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.
With the large number of new readers coming to this sub we need to make information easy to access so those readers can make informed decisions. We all know there is an unusually large amount of Fear, Uncertainty and Doubt (FUD) surrounding EOS. Frankly, when clear evidence is provided it’s not that difficult to see EOS for the extremely valuable project it is. This post hopes to begin to put an end to all the misinformation by doing the following:
Giving a clear and concise answer to the most frequently asked questions in regards to EOS.
Giving a more in-depth answer for those who want to read more.
Allowing readers to make informed decisions by making credible information easy to access.
As EOS climbs the ranks we need to recognise there are going to be a lot of skeptical readers coming over and posting their questions. Sometimes they will be irrational, hostile and often just looking for a reaction. We should make it our responsibility to welcome everyone and refrain from responding emotionally to provocative posts, instead providing factual and rational answers. I will add to this post as and when I can, if you have any ideas or spot any mistakes let me know and I'll get them fixed ASAP. Im planning to add a bit on the team, centralisation and DPOS, governance and EOS VC shortly but please let me hear your suggestions!
1. How do you registeclaim your EOS tokens before June 2018?
Select Metamask, MyEtherWallet, or Ethereum Wallet
Follow the guide.
Remember that the reason you need to register your Ethereum ERC-20 address is to include your EOS tokens in order for the balance of your EOS Tokens to be included in the Snapshot if a Snapshot is created, you must register your Ethereum address with an EOS public key. The EOS snapshot will take place prior to the 1 June 2018. After this point your ERC-20 EOS tokens will be frozen. And you will be issued EOS tokens on the EOS blockchain.
So PLEASE REGISTER your Ethereum address NOW, don't forget about it, or plan on doing it some time in the near future.
There are a lot of submissions about this in /eos, so rather than making a new one please reply to this thread with any questions you may have. Don't forget to join the EOS mailing list: https://eos.io/#subscribe and join the EOS community on your platform(s) of choice: Telegram, Discord and/or Facebook. And remember, if anyone instructs you to transfer ETH to an EOS contract address that doesn't match the address found on https://eos.io you are being scammed.
2. How will the token the ERC-20 EOS tokens be transferred to the native blockchain?
There isn't one! Read the long answer then read it again, registering your Ethereum wallet is mandatory!
Within 23 hours after the end of the final period on June 1, 2018 at 22:59:59 UTC, all EOS Tokens will become fixed (ie. frozen) and will become non-transferrable on the Ethereum blockchain. In order to ensure your tokens are transferred over to the native blockchain you must register your Ethereum address with an EOS public key, if you do not you will lose all your tokens! I am not going to link any tutorials as there are many that can be found by searching Google and YouTube. block.one is helping with the development of snapshot software that can be used to capture the EOS token balance and registered EOS public key of wallets on the Ethereum blockchain. It is then down to the community to create the snapshot. This snapshot can be used when generating a genesis block for a blockchain implementing eos.io software. block.one will not be launching EOS blockchains or operating any of their nodes.
Exchange Support Some exchanges have announced that they will support the token swap. Although using this method will undoubtedly be much simpler than registering the tokens yourself it also comes with its pitfalls.
It is highly likely there are going to be multiple networks running on the eos.io software that use the snapshot. It is highly unlikely that exchanges will support them all.
It is highly likely that exchanges will not support airdrops that use the snapshot.
Exchanges that have announced support for the token swap include:
EOS.IO software is aiming to provide a decentralized operating system which can support thousands of industrial scale DApps by enabling vertical and horizontal scaling.
EOS.IO is software that introduces a blockchain architecture designed to enable vertical and horizontal scaling of decentralized applications. This is achieved through an operating system-like construct upon which applications can be built. The software provides accounts, authentication, databases, asynchronous communication and the scheduling of applications across multiple CPU cores and/or clusters. The resulting technology is a blockchain architecture that has the potential to scale to millions of transactions per second, eliminates user fees and allows for quick and easy deployment of decentralized applications.

6. Which consensus mechanism does EOS use and what are Block Producers?
Delegated Proof of Stake (DPOS) with Byzantine Fault Tolerance. Block Producers (BPs) produce the blocks of the blockchain and are elected by token holders that vote for them. BPs will earn block rewards for their service, these block rewards come in the form of EOS tokens produced by token inflation.
“EOS.IO software utilizes the only known decentralized consensus algorithm proven capable of meeting the performance requirements of applications on the blockchain, Delegated Proof of Stake (DPOS). Under this algorithm, those who hold tokens on a blockchain adopting the EOS.IO software may select block producers through a continuous approval voting system. Anyone may choose to participate in block production and will be given an opportunity to produce blocks, provided they can persuade token holders to vote for them. The EOS.IO software enables blocks to be produced exactly every 0.5 second and exactly one producer is authorized to produce a block at any given point in time. If the block is not produced at the scheduled time, then the block for that time slot is skipped. When one or more blocks are skipped, there is a 0.5 or more second gap in the blockchain. Using the EOS.IO software, blocks are produced in rounds of 126 (6 blocks each, times 21 producers). At the start of each round 21 unique block producers are chosen by preference of votes cast by token holders. The selected producers are scheduled in an order agreed upon by 15 or more producers. Byzantine Fault Tolerance is added to traditional DPOS by allowing all producers to sign all blocks so long as no producer signs two blocks with the same timestamp or the same block height. Once 15 producers have signed a block the block is deemed irreversible. Any byzantine producer would have to generate cryptographic evidence of their treason by signing two blocks with the same timestamp or blockheight. Under this model a irreversible consensus should be reachable within 1 second."
