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.
A Beginners Guide to Bitcoin, Blockchain & Cryptocurrency
As cryptocurrency, and blockchain technology become more abundant throughout our society, it’s important to understand the inner workings of this technology, especially if you plan to use cryptocurrency as an investment vehicle. If you’re new to the crypto-sphere, learning about Bitcoin makes it much easier to understand other cryptocurrencies as many other altcoins' technologies are borrowed directly from Bitcoin. Bitcoin is one of those things that you look into only to discover you have more questions than answers, and right as you’re starting to wrap your head around the technology; you discover the fact that Bitcoin has six other variants (forks), the amount of politics at hand, or that there are over a thousand different cryptocurrencies just as complex if not even more complex than Bitcoin. We are currently in the infancy of blockchain technology and the effects of this technology will be as profound as the internet. This isn’t something that’s just going to fade away into history as you may have been led to believe. I believe this is something that will become an integral part of our society, eventually embedded within our technology. If you’re a crypto-newbie, be glad that you're relatively early to the industry. I hope this post will put you on the fast-track to understanding Bitcoin, blockchain, and how a large percentage of cryptocurrencies work.
Altcoin: Short for alternative coin. There are over 1,000 different cryptocurrencies. You’re probably most familiar with Bitcoin. Anything that isn’t Bitcoin is generally referred to as an altcoin. HODL: Misspelling of hold. Dank meme accidentally started by this dude. Hodlers are much more interested in long term gains rather than playing the risky game of trying to time the market. TO THE MOON: When a cryptocurrency’s price rapidly increases. A major price spike of over 1,000% can look like it’s blasting off to the moon. Just be sure you’re wearing your seatbelt when it comes crashing down. FUD: Fear. Uncertainty. Doubt. FOMO: Fear of missing out. Bull Run: Financial term used to describe a rising market. Bear Run: Financial term used to describe a falling market.
What Is Bitcoin?
Bitcoin (BTC) is a decentralized digital currency that uses cryptography to secure and ensure validity of transactions within the network. Hence the term crypto-currency. Decentralization is a key aspect of Bitcoin. There is no CEO of Bitcoin or central authoritative government in control of the currency. The currency is ran and operated by the people, for the people. One of the main development teams behind Bitcoin is blockstream. Bitcoin is a product of blockchain technology. Blockchain is what allows for the security and decentralization of Bitcoin. To understand Bitcoin and other cryptocurrencies, you must understand to some degree, blockchain. This can get extremely technical the further down the rabbit hole you go, and because this is technically a beginners guide, I’m going to try and simplify to the best of my ability and provide resources for further technical reading.
A Brief History
Bitcoin was created by Satoshi Nakamoto. The identity of Nakamoto is unknown. The idea of Bitcoin was first introduced in 2008 when Nakamoto released the Bitcoin white paper - Bitcoin: A Peer-to-Peer Electronic Cash System. Later, in January 2009, Nakamoto announced the Bitcoin software and the Bitcoin network officially began. I should also mention that the smallest unit of a Bitcoin is called a Satoshi. 1 BTC = 100,000,000 Satoshis. When purchasing Bitcoin, you don’t actually need to purchase an entire coin. Bitcoin is divisible, so you can purchase any amount greater than 1 Satoshi (0.00000001 BTC).
What Is Blockchain?
Blockchain is a distributed ledger, a distributed collection of accounts. What is being accounted for depends on the use-case of the blockchain itself. In the case of Bitcoin, what is being accounted for is financial transactions. The first block in a blockchain is referred to as the genesis block. A block is an aggregate of data. Blocks are also discovered through a process known as mining (more on this later). Each block is cryptographically signed by the previous block in the chain and visualizing this would look something akin to a chain of blocks, hence the term, blockchain. For more information regarding blockchain I’ve provided more resouces below:
Bitcoin mining is one solution to the double spend problem. Bitcoin mining is how transactions are placed into blocks and added onto the blockchain. This is done to ensure proof of work, where computational power is staked in order to solve what is essentially a puzzle. If you solve the puzzle correctly, you are rewarded Bitcoin in the form of transaction fees, and the predetermined block reward. The Bitcoin given during a block reward is also the only way new Bitcoin can be introduced into the economy. With a halving event occurring roughly every 4 years, it is estimated that the last Bitcoin block will be mined in the year 2,140. (See What is Block Reward below for more info). Mining is one of those aspects of Bitcoin that can get extremely technical and more complicated the further down the rabbit hole you go. An entire website could be created (and many have) dedicated solely to information regarding Bitcoin mining. The small paragraph above is meant to briefly expose you to the function of mining and the role it plays within the ecosystem. It doesn’t even scratch the surface regarding the topic.
How do you Purchase Bitcoin?
