpepe [8:01 PM] Instead of having Ark Deployer literally cloning the ark codebase, have it be a turnkey solution to run a layer 2 chain Matthew_DC [8:01 PM] You could go fork Ethereum right now and have an exact copy of the capability of the main Eth chain. goldenpepe [8:01 PM] bridgechain dapps can be "colored coins" that are forever tied to the main chain arigard [8:01 PM] Yeah but you wouldn't have those businesses on the chain. goldenpepe [8:01 PM] but that would introduce bloat Matthew_DC [8:01 PM] So you are saying the utility of Ethereum is adoption. arigard [8:01 PM] And those businesses won't have the potential to become the main ETH. Matthew_DC [8:01 PM] Which is the case for the value of any token. goldenpepe [8:01 PM] @arigard It sounds like you want ark to become Ethereum Plasma arigard [8:02 PM] I just want an answer. Matthew_DC [8:02 PM] How many companies are pulling their ERC20 tokens off of Ethereum because of the issues? Colby [8:02 PM] Yeah but correct me if im wrong goldenpepe [8:02 PM] There is no answer that will satisfy what you are asking arigard [8:02 PM] And i keep getting strawmanned. Colby [8:02 PM] Ethereum projects NEED eth for gas Matthew_DC [8:02 PM] We talk to people almost every day that are looking to leave Ethereum. Colby [8:02 PM] Ark is needed for? arigard [8:02 PM] ^ Colby [8:02 PM] This is all I am wondering, where does the ark coin fit into it I love the idea goldenpepe [8:02 PM] @arigard You want ark-based coins to rely on Ark The team wants the Ark chain to not be bloated The solution to this is unironically ethereum plasma and sharding Colby [8:02 PM] but have been waiting for a while to know how the Ark coin will actually be used goldenpepe [8:03 PM] Shards in ethereum are basically "bridgechains" arigard [8:03 PM] Ok, and those teams might be big enough and clued up enough to eventually knock Ark from being the de facto omni coin. That's the worry. If this is in fact the possibility. Then it should be clear. mak [8:03 PM] "You could go fork Ethereum right now and have an exact copy of the capability of the main Eth chain." @Matthew_DC Ethereum has value because all the dapps live on it which is not true for ark arigard [8:03 PM] Because as an investor it worries me, a lot. I don't know where the value of Ark as an investment is 100% right now. Jarunik [8:03 PM] Ark is basically the inverse approach to Ethereum. Eth goes for big one-fits all first and tries to shard ... Ark is creating shards and then combines them goldenpepe [8:03 PM] There is no solution to what @arigard and @mak are saying right now Literally no existing solution Only proposals like sharding arigard [8:04 PM] And all this noise about defensiveness doesn't help. These are legit concerns. Matthew_DC [8:04 PM] When was it not clear that if a company comes along and builds a better more used product it could potentially take over market share? That's how all free markets work. You can't believe in open source and build and open source product without that risk. arigard [8:04 PM] But that isn't the same thing. Ark is literally building THE tools for people to then do that. mak [8:04 PM] @Matthew_DC Just to clarify I appreciate the work you guys are doing but I want to make an informed investment decision about holding the ark token arigard [8:04 PM] As a platform. Jarunik [8:04 PM] yes ... that is the idea how to grow arigard [8:04 PM] if you cloned Bitcoin back in the day you were a seperate currency. Jarunik [8:04 PM] provide good tools for others to create chains arigard [8:04 PM] This is a platform, its totally different. And what we are discuswsing here is who runs that platform. Matthew_DC [8:05 PM] If someone launched an Ethereum chain right now and gained adoption there is a huge potential that all tokens decide to move their ERC20 tokens to the new chain and it becomes the new Ethereum and you have in essence lost all value because Ethereum is not capable of being used on the bridge chain as a currency. ARK maintains it's value if for no other reason than the pegged value to any chain we personally create to include VM chain, token issuance chain, etc. arigard [8:05 PM] If it's built by Ark, does Ark always retain control? if not, why? What happens if Ark ends up building tools for a subsidary project that propels itself above them. Investors will just move to that coin. Matthew_DC [8:05 PM] Because it's an open decentralized system. The problem is people don't actually believe in decentralization if it possibly harms their potential for monetary gain. rob [ Ark Labs ] [8:06 PM] we hope bridgechains get popular because that also means more for Ark in many ways. arigard [8:06 PM] You can be decentralized without being 100% altruistic. It's not mutually exclusive. mak [8:06 PM] @goldenpepe Since you guys claim that there's no solution for this how about I present one which @Matthew_DC can decide if it's useful or not. Make delegate voting for the ArkVM happen on the main chain. So anyone who wants to become a delegate for the VM needs to hold money on the main chain. arigard [8:07 PM] It just seems people are being dogmatic about this. And if this isn't about investment. Why have an ICO? Matthew_DC [8:07 PM] Ethereum being the core chain for all ERC20 token based businesses centralizes the industry in a massive way. Not only is Ethereum itself centralized in the way it's mining structure was developed, but it also is centralized in that if the Ethereum network is compromised, thousands of companies assets and business are now compromised. We don't believe that is the future. mak [8:07 PM] I'm not saying that this should be done for all sidechains. Just for the VM and it will be a special case. Matthew_DC [8:07 PM] We believe in a different business model. That has been at the core of every description and explanation I have given from day 1. arigard [8:07 PM] Ok and that's fine, but my point is this should be made very clear if it's the case. From the team officially. goldenpepe [8:07 PM] @mak now you're strawmanning me Matthew_DC [8:07 PM] Where is it not clear? goldenpepe [8:08 PM] I was addressing the fact that the idea that bridgechains shouldnt be independent and should be tied to Ark being in conflict with the Ark team's idea that the main chain should not be bloated with dapps The only plausible solution to that right now is Ethereum Plasma Sharding yokoama (thefoundry Delegate) [8:09 PM] Sharting mak [8:09 PM] "We believe in a different business model." I respect that. But it changes the ark's value proposition to just being a source of funding to the ark team and a means of speculation. goldenpepe [8:09 PM] Shards in ethereum are like bridgechains but the coins are all erc20s that rely on ethereum Matthew_DC [8:09 PM] People said ARK's DPoS mechanism would be a failure when we changed the voting structure because they said it wouldn't be secure enough. It has turned out to be massively secure compared to the centralized cartel run solutions of other DPoS chains. This is another fundamental issue where we believe we have a model that will work and will create value and thousands of use cases for the ARK token in a seamless way for the average user. goldenpepe [8:09 PM] and the shard blocks dont interfere or bloat up the "main" eth chain mak [8:09 PM] @goldenpepe I'm not suggesting deploying dapps on main chain. Just that the voting should take place there so there is always incentive to keep money on the main chain. Matthew_DC [8:10 PM] At no point did we say ARK was gas and have constantly made sure to outline the differences between ARK and Ethereum. I believe the Eth model is flawed. goldenpepe [8:11 PM] The current ethereum model is flawed If sharding works then it's going to solve a lot of its issues (i dont hold any ethereum btw) arigard [8:12 PM] At no point have we actually had an updated white paper discussing this question in detail, clearly. It's not on the website and if it is it's buried somewhere in a blog post. The fact these discussions keep cropping up is proof of this. nukacolaplease [8:12 PM] I think we don't understand clearly what makes Ark important after the launch of the sidechains, Ark will be only an "exchange token"? The sidechain doesn't need Ark for operating goldenpepe [8:12 PM] +1 on needing a new whitepaper Matthew_DC [8:12 PM] replied to a thread: This is a means of centralization of the network. Instead, by utilizing a form of pegged bridge chains, we can maintain a similar effect without creating centralization and reliance on 1 chain for others to properly function. arkenstone [8:12 PM] I think these things should be clearly written in a new WB and officially made public and promoted goldenpepe [8:12 PM] A new whitepaper would clear up so much FUD pieface [8:13 PM] Yeah I think a new WP is needed for sure arigard [8:13 PM] So don't start going "Oh everybody knows this, it's clear" Show me where on the front page of the website it tells you how the token mechanics will work in the ecosystem? It's not good it being on some powerpoint on a google drive, or hidden in comments in the slack. mak [8:13 PM] I though there wasn't going to be a new whitepaper. arigard [8:13 PM] It needs to be clear to investors how it works, exactly. goldenpepe [8:13 PM] I agree with arigard here I only know what I know because I live on slack Matthew_DC [8:13 PM] The solutions are still in development and there are always opportunities to continue to adapt the model, that's why I have these conversations and ask for feedback regularly, but the core fundamental belief of how open and free decentralized markets should work most likely won't change. arkenstone [8:13 PM] Same here goldenpepe [8:14 PM] The vast majority of ark holders have no idea they just bought bc of the cool red triangle arigard [8:14 PM] Stop playing cute, this is people's money you are asking for. So at least give them the benefit of being honest that there is no inherent business model reason why Ark will