7. How does the voting process work?
The voting process will begin once the Block Producer community releases a joint statement ensuring that it is safe to import private keys and vote. Broadly speaking there will be two methods of voting:
Command Line Interface (CLI) tools
EOS Canada has created eosc, a CLI tool that supports Block Producer voting. Other Block Producer candidates such as LibertyBlock are a releasing web portal that will be ready for main net launch. There will be many more options over the coming weeks, please make sure you are always using a service from a trusted entity. Remember: Do not import your private key until you have seen a joint statement released from at least five Block Producers that you trust which states when it is safe to do so. Ignoring this warning could result in tokens lost.
8. What makes EOS a good investment?
Team - EOS is spearheaded by the visionary that brought us the hugely successful Bitshares and Steem - arguably with two projects already under his belt there is no one more accomplished in the space.
Funding - EOS is one of the best funded projects in the space. The block.one team has committed $1B to investing in funds that grow the EOS echo system. EOS VC funds are managed by venture leaders distributed around the world to insure founders in all markets have the ability to work directly with local investors. Incentives such as the EOS hackathon are also in place with $1,500,000 USD in Prizes Across 4 Events.
Community Focus - The team is aware that the a projects success depends almost entirely on its adoption. For this reason there has been a huge push to develop a strong world wide community. There is already a surplus number of block producers that have registered their interest and started to ready themselves for the launch and incentives the EOS hackathon are being used to grow the community. A index of projects using EOS can be found at https://eosindex.io/posts.
Technical Advantages - See point 9!
9. What are the unique selling points of EOS?
Potential to scale to millions of transactions per second
This depends entirely on your definition of working product. If a fully featured developer release meets your definition then yes!. Otherwise the public release will be June 2018.
EOS differs from other projects in that it aims to deliver a fully featured version of the software on launch. The Dawn 3.0 RC1 feature complete pre-release became available on April 5th. This version has all the features of the final release that is due June 2018. Further development will involve preparing the final system contract which implements all of the staking, voting, and governance mechanics. The common notion that there is no viewable code published is wrong and the initial Dawn 1.0 release has been available from September 14th 2017.
11. EOS is an ERC-20 token, how can it possibly be a competitor to other platforms?
The ERC-20 token is used only for raising funds during the token distribution; all tokens will be transferred to the native blockchain once launched.
EOS team has clearly stated their reason for choosing the Ethereum network when they described the rationale behind the ICO model. Specifically, the ICO should be a fair and auditable process, with as little trust required as possible. If you believe that an ICO should be fair, auditable, and trustless, you have no choice but to use a decentralized smart contract blockchain to run the ICO, the largest, and by-far most popular of which is Ethereum. Since EOS is intended to be a major competitor for Ethereum, some have seen this as a hypocritical choice. - Stolen from trogdor on Steam (I couldn’t word it any better myself).
12. Why do the eos.io T&C’s say the ERC-20 token has no value?
The EOS T&C’s famously state:
"The EOS Tokens do not have any rights, uses, purpose, attributes, functionalities or features, express or implied, including, without limitation, any uses, purpose, attributes, functionalities or features on the EOS Platform."
This is legal wording to avoid all the legal complications in this emerging space, block.one do not want to find themselves in a lawsuit as we are seeing with an increasing amount of other ICOs. Most notably Tezos (links below).
This all comes down to legal issues. Anyone who’s been into crypto for 5 minuets knows that government bodies such as the Securities and Exchange Commission (SEC) are now paying attention to crypto in a big way. This legal wording is to avoid all the legal complications in this emerging space, block.one do not want to find themselves in a lawsuit as we are seeing with an increasing amount of other ICOs. Many token creators that launched ICOs are now in deep water for selling unregistered securities.
A filing from the Tezos lawsuit:
"In sum, Defendants capitalized on the recent enthusiasm for blockchain technology and cryptocurrencies to raise funds through the ICO, illegally sold unqualified and unregistered securities, used a Swiss-based entity in an unsuccessful attempt to evade U.S. securities laws, and are now admittedly engaged in the conversion, selling, and possible dissipation of the proceeds that they collected from the Class through their unregistered offering."
To ensure EOS tokens are not classed as a unregistered security block.one has made it clear that they are creating the EOS software only and won’t launching a public blockchain themselves. This task is left down to the community, or more precisely, the Block Producers (BPs). The following disclaimer is seen after posts from block.one:
"block.one is a software company and is producing the EOS.IO software as free, open source software. This software may enable those who deploy it to launch a blockchain or decentralized applications with the features described above. block.one will not be launching a public blockchain based on the EOS.IO software. It will be the sole responsibility of third parties and the community and those who wish to become block producers to implement the features and/or provide the services described above as they see fit. block.one does not guarantee that anyone will implement such features or provide such services or that the EOS.IO software will be adopted and deployed in any way.”
It is expected that many blockchains using eos.io software will emerge. To ensure DAPPs are created on an ecosystem that aligns with the interests of block.one a $1bn fund will be has been created to incentivise projects to use this blockchain.
“A lot of token distributions only allow a small amount of people to participate. The EOS Token distribution structure was created to provide a sufficient period of time for people to participate if they so choose, as well as give people the opportunity to see the development of the EOS.IO Software prior to making a decision to purchase EOS Tokens.”
