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.
I’ve been researching privacy coins deeply and feel I’ve reached a sufficient findings to merit sharing my stance re SUMO.
By Taylor Margot. Everyone should read this! THE BASICS SUMOkoin is a fork of MONERO (XMR). XMR is a fork of Bytecoin. In my opinion, XMR is hands down the most undervalued coin in the top 15. Its hurdle is that people do not know how to price in privacy to the price of a coin yet. Once people figure out how to accurately assess the value privacy into the value of a coin, XMR, along with other privacy coins like SUMOkoin, will go parabolic. Let’s be clear about something. I am not here to argue SUMOkoin is superior to XMR. That’s not what this article is about and frankly is missing the point. I don’t find the SUMOkoin vs. XMR debate interesting. From where I stand, investing in SUMOkoin has nothing to do with SUMOkoin overtaking XMR or who has superior tech. If anything, I think the merits of XMR underline the value of SUMOkoin. What I do find interesting is return on investment (“ROI”). Imagine SUMO was an upcoming ICO. But you knew ahead of time that they had a proven product-market fit and an awesome, blue chip code base. That’s basically what you have in SUMO. Most good ICOs raise over 20mil (meaning their starting market cap is $20 mil) but after that, it’s a crapshoot. Investing in SUMO is akin to getting ICO prices but with the amount of information associated with more established coins. Let me make one more thing clear. Investing is all about information. Specifically it’s about the information imbalance between current value and the quality of your information. SUMO is highly imbalanced. The fact of the matter is that if you are interested in getting the vision and product/market fit of a $6 billion market cap coin for $20 mil, you should keep reading. If you are interested in arguing about XMR vs. SUMOkoin, I point you to this infographic Background I’m a corporate tech & IP lawyer in Silicon Valley. My practice focuses on venture capital (“VC)”) and mergers & acquisitions (“M&A”). Recently I have begun doing more IP strategy. Basically I spend all day every day reviewing cap tables, stock purchase agreements, merger agreements and patent portfolios. I’m also the CEO of a startup (Scry Chat) and have a team of three full-time engineers. I started using BTC in 2014 in conjunction with Silk Road and TOR. I recently had a minor conniption when I discovered how much BTC I handled in 2014. My 2017 has been good with IOTA at sub $0.30, POWR at $0.12, ENJIN at $0.02, REQ at $0.05, ENIGMA at $0.50, ITC (IoT Chain) and SUMO. My crypto investing philosophy is based on betting long odds. In the words of Warren Buffet, consolidate to get rich, diversify to stay rich. Or as I like to say, nobody ever got rich diversifying. That being said I STRONGLY recommend you have an IRA and/or 401(k) in place prior to venturing into crypto. But when it comes to crypto, I’d rather strike out dozens of times to have a chance at hitting a 100x home run. This approach is probably born out of working with VCs in Silicon Valley who do the same only with companies, not coins. I view myself as an aggressive VC in the cryptosphere. The Number 1 thing I’ve taken away from venture law is that it pays to get in EARLY. Did you know that the typical founder buys their shares for $0.00001 per share? So if a founder owns 5 million shares, they bought those shares for $50 total. The typical IPO goes out the door at $10-20 per share. My iPhone calculator says ERROR when it tries to divide $10/0.00001 because it runs out of screen real estate. At the time of this writing, SUMO has a Marketcap of $18 million. That is 3/10,000th or 1/3333th. Let that sink in for a minute. BCH is a fork of BTC and it has the fourth largest market cap of all cryptos. Given it’s market cap, I am positive SUMO is the best value proposition in the Privacy Coin arena at the time of this writing. * ROI MERITS OF SUMOkoin So what’s so good about SUMOkoin? Didn’t you say it was just a Monero knock-off? 1) Well, sort of. SUMO is based on CryptoNote and was conceived from a fork of Monero, with a little bit of extra privacy thrown in. It would not be wrong to think SUMO is to Litecoin as XMR is to Bitcoin. 