The most popular way to purchase Bitcoin through is through an online exchange where you trade fiat (your national currency) for Bitcoin. Popular exchanges include:
There’s tons of different exchanges. Just make sure you find one that supports your national currency.
Bitcoin and cryptocurrencies are EXTREMELY volatile. Swings of 30% or more within a few days is not unheard of. Understand that there is always inherent risks with any investment. Cryptocurrencies especially. Only invest what you’re willing to lose.
Transaction & Network Fees
Transacting on the Bitcoin network is not free. Every purchase or transfer of Bitcoin will cost X amount of BTC depending on how congested the network is. These fees are given to miners as apart of the block reward. Late 2017 when Bitcoin got up to $20,000USD, the average network fee was ~$50. Currently, at the time of writing this, the average network fee is $1.46. This data is available in real-time on BitInfoCharts.
In this new era of money, there is no central bank or government you can go to in need of assistance. This means the responsibility of your money falls 100% into your hands. That being said, the security regarding your cryptocurrency should be impeccable. The anonymity provided by cryptocurrencies alone makes you a valuable target to hackers and scammers. Below I’ve detailed out best practices regarding securing your cryptocurrency.
Two-Factor Authentication (2FA)
Two-factor authentication is a second way of authenticating your identity upon signing in to an account. Most cryptocurrency related software/websites will offer or require some form of 2FA. Upon creation of any crypto-related account find the Security section and enable 2FA.
The most basic form of 2FA which you are probably most familiar with. This form of authentication sends a text message to your smartphone with a special code that will allow access to your account upon entry. Note that this is not the safest form of 2FA as you may still be vulnerable to what is known as a SIM swap attack. SIM swapping is a social engineering method in which an attacker will call up your phone carrier, impersonating you, in attempt to re-activate your SIM card on his/her device. Once the attacker has access to your SIM card he/she now has access to your text messages which can then be used to access your online accounts. You can prevent this by using an authenticator such as Google Authenticator.
The use of an authenticator is the safest form of 2FA. An authenticator is installed on a seperate device and enabling it requires you input an ever changing six digit code in order to access your account. I recommend using Google Authenticator. If a website has the option to enable an authenticator, it will give you a QR code and secret key. Use Google Authenticator to scan the QR code. The secret key consists of a random string of numbers and letters. Write this down on a seperate sheet of paper and do not store it on a digital device. Once Google Authenticator has been enabled, every time you sign into your account, you will have to input a six-digit code that looks similar to this. If you happen to lose or damage the device you have Google Authenticator installed on, you will be locked out of your account UNLESS you have access to the secret key (which you should have written down).
A wallet is what you store Bitcoin and cryptocurrency on. I’ll provide resources on the different type of wallets later but I want to emphasize the use of a hardware wallet (aka cold storage). Hardware wallets are the safest way of storing cryptocurrency because it allows for your crypto to be kept offline in a physical device. After purchasing crypto via an exchange, I recommend transferring it to cold storage. The most popular hardware wallets include the Ledger Nano S, and Trezor. Hardware wallets come with a special key so that if it gets lost or damaged, you can recover your crypto. I recommend keeping your recovery key as well as any other sensitive information in a safety deposit box. I know this all may seem a bit manic, but it is important you take the necessary security precautions in order to ensure the safety & longevity of your cryptocurrency.
Technical Aspects of Bitcoin
Address: What you send Bitcoin to.
Wallet: Where you store your Bitcoin
Max Supply: 21 million
Block Time: ~10 minutes
Block Size: 1-2 MB
Block Reward: BTC reward received from mining.
What is a Bitcoin Address?
A Bitcoin address is what you send Bitcoin to. If you want to receive Bitcoin you’d give someone your Bitcoin address. Think of a Bitcoin address as an email address for money.
What is a Bitcoin Wallet?
As the title implies, a Bitcoin wallet is anything that can store Bitcoin. There are many different types of wallets including paper wallets, software wallets and hardware wallets. It is generally advised NOT to keep cryptocurrency on an exchange, as exchanges are prone to hacks (see Mt. Gox hack). My preferred method of storing cryptocurrency is using a hardware wallet such as the Ledger Nano S or Trezor. These allow you to keep your crypto offline in physical form and as a result, much more safe from hacks. Paper wallets also allow for this but have less functionality in my opinion. After I make crypto purchases, I transfer it to my Ledger Nano S and keep that in a safe at home. Hardware wallets also come with a special key so that if it gets lost or damaged, you can recover your crypto. I recommend keeping your recovery key in a safety deposit box.
What is Bitcoins Max Supply?
The max supply of Bitcoin is 21 million. The only way new Bitcoins can be introduced into the economy are through block rewards which are given after successfully mining a block (more on this later).
What is Bitcoins Block Time?