It is also worth noting that block.one had no knowledge how much the the token distribution would raise as it is determined by the free market and the length of the token distribution is coded into the Ethereum smart contract, which cannot be changed.
14. Where is the money going from the token distribution?
Funding for the project was raised before EOS was announced, the additional money raised from the token distribution is largely going to fund projects on EOS.
A large portion of the money raised is getting put back into the community to incentivise projects using eos.io software. block.one raised all the money they needed to develop the software before the ERC-20 tokens went on sale. There are some conspiracies that block.one are pumping the price of EOS using the funds raised. The good thing about blockchain is you can trace all the transactions, which show nothing of the sort. Not only this but the EOS team are going to have an independent audit after the funding is complete for piece of mind.
From eos.io FAQ:
“block.one intends to engage an independent third party auditor who will release an independent audit report providing further assurances that block.one has not purchased EOS Tokens during the EOS Token distribution period or traded EOS Tokens (including using proceeds from the EOS Token distribution for these purposes). This report will be made available to the public on the eos.io website.”
A more complete list of EOS projects can be found at eosindex.io.
16. Dan left his previous projects, will he leave EOS?
When EOS has been created Dan will move onto creating projects for EOS with block.one.
When a blockchain project has gained momentum and a strong community has formed the project takes on a life of its own and the communities often have ideas that differ from the creators. As we have seen with the Bitcoin and Ethereum hark forks you cant pivot a community too much in a different direction, especially if its changing the fundamentals of the blockchain. Instead of acting like a tyrant Dan has let the communities do what they want and gone a different way. Both the Bitshares and Steem were left in a great position and with Dans help turned out to be two of the most successful blockchain projects to date. Some would argue the most successful projects that are actually useable and have a real use case. What Dan does best is build the architecture and show whats possible. Anyone can then go on to do the upgrades. He is creating EOS to build his future projects upon it. He has stated he loves working at block.one with Brendan and the team and there is far too much momentum behind EOS for him to possibly leave.
No one could have better knowledge on this subject than our Block Producer candidates, I have chosen to look to EOS New York for this answer:
"DDoS'ing a block producing is not as simple as knowing their IP address and hitting "go". We have distributed systems engineers in each of our candidate groups that have worked to defend DDoS systems in their careers. Infrastructure can be built in a way to minimize the exposure of the Block Producing node itself and to prevent a DDoS attack. We haven't published our full architecture yet but let's take a look at fellow candidate EOSphere to see what we mean. As for the launch of the network, we are assuming there will be attacks on the network as we launch. It is being built into the network launch plans. I will reach out to our engineers to get a more detailed answer for you. What also must be considered is that there will be 121 total producing and non-producing nodes on the network. To DDoS all 121 which are located all around the world with different security configurations at the exact same time would be a monumental achievement."
18. If block producers can alter code how do we know they will not do so maliciously?
Block producers are voted in by stake holders.
Changes to the protocol, constitution or other updates are proposed to the community by block producers.
Changes takes 2 to 3 months due to the fact block producers must maintain 15/21 approval for a set amount of time while for changes to be processed.
To ensure bad actors can be identified and expelled the block.one backed community will not back an open-entry system built around anonymous participation.
For this question we must understand the following.
Governance and why it is used.
The process of upgrading the protocol, constitution & other updates.
Dan’s view on open-entry systems built around anonymous participation.
Governance Cryptography can only be used to prove logical consistency. It cannot be used to make subjective judgment calls, determine right or wrong, or even identify truth or falsehood (outside of consistency). We need humans to perform these tasks and therefore we need governance! Governance is the process by which people in a community:
Reach consensus on subjective matters of collective action that cannot be captured entirely by software algorithms;
Carry out the decisions they reach; and
Alter the governance rules themselves via Constitutional amendments.
Embedded into the EOS.IO software is the election of block producers. Before any change can be made to the blockchain these block producers must approve it. If the block producers refuse to make changes desired by the token holders then they can be voted out. If the block producers make changes without permission of the token holders then all other non-producing full-node validators (exchanges, etc) will reject the change.
Upgrade process The EOS.IO software defines the following process by which the protocol, as defined by the canonical source code and its constitution, can be updated:
Block producers propose a change to the constitution and obtains 15/21 approval.
Block producers maintain 15/21 approval of the new constitution for 30 consecutive days.
All users are required to indicate acceptance of the new constitution as a condition of future transactions being processed.
Block producers adopt changes to the source code to reflect the change in the constitution and propose it to the blockchain using the hash of the new constitution.
Block producers maintain 15/21 approval of the new code for 30 consecutive days.
Changes to the code take effect 7 days later, giving all non-producing full nodes 1 week to upgrade after ratification of the source code.
All nodes that do not upgrade to the new code shut down automatically.
By default, configuration of the EOS.IO software, the process of updating the blockchain to add new features takes 2 to 3 months, while updates to fix non-critical bugs that do not require changes to the constitution can take 1 to 2 months.