be necessary in the future. And let them make their decisions. roks0n (deadlock) [8:14 PM] I agree, it took me months of following discussion on slack and digging around reddit to get information arigard [8:14 PM] With proper information. mak [8:14 PM] replied to a thread: It's centralizing value onto one chain but doesn't bottleneck the ecosystem so I don't see anything being wrong with that. Matthew_DC [8:15 PM] replied to a thread: I'm not arguing with you and I made a clear post here within the last 2 days that our website messaging is shit and needs completely redone. If the ARK network is compromised or the consensus mechanism of the ARK main net is compromised then all subsequent networks reliant on that consensus would be compromised as well. mad4thrash [8:15 PM] In my opinion Ark's value come from (in the future) the fact that by holding one coin I can interact with every bridgechain plus any ACES services Matthew_DC [8:16 PM] So what I am saying is that we have to be cautious of these kinds of decisions and ensure that we aren't inadvertently creating attack vectors to take down partners, businesses, and other industries using the technology. I'm sorry guys, I have to go, but I would love to continue this conversation on Reddit or here at a later time. mak [8:16 PM] "all subsequent networks reliant on that consensus would be compromised as well" ^ Correction: only the VM chain will be compromised since I'm not advocating that all bridgechains should vote on the main chain. Matthew_DC [8:19 PM] In an isolated case, if we can map it out and vet the concept, I'm more than happy to hear it out and have the conversation. Solowatch [8:19 PM] So I think we can all agree an updated Whitepaper is due Matthew_DC [8:20 PM] This is a community project and we are shaping pieces of it together as we continue to build. We have already made changes based on community feedback on many occasions. So I would love to see someone post a proposal to reddit or even as an AIP at some point that we could discuss. Jarunik [8:20 PM] If you write a white paper it will be outdated soon :smile: Solowatch [8:21 PM] Well a V2 whitepaper shouldn’t be outdated soon I don’t care about a V1 or V1.5 whitepaper lol I want a whitepaper for V2 that’s clearly explaining all these concerns that the community has arkenstone [8:22 PM] :this: Solowatch [8:23 PM] I wrote a few questions down that I’ll post in here later today that @rob [ Ark Labs ] asked for. Please add to it if I missed anything once I do. arkenstone [8:23 PM] And I think now it's the time do it. Present it with full package on mainet launch.. (edited) Solowatch [8:23 PM] Or PM and I’ll add them before posting mak [8:25 PM] Anyways thanks for listening and responding @Matthew_DC. Some of us have been trying to discuss this with the ark team but didn't get much feedback until today. arigard [8:25 PM] Yeah +1 arkenstone [8:28 PM] Alot of early investors are getting worried
I wrote a 30,000 ft. "executive summary" intro document for cryptos. Not for you, for your non-technical parents or friends.
This document was originally written for my dad, an intelligent guy who was utterly baffled about the cryptocurrency world. The aim was to be extremely concise, giving a broad overview of the industry and some popular coins while staying non-technical. For many of you there will be nothing new here, but recognize that you are in the 0.001% of the population heavily into crypto technology. I've reproduced it for Reddit below, or you can find the original post here on my website. Download the PDF there or hit the direct link: .PDF version. Donations happily accepted:
This document is purely informational. At the time of writing there are over 1000 cryptocurrencies (“cryptos”) in a highly volatile, high risk market. Many of the smaller “altcoins” require significant technical knowledge to store and transact safely. I advise you to carefully scrutinize each crypto’s flavor of blockchain, potential utility, team of developers, and guiding philosophy, before making any investment  decisions. With that out of the way, what follows are brief, extremely high-level summaries of some cryptos which have my interest, listed in current market cap order. But first, some info: Each crypto is a different implementation of a blockchain network. Originally developed as decentralized digital cash, these technologies have evolved into much broader platforms, powering the future of decentralized applications across every industry in the global economy. Without getting into the weeds,  most cryptos work on similar principles: Distributed Ledgers Each node on a blockchain network has a copy of every transaction, which enables a network of trust that eliminates fraud.  Decentralized “Miners” comprise the infrastructure of a blockchain network.  They are monetarily incentivized to add computing power to the network, simultaneously securing and processing each transaction.  Peer-to-peer Cryptos act like digital cash-- they require no third party to transact and are relatively untraceable. Unlike cash, you can back them up. Global Transactions are processed cheaply and instantly, anywhere on Earth. Using cryptos, an African peasant and a San Francisco engineer have the same access to capital, markets, and network services. Secure Blockchains are predicated on the same cryptographic technology that secures your sensitive data and government secrets. They have passed seven years of real-world penetration testing with no failures. 
The first cryptocurrency. As with first movers in any technology, there are associated pros and cons. Bitcoin has by far the strongest brand recognition and deepest market penetration, and it is the only crypto which can be used directly as a currency at over 100,000 physical and web stores around the world. In Venezuela and Zimbabwe, where geopolitical events have created hyperinflation in the centralized fiat currency, citizens have moved to Bitcoin as a de facto transaction standard.  However, Bitcoin unveiled a number of issues that have been solved by subsequent cryptos. It is experiencing significant scaling issues, resulting in high fees and long confirmation times. The argument over potential solutions created a rift in the Bitcoin developer community, who “forked” the network into two separate blockchains amidst drama and politicking in October 2017. Potential solutions to these issues abound, with some already in place, and others nearing deployment. Bitcoin currently has the highest market cap, and since it is easy to buy with fiat currency, the price of many smaller cryptos (“altcoins”) are loosely pegged to its price. This will change in the coming year(s).
Where Bitcoin is a currency, Ethereum is a platform, designed as a foundational protocol on which to develop decentralized applications (“Dapps”). Anyone can write code and deploy their program on the global network for extremely low fees. Just like Twitter wouldn’t exist without the open platform of the internet, the next world-changing Dapp can’t exist without Ethereum. CurrentDapps include a global market for idle computing power and storage, peer-to-peer real estate transactions (no trusted third party for escrow), identity networks for governments and corporations (think digital Social Security card), and monetization strategies for the internet which replace advertising. Think back 10 years to the advent of smartphones, and then to our culture today-- Ethereum could have a similar network effect on humanity. Ethereum is currently the #2 market cap crypto below Bitcoin, and many believe it will surpass it in 2018. It has a large, active group of developers working to solve scaling issues,  maintain security, and create entirely new programming conventions. If successful, platforms like Ethereum may well be the foundation of the decentralized internet of the future.
Ripple is significantly more centralized than most crypto networks, designed as a backbone for the global banking and financial technology (“fintech”) industries. It is a network for exchanging between fiat currencies and other asset classes instantly and cheaply, especially when transacting cross-border and between separate institutions. It uses large banks and remittance companies as “anchors” to allow trading between any asset on the network, and big names like Bank of America, American Express, RBC, and UBS are partners. The utility of this network is global and massive in scale. It is extremely important to note that not all cryptos have the same number of tokens. Ripple has 100 Billion tokens compared to Bitcoin’s 21 Million. Do not directly compare price between cryptos. XRP will likely never reach $1k,  but the price will rise commensurate with its utility as a financial tool. In some sense, Ripple is anathema to the original philosophical vision of this technology space. And while I agree with the cyberpunk notion of decentralized currencies, separation of money and state, this is the natural progression of the crypto world. The internet was an incredible decentralized wild west of Usenet groups and listservs before Eternal September and the dot-com boom, but its maturation affected every part of global society.
Cardano’s main claim to fame: it is the only crypto developed using academic methodologies by a global collective of engineers and researchers, built on a foundation of industry-leading, peer-reviewed cryptographic research. The network was designed from first-principles to allow scalability, system upgrades, and to balance the privacy of its users with the security needs of regulators. One part of this ecosystem is the Cardano Foundation, a Swiss non-profit founded to work proactively with governments and regulatory bodies to institute legal frameworks around the crypto industry. Detractors of Cardano claim that it doesn’t do anything innovative, but supporters see the academic backing and focus on regulation development as uniquely valuable.