The average time in which blocks are created is called block time. For Bitcoin, the block time is ~10 minutes, meaning, 10 minutes is the minimum amount of time it will take for a Bitcoin transaction to be processed. Note that transactions on the Bitcoin network can take much longer depending on how congested the network is. Having to wait a few hours or even a few days in some instances for a transaction to clear is not unheard of. Other cryptocurrencies will have different block times. For example, Ethereum has a block time of ~15 seconds. For more information on how block time works, Prabath Siriwardena has a good block post on this subject which can be found here.
What is Bitcoins Block Size?
There is a limit to how large blocks can be. In the early days of Bitcoin, the block size was 36MB, but in 2010 this was reduced to 1 MB in order to prevent distributed denial of service attacks (DDoS), spam, and other malicious use on the blockchain. Nowadays, blocks are routinely in excess of 1MB, with the largest to date being somewhere around 2.1 MB. There is much debate amongst the community on whether or not to increase Bitcoin’s block size limit to account for ever-increasing network demand. A larger block size would allow for more transactions to be processed. The con argument to this is that decentralization would be at risk as mining would become more centralized. As a result of this debate, on August 1, 2017, Bitcoin underwent a hard-fork and Bitcoin Cash was created which has a block size limit of 8 MB. Note that these are two completely different blockchains and sending Bitcoin to a Bitcoin Cash wallet (or vice versa) will result in a failed transaction. Update: As of May 15th, 2018 Bitcoin Cash underwent another hard fork and the block size has increased to 32 MB. On the topic of Bitcoin vs Bitcoin Cash and which cryptocurrency is better, I’ll let you do your own research and make that decision for yourself. It is good to know that this is a debated topic within the community and example of the politics that manifest within the space. Now if you see community members arguing about this topic, you’ll at least have a bit of background to the issue.
What is Block Reward?
Block reward is the BTC you receive after discovering a block. Blocks are discovered through a process called mining. The only way new BTC can be added to the economy is through block rewards and the block reward is halved every 210,000 blocks (approximately every 4 years). Halving events are done to limit the supply of Bitcoin. At the inception of Bitcoin, the block reward was 50BTC. At the time of writing this, the block reward is 12.5BTC. Halving events will continue to occur until the amount of new Bitcoin introduced into the economy becomes less than 1 Satoshi. This is expected to happen around the year 2,140. All 21 million Bitcoins will have been mined. Once all Bitcoins have been mined, the block reward will only consist of transaction fees.
Any computer that connects to the Bitcoin network is called a node. Nodes that fully verify all of the rules of Bitcoin are called full nodes.
In other words, full nodes are what verify the Bitcoin blockchain and they play a crucial role in maintaining the decentralized network. Full nodes store the entirety of the blockchain and validate transactions. Anyone can participate in the Bitcoin network and run a full node. Bitcoin.org has information on how to set up a full node. Running a full node also gives you wallet capabilities and the ability to query the blockchain. For more information on Bitcoin nodes, see Andreas Antonopoulos’s Q&A on the role of nodes.
What is a Fork?
A fork is a divergence in a blockchain. Since Bitcoin is a peer-to-peer network, there’s an overall set of rules (protocol) in which participants within the network must abide by. These rules are put in place to form network consensus. Forks occur when implementations must be made to the blockchain or if there is disagreement amongst the network on how consensus should be achieved.
Soft Fork vs Hard Fork
The difference between soft and hard forks lies in compatibility. Soft forks are backwards compatible, hard forks are not. Think of soft forks as software upgrades to the blockchain, whereas hard forks are a software upgrade that warrant a completely new blockchain. During a soft fork, miners and nodes upgrade their software to support new consensus rules. Nodes that do not upgrade will still accept the new blockchain. Examples of Bitcoin soft forks include:
A hard fork can be thought of as the creation of a new blockchain that X percentage of the community decides to migrate too. During a hard fork, miners and nodes upgrade their software to support new consensus rules, Nodes that do not upgrade are invalid and cannot accept the new blockchain. Examples of Bitcoin hard forks include:
Note that these are completely different blockchains and independent from the Bitcoin blockchain. If you try to send Bitcoin to one of these blockchains, the transaction will fail.
A Case For Bitcoin in a World of Centralization
Our current financial system is centralized, which means the ledger(s) that operate within this centralized system are subjugated to control, manipulation, fraud, and many other negative aspects that come with this system. There are also pros that come with a centralized system, such as the ability to swiftly make decisions. However, at some point, the cons outweigh the pros, and change is needed. What makes Bitcoin so special as opposed to our current financial system is that Bitcoin allows for the decentralized transfer of money. Not one person owns the Bitcoin network, everybody does. Not one person controls Bitcoin, everybody does. A decentralized system in theory removes much of the baggage that comes with a centralized system. Not to say the Bitcoin network doesn’t have its problems (wink wink it does), and there’s much debate amongst the community as to how to go about solving these issues. But even tiny steps are significant steps in the world of blockchain, and I believe Bitcoin will ultimately help to democratize our financial system, whether or not you believe it is here to stay for good.