Open-entry systems built around anonymous participation To ensure bad actors can be identified and expelled the block.one backed community will not back an open-entry system built around anonymous participation. Dan's quote:
"The only way to maintain the integrity of a community is for the community to have control over its own composition. This means that open-entry systems built around anonymous participation will have no means expelling bad actors and will eventually succumb to profit-driven corruption. You cannot use stake as a proxy for goodness whether that stake is held in a bond or a shareholder’s vote. Goodness is subjective and it is up to each community to define what values they hold as good and to actively expel people they hold has bad. The community I want to participate in will expel the rent-seeking vote-buyers and reward those who use their elected broadcasting power for the benefit of all community members rather than special interest groups (such as vote-buyers). I have faith that such a community will be far more competitive in a market competition for mindshare than one that elects vote buyers."
19. What is the most secure way to generate EOS key pairs?
Block producer candidates EOS Cafe and EOS New York have come forward to help the community with this topic. The block producer candidate eosnewyork has kindly posted a tutorial on steemit detailing the steps that need to be taken to generate key pairs using the official code on the EOS.IO Github. The block producer candidate eoscafe has gone a step further and released an Offline EOS Key Generator application complete with GUI for Windows, Linux & Mac. Not only can this application generate key pairs but it can also validate key pairs and resolve public keys from private keys. This application has also been vouched for by EOS New York
Cardano (ADA) was created by a team led by Charles Haskinson, who previously worked on Ethereum, but left the number of cryptocurrency developers before the ICO. In 2014, he and Jeremy wood formed IOHK. In the same year, a group of Japanese investors signed a 6-year contract with this firm to create a blockchain project based on the use of algorithms for independent execution of exchange operations with different types of assets. https://preview.redd.it/2i65etfaxmt31.png?width=308&format=png&auto=webp&s=29c9fbda1552a59c33452e60afb1bd1b8d6c3d48 The platform was named after Gerolamo Cardano, an Italian mathematician, engineer, philosopher and astrologer. The Ada token was composed of 3 letters of the scientist's surname so that the name of the world's first female programmer-Ada Lovelace - turned out. The currency ICO was held in several stages in 2015-2017. as a result, $62 million was collected during operations only within the ADA Coin system. Until 2019, the developers plan to launch a number of decentralized applications and services for the implementation of smart contracts. In the beginning, the team warned that the low speed of operations (only 5-10 transactions per second) can affect the rate of cryptocurrency. Experts plan to increase the speed of transactions by introducing the system of bandwidth nodes, the Protocol of which will be written in the programming language Haskell. Also prevent the success of the project could reputation of the author of the idea of Charles Hoskinson, who left his previous job without explanation. But the cost of the coin was not affected by these factors, the prospects for the project are good. Cardano Presentation The success of the project is also facilitated by the fact that it is engaged in 3 institutions performing different functions:
IOHK is responsible for the construction of the siege system. This institution is engaged in the technical side of the platform, its improvement.
The Cardano Foundation is located in Switzerland. Responsible for the control of the organization and its development, standardization and protection of technologies.
Emurgo is based on the Isle of man. The organization was created to promote the company's products in the market.
The goal of the creators of the project is a sustainable system that is able to attract investment and thereby support itself.
MAIN FEATURES OF CARDANO COIN
Cardano (ADA) is a cryptocurrency whose task is to secure smart contracts between users on terms beneficial to both parties. Such principles of asset exchange will be the basis for further development of digital currencies. The Ada token has many pluses, but there are also minuses.
Democracy in the control of transactions and mining.
Scientific approach in the development of the mathematical block of the platform, allowing to have a good traffic generation.
High degree of protection against hacker attacks.
Protection of users from unscrupulous partners.
Using test software.
Incomplete platform management.
No protocols for long-term planning.
Insufficient control over the data provided by users.
HOW TO MINE CARDANO
The Cardano platform is based on the Proof of Stake algorithm. This means that the chances of a miner to create a block are directly proportional to the assets available to him, the results of work on solving a mathematical problem do not matter.
Advantages of Cardano mining:
No expensive equipment is required.
Don't need a lot of electricity.
WHERE AND HOW TO BUY CARDANO ADA CRYPTOCURRENCY
Cardano coins are traded in pairs with other cryptocurrencies on most exchanges (Finance, Bitrix, Http, Upbit, Bithumb, Cryptopia, etc.). There are exchangers (Prostocash, Xchange, 60 cek) and Exmo exchange, where you can buy Cardano cryptocurrency for rubles and other Fiat currency, after exchanging it for bitcoins or ethers. You can pay in exchangers via PayPal or Bank card. Purchase instructions ADA:
To buy in exchange for Bitcoin or Etherium.
Register on the exchange and install a wallet with Cardano support.
Exchange purchased bitcoins or ethers for Cardano.
Withdraw ADA to wallet.
Purchase on Binance Crypto exchanges provide the ability to store funds, but it is better to withdraw tokens to the wallet immediately after purchase. If this is not possible, you should take care of the security of your account. Asset storage is better not to trust little-known exchanges.
Until March 2018, the only e-wallet in which ADA could be stored was Daedalus. There are versions for Windows, Mac and Linux. The wallet is suitable for anonymous transactions. The Cardano team plans to issue a debit card that can be replenished through this e-wallet. Daedalus installation instructions:
Find the Get started tab and go to Deadalus wallet.
Click on Download, download the app.
Open the file, configure the installation settings.
https://preview.redd.it/tyomywqj2nt31.png?width=400&format=png&auto=webp&s=d0cf94f05c85c2205abde505831e5aeaca03dd8e In March, it became possible to store ADA tokens in the Centra wallet. This means that the currency can be withdrawn using the Centra card in 36 million terminals around the world. Web wallets are popular because of convenience. Many sites offer to download them to store ADA, but this should not be done, so as not to fall for the tricks of scammers. On the official website of the company there is no data on cooperation with owners of online wallets.