Stellar Lumens (XLM)
Stellar Lumens and Ripple were founded by the same person. They initially shared the same code, but today the two are distinct in their technical back-end as well as their guiding philosophy and development goals. Ripple is closed-source, for-profit, deflationary, and intended for use by large financial institutions. Stellar is open-source, non-profit, inflationary, and intended to promote international wealth distribution. As such, they are not direct competitors. IBM is a major partner to Stellar. Their network is already processing live transactions in 12 currency corridors across the South Pacific, with plans to process 60% of all cross-border payments in the South Pacific’s retail foreign exchange corridor by Q2 2018. Beyond its utility as a financial tool, the Stellar network may become a competitor to Ethereum as a platform for application development and Initial Coin Offerings (“ICOs”). The theoretical maximum throughput for the network is higher, and it takes less computational power to run. The Stellar development team is highly active, has written extensive documentation for third-party developers, and has an impressive list of advisors, including Patrick Collison (Stripe), Sam Altman (Y Combinator), and other giants in the software development community.
Iota was developed as the infrastructure backbone for the Internet of Things (IoT), sometimes called the machine economy. As the world of inanimate objects is networked together, their need to communicate grows exponentially. Fridges, thermostats, self-driving cars, printers, planes, and industrial sensors all need a secure protocol with which to transact information. Iota uses a “Tangle” instead of a traditional blockchain, and this is the main innovation driving the crypto’s value. Each device that sends a transaction confirms two other transactions in the Tanlge. This removes the need for miners, and enables unique features like zero fees and infinite scalability. The supply of tokens is fixed forever at 2.8*1015, a staggeringly large number (almost three thousand trillion), and the price you see reported is technically “MIOT”, or the price for a million tokens.
The most successful privacy-focused cryptocurrency. In Bitcoin and most other cryptos, anyone can examine the public ledger and trace specific coins through the network. If your identity can be attached to a public address on that network, an accurate picture of your transaction history can be built-- who, what, and when. Monero builds anonymity into the system using strong cryptographic principles, which makes it functionally impossible to trace coins,  attach names to wallets, or extract metadata from transactions. The development team actively publishes in the cryptography research community. Anonymous transactions are not new-- we call it cash. Only in the past two decades has anonymity grown scarce in the first-world with the rise of credit cards and ubiquitous digital records. Personal data is becoming the most valuable resource on Earth, and there are many legitimate reasons for law-abiding citizens to want digital privacy, but it is true that with anonymity comes bad actors-- Monero is the currency of choice for the majority of black market (“darknet”) transactions. Similarly, US Dollars are the main vehicle for the $320B annual drug trade. An investment here should be based on the underlying cryptographic research and technology behind this coin, as well as competitors like Zcash. 
Zero fees and instantaneous transfer make RaiBlocks extremely attractive for exchange of value, in many senses outperforming Bitcoin at its original intended purpose. This crypto has seen an explosion in price and exposure over the past month, and it may become the network of choice for transferring value within and between crypto exchanges. Just in the first week of 2018: the CEO of Ledger (makers of the most popular hardware wallet on the market) waived the $50k code review fee to get RaiBlocks on his product, and XRB got listed on Binance and Kucoin, two of the largest altcoin exchanges globally. This is one to watch for 2018. 
Developed as a single answer to the problem of supply-chain logistics, VeChain is knocking on the door of a fast-growing $8 trillion industry. Every shipping container and packaged product in the world requires constant tracking and verification. A smart economy for logistics built on the blockchain promises greater efficiency and lower cost through the entire process flow. Don’t take my word for it-- VeChain has investment from PwC (5th largest US corporation), Groupe Renault, Kuehne & Nagel (world’s largest freight company), and DIG (China’s largest wine importer). The Chinese government has mandated VeChain to serve as blockchain technology partner to the city of Gui’an, a special economic zone and testbed for China’s smart city of the future. This crypto has some of the strongest commercial partnerships in the industry, and a large active development team.
“Investment” is a misnomer. Cryptos are traded like securities, but grant you no equity (like trading currency).
It is impossible to double-spend or create a fake transaction, as each ledger is confirmed against every other ledger.
Some utility token blockchains use DAG networks or similar non-linear networks which don’t require mining.
In practice, these are giant warehouses full of specialized computers constantly processing transactions. Miners locate to the cheapest electricity source, and the bulk of mining currently occurs in China.
Centralized second-layer exchange websites have been hacked, but the core technology is untouched.
Hello! My name is Kristina Semenova, I am the Head of Investors Relation Department at Platinum, the world’s number one business facilitator. Our team knows how to start ICO/STO in 2019! Why are we so sure? Well, our experience speaks for itself: Platinum.fund But what is the difference between ico and sto? What is the cornerstone of ICO marketing strategy? You will know this after finishing the UBAI courses! Here’s just a quick preview of our Short Course lesson. Real World Examples Multinational accounting firm Ernst and Young found that $400 million of the $3.7 billion USD raised from ICOs (as of January 22, 2018) had been stolen. That is, up to 10% of all ICO funding is virtually being stolen from investors. Though ICO scams are the most common method of theft in the crypto world, some projects will actually operate for a period of time before disappearing with the money. Like in a Ponzi scheme, an exit scam may be planned for later, sometime after a manipulated pump; or some other time the team believes is most opportune to take the money and run. Giza: Giza marketed itself as a platform within which different cryptocurrencies could be stored securely. But after raising $2.4 million in one month, the team deleted the website and stopped replying to emails. Investors were duped by a very convincing whitepaper, and actors had been hired to appear in photographs promoting the project. No investor funds have ever been recovered. Centra: The SEC put an end to fundraising for the Centra ICO and charged the founders Robert Farkas and Sohrab Sharma with orchestrating a fraudulent ICO after they raised $32 million USD. They were promoting the ability to develop financial products backed by VISA and Mastercard, though it was later found that neither partnership was real. One of the major red flags in the Centra project was the use of celebrity endorsements for publicity, reportedly paying champion boxer Floyd Mayweather a significant sum to promote their project. Who wants to leave their Blockchain investment decisions up to Floyd Mayweather, regardless of his unbelievable skill as a boxer and regardless of his own financial success? He should still not influence where you invest your money! Ponzi Schemes: Bitconnect: This is the most infamous Ponzi scheme in the history of cryptocurrency, and certainly the most damaging. Bitconnect was a Bitcoin-based project that rose to an all-time high of $463 per token on the back of a fictitious trading bot. The Bitconnect scam operated by paying dividends to users, proportional to the number of tokens they held and the number of referrals they made. The BCC tokens were exchanged for the users’ Bitcoin, and the highly sophisticated and wildly successful trading bot would trade BTC for them and distribute profits as dividends. The value of the dividends offered was approximately 1% of the initial investment per day. In other words, that is approximately 3,780% per year in cumulative gain! The referral system was capitalized upon most heavily by many of the biggest crypto YouTube channels, including CryptoNick and Trevon James, both of whom are now under investigation by the Federal Bureau of Investigation. Shortly after the Bitconnect Token reached its all-time high, they received cease and desist orders from the security regulators of Texas and North Carolina, which caused the owners of the Bitconnect exchange to shut down operations, and the price to plummet. Davorcoin: Davorcoin was a lending platform very similar to Bitconnect. And Davorcoin was farcically promoted by the same Trevon James crypto Youtuber who promoted Bitconnect, and is currently under investigation by the FBI for promoting Ponzi schemes. The Texas State Securities Board, in likening Davor to Bitconnect, stated that “DavorCoin is telling investors they can earn lucrative profits by investing in a lending program based on a new cryptocurrency known as davorcoin. Investors allegedly purchase davorcoin and then lend it to DavorCoin”. Davorcoin promptly plunged from an all-time high of $180 to very close to zero after a cease and desist order was made against them on the 2nd of February 2018. Useless Ethereum Token: Despite brazenly stating in the name of the project that the token has no use, the UET managed to raise $340,000 in its crowdsale, and saw a significant pump of over 300% on the HitBTC exchange in February of 2018. The scam was an obvious case of pump and dump, with the total trading volume for UET crashing back down to as low as $3 per day, after reaching as high as $350,000 per day during the pump. It is currently an unfortunate consequence of the decentralized nature of cryptocurrency, but there is a distinct lack of recourse for scammed investors. It is wise to become as well-acquainted with the various indicators of good and bad ICOs as you possibly can. In weighing the factors that will allow you to avoid expensive mistakes, ask yourself in whose favor are the terms of the ICO slanted, yours or the teams? To what extent are you actually likely to profit from this investment? Cryptocurrency is inherently a grey area, whether you are investing in it or not. Investing is another inherently grey area, no matter what the area or object of investing might be. Laws and regulations are not always able to keep up. Trying to define and prove what was or was not a scam is not likely to be as simple as the scammed investor would want it to be. A project can be set up in certain ways to avoid being technically classified or provable as