Well that was a lot of words… Anyways I hope this guide was beneficial, especially to you crypto newbies out there. You may have come into this realm not expecting there to be an abundance of information to learn about. I know I didn’t. Bitcoin is only the tip of the iceberg, but now that you have a fundamental understanding of Bitcoin, learning about other cryptocurrencies such as Litecoin, and Ethereum will come more naturally. Feel free to ask questions below! I’m sure either the community or myself would be happy to answer your questions. Thanks for reading!

Libra’s Threat To Central Banks Raises Questions About Its Launch According to AMBCrypto, Beatrice Weder di Mauro, President of the Centre for Economic Policy Research, is the latest think-tank professional to shed some light on Libra’s positive impact. In a recent interview with CNBC, di Mauro admitted that Libra may not receive a green light from lawmakers, adding that it had however managed to sow the seed for the introduction of another global digital currency. YI Huanhuan: There Will Be National-Level Digital Bank, Digital Asset Exchange, Digital Investment Bank And Digital Asset Management Services Beijing Financial Association Research Institute Dean Yi Huanhuan commented on this politburo study session. YI has made nine predictions on governments’ action and industrial trend based on XI’s remarks. 1. The Cyberspace Administration will likely oversee this [blockchain] field; 2. To establish a national association of blockchain; 3. A large number of blockchain pilots will appear first in the financial industry, and then in government administrations; 4. Chinese national digital currency will play an important role in the world; 5. There will be state level digital banks, digital asset exchanges, digital investment banks and digital asset management; 6. The global blockchain network standards are likely to be set by China; 7. China will generate a large number of world-class leaders, entrepreneurs, and scholars in blockchain; 8. The performance of blockchain will be improved significantly in the next three to five years; 9. Mathematics, cryptography, and computational theory will become the most popular subjects. Former Deputy Of BOC Governor: China has high blockchain visions, but should be careful with the trading risks and speculations Former Deputy Governor Of Bank Of China WANG Yongli shared his thought with CoinNess that China shows its ambition of establishing a leading global position in blockchain by researching and developing blockchain technology and applications. However, the blockchain technology is on an initial development stage. He urges investors to be careful with the trading risks and speculations as the definition of blockchain hasn’t been clarified, and there are existing issues like “decentralisation, security, high energy consumption” to be solved. Video Lessons Targeting Blockchain Technology Go Live On CCPPD’s Platform Following the news that XI Jinping, Chinese President and General Secretary of the Communist Party of China, addressed the importance of blockchain in making technological breakthroughs at the eighteenth group learning event organized by the Political Bureau of the Central Committee Oct 24, the Xuexi.cn platform led by the Publicity Department of the Central Committee of the Communist Party of China, or CCPPD, announced Oct 26 the launch of the video lessons targeting the blockchain technology. 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.

Thermodynamics & Silent Weapons for Secret Wars or Crypto Anarchy 101: Statists Failing & Anarchists Thriving
Crypto Anarchy 101: Statists Failing & Anarchists Thriving The black-market, the free-market, is what kept people alive throughout the worst of oppressions. The black market has been the art of surviving amidst all types of tyrannies and slaveries. The black market, aka System D, is something that everyone in the world will need to start getting comfortable with. CryptoAnarchy is the ultimate manifestation of complete market freedom, and it is here to stay. Libertarians are beginning to finally realize their incredible advantage within this new market environment. The unfortunate statist masses have been programmed to feel uncomfortable with the mere idea of complete market freedom. Keep in mind that as of 2009, half of the world’s workers- around 1.8 billion – were employed by System D. The black market is only expected to grow even more so with the incentive structures being built out in order to advance the technological advancements of cryptography. Humanity has never experienced a true free-market until now. For the first time in history one is beginning to take shape. The traditional business sector is beginning to realize that they are not even mentally equipped for the implications of having applied cryptography that is powered by market incentives. This is evident in their trite attempts at integrating these new technologies with traditional banking and financial systems. Their lack of creativity, and dependence on government, is a clear testament to how much they will be hurt in the coming future. Statists Double Down after Failure: Tether and Stablecoins Many within the crypto space have attempted to bridge the gap between legacy banking and cryptocurrencies. Amongst the various attempts at capitalizing with these new technologies, the idea of a stablecoin entered the space via Tether (USDT). A stable coin is a cryptocurrency that is pegged on a 1 to 1 ratio to the US dollar, or any other asset- like gold- or fiat. Tether operated as a stable coin pegged to the US dollar on a 1 to 1 ratio. The biggest attribute behind stablecoins resided in their ability to provide stability in an otherwise volatile market. For a long time many within the crypto space were curious about Tether’s means of operating with USD. Earlier this year TDV was the first