WHAT ARE THE PROSPECTS FOR THE ADA CRYPTOCURRENCY
Given the big plans of Cardano developers, the forecast for 2020 regarding this cryptocurrency is good. If the team implements its ideas to expand the use of coins, ADA may become popular in the market after a while, despite the fall in user confidence in cryptocurrencies. Road map of Cardano The author of the platform Hoskinson said that the work on scaling the data will not yield results until 2019. Developers want to introduce innovative technologies into their project, their creation and research takes a lot of time. By the end of the year, it is planned to standardize the protocols and improve the reliability of the system, but the achievement of these goals may be delayed due to the complexity of the ideas. At this stage of operation of the platform, information about the use of high technologies in support of Cardano's work is not proven. Cryptocurrency faces competition among firms providing such services. It interferes with its development. Specialists working on improving Litecoin and Dash use similar principles when conducting transactions. Ripple plans to become an element combining currencies recognized as official and digital assets, making it more attractive to investors. The exclusivity of the project is that its development is scientifically justified. But this is not a significant advantage, as most traders do not want to spend time figuring out the details of the technical side of the project, and are interested in its functionality. If the Cardano project team fulfills its plans by the end of the year, the prospect of this currency is quite good. The success of ADA depends on how convenient the token will be to use.
The biggest announcement of the month was the new kind of decentralized exchange proposed by @jy-p of Company 0. The Community Discussions section considers the stakeholders' response. dcrd: Peer management and connectivity improvements. Some work for improved sighash algo. A new optimization that gives 3-4x faster serving of headers, which is great for SPV. This was another step towards multipeer parallel downloads – check this issue for a clear overview of progress and planned work for next months (and some engineering delight). As usual, codebase cleanup, improvements to error handling, test infrastructure and test coverage. Decrediton: work towards watching only wallets, lots of bugfixes and visual design improvements. Preliminary work to integrate SPV has begun. Politeia is live on testnet! Useful links: announcement, introduction, command line voting example, example proposal with some votes, mini-guide how to compose a proposal. Trezor: Decred appeared in the firmware update and on Trezor website, currently for testnet only. Next steps are mainnet support and integration in wallets. For the progress of Decrediton support you can track this meta issue. dcrdata: Continued work on Insight API support, see this meta issue for progress overview. It is important for integrations due to its popularity. Ongoing work to add charts. A big database change to improve sorting on the Address page was merged and bumped version to 3.0. Work to visualize agenda voting continues. Ticket splitting: 11-way ticket split from last month has voted (transaction). Ethereum support in atomicswap is progressing and welcomes more eyeballs. decred.org: revamped Press page with dozens of added articles, and a shiny new Roadmap page. decredinfo.com: a new Decred dashboard by lte13. Reddit announcement here. Dev activity stats for June: 245 active PRs, 184 master commits, 25,973 added and 13,575 deleted lines spread across 8 repositories. Contributions came from 2 to 10 developers per repository. (chart)
Hashrate: growth continues, the month started at 15 and ended at 44 PH/s with some wild 30% swings on the way. The peak was 53.9 PH/s. F2Pool was the leader varying between 36% and 59% hashrate, followed by coinmine.pl holding between 18% and 29%. In response to concerns about its hashrate share, F2Pool made a statement that they will consider measures like rising the fees to prevent growing to 51%. Staking: 30-day average ticket price is 94.7 DCR (+3.4). The price was steadily rising from 90.7 to 95.8 peaking at 98.1. Locked DCR grew from 3.68 to 3.81 million DCR, the highest value was 3.83 million corresponding to 47.87% of supply (+0.7% from previous peak). Nodes: there are 240 public listening and 115 normal nodes per dcred.eu. Version distribution: 57% on v1.2.0 (+12%), 25% on v1.1.2 (-13%), 14% on v1.1.0 (-1%). Note: the reported count of non-listening nodes has dropped significantly due to data reset at decred.eu. It will take some time before the crawler collects more data. On top of that, there is no way to exactly count non-listening nodes. To illustrate, an alternative data source, charts.dcr.farm showed 690 reachable nodes on Jul 1. Extraordinary event: 247361 and 247362 were two nearly full blocks. Normally blocks are 10-20 KiB, but these blocks were 374 KiB (max is 384 KiB).
Update from Obelisk: shipping is expected in first half of July and there is non-zero chance to meet hashrate target. Another Chinese ASIC spotted on the web: Flying Fish D18 with 340 GH/s at 180 W costing 2,200 CNY (~340 USD). (asicok.com – translated, also on asicminervalue) dcrASIC team posted a farewell letter. Despite having an awesome 16 nm chip design, they decided to stop the project citing the saturated mining ecosystem and low profitability for their potential customers.
Changenow announced the option to buy DCR with fiat.
TokenPride: "We are seeking feedback on the general setup of our payment processor. We have tried to make it simple and user friendly. 10% of all purchases made in Decred will be donated to the Decred Development fund - and we will be releasing original Decred designs in the future".