a scam, but the unprepared investor can still be burnt or scammed just as badly. Now we look at more individual indicators that can help you form a valid impression whether or not an ICO or even a fully-fledged exchange-listed coin is a scam or a bona fide investment opportunity. Common Signposts Contrasting Scam & Legitimate Projects Presale Bonus/Token Release If the ICO allots massive bonuses to team members, you may leave yourself open to getting dumped on by presale investors if you buy when the project tokens are listed on an exchange. Likewise, if the project has a short lock-up period for developers and founders, you run the risk of them selling as soon as the token is listed on a major exchange. The token release schedule for the founders of a worthwhile project should show long-term team commitment to that project. The Jibrel Network team tokens will be locked up for 5 years before release, and they had no early investor bonus in the main sale. Both of these factors instilled confidence in the JNT ICO investors, and the tokens were sold out weeks before the ICO was due to end. No Presale lock up If Presale investor tokens are not locked up at all for any period after listing, that could easily be a set up for an exit scam after the initial listing. No presale lockup for early investor tokens is a crystal clear warning, the project may be fatally rigged toward those in the inner circle, with little commitment to the long term health or success of that project. Unsolicited Offers or Unasked for Additions to Groups Characters running scam projects will often add you to Telegram groups out of the blue or send you unsolicited emails with information about their project. Telegram is the most widely used messaging app in the cryptocurrency community and you should familiarize yourself with it to keep yourself in the loop for specific projects in which you invest as well as all kinds of other relevant crypto info. You can adjust the settings on the Telegram app to disallow anonymous additions to cryptocurrency projects if you find yourself bombarded with offers by scammers. Reputable projects at the ICO stage will spread by word of mouth, or by eloquent and meaningful articles posted on their Medium page. A project with serious potential does not need to actively seek participants for their ICO like that. They will often be able to fill their ICO hard cap in a matter of hours, or even just minutes! Anonymous Team Alarm bells, again, immediately, if the project has minimal online presence. The individual team members could be mere fabrications. The entire project could be a farce by utterly inexperienced characters. What if the project leaders are simply unaware of the importance of a strong social media profile? That in itself would be too strange to ignore. Top-level projects will have team members with experience in crypto and the LinkedIn accounts for those members will be easily accessible right there on the project website. You should be able to easily see and evaluate each individual’s experience in their field and ascertain what they bring to the project team. Bitconnect’s anonymous team should have been the only deterrent prospective investors needed to discourage them from putting money into that doomed project. Ethhorse, a current project with anonymous founders and operators should be steered clear of at all costs for the same reasons. Community Atmosphere The subreddits or Telegram groups of scam projects will often feature moderators that do not allow any kind of criticism in the group chat. If, in the process of your due diligence, you encounter didactic admins that only wish to silence your questioning of certain aspects of the whitepaper or mechanism of the tokenomics , you should be concerned. Similarly if you see a coherent critical reply attacked by many different users who refuse to engage the substance of the point being made, that may be a subreddit infested with bots. Projects that have nothing to hide will allow free debate in the chat. Ideally, they hope to develop a positive community that is itself an asset to the long-term success and overall strength of the project. Good projects do not need to automatically brand all criticism as Fear Uncertainty and Doubt (FUD). Whitepaper One common tactic of scammers is to produce a whitepaper that uses too many buzzwords, and deliberately obfuscates and overcomplicates the explanation of the problem and/or its solution. A good whitepaper clearly and concisely lays out the problem and answer, as well as provides compelling arguments why a Blockchain solution is preferable to the current solution. Another point of concern is a whitepaper that gives unrealistic time frames and goals. Bitconnect’s almost comically optimistic profit projections are a prime example of this, as are the 1,354% yearly gains promised by Plexcoin. Respectable projects will set out development timescales in terms of quarters or years, rather than offering immediate profit projections, which are simply a red flag. Advisors/Connections in the Cryptoworld The most prestigious projects will already have partnerships made before the ICO stage, and the worst ones, i.e. the scams, will not mention any such partnerships. Icon (ICX) for example was spawned from a South Korean project named The Loop, a collaboration between 3 Korean universities and the DAYLIFinancial Group. They boasted an advisory panel consisting of the legendary investor Don Tapscott, Jehan Chu and crowdfunding expert Jason Best. On top of a solid team of advisors, good projects will also be visible at major Blockchain events such as the Consensus, and the World Blockchain Forum, etc. Scam projects will be unable to inspire this same level in confidence. As an investor, you should sense a certain presence and expect a certain feeling of trust that should guide you in your investments. After all, it is actually a people-to-people thing you are doing. Key Stress points upon the Timeline to Identify Scam Projects Post Whitepaper Release The period in the immediate aftermath of the release of the whitepaper can also be decisive in establishing the validity of a project. How a team copes with the roadmap that they have laid out for themselves is key. Valuable insight into the operational efficiency and commitment to the project can be gleaned from the quality of and amount of code committed to GitHub. If you have any experience in computer programming you can see how clean and orderly the code is, which gives insight into the skill of the developers, and in turn the quality of project leaders’ decision-making in hiring team members. Scam projects will have little or no code committed to GitHub, or at best it will be copied and pasted from other projects just to cover their tracks. Start of ICO Sometimes, a scam project, or other project in which you would be better off not investing, will change the terms of the ICO just before the ICO starts. The Key (TKY) ICO doubled the price of tokens on the day before the ICO was due to take place, because the price of NEO had risen so drastically. Currently, the TKY token price is still only half of its ICO price. Initial investors are faced with the prospect of a 50% loss on their investment. Exchange Listing Some particularly greedy scammers will create a scam project with the intent of selling tokens in the ICO for BTC and ETH, and then pumping and dumping their share of the tokens immediately after listing. The team of fraudsters behind Monero Gold used this method after the crowdfunding of their useless ERC-20 token. After listing on CoinExchange.io, the team dumped their tokens until the exchange finally ceased trading. Although it is not uncommon for ICO tokens to sold after listing (just like can happen with shares of stock after an IPO), if the price does not stabilize and massive sell walls are continually placed, a scam is likely taking place and the token is being dumped. Fake Ethereum Twitter giveaway You may have noticed Ethereum creator Vitalik Buterin’s twitter handle has been changed to Vitalik “Not giving away Eth” Buterin in recent months. This is because a group of devious scammers had created fake accounts with almost exact replicas of his profile (deviating by only one character). The fake accounts promised to deposit 1 whole ETH for every 0.1 ETH the potential sucker deposited into the wallet address provided by the scammer. These fake account “Ether giveaway” scam tweets were set up to be sent in just a matter of seconds after the real person tweeted, and usually always appear immediately after the tweet of the real public figure. Fake bot profiles then came into play, thanking the fake Vitalik, or fake Elon Musk, for holding up their end of the bargain and depositing the ETH as promised. One scammer, or group of scammers, managed to fill a wallet up with almost $20 thousand worth of ETH, which they transferred out, never to be seen or heard from again. Effect of Scam Customers, Upon the Affected Parties Of course, this is no fun for the targeted public figure either. They need to take steps to avoid being targeted again. This will mean changing their handle, their username, or making their accounts private. However, the injured party with whom we are most concerned is the unfortunate scammed social media user, who has no chance whatsoever of getting his or her funds back, ever. It is a harsh lesson to learn. But it is a fact of crypto reality. Nearly every one that trades crypto will at least be exposed to frauds or scams in one way or another. In this case, we think it is better to learn about scams by studying them, rather than learn from your own unfortunate and expensive experience. In the case of Mr. Buterin, these incidents were awful public relations for the Ethereum project. It had only been a few years since cryptocurrency as a whole was primarily associated with criminality and seedy transactions on the Darkweb. Any connection with unscrupulous behavior is best avoided at all costs. Negative associations could have been particularly damaging for Ethereum’s brand because the vast majority of ICO fraud is committed using the ERC-20 token as the template for the scam tokens. Any and all the scamming or fraudulent behavior in the cryptocurrency ecosystem is bound to have a negative impact on the speed at which mainstream uptake finally takes place. Cryptocurrencies, as an emerging asset class, will be painted in the worst possible light. Crypto is aiming to, and is in fact in the process of, causing great disruption in traditional centralized finance and business. Mainstream media organizations are also part of that traditional centralized economy. Press coverage will be damning. Something is happening here, but Mr. Jones doesn’t know what it is. Legal Recourse for Scams We clearly understand, there is a possibility of being scammed. We know the scams are happening. The SEC has made some arrests and actually charged people for operating fraudulent ICOs. But it is a struggle to deal with the flood of ICOs coming from anywhere at any time. The SEC filed charges against two founders of a purported financial services