2) Increased Privacy. Which brings us to point 2. SUMO is doing several things to increase privacy (see below). If Monero is the King of Privacy Coins, then SUMO is the Standard Bearer fighting on the front lines. Note: Monero does many of these too (though at the time of fork XMR could not). Don’t forget Monero is also 5.8 billion market cap to SUMO’s 18 million. a) RingCT. All transactions since genesis are RingCT (ring confidential transactions) and the minimum “mixin” transactions is 13 (12 plus the original transaction). This passes the threshold to statistically resist blockchain attacks. No transactions made on the SUMO blockchain can ever be traced to the actual participants. Nifty huh? Monero (3+1 mixins) is considering a community-wide fork to increase their minimum transactions to 6, 9, or 12. Not a bad market signal if you’re SUMOkoin eh? b) Sub-addresses. The wallet deploys disposable sub-addresses to conceal your real sumo wallet address even from senders (who typically would need to know your actual address to send currency). Monero also does this. 3) Fungibility aka “Digital Cash” aka Broad Use Case. “Fungibility” gets thrown about a bunch but basically it means ‘how close is this coin to cash in terms of usage?’ SUMO is one of a few cryptos that can boast true fungibility — it acts just like physical cash i.e. other people can never trace where the money came from or how many coins were transferred. MONERO will never be able to boast this because it did not start as fungible. 4) Mining Made Easy Mode. Seeing as SUMO was a fork, and not an ICO, they didn’t have to rewrite the wheel. Instead they focused on product by putting together solid fundamentals like a great wallet and a dedicated mining app. Basically anyone can mine with the most intuitive GUI mining app out there. Google “Sumo Easy Miner” – run and mine. 5) Intuitive and Secure Wallet. This shouldn’t come as a surprise, yet in this day and age, apparently it is not a prereq. They have a GUI wallet plus those unlimited sub-addresses I mentioned above. Here’s the github if you’d like to review: https://github.com/sumoprojects/SumoGUIWallet The wallet really is one of the best I have seen (ENJIN’s will be better). Clear, intuitive, idiot proof (as possible). 6) Decentralization. SUMO is botnet-proof, and therefore botnet mining resistant. When a botnet joins a mining pool, it adjusts the mining difficulty, thereby balancing the difficulty level of mining. 7) Coin Emission Scheme. SUMO’s block reward changes every 6-months as the following “Camel” distribution schema (inspired by real-world mining production like of crude oil, coal, etc. that is often slow at first, then accelerated in before decline and depletion). MONERO lacks this schema and it is significant. Camel ensures that Sumokoin won’t be a short-lived phenomena. Specifically, since Sumo is proof-of-work, not all SUMO can be mined. If it were all mined, miners would no longer be properly incentivized to contribute to the network (unless transaction fees were raised, which is how Bitcoin plans on handling when all 21 million coins have been mined, which will go poorly given that people already complain about fees). A good emission scheme is vital to viability. Compare Camel and Monero’s scheme if you must: https://github.com/sumoprojects/sumokoin/blob/mastescripts/sumokoin_camel_emission_cal.cpp vs. https://monero.stackexchange.com/questions/242/how-was-the-monero-emission-curve-chosen/247. 8) Dev Team // Locked Coins // Future Development Funds. There are lots of things that make this coin a ‘go.’ but perhaps the most overlooked in crypto is that the devs have delivered ahead of schedule. If you’re an engineer or have managed CS projects, you know how difficult hitting projected deadlines can be. These guys update github very frequently and there is a high degree of visibility. The devs have also time-locked their pre-mine in a publicly view-able wallet for years so they aren’t bailing out with a pump and dump. The dev team is based in Japan. 9) Broad Appeal. If marketed properly, SUMO has the ability to appeal to older individuals venturing into crypto due to the fungibility / similarities to cash. This is not different than XMR, and I expect it will be exploited in 2018 by all privacy coins. It could breed familiarity with new money, and new money is the future of crypto. 10) Absent from Major Exchanges. Thank god. ALL of my best investments have happened off Binance, Bittrex, Polo, GDAX, etc. Why? Because by the time a coin hits a major exchange you’re already too late. Your TOI is fucked. You’re no longer a savant. SUMO is on Cryptopia, the best jenky exchange. 11) Marketing. Which brings me to my final point – and it happens to be a weakness. SUMO has not focused on marketing. They’ve instead gathered together tech speaks for itself (or rather doesn’t). So what SUMO needs a community effort to distribute facts about SUMO’s value prop to the masses. A good example is Vert Coin. Their team is very good at disseminating information. I’m not talking about hyping a coin; I’m talking about how effectively can you spread facts about your product to the masses. To get mainstream SUMO needs something like this VertCoin post: https://np.reddit.com/vertcoin/comments/7ixkbf/vertbase_a_vertcoin_to_usd_exchange/ MARKET CAP DISCUSSION For a coin with using Monero’s tech, 20 million is minuscule. For any coin 20 mil is nothing. Some MC comparisons [as of Jan 2, 2017]:
SUMO: 18 million
ENJIN: 150 million (9x)
Enigma: 465 million (26x)
REQ: 500 million (28x)
POWR: 500 million (28x)
Monero: 5.8 billion (mental maths iz hard)
Let’s talk about market cap (“MC”) for a minute. It gets tossed around a lot but I don’t think people appreciate how important getting in as early as possible can be. Say you buy $1000 of SUMO at 20 mil MC. Things go well and 40 million new money gets poured into SUMO. Now the MC = 60 million. Your ROI is 200% (you invested $1,000 and now you have 3,000, netting 2,000). Now let’s says say you bought at 40 million instead of 20 million. $20 mill gets poured in until the MC again reaches 60 mil. Your ROI is 50% (you put in $1,000, you now have 1,500, netting 500). Remember: investing at 20 mil MC vs. 40 mil MC represents an EXTREMELY subtle shift in time of investment (“TOI”). But the difference in net profit is dramatic. the biggest factor is that your ROI multiplier is locked in at your TOI — look at the difference in the above example. 200% ROI vs. 50% ROI. That’s huge. But the difference was only 20 mil — that’s 12 hours in the crypto world. I strongly believe SUMO can and will 25x in Q1 2018 (400m MC) and 50x by Q4 2018 reach. There is ample room for a tricked out Monero clone at 1 bil MC. That’s 50x. Guess how many coins have 500 mil market caps? 58 as of this writing. 58! Have many of these coins with about ~500 mil MC have you heard of? MaidSafeCoin? Status? Decred? Veritaseum? DRAGONCHAIN ARE YOU KIDDING ME THE ROLE OF PRIVACY I want to close with a brief discussion of privacy as it relates to fundamental rights and as to crypto. 2018 will be remembered as the Year of Privacy Coins. Privacy has always been at the core of crypto. This is no coincidence. “Privacy” is the word we have attached to the concept of possessing the freedom to do as you please within the law without explaining yourself to the government or financial institution. Discussing privacy from a financial perspective is difficult because it has very deep political significance. But that is precisely why it is so valuable. Privacy is the right of billions of people not to be surveilled. We live in a world where every single transaction you do through the majority financial system is recorded, analyzed and sold — and yet where the money goes is completely opaque. Our transactions are visible from the top, but we can’t see up. Privacy coins turn that upside down. Privacy is a human right. It is the guarantor of American constitutional freedom. It is the cornerstone of freedoms of expression, association, political speech and all our other freedoms for that matter. And privacy coins are at the root of that freedom. What the internet did for freedom of information, privacy coins will do for freedom of financial transactions. POST SCRIPT: AN ENGINEER’S PERSPECTIVE Recently a well respected engineer reached out to me and had this to say about SUMO. I thought I’d share. "I’m messaging you because I came at this from a different perspective. For reference, I started investing in Sumo back when it was around $0.5 per coin. My background is in CS and Computer Engineering. I currently research in CS. When I was looking for a coin to invest in, I approached it in a completely different way from what you described in your post, I first made a list of coins with market caps < 20m, and then I removed all the coins that didn’t have active communities. Next, because of my background, I read through the code for each of the remaining coins, and picked the coins which had both frequent commits to GitHub (proving dev activity), and while more subjective, code that was well written. Sumo had both active devs, and (very) well written code. I could tell that the people behind this knew what they were doing, and so I invested. I say all of this, because I find it interesting how we seem to have very different strategies for selecting ‘winners’ but yet we both ended up finding Sumo." — Legal Disclaimer: THIS POST AND ANY SUBSEQUENT STATEMENTS BY THE AUTHOR DO NOT CONSTITUTE LEGAL OR FINANCIAL ADVICE AND IS NOT INTENDED TO BE LEGAL OR FINANCIAL ADVICE OR RELIED UPON.