BlueYard Capital announced investment in Decred and the intent to be long term supporters and to actively participate in the network's governance. In an overview post they stressed core values of the project:
There are a few other remarkable characteristics that are a testament to the DNA of the team behind Decred: there was no sale of DCR to investors, no venture funding, and no payment to exchanges to be listed – underscoring that the Decred team and contributors are all about doing the right thing for long term (as manifested in their constitution for the project). The most encouraging thing we can see is both the quality and quantity of high calibre developers flocking to the project, in addition to a vibrant community attaching their identity to the project.
The company will be hosting an event in Berlin, see Events below. Arbitrade is now mining Decred.
Campus Party in Brasilia, Brazil. @girino, @Rhama and @matheusd talked about Decred. Matheus was interviewed by a TV channel. Check this quick report about the event, click "Show newer" to continue reading. (photos: 123)
Blockchain Summit in London, UK. This was not a full blown presence with stand but rather investigation of opportunities by @kyle and @Ani. The resulting detailed report is a good example of a document advising to stakeholders whether it is worth spending project funds.
Meetup in Berlin, Germany on July 18. @jz will give a talk and Q&A about Decred and chat with Ele from @oscoin about incentivizing developers. Hosted by BlueYard Capital.
Hey guys! I'd like to share with you my latest adventure: Stakey Club, hosted at stakey.club, is a website dedicated to Decred. I posted a few articles in Brazilian Portuguese and in English. I also translated to Portuguese some posts from the Decred Blog. I hope you like it! (slack)
Decred Assembly - Ep20 - Governance: Driving the Future (youtube) @cburniske and @traceagain discuss the importance of governance protocols being foundational and problems with delegated proof of stake
"I think that developers in the future are going to base their decision on where to build on the basis of governance and community. And so I look for good governance mechanisms and strong communities in blockchains." (@decredproject)

What makes Decred different and better from other cryptocurrencies? (cxihub.com)
Community stats: Twitter followers 40,209 (+1,091), Reddit subscribers 8,410 (+243), Slack users 5,830 (+172), GitHub 392 stars and 918 forks of dcrd repository. An update on our communication systems:
Matrix chat logs are nowviewable on the web with the exception of some channels that are not bridged. The new web logs means our chats are now fully public and indexed by search engines.
Slack had an outage on Jun 27 that disturbed communications for a few hours, discussions continued on Decred's bridged platforms.
Jake Yocom-Piatt did an AMA on CryptoTechnology, a forum for serious crypto tech discussion. Some topics covered were Decred attack cost and resistance, voting policies, smart contracts, SPV security, DAO and DPoS. A new kind of DEX was the subject of an extensive discussion in #general, #random, #trading channels as well as Reddit. New channel #thedex was created and attracted more than 100 people. A frequent and fair question is how the DEX would benefit Decred. @lukebp has put it well:
Projects like these help Decred attract talent. Typically, the people that are the best at what they do aren’t driven solely by money. They want to work on interesting projects that they believe in with other talented individuals. Launching a DEX that has no trading fees, no requirement to buy a 3rd party token (including Decred), and that cuts out all middlemen is a clear demonstration of the ethos that Decred was founded on. It helps us get our name out there and attract the type of people that believe in the same mission that we do. (slack)
Another concern that it will slow down other projects was addressed by @davecgh:
The intent is for an external team to take up the mantle and build it, so it won't have any bearing on the current c0 roadmap. The important thing to keep in mind is that the goal of Decred is to have a bunch of independent teams on working on different things. (slack)
A chat about Decred fork resistance started on Twitter and continued in #trading. Community members continue to discuss the finer points of Decred's hybrid system, bringing new users up to speed and answering their questions. The key takeaway from this chat is that the Decred chain is impossible to advance without votes, and to get around that the forker needs to change the protocol in a way that would make it clearly not Decred. "Against community governance" article was discussed on Reddit and #governance. "The Downside of Democracy (and What it Means for Blockchain Governance)" was another article arguing against on-chain governance, discussed here. Reddit recap: mining rig shops discussion; how centralized is Politeia; controversial debate on photos of models that yielded useful discussion on our marketing approach; analysis of a drop in number of transactions; concerns regarding project bus factor, removing central authorities, advertising and full node count – received detailed responses; an argument by insette for maximizing aggregate tx fees; coordinating network upgrades; a new "Why Decred?" thread; a question about quantum resistance with a detailed answer and a recap of current status of quantum resistant algorithms. Chats recap: Programmatic Proof-of-Work (ProgPoW) discussion; possible hashrate of Blake-256 miners is at least ~30% higher than SHA-256d; how Decred is not vulnerable to SPV leaf/node attack.
DCR opened the month at ~$93, reached monthly high of $110, gradually dropped to the low of $58 and closed at $67. In BTC terms it was 0.0125 -> 0.0150 -> 0.0098 -> 0.0105. The downturn coincided with a global decline across the whole crypto market. In the middle of the month Decred was noticed to be #1 in onchainfx "% down from ATH" chart and on this chart by @CoinzTrader. Towards the end of the month it dropped to #3.
Please note: we will not accept any kind of payment to list an asset.
Bithumb got hacked with a $30 m loss. Zcash organized Zcon0, an event in Canada that focused on privacy tech and governance. An interesting insight from Keynote Panel on governance: "There is no such thing as on-chain governance". Microsoft acquired GitHub. There was some debate about whether it is a reason to look into alternative solutions like GitLab right now. It is always a good idea to have a local copy of Decred source code, just in case. Status update from @sumiflow on correcting DCR supply on various sites:
To begin with, none of the below sites were showing the correct supply or market cap for Decred but we've made some progress. coingecko.com, coinlib.io, cryptocompare.com, livecoinwatch.com, worldcoinindex.com - corrected! cryptoindex.co, onchainfx.com - awaiting fix coinmarketcap.com - refused to fix because devs have coins too?