startup for orchestrating a fraudulent ICO that raised more than $32million from thousands of investors. As you know from the ICOs we have covered so far, the lack of regulation allows for direct contact and dealing between the entrepreneurs, business owners and potential investors. While we believe this is a blessing according to the founding principles of Bitcoin and other alternate Cryptocurrencies, because it frees us from traditional roadblocks, middle-men, and all kinds of time-consuming procedures; it also leaves investors in a place where there is often little to no hope of ever recovering funds lost in fraudulent schemes. Actions after a Successful ICO Good post-ICO practice is characterized by stringent security, well thought-out legal strategy and clear communication. Many projects have paid the price in damage to their reputation for failing to adequately guard customer information, leaving themselves open to phishing attacks by fraudsters. Investors in the Enigma project had half a million dollars stolen from them; and a whopping $8.4 million was defrauded from investors in Veritaseum via phishing attacks. After a successful token distribution, the team’s main focus is initially on switching the enterprise from one primarily focused on fundraising, to superficially at least, a fully-fledged, functioning business. This involves removing most of the token sale-related content from their main webpage, sending newsletters to all successful ICO participants, and sending refunds to those who may have missed the deadline or the hardcap. Then, with the stressful and complicated fundraising stage finally concluded, a portion of the funds raised can be assigned to fuel the growth of the project community. This can involve hiring community managers, forum admins, and social media managers to outsource the job of keeping investors in the loop. The founders can focus on growth strategy and product development. The cultivation of a thriving and energetic community is extremely important. The community will give you free marketing for your product and your business. Community members who believe in the project, and are engaged by professional moderators, can give you very effective promotion to other prospective investors. Communication with community members is a great way to test ideas and gauge sentiment related to various aspects of your project. The project leads must set aside adequate funds for lawyers. The project will need to address potential future or imminent problems with regulators, at the very least. The transition from fundraising project to full-fledged business can be incredibly challenging, and even more stressful than the ICO itself. The main thing to remember is that your pre-sale and ICO investors are not just silent investors waiting for a return. They are the early adopters of your solution, of your product; they are the community and promoters of your project; and they are the individuals with a vested interest in the financial success of your venture. The ICO environment is not as heavily regulated, so quarterly and/or semi-annual reporting is not required the way it is in the traditional world. That means your own style of effective communication about the progress and key developments on your project matters even more. In the ICO world, you communicate with your press releases, social media, and Medium posts. You also communicate by the very nature of your relations with your exchange, and relationships with your cornerstone investors. Effective communication and good business relationships can play a prominent role in the success or failure of your venture (by token liquidity and valuation). If your investors start to lose interest, and stop trading your token on the exchange, liquidity will dry up and cause increasingly volatile price swings. You need to keep certain things in mind, and follow effective practices to maintain a happy and motivated community. Social Media & Medium In addition to your website, your social media & Medium blog most likely formed a significant part of your ICO preparations. Your purpose pivots after the ICO from one of promotion to one of communication. Consistent, informative and material Medium blogs, also Facebook and Twitter updates, ensure that investors remain engaged and well-informed of what the company is up to. Frequent activity in this space makes investors feel much more comfortable. You can foster a kind of organic community expansion that is consistently advertising your project to potential new members. Cornerstone Investors & Exchanges As we mentioned, your relationship with investors in the ICO world is different from that of the traditional silent IPO minority equity partners. Consistent, Transparent & Honest communication is incredibly important here. Even if an ICO is struggling to overcome a problem or whatever issues are occurring, honest communication from the team is key to business survival. You should think of and treat your exchange like a business partner too, a very important one at that. Exchanges provide liquidity for you and your investors. That liquidity is like the blood for your business. Many top exchanges demand nothing less than absolute honesty and integrity, it is imperative to maintain strong and comfortable relationships with exchanges. Everything we have said so far, also applies to your Telegram channel and forums too. These give you another great opportunity to build a thriving community. Team members and investors can enjoy lively debates in their Telegram channels. This can be constructive discussion, or critical commentary too. But it is always valuable as a direct link between the team and the community. It is always good to know how people are feeling and what they expect from you and your project. You are able to use your Telegram channel and forums to consistently adapt your marketing and communication strategy. Keep your investors as happy and comfortable as possible, and you will be more likely to attract new investors and allocations. Other forums around the internet operate more or less in the same manner as Telegram. After a successful funding round with the hardcap reached and time to spare, legal counsel has been secured, and the community is flourishing, the team will prepare for their first listing by paying the exchange fee and waiting for the announcement by the exchange. Unless they are willing to pay exorbitant fees for an immediate listing on Binance for example, teams will usually settle for an initial listing on a second-tier exchange. The fee charged by an exchange depends on many different factors that we will cover in more detail in the next section. ICO Company actions after a Successful ICO Real World Case Study The Basic Attention Token (BAT) project, when used in conjunction with the Brave Browser, allows users to pay micro-fees in BAT to their most-used sites. The idea was conceived by Brendan Eich, the inventor of Javascipt and former CEO of Mozilla Firefox. Investors absolutely pounced on it at ICO and the project raised an amazing $35million in under 30 seconds. The BAT/Brave project has delivered on time on nearly all of its targets, helped in no small part by having a working product, the Brave Browser, for over a year before the token launch. The project secured a listing on the premier exchange, Binance, in November 2017. A project can suffer through a disappointing funding phase and, for example, fail to reach 75% of its hardcap. The team will be only partially funded. Though they may be able to initiate the project, the value proposition of the token has been compromised, potentially forever. The market has spoken. There is limited faith in the team’s ability to complete or carry out their project. Failure to reach a hardcap is a serious obstacle on the project road map. This will mean massive revisions to the timescales for development and listing. Such a project may have to be content listing on decentralized exchanges for a period of time and they will lose any post-ICO hype that could have helped the project price to “moon” early on. There is less money to be allocated. Each section of the business will be underfunded compared to the original plan. There can be delays in code development, exchange listing, marketing and community development as well. Calling the Tezos ICO a disappointment might seem strange considering they raised over $232million. But this open-source, smart contracts fintech platform became a victim of its own success post-ICO by devolving into multiple class-action lawsuits between the founders and its foundation chairman. They suffered from a distinct lack of clearly defined roles and expectations on key positions. There was infighting at the boardroom level. This all caused an as yet unresolved delay in listing and development. This is also one example why a capped ICO can be more desirable for investors than an uncapped ICO. If the team have a set amount of capital to work with, an amount that isn’t absolutely ridiculous, like in the case of Tezos, perhaps the resultant greed and discord is less likely. Although it may not be so easy for speculative investors to make a profit from an uncapped ICO with such a massive initial market cap, it is a very impressive feat of fundraising nonetheless. Tezos’s post ICO market cap of $232million is already 64th of all projects, and would have to perform brilliantly on listing to maintain this position. Company actions after a Failed ICO Failed ICOs can mean either fundraising initiatives that have failed to reach the softcap and will therefore not be economically viable, or fraudulent projects whose sole intention was to steal from investors and do an exit scam. We’ve already covered scams and fraud projects in detail, but what happens when an ICO just fails to raise the requisite funds? Projects that are legitimate, with honest founders and developers, refund the ETH or BTC deposited by investors as quickly as possible if the softcap is not reached. The same process that is followed by ICOs that are oversubscribed is employed by those that have failed to raise enough capital. The process of returning funds back to the sender ideally should take a period of days, but more likely will take a few weeks. The Sappy Network, advised by Dan Tapscott, failed to come anywhere near to their funding goals. They are currently in the process of sending all investor funds back to the wallets from which they came. The statement from the founders read as a textbook example of how you should react to failure with the founder stating “In the spirit of transparency and honesty, we are sharing with the community that we did not reach the soft cap, and thus we will be honoring our terms and conditions and returning the Ethers to all contributors” Exchange Listing A bottleneck developed in the ICO market after the explosion of crypto prices in 2017. There was a massive increase of ICO teams on all stages along the pathway from start-up to fully listed crypto asset. Certainly, a huge part of the value proposition for both the token and the project depends on securing a listing on an exchange. It is precisely