entity to exclusively reported to its subscribers the origin of Tether’s “secret sauce;” fractional reserve banking. The laws of fractional reserve banking allowed the Noble Bank of Puerto Rico to provide Tether with the legal means of operating as a stable coin pegged to the US dollar. The Noble Bank recently went bankrupt due to being insolvent. Noble Bank was the bank of Bitfinex and Tether. As a result, Tether and Bitfinex ended their relationship with Noble Bank. It is important that you as a subscriber move your crypto out of Bitfinex. You should never keep your cryptoin exchanges. When you do this you don’t actually control the private keys of your coins. (If you are an active trader, please consider using Bisq. Bisq is an open source decentralized exchange that does not control your private keys while trading. It is the most Anarchist exchange in the market right now.) After losing its partnership with Noble Bank, Bitfinex began banking with HSBC. On October 15th, Bitfinex tweeted that their fiat deposit system was re-enabled. Overall, Bitfinex is still in the midst of reorganizing itself as an exchange with proper banking liquidity. For this reason we are of the opinion that it is best to stay away from Bitfinex until they are more solvent in their banking partnerships. Tether (USDT) on the other hand is suffering from a lack of proper banking structures. Binance paused all USDT withdrawals and KuCoin, the exchange, also paused USDT deposits and withdrawals. Tether is currently at around 2.1bn dollar market cap. Tether holders are having a difficult time cashing out of their Tether for USD. It is expected that unless Tether gets its banking situation sorted out, we will see movement out of Tether. This situation has caused the price of Tether to hit a low of $0.90 to the USD. As of writing this, Tether is trading at around $0.97 to the dollar. The situation for Tether is dire at the present moment. We expect to see many Tether holders drop their Tether for Bitcoin, or other more cryptographically secure cryptocurrencies. This will more than likely be one of the main strategies that will be implemented in order to cash out of Tether. This overall situation is once again showing us how unstable things are when dealing with fiat. We hope for the market to realize that there is more security in cryptocurrencies than there is in fiat backed stablecoins. Stablecoins will always have the instability of the fiat currencies that they are pegged to. The time will eventually come when people will realize that cryptocurrencies are a better store of value than stablecoins. In spite of all of the issues circulating Tether, statist entrepreneurs are doubling down on their desire for stablecoins. We are seeing the beginning of what we believe will be a trend in the upcoming future; that is, stable coins pegged to various countries’ fiat and assets like precious metals. The new USD stablecoins recently announced to the market are GeminiUSD, TrueUSD, and Paxos Standard. Volatility as a Sign of Life in the Market Contrary to the statist perception on volatility, one can also view volatility in crypto as proper to a market that is fully alive. Crypto, for the first time in history, freed the market from bankster manipulation. Arguably, volatility is to be expected in an unregulated free-market where everyone in the world is for the first time welcomed to participate. In comparison to the legacy financial system, crypto is fully alive while the former is handicapped by regulations, coercion, and disconnected from true free-market signals. That is, volatility signals of a free-market that breathes freely for the first time. Volatility is indicative of a market that is fully alive. The desire for individuals to attach crypto to the legacy financial system, under the pretense of “less volatility,” is indicative of individuals that will have a hard time operating outside the bounds of regulation and government coercion. As long as we have statists uncomfortable with Anarchy, we will have stablecoins pegged to fiat. Various Libertarian entrepreneurs are also beginning to dabble with the idea of a stablecoin that is pegged to precious metals. The challenge of these projects will be the same regulation that oversees fiat. Remember that the difference offered to the world by cryptocurrencies resides in crypto’s ability to operate freely within System D, without regulation. It is this new market, the true free-market, that for the first time is unstoppable. Bitfinex’s Effect on EOS Bitfinex is one of the entities that holds the greatest amount of votes for EOS Block Producers (BPs). For this and other reasons, we are currently expecting a shakeup of votes for selected top BPs. It is important that you remain attentive to the happenings within EOS and move your votes accordingly. We will soon be coming out with more details on our perceptions regarding various BPs. There are various discussions regarding BPs pending arbitration. This is a good thing. All shakeups lead us closer to more transparency and accountability. This should not directly affect the price of EOS, aside from what will result from the expected FUD of future BP shake-ups. The Resilience of CryptoAnarchy after Blockstream’s Fake Sidechain Amongst the various innovations within Bitcoin, sidechains have- for the past 5 years- existed as one of the holy grails of innovation. Blockstream, as a company, was put together to manifest sidechains. They sold us the concept of a sidechain as they were sourcing capital during their first rounds of investment; this was in October of 2014. Sidechains were supposed to be delivered by Blockstream as a way to make Bitcoin innovation competitive to that of altcoin innovation. Sidechains were supposed to be “the Altcoin killer.” After all of this time, Blockstream only delivered Liquid - which is not a sidechain- and called it a “sidechain.” That is, Liquid is not a sidechain when properly defined. Liquid is a multi-signature layer that allows for multiple exchanges to pool their money together to transfer funds amongst themselves. Liquid is not a true sidechain, it is more precisely a multi-signature wallet. Calling Liquid a “sidechain” was just a marketing scheme by Blockstream in order to impress the illusion that they had delivered what they had promised. They didn’t. Blockstream gave up in attempting to create a true sidechain and created a multi-signature wallet instead. Keep in mind that Liquid is a “private sidechain.” Note that a proper sidechain ought to be made with open-source innovation in mind. Many of us see the actions of Blockstream as a bait and switch marketing scheme. (For the rest of this article I will use the words “Drivechains” and “sidechains” interchangeably as synonyms. Drivechains are what sidechains originally were supposed to be- according to the original Blockstream Sidechain white paper. Blockstream’s bait and switch marketing scheme led to them calling “sidechain” a multisignature wallet that is not at all what they promoted on their white paper. Paul Sztorc, in an attempt to differentiate himself from the Blockstream perversion of the word “sidechains,” called his development of true sidechains “Drivechains.”) Drivechain Sidechains Paul Sztorc, the creator of decentralized prediction markets, was very much looking forward to Blockstream’s creation of sidechains. It was his hope that his decentralized prediction market would run as a Bitcoin sidechain. At about the end of 2015 Sztorc was done with BitcoinHiveMind, his decentralized predictions market (previously known as TruthCoin). After realizing that Blockstream was not going to deliver on sidechains, as promised, Sztorc felt he needed to build it himself. The creation of his Drivechains started off as a means to an end for Sztorc; he needed true Sidechains for his decentralized predictions market- so he build it himself. On September 24, 2018 Paul Sztorc announced the launch of the first Drivechain release. This release was accompanied with fervent followingof old-school Bitcoiners that immediately jumped into experimenting with Drivechains on the testnet known as “Testdrive.” The Drivechain protocol is an alternative to the sidechain project originally proposed by Blockstream. It is a simpler design that enables blockchain compatibility in which the system still utilizes the same 21 million bitcoin ruleset- the Nakamoto consensus. Drivechains are intended to allow for permissionless innovation without diluting or challenging the value of the main cryptocurrency. Contrary to other means of innovation within crypto, any innovation that comes from a Drivechain sidechain actually adds value to the Bitcoin protocol- for it does not dilute the main cryptocurrency. Satoshi vaguely discussed the importance of the ideas of sidechains and multi-blockchain connectivity on June 17, 2010. This creation, of providing varied market options, make infighting and political discourses regarding consensus upgrades now seem infantile. Drivechains will provide the market with ongoing competitive solutions for blockchain development. Investors will now be exposed to options that would otherwise have been shunned in a less free environment. The strategic advantage of Drivechain sidechains is that they will offer investors various options in the form of alternative chains. It is important to keep in mind that Drivechains are available for blockchains with the same UTXO set. That is, Drivechains are available for both BitcoinCore (BTC) and BitcoinCash (BCH). How Drivechains work Namecoin was the vision of early Bitcoin adopters of creating a DNS and identity infrastructure based on Bitcoin; that is, .bit DNS. This technology piggy backed on top of Bitcoin mining. That is, if you so chose you could merged-mined Namecoin alongside BTC or BCH. Namecoin can absorb hashrate from BTC or BCH without needing its own miners. Merge-mining with BTC or BCH is also the process of validating and safeguarding Drivechain sidechains. Unlike Namecoin, Drivechain sidechains don’t require miners to run special software. For Drivechain sidechains miners implement what is known as blind-merge-mining. In blind-merge-mining the nodes of the sidechain run the software, not the miners. This operates under the assumption that the nodes running the software also hold BTC or BCH. A payment fee is paid to miners to blind-merge-mine the sidechain, in a similar way that Namecoin merge-mining pays a fee. In this process, miners don’t have to run any software- they just passively make money for blind-merge-mining blocks with sidechains. The main difference with sidechains is that you are not mining another coin like Namecoin, but rather you are mining the same BTC or BCH in another sidechain when you do the blind-merge-mining. Miners don’t get paid with the sidechain, they receive payment from the mainchain that they already trust when they blind-merge-mine. Miners are also economically benefited by always getting paid in the superior coin that they are already intentionally mining; BTC or BCH. As BTC or BCH moves in and out from the mainchain to a sidechain, there might be claims of ownership that may cause disputes. Drivechain prevents this by emphasizing the superiority of the mainchain over sidechains. Sidechains have to report on exactly what it is doing- at all times- to the main chain. Whenever a sidechain wants to transfer money back to the mainchain it has to do it very slowly. This safeguards the network from theft. The slow movement of funds from the sidechain to the mainchain can be arbitrage by individuals who will be willing to purchase sidechain receipts for BTC or BCH coming from sidechains at a discount. People will also be able to do atomic swaps between chains in the near future. (Atomic