This is the third issue of Decred Journal after April and May. Most information from third parties is relayed directly from source after a minimal sanity check. The authors of Decred Journal have no ability to verify all claims. Please beware of scams and do your own research. The new public Matrix logs look promising and we hope to transition from Slack links to Matrix links. In the meantime, the way to read Slack links is explained in the previous issue. As usual, any feedback is appreciated: please comment on Reddit, GitHub or #writers_room. Contributions are welcome too, anything from initial collection to final review to translations.

5 most promising Altcoins for long-term investments | Coinscapture
After the success of Bitcoin and the rise in the price of the first-ever cryptocurrency, many new coins were developed in cryptoworld. In simple words, any coin other than bitcoin is termed as “Altcoins”. These coins are created by tweaking the Bitcoin's or any other existing cryptocurrencies protocol. In the growing world of cryptocurrency, there are more than 3000 cryptocurrencies which came into existence and so it is a tough job to choose the right Altcoin to invest in it. Here are the 5 most promising Altcoins that can help you to narrow your search. Disclaimer: This guide should not be considered as financial advice. It is highly recommended to do appropriate market research before any investments.
After the successful launch of Bitcoin, Litecoin was the next one to enter the Cryptoworld in 2011. Charlie Lee - a computer scientist created Litecoin by making some technical changes in the bitcoin’s source-code and made it the fastest peer-to-peer currency that enabled instant, near-zero cost payments to anyone across the world. Also, litecoin has a total supply of 84 million with an average block mining time of 2.5 minutes.
Reasons why to choose Litecoin as a Long-Term Investment
Improved: Litecoin algorithm is generally easier to mine but difficult to crack The bitcoin mining is highly processed intensive requiring, application-specific integrated circuit devices with high processing capabilities, while Litecoin mining is memory-intensive requiring less cost-intensive graphics processing units (GPU).
Faster block-processing rate: The technical changes done on Bitcoin’s source-code allows Litecoin to processes a block at a much faster rate and giving out rewards to the miner faster in every 2.5 minutes as compared to Bitcoin which processes a block in every 10 minutes. Litecoin network have more capacity to handle the transactions than bitcoin's network
SegWit upgrade: Litecoin's SegWit upgrade boost the capacity of the number of transactions a block can hold in litecoin's blockchain, thereby speeding up the transaction settlement times and lowering transaction costs.
Higher trading volume: The trading of Litecoin has begun since 2011 and since then it was in the top 10 list of coins. The popularity of Litecoins is so much that you won't face any problem selling them in the future which brings less fear of having risk as compared to other new coins.
Ethereum is the second-largest digital currency introduces Vitalik Buterin in late 2015. It has been a popular choice in many industries as its cool feature named Smart Contracts helps developers to build decentralized applications (dApps) on top of its (i.e. Ethereum's) blockchain which helps to avoid fraud, downtime, and control or interference from a third party. Ethereum can also be used for banking and financial service contracts, ICOS, prediction markets, replacing escrow, identity management. The Enterprise Ethereum Alliance founded in 2017 has over 200 organizations that are testing on various versions of Ethereum's blockchain in different industries. Ethereum has a circulating supply of 106,376,346 ETH, the market capitalization of $26,307, 580,992 and faster transaction of 6 minutes as compared to Bitcoin.
Reasons why to choose Ethereum as a Long-Term Investment
Multi-purpose usage- Other than trading Ethereum can be used for ICOs, prediction markets, building tokens and many more ways that very few cryptocurrencies can do as good as Ethereum.
Safety: The apps built on Ethereum’s blockchain termed as dApps or decentralized apps are significantly safer and more resistant to hacking than the software you use now.
Smart contracts: The smart contract feature offers significant business benefits over more traditional conventional forms of cloud computing and transaction-clearing.
Initial Coin Offerings: Ethereum is used ICOs (Initial Coin Offerings) that means it acts as a launchpad for new tokens which thereby makes it a valuable platform and price will increase with its use.
Ripple is the hot choice in banking and financial institutions as it can be used as an intermediary for quick transaction-processing and settlement service; allowing to transact directly and instantly across national borders. XRP currently has a fast transaction processing time of about 4 seconds and a cheap transaction fee about $0.004 per transaction (which is less than half a cent). It has a circulating supply of 42,181,995,112 and a market capitalization of around 17 billion USD.
Reasons why to choose Ripple as a Long-Term Investment
Well distributed: Ripple is an open-source technology, built on the principles of blockchain with an increasing set of validators.
Highly Scalable: XRP has the potential to handle 1,500 transactions per second, 24x7, and can scale to deal with a similar throughput as Visa.
Highly Stable: The most stable record of Ripple makes it ready for institutional and enterprise use.
Global Bank partners: Ripple has partnered with over 100 banks like Bank of America, UBS, Standard Chartered, Barclays, JP Morgan, Santander, and American Express.
Stellar offers the fastest and the cheapest online payment and cross-border payment services as compared to the other large companies. Also, it does not use proof of work verification which is time and energy consuming which allows processing a transaction in approx 5 seconds. It has a market capitalization of $2,378,213,121 and a circulating supply of 19.331,689,641.