the liquidity of the token as a valuable asset on a free market exchange, that determines or even defines its value. The liquidity is what makes tokens attractive to investors, but that liquidity simply does not exist without a platform for the exchange. Unfortunately for new projects, the balance of power is heavily weighted in favor of large centralized exchanges that can pick and choose which tokens to list, and the timescale within which listing will occur. Each large exchange has its own list of pros and cons as well as its own specific procedure for coin/token listing. They also have their own particular ethos regarding the type of projects they prefer to list. ERC-20 tokens will be available for trade immediately on decentralized exchanges (IDEX Forkdelta) but those platforms are generally quite low volume, and certainly not a long term solution. Projects must often pay huge fees to be listed on the larger centralized exchanges. At first those fees will be prohibitive. The usual route is to initially list on a more reasonably priced smaller exchange like Kucoin or Gate.io. Listing Process Major centralized exchanges have the power to list anything they want, and they also each have a unique structure that projects must adhere to if they wish to be listed. Each potential new listing will undergo a rigorous examination by the exchange operators to test the feasibility for listing the token. An exchange will likely have forms available on its website that you can fill out to give them all the necessary initial information. If a particular project and token qualify for listing, the team will invariably be put under a NDA, Non-Disclosure Agreement, to avoid any insider trading or other regulatory problem s. In the case of larger exchanges like Binance, there is a period within which owners of a newly listed coin or token can transfer them to the exchange in preparation for trading. This is a fantastic opportunity for traders to make use of the likely pump that occurs after a new token is listed on a large exchange. It is common to see up to 100% increases on the first day of trading, and a subsequent dump of up to 50% or more can follow. This allows traders holding the coin already, to sell for a good profit, and maybe buy back in at a much lower price too, if they think that is a good idea. Exchange Fees There are no definitive figures available to the public regarding fees that major exchanges charge new projects to list. Binance, Bitfinex, Kraken and Bittrex have all been quoted as saying that they do not charge any fee at all but this is almost definitely untrue. Knowledgeable industry insiders estimate between $500,000 and $1,000,000 USD for listing on a top-tier exchange. (There have been more rumors of 7 figure exchange listing fees since January 2018 too). This figure will vary greatly from project to project. Various factors can affect how an exchange determines the fee for a particular project. These are some of the most important ones: Market Maker Service Required Whether or not the client project requires liquidity services directly from the exchange, or can connect proprietary ones via API, will lead to a huge reduction in listing cost. Type of Token (ERC-20 NEP-5 or DAG) Not all tokens are created equal in the listing process. ERC-20 tokens and BTC based tokens have code architecture that will almost certainly be preferred by the exchange. NEO based tokens (NEP-5) such as Ontology will be far most costly to integrate because separate new wallets have to be built to facilitate NEO transactions. The costs involved in integrating Direct Acyclic Graph projects such as Nano into the exchange structure are even worse. Expected Daily Volume Exchanges derive their profits largely from transaction fees and withdrawal fees. The trading volume a new token is likely to bring in will have a great influence on the computation of the exchange listing fee. Exchange Listing Procedures Evaluation Different exchanges have different rules for new listings. A new project must of course abide by specific rules for that exchange before they are allowed to list there. There are procedures that must generally be followed for the most noteworthy exchanges. You can get a good idea of the hurdles to be overcome before listing can take place. Ongoing relationship with Exchanges Exchanges, usually Huobi or Kucoin, will sometimes make it essential for newly listed tokens to engage in “trading competitions” after listing. Competitions can last between 2 weeks, or a month or more, aiming to increase the trading volume for that token, thereby increasing trading fees collected by the exchange, and giving the project extra publicity too. The whales may have made a nice profit already and be very happy about it; but the project token can still get stuck in a long period of stagnation and a loss of post-ICO hype. Once a coin or token has been successfully registered for trading on a particular exchange, the project must focus on maintaining regulatory compliance and paying things like annual maintenance fees too. Exchanges can investigate and delist coins or tokens to see if they have fallen below a certain standard set by the exchange. The exchange is concerned about such things as: an extended period with an extremely low volume; a team member connection to an exit scam; or other such immoral/illegal behavior. Post ICO Company Evaluation After a presumably successful ICO, the necessary funds have been obtained, and the real business, the real team challenge is now, to bring the project to life as a bona fide disruptive Blockchain endeavor! The core advantage of the ICO method of funding business startups is the lack of regulatory hurdles to navigate with regards to fundraising and fund allocation. The funds that have been raised have, in effect, been freely given to the project leads to do with what they will in a no-strings-attached transaction. Of course, there are still strings attached in that the team are tasked with making that money grow for the investors. But there is no regulatory oversight of the process. The regulatory freedom is a double edge sword. It gives a good team freedom to work however they want; and it also allows for unscrupulous thieves to use the ICO process to defraud investors of their ETH and BTC. Advantages of being Post ICO From Investor Perspective You should have little to fear in terms of fraud from a project in which you have invested, if you have done your due diligence correctly. You can expect the tokens to be distributed, and the exchange listing to take place as expected. And you know your project is totally legitimate. There are different ways to think about your ICO tokens after the crowd sale has concluded. If you are a speculative investor looking for a quick flip, you can gauge the correct moment and sell anytime you like, assuming the ICO has been well-received by the markets. From Team Perspective The post-ICO period is, from the point of view of the team, a period where stress and responsibility for the safety of investor funds is passed, in the form of ICO tokens, from the team to the investors themselves. This responsibility for tokens is replaced with the stress of building the actual company itself, and succeeding in the business as planned. A small portion of the responsibility for the project’s success is also passed on to the exchange that has listed the tokens. This is especially true if market makers have been employed by the team or the exchange to provide liquidity. After the ICO has concluded, all funds are released to the project team immediately, so they can start building their business brand, and tackling each step on the road map right away. The freedom with which startups can operate is one of the main reasons behind the explosion in Blockchain businesses in 2017. With the ICO funds safe, and money being put to work on various areas essential to the growth of the project, and the tokens already distributed to investors, the risk of fraud is greatly diminished. If KYC and Anti-money Laundering procedures have been followed correctly during the ICO phase, the risk of phishing attacks and theft will also be marginal now. At any rate, with tokens safely delivered to all participants, the responsibility has passed from the team to the investor. From Team Perspective The release of all funds and the freedom to allocate them with no supervision, as cited above, is certainly a tremendous advantage empowering the team to fulfil the entire breadth of their vision unimpeded. But it does have its drawbacks. If there is a mistake made in the allocation of funds, or an unforeseen problem arises, there is nowhere to turn to, and no means of generating further money via crowdfunding. The ICO is over; it is finished. The project simply has to work with what it has. Your community can sometimes turn against you when the market is going down. Times like that just add to the already intense pressure of presiding over a startup Blockchain business. Solution: DAICO The DAICO, or Decentralized Autonomous Organization Initial Coin Offering, is a means to integrate a more specific, rigorous and regimented smart contract schedule into the ICO process. Doing so will eliminate fraudulent ICOs, exit scams, pump and dumps, and many of the other disadvantages listed above. The DAICO method, proposed by Ethereum creator, Vitalik Buterin, will merge the core concepts of both an ICO and a DAO to leverage the most relevant features of both, in order to solve the main problems in the ICO method. For example, to eliminate the risk of an exit scam, the release of funds will be spread out over a period of time, with the next allotment only being released when a certain set of parameters are met. Buterin explains that the DAICO method will provide user protection in a manner not present in the current ICO model, ensuring funds are not misspent or used in any way contrary to the intention of investors. In simpler terms the DAICO will operate as follows: The DAICO will start with a smart contract by its executors that can set whether this is to be a capped or uncapped round of fundraising (amongst many other options) as well as including KYC requirements. After these settings have been configured, the DAICO is set into “contribution mode” and presented to the public. This stage will function identically to a normal ICO with ETH exchanged for project tokens. Once the funding period has elapsed, or the hardcap has been met, investors will have the ability to set the “tap” for the collected funds. This will set the amount per second, or amount per minute, that will be available to the executor to develop that specific portion of the project to which those funds have been assigned. If investors believe at any point that the team is misspending funds or otherwise wasting time, etc., the investors have significant options to take. Of course they could choose to release more funds to the team. But, they could also stop the tap altogether, and stop the entire ICO, by voting, and actually release all unused funds back to their own wallets from which the investment had first been made!