swaps, or atomic cross chain trading, is the exchange of one cryptocurrency to another cryptocurrency, without the need of trusting a third-party). It is the intent of Drivechains to create the interaction of miners with sidechains as seamless as possible. However, it is still important to have guarantee that money ends up in the right place. This is the reason for the slow movement of funds from sidechains to the mainchain. The movement of a certain amount of transactions coming from a sidechain to the mainchain is batched up into one transaction with its own transaction ID. This transaction is frozen in place where miners and developers can examine it for at least a month (there are talks of even making this process longer between 3 to 6 months). During this time miners vote on whether to allow the payment to go through or not. Upon receiving enough upvotes, the batched up transactions are released unto the mainchain. The slowing down of movement of BTC or BCH from sidechains to mainchain decreases the threat of miners stealing BTC or BCH from a sidechain. The sidechains are always watching the mainchain, so they know to credit people immediately when the mainchain sends money to it. Sidechains also know when the miners have accepted the release of batched up locked funds that are released unto the mainchain. Once the sidechain receives notification of the miners acceptance of funds in the mainchain, the sidechain destroys the funds that were frozen awaiting miner upvotes. It is overall acknowledged that sidechains increase the value of BTC and BCH, which eventually make mining more profitable. It would be counterproductive for miners to attack and steal funds from sidechains. That is, miners acting maliciously decreases the value of their own equipment. In spite of this fact, it is good that Drivechains make it increasingly more difficult for theft to occur. Miners, through their voting process, also get to punish bad sidechain actors. Any malicious sidechain will be cleaned out by miners. This is the opposite of the Ethereum model where anyone can code anything into the Ethereum blockchain, to the point that it could become a detriment to the Ethereum mainchain itself. That is, anyone can create a new ERC20 or ERC721 token without any vetting from the network. Coins are moved from the mainchain to the sidechain by means of sending coins to an address that represents the sending of funds from the mainchain to the sidechain. Anyone running the given sidechain software will recognize that funds were sent to the sidechain- this will automatically credit the person with the same amount of BTC or BCH on the sidechain. Also, the sidechain is programmed to recognize the reception of funds unto the mainchain address from where it will automatically credit the user the same amount of BTC or BCH unto a sidechain wallet. People on the mainchain don’t have to know anything about this particular address. As far as they know, it is just another address. Embrace the Spontaneous Order of Market Anarchy It is important that people within BTC and BCH take on a more Hayekian approach to entrepreneurship. Many within crypto are uncomfortable with the mere notion of spontaneous order. It is important that we as Ancaps lead the way in motivating people to experiment with their entrepreneurship. In the past few years, the desire of individuals to covet the development of crypto has become more apparent. These people need to be ignored. No one is the leader of Bitcoin or crypto development. The best innovators within crypto are those that create tools that empower other entrepreneurs to create more options. It is this spontaneous order that we should welcome and promote at all times. Many within BTC and BCH will not accept or feel comfortable with the radical spontaneous order enabled by Drivechains. This is good reasonto brush up on your Austrian Economics in order to properly confront minds that are fearful of human freedom. The Ancap entrepreneurs who are most comfortable with spontaneous order will be the same ones who will produce the greatest amount of value. The development of CryptoAnarchy is guided by the science of praxeology and Austrian Economics. Drivechains are testament to the augmentation of our libertarian order are necessary for CryptoAnarchy to thrive. Drivechains and Investment Strategy The philosophical and economic advantage of sidechain innovation is that it enables the development of BTC and BCH with an investor-centric intention. It is the market’s investment that now decides the best means for scaling and development. Politics and propaganda take an almost insignificant backseat to that of market forces. The technology is now readily available for investors to test drive with their BTC or BCH on any given proposed sidechain. That is, you actually get to experience the value, or lack of value of a new innovation without jeopardizing your position as an investor. All investment decisions are about strategy. Sidechains empower the investor’s strategy by allowing the investor to survey all of the possible value propositions of his/her original investment without having to incur any actual costs. In a similar way, sidechains also provide developers with quick market feedback on the aspects of development that are most favored by the market. Drivechains are a pivotal step in maturing the crypto space into becoming more conscientious in considering the investment strategy of those buying the coins. It is important for innovators to start taking the investor’s strategy into account. Drivechains force developers to consider what is best for the investor, not just what is desired by a given team of developers. Here we have not only a better proposition for investors, but also an incentive for developers to use Drivechains in future crypto experimentation. When experimenting with an altcoin, the measure of