The videos with a total of 25 lessons mainly include the preliminary introduction to the blockchain technology, the consensus agreement, Bitcoin, Ethereum and smart contracts, blockchain performance improvement, blockchain security, the basic knowledge of big data, in-depth analysis of blockchain instances, as well as the concrete programming code examples. The Bitcoin Financing Case Accepted By Chinese Court For The First Time A loan dispute caused by the Bitcoin pledge has been put on file in Wuchang District People’s Court, Hubei Province (lying in central China). According to the indictment, the defendant pledged Bitcoin to borrow money from the plaintiff to bet on the rise of the king coin. During the Bitcoin decline cycle in 2018, the plaintiff took measures to liquidate the position forcibly, but still suffered some losses. The defendant does not acknowledge the loan relationship, falling to a material breach. Lawyer SUN Jun from Shanghai SHENHAO Law firm indicated that the financial attribute of Bitcoin would be recognized for the first time in China. For New Cryptography Law, China Took A Big Step In Right Direction, CZ Comments ZHAO Changpeng, also known as CZ, founder of Binance, reposted an article released by CoinDesk and titled “China’s Congress Passes Cryptography Law, Effective Jan. 1, 2020.” Regarding the issue, ZHAO commented, “This is big! The country with the biggest population on Earth, and one of the highest GDP growth in recent years, just took a big step in the right direction. What is your country gonna do? Follow or get left behind?” Baidu Search Index For Blockchain Up By 894% In Past 7 Days Amid President XI Highlighting Blockchain Citing data by Baidu Search Index, in the past seven days, daily average searches for the word “Bitcoin” were 31,955, which was 108% more than that of the previous year and 60% more than that of the previous week; daily average searches for the word “blockchain” was 42,444, which was 349% more than that of the previous year and 894% more than that of the previous week.

From a world where political leanings used to be personal, massive public attention and media campaigns now reign supreme. One of the most interesting developments to come out of this change is the rise of political betting. As a way to show faith in certain parties or leaders, this form of betting has drawn in new crowds and given existing speculators yet another avenue in which to engage. Bitcoin’s Price Moves Sideways. Last week, altcoins enjoyed an eventful week following significant price rallies. However, the price of Bitcoin wasn’t seen either rising or falling. While many altcoins endured a rise in the price of almost 90 percent over the past week, Bitcoin witnessed a mere 1.5 percent increase in the last seven days. One other day, one other spat within the crypto area… The president of the Bitcoin Affiliation, the entity behind Bitcoin Satoshi Imaginative and prescient (BSV), has accused Binance of cherry selecting its relationships with the cryptocurrency mission after information got here out earlier this week that the exchange’s new mining pool was now the only greatest verifier on the BSV protocol. Binance Coin Up 20% on DeFi IEO Hype; Pullback Ahead? Binance’s native token BNB surged by more than 20 percent after its CEO Changpeng Zhao announced his plans to launch an in-house decentralized finance product. The BNB/USD exchange rate on Sunday established its quarter-to-date high at $22.94.