2nd Round of our AMA for the Nucleus Developers on Hcash
Please review the answers from the first round of the AMA here.
Reddit 2nd Round AMA Answers How about questions for Dallas, Khal, Andrew and Ryan? I’m sure everyone would appreciate a live Q&A from them.
You could try sending a request via direct message with questions on Facebook or Twitter. The Nucleus Team is focused on the technological development and planning at this time.
You stated previously that the swap values will be calculated on the “real time market value” of each coin. How will the market value be derived? Will it include exchange values from Binance, Poloniex, CoinMarketCap, or an average of these? Will the market value be derived in USD, AUG, RMB, or an average of them all?
Just to clarify for everyone that we are discussing interoperable swap values. This value will be an aggregated number like you see on CoinMarketCap or Coincap, which includes regional averages.
Is there an ETA a to when the yellow paper will be released?
ETA on the yellow paper is Q2 2018
This article says that the HSR code was copied from the DCR code in GitHub. Don’t you think you need an explanation?
The HSR code is forked from DCR. The GitHub repository was not created properly by the team prior to the Nucleus Team’s involvement. Existing GitHub issues originated from cultural differences as the research lab at the university where the work was done is not familiar with open source development practices, tools and their benefits. Unfortunately, this has resulted in less than positive relations between the DCR and HSR communities. We are following procedures going forward to ensure the original authors of open source projects are properly attributed as well as properly forked to help both repos benefit from the possibility of merging in changes from future development progress. Anything that we can do to contribute to Decred’s dev team and community will benefit both projects and we are looking forward to exploring future possibilities after the main HCash chain launch.
What features will the main chain have on it’s initial launch on February 15th?
February 15th is a tentative date. We are still referring to launch as being mid-February. The primary feature will be the first Go implementation of BLISS and quantum resistant transactions. We will also evaluate the future potential of bitcoin NG on public testnets to decide the features we propose to include in future forks in order to keep progress steady and continue developing the strength of the main chain. Segwit will still need to be activated on the main chain to provide Lightning Network and atomic swaps.
Baidu 2nd Round AMA Are there any projects you wish to launch this year?
We are looking forward to the launch of the main chain. Next, we are planning on contributing to Lightning Network development as well as the side DAG design and development. The side DAG will be available for a longer testing period to allow for new projects to begin building off the EVM. As PQ addresses are adopted we aim to implement other quantum-resistant signature options for users of the network.
What will your team devote the core of its attention on as it works this year?
The primary focus post launch will be Lightning Network and side DAG design and deployment.
I took a close look at the whitepaper. It doesn’t clearly say when the technology allowing cross-chain trading will be implemented. It also didn’t specify what development schedule is for that tech. Could you please explain it to me?
The roadmap will be updated post main chain launch. We need to make sure going forward that time frames and dates given are met timely while considering the feasibility of the tech we are trying to deliver. The Nucleus team is currently working to coordinate with the project’s university research partners around their plans and timelines for new contributions to the ecosystem that align well for the network’s users and the Some details of the interoperability were answered in the last AMA so I would refer to that. If you want specifics then that will have to wait till the yellow paper is finished.
What differentiates Hcash from Wanchain? They’ve already finished development their main network and they’ve made a lot of progress in cross-chain technologies.
Cross-chain interoperability is a challenge for the ecosystem that many projects are helping resolve. There will be different solutions. We look forward to seeing more about their Locked Accounts and signature sharing. I don’t know what they’ll be doing about BTC/ UTXO based transactions. Our design will allow atomic swaps for BTC/ UTXO transactions into a quantum resistant addresses for security. ETH interoperability will work similarly, but our EVM will be built into our side-DAG rather than an ETH blockchain. Also, we will be using bridges and sidechains for other styles of chains like NEO or maybe VEN. Another thing we would like to see is existing projects on ETH build a port on our EVM so those smart contracts can communicate directly with each other, rather than just using relays.
Does all the HSR belong to the teams, the investment foundation, and the early investors have a lock-in period?
You would have to speak to the Hcash foundation directly if you have any questions about lock up periods or allocations related to HSR. These advising, testing and developing the codebase and technical roadmap.
Based on the roadmap, quantum resistant passwords, cross-platform token transfers, and PoW mining have all been completed. Is the present rate of progress coming along as outlined? Please explain the technological hazards that still exist.
With the main chain, quantum resistance and PoW mining available on launch. The cross-chain functions will be operational for the main chain with Lightning Network and other chains will be available with the side DAG. There are a number of technical hazards to work through with respect to compatibility and optimization and these things will take time to implement. A new roadmap and outline is due soon.
Hcash has reached an agreement with Qtum for low-level interoperable contracts. Will Hcash later have similar agreements or connections with other projects such as Ethereum, IOTA, NEO, etc?
We would love opportunity to work alongside other projects. Based on the structure of chains such as NEO, it probably would require some open lines of communication between our dev community and CoZ. ETH operates in a more transparent manner and interoperability with ETH is much easier to achieve. The ultimate goal is to be the glue between all these different projects and provide an ecosystem for the community to build off of.
How are small and big coin websites or varying sizes (Poloniex, Bittrex, and Binance) doing in terms of getting registered on South Korean trading platforms?
There may have been something lost in this question’s translation - try reaching out to those website’s support contacts? That is not something we are involved with.
Does Hcash want to make a base level public chain, or make it like bitcoin?
The Hcash main chain is meant to provide integrity for this interoperable network. PoW chains do a fantastic job of this because of the time and effort it requires to actually secure the blockchain.
Thank you to everyone who participated. Please stay tuned to our channels for more information regarding the main chain launch!
From Ge You-esque Slouching to Blockchain Decentralization
These days, all my friends are very anxious. I heard that they stay up till 3am working on the blockchain, sending ICOs, talking about things like “if it rises or falls within the range of 50%, it’s called a stable sideways move”, and “the profit rate will at least be 100 times”. They also talk about the next-generation Internet, the greatest technology revolution since the Industrial Revolution. So, how does this decentralized blockchain influence our life? Before we talk about the challenge of decentralization, we have to figure out why the challenge of decentralization exists. Things after a long period of division, tend to unite; after a long period of union, tend to divide. It is believed in China that “domains under heaven, after a long period of division, tend to unite; after a long period of union, tend to divide.” This rule applies not only to history, but also to the development of the Internet industry. In the past, the Internet was only used to make phone calls and was monopolized by one or two large companies. This was because of the circuit switching technology back then. If we look back to even earlier age, we’ll find that people had to use manual wiring. Such low level of technology determines that the network at that time can only be centralized. But the improvement of technology always leads to the new round of decentralization. The invention of the TCP/IP protocol gave an impetus to the arrival of the Internet era. As packet switching took the place of circuit switching, information could get around freely. Under such circumstances, it was simply impossible for one single company to monopolize the the resources of the entire network. It brought us the era of decentralization. Many portal sites and personal blogs came into being, and everyday there were newborn projects plunging into the great tide of the times. This state of decentralization lasted for a while, then new problems appeared — information was difficult to search Driven by this demand, search engines and super APPs became the new centers of the whole system. However, based on the data and portals that they had, these apps could collect more data. This is how centralization got to the era of cloud computing and big data. Just as the time when TCP/IP made the world decentralized. Today, the new technology of blockchain has once again led the world to an era when centralization gives its way to decentralization. Blockchain, Value Network and Consensus Many years ago, I had thought, “Why can’t I just put my money into a file folder, in which each file represents a certain value, and when I send someone else a file, I simply transfer my money to him?” It is a pity that this idea could not be achieved by traditional Internet. The traditional Internet is a net of information and can only transmit the copies of those information. However, value, is not easy to transmit. But the birth of blockchain has totally changed the game and made it possible for value to be transferred, just as information is transmitted. This is the magic and charm of blockchain. Transactions on the blockchain can only be generated by the user’s private key, and once they are recorded by the blockchain, they are impossibly to be changed. Based on the consensus of certain mathematical principles, people can trade with everyone without trusting them. Where there is consensus, there is possibility of cooperation. All the wars and tragedies in human history are nothing but the result of the failed consensus. After the financial tsunami in 2008, almost at the same time, two people thought of a solution to all trust problems in the world. l A Chinese and a Japanese l Ge You and his invention, the conflict resolution terminal l Satoshi Nakamoto and his invention, blockchain I have explained to others what blockchain is for a million times —
It’s a distributive ledger.