Reasons why to choose Stellar as a Long-Term Investment
Low-cost transactions: Stellar’s payment protocol prioritizes profit, the low transaction time and high operational efficiency translates to a lower cost of transactions.
Currency exchanger: Stellar’s platform also acts as a currency exchanger between government-backed currencies, such as dollars to euros.

StrataMiner is ready for download. Feature-packed software package for controlling and monitoring any number of rigs.
StrataMiner is now released for beta testing. Looking for a few brave miners. Go to strataminer.com to learn and install. I'll be answering any questions here today. For technical support, please email me at [email protected]. Tell me what operating system you're on in the email message. Features Windows and Linux - Made for both. Client and Control Center don't need to be on the same OS either. Profit Switching - Flip the switch and you'll always be mining the best currency for each device. Any pool - StrataMiner works with any pool using a standard stratum protocol. Web Portal - Control your rigs from anywhere on the planet with an internet connection. 24 coins and counting - AEON, Bitcoin Gold, Denarius, Ethereum, Ethereum Classic, GoByte, Groestlcoin, HUSH, Komodo, LOKI, Monacoin, Monero, MusicCoin, Pirl, Quantum Resistant Ledger, Ravencoin, Trezarcoin, Ubiq, Verge, Vertcoin, Vivo, ZCash, ZClassic, Zen. More coming. Exchange address generation - StrataMiner can generate deposit addresses on your Cryptopia and Bittrex accounts. Once your crypto hits your exchange, you can easily exchange for 100s of others. More exchanges coming soon. One-click updates - No installers required for updates of mining core software. Stay up-to-date through Control Center with a single click. Community features - With pool sharing enabled, you become part of a community working to ensure pools are always available and trustworthy. This service is part of StrataMiner's commitment to decentralized mining. Hashrate verification - StrataMiner's proprietary Adaptive Proxy technology enables auditing of pool communications to verify that hashrate reports match share submission statistics. In other words, StrataMiner makes sure everybody is being honest. Familiar miner cores - Ethminer, Claymore Miner, CCMiner, EWBF, XMR-Stak Automatic network configuration - The Control Center and Client know how to find each other. Turn them on and go. Email notifications - Requires Gmail. Receive an email if something's not right. The messaging is still a little rudimentary. Low fees - 0.5% for development. Miner cores and pools may have additional fees. Earnings tracking - Earnings estimations are tracked over time. Earnings are recorded in both USD and crypto. Market data - Up to date market information for each currency, including market capitalization, price, and 24-hour change. Open source software - The Control Center is open-source and written in Python 3. See pystrata on github if you're interested in fiddling with the code. What you get for your fee New miners and algorithms - New stable miners will be incorporated based on community desire. Strataminer tracks algorithm changes and blockchain forks for you, so you'll always have working software, if available. New coins - Many can be added within hours of receiving a request. No software updates required. New features - The feature set will be improved based on community feedback. This is only the beginning. Technical support - Development fees enable StrataMiner to respond to issues and fix bugs quickly and continuously. StrataMiner API - New coin data, new mining software, and some market data come from the StrataMiner API. An obvious drawback is that you'll need an address for each currency that you want to mine. If you have Cryptopia and Bittrex accounts, you can use auto-generation to make addresses for all but 4 of the supported currencies (XMR, AEON, LOKI, QRL). I'll work on integrating Binance, CoinExchange, and HitBTC next. The Coinomi mobile wallet can also get you 16 of the 24 supported currencies. You'll need pretty fresh drivers, partly for StrataMiner and partly for the miner cores, i.e. Ethminer, ... I actually expect to ease up on StrataMiner's driver requirements a little, but you'll still want to keep fresh drivers for the mining software updates, as they come. On request, I've lowered the driver requirements for StrataMiner itself, but if you don't have the newest drivers, you may not be able to use Ethminer. You can still use Claymore for Ethash though. Minimum drivers are now >= 385.54 on Windows, >= 384.81 on Linux. StrataMiner is not affiliated with or sponsored by any exchange, any pool, any other website, or any other software vendor.

What is Waltonchain?
The Waltonchain Foundation is building a cross-industry, cross-data sharing platform by integrating Blockchain with the Internet of Things through self-developed RFID Chips with intellectual property rights. The in-house developed Waltonchain RFID chips integrate a proprietary, genuine random number generator and an asymmetric encryption logic and hardware signature circuit, all of which are patent-protected. The combination of self-developed RFID chips and the Waltonchain blockchain will ultimately achieve the interconnection of all things and create a genuine, believable, traceable businessmodel with totally shared data and transparent information. Waltonchain will unfold a new era of the Value Internet of Things (VIoT).
The Waltonchain team has formulated a 4-phase development plan, starting from infrastructure platform establishment to gradually incorporating retail, logistics and product manufacturing, and to finally achieving the full coverage of the business ecosystem.
As for the phase 1.0 of the project, the team has developed the clothing system integration scheme based on RFID. The application scenarios at phase 1.0 will establish Golden demonstration template At phase 2.0, our RFID beacon chip will be massproduced and can be used in clothing, B2C retail and logistics. At phase 3.0, manufacturers will achieve traceable customization of intelligent packaging. At the project phase 4.0, with the upgrading and iteration of assets information collection hardware and improvement of blockchain data structure, all assets can be registered in Waltonchain in the future.