success is contingent on this new altcoin gathering a new pool of investors to literally buy into the project. With a sidechain you are already dealing with a more seasoned group of investors that will provide you with more accurate market feedback, being that their investment is now fortified by all other sidechain experimentations that they have already tested at no cost. Altcoins will soon no longer be the locus of innovation within crypto. All future innovation will be offered the option to experiment within BTC or BCH via sidechains. Keep in mind that all previous innovations, already tested in the market by successful altcoins, are now easily adopted by BTC or BCH. It is also important to note that creative experimentation on sidechains do not at all jeopardize the mainnets of BTC or BCH. On the contrary, sidechains will make BTC and BCH much more valuable. When the Drivechain craze begins we will see a BTC and BCH bull run. Don’t be surprised if sidechains are the main reason for the next all time highs. Statists Failing & Anarchists Thriving It is important that we understand that the legacy banking system is completely dead. They are barely adopting simulations of cryptocurrencies unto their banking structures to stay alive. Stablecoins are a manifestation of this bankster angst to remain current. True market innovation is found in the embrace of Market Anarchy. CryptoAnarchy is growing exponentially with tools that are beyond the reach of state megalomaniacs. Drivechains are an example of the CryptoAnarchist tools that will result in further anti-fragility of this new crypto free-market. Proper Austrian Economic incentive structures coupled with applied cryptography is our lethal weapon against nation states and central banks. Arguably, our Ancap philosophy is what guides applied cryptography in the market towards success. For this reason it is important that we keep revisiting the texts of Rothbard, Mises, Hayek, and Konkin throughout our crypto endeavors.

Cryptocurrency: Is It Still Alive or Dying? Part 2
Cryptocurrency: Is It Still Alive or Dying? Part 2. Political and Economic Trends in Favor of the Cryptocurrency Market Development In the first part of the story we showed that the cryptocurrency market crash in 2018 and the beginning of its recovery in 2019 fit well into the general patterns of the financial bubbles’ development, and also repeat pretty well the Bitcoin dynamics of 2014-2016. But besides the analogies with other bubbles, there are a lot of other arguments in favor of the global growth of the market, among which are the political and economic trends of the recent years. Relaxation of the Political Climate around the Cryptoassets The entire year of 2017 has witnessed heated discussions as to the legal status of the digital assets. One of the central events of the year was their legalization in Japan in April. Precisely this legalization, according to many, spurred a dramatic growth of the cryptocurrency market in May (especially, altcoins). But the majority of other countries during this period held more skeptical positions. The U.S. government on several occasions refused to register bitcoin-ETF - exchange-traded funds, the price of shares in which would repeat the price of BTC. The U.S. government also extremely tightened the conditions of the ICO procedure, while some countries, such as China and South Korea - have banned it completely. Certain countries, such as Indonesia and Salvador, have banned cryptocurrencies to the extent of criminal responsibility. A number of countries, including Russia, have adopted a cautious wait-and-see attitude, regularly promising to impose restrictions of varying severity, but not hurrying to sign it into law. A turning point on the way to the global recognition of the cryptocurrency was the beginning of trading the Bitcoin futures at the Chicago exchanges (CME) (the world’s largest stock exchange in terms of turnover) and CBOE in December of 2017. That is when the American government admitted openly that cryptocurrencies are now to be reckoned with. With the beginning of this trade, the powerful financial circles of the USA, whose opinion cannot be ignored by the political leadership, became interested in the development of the cryptocurrency market. Chicago Mercantile Exchange, CME – the world leader in terms of trade volume In 2018, the following paradox became obvious: even if over the longer term cryptocurrencies are dangerous for the modern political system (tied up in the central banks and the currency exchange regulation), the countries that will be the first to prohibit them will be most affected along with those countries that will simply overdo stirring up negative attitude. Those countries that will settle on legalization will benefit. The drain of brains and capitals will be directed to these countries from the more repressive or unpredictable countries. A typical example of that - Crypto Project GRAM of the Russian businessman Pavel Durov, whose ICO in 2018 reached a record amount, but it was carried out in USA, and not in the legislatively uncertain Russian Federation. The experience of the countries that have legalized the cryptocurrencies, proved successful both from the financial standpoint, and from the perspective of the international prestige. They proved themselves to be open to the progress and new freedoms. In addition to Japan, Switzerland is especially noteworthy here, because it legalized cryptocurrencies as early as in 2016, but the most brilliantly announced about itself in 2018, when its banks began to introduce cryptocurrency services one after another. Among the innovator banks there was even a Swiss subsidiary of the Russian Savings Bank (Sberbank). The very expression “Swiss bank” became a synonym of not only high reliability, but also innovation. A milestone event of 2018 was legalization of cryptocurrencies in