It’s a decentralized application.
It’s a consensus platform.
It’s token economy.
I was totally enjoying my explanation, and the listeners were always like “What on earth are you talking about? Can you stop speaking Greek?” Let’s watch an interesting video first. it’s called “Ge You and his conflict resolution terminal”. After that I’ll explain what blockchain actually is. URL: https://v.qq.com/x/page/e133670fxux.html Ge You is a famous Chinese comedian actor, and I mention him here just for fun. In this movie, his conflict resolution terminal only has two nodes, and simply by this, he defrauds another man to bankruptcy. We can just give it a laugh. We can understand blockchain in this way: it is a conflict resolution terminal that countless people can participate at the same time. It can seal all the transaction contracts collectively, and no sealed participants can withdraw their transactions. One particular feature about the seal is that it’s a very complex paging seal, so that no one can change the data in it. Using his knowledge in cryptography and POW algorithm, Nakamoto really implemented such a conflict resolution terminal. The world’s top scientists and mathematicians have verified the solidity of this theory, and after nearly ten years of running tests, nothing wrong has ever happened. And its value has increased by millions of times. Well, I also admire Mr.Ge and his efforts for world peace. The challenge brought by decentralization OK I’ll skip the chitchat and go back today’s theme, the challenge of decentralization. The challenge of technology development Change is the only constant in life. Technology is updated and renewed everyday, and so is the technology of decentralization. Because of its trustworthiness by nature, many systems that requires an intermediary to increase credibility are strongly impacted, such as banks, insurance industry, and lottery industry. Beside that, due to decentralization and anonymity, decentralization will impact existing industry rules in many gray dark-web trades or in the field where the law is lagging. From the perspective of security, any problems caused by the high centralization can have great social consequences.These days, Facebook is facing a 2-trillion-dollar fine for its data breach, which is a wake-up call for everyone. As for China, let’s just imagine how our life will be impacted if Tencent or Alibaba or any other Internet industry giants go wrong. With the commercialization of 5G technology and the explosive growth of IOT devices, the Internet traffic has shown an exponential increase. The asynchronous growth of the terminal devices and the server is a bottleneck that all centralized processing systems will eventually face. The challenge of awareness. We can catch up when our technology is left behind, but we will forever be stuck in the past if our mind is left behind. Many of us have a belief that the society in which we are living, was, should be, and always will be what it is now. It’s not true. The money you are using is not actually your own money. The money we use today has not always been the same. In fact, it is only a few decades old. Before the Bretton Woods system collapsed, it required equivalent value of gold as the credit guarantee to issue currency. And nowadays, we always see news like the following: 1）The U.S. national debt has exceeded 20 trillion U.S dollars. 2）Xiong’an New Area received 100 billion yuan of credit. 3）China Merchants Bank grants 4 billion yuan of credit to Anbang Insurance Group 4）Anbang Insurance Group granted 10 billion yuan of credit to Guangyuan If you can understand that national debt and credit are the same as direct currency printing, you can understand that the money you use is actually not your own money. Blockchain is a bubble. So is the very essence of currency itself. The reason why the release of TOKEN is so popular is that people for the first time actually realize that the essence of currency is credit. Credit, however can be created by media packaging and celebrity platform. And TOKEN is human’s first try to issue currency by blockchain. In the past, it took real guts to do such things. People who can understand it, will be zealous for it. People who don’t, call it fraud. Companies, have not always been like their current form. Actually, in the future, they might even disappear. Economic rules tell us that the transaction cost is the reason why company exists. A company will eventually grow to a state in which the company’s transaction costs and management costs are in balance. After that, the expansion of the company will lead to the increase in management costs. However, in the future blockchain world, the transaction of costs will inevitably converge to zero. Can companies still find their reasons to exist at that time? It’s not a long time since the first company came into being. So I would like to say that, the demise of the form of companies will not be far in the future. In terms of market value, bitcoin market value is over $190 billion, exceeding Goldman Sachs and Morgan Stanley, as well as Boeing. In terms of trading volume, some bitcoin companies such as Binance, OKEX and Huobi have almost reached the scale of the China A shares. And here comes DAO, Distributed Autonomous Organization. In the future, more and more companies will be community-oriented on the base of blockchain. Also, there will be more start-up companies choosing to finance by blockchain and operate as a community directly. Different people will have different feelings and understandings even when watching the same TV series. I watched a Chinese TV series called “Nothing Gold Can Stay”. It led me to think that, in the era of emerging capitalism, how greatly the traditional family business was impacted by the new production relations of the companies. The protagonist Zhou Ying, richest women in her province, failed not because she did not do well, but because the backward production methods dragged her down to the inevitable tragedy. Similarly, in the future, it’s not because that you are not good enough, nor your company is not good enough, but because more and more companies change their patterns and choose a decentralized and community-based mode. Challenge of the society The law always lags. Code is the (new) law. The laws in almost in every country stipulate that users’ data on the Internet only belongs to the users themselves. Companies like Huawei and WeChat also claim that the data belongs to the users. But they know clearly that the data belongs to whoever has access to it. Facebook, as well, claims that they will protect the user’s data. However, things turns out that they sell the data to whoever pay them. All software has user authorization and agreement terms, but who will actually read it? What’s the point of reading? Since the law is merely a useless ceremony thing. There are hundreds of laws about company governance and financing, but how does it do with decentralized communities? The law stipulates that whoever commits a fraud over a certain amount of money will be put into jail. But in reality, there are people who just defraud billions of dollars by using the blockchain, and the law can do nothing about it. The country is also a form of relation of production Chinese students have learned about the relations of production since primary school. I’m not very good at it, so I won’t dig too deep. Today, we are living in a centralized society, working in a centralized company, getting paid with the temporary coinage issued by the centralized system and imagining the challenges that decentralization will bring to our lives. Of course, our biggest goal is to make a better and fairer society by blockchain, where everyone will have more new opportunities. In the end, I’d like to end up my speaking with a song. It’s called “ Song of Blockchain”.

The Bitcoin blockchain is a distributed public ledger that records network transaction formation by the chain of blocks. These blocks link together using block hash where the connection goes up to genesis block. There are network nodes( computers) spread all over the world and these nodes maintain the network. These blocks contain multiple transactions after mined that block eventually added ... What is Bitcoin Summary. Bitcoin is the first decentralized digital currency. All Bitcoin transactions are documented on a virtual ledger called the blockchain, which is accessible for everyone to see.Bitcoin gives you complete control over your money, unlike other assets you own which are regulated by banks and governments. My updated review of the Binance Bitcoin exchange will cover everything you need to know for 2018. Don’t trade before reading. Binance has taken the world by storm to become the leading exchange. Rare and high-potential altcoins, unique Maserati giveaways, and bargain basement fees have driven its rise from 0 to market leader in just 6 months. It even signed up 240,000 new users in just one ... The Binance Smart Chain will be run by 21 validators, similar to EOS and Tron, with a proof of staked authority (PoSA) consensus mechanism. Honestly, it doesn't really seem like they are even trying to compete against Ethereum. I am guessing they see this more like a Libra competitor. Blockchain is to Bitcoin what the internet is to email): Let’s say I have one bitcoin and I want to send it to you. Everybody who holds a copy of the Bitcoin ledger can see that I have one bitcoin and you have zero (but on the Bitcoin network our identities are relatively private). Binance Coin is now available to stake on the testnet of Binance Chain, the new blockchain that together with DEX aims to create an alternative marketplace for issuing, using, and exchanging digital assets in a decentralised manner. BNB has been the native token of the platform from the start, but introducing staking means that its holders will be able to earn annual interest. Initially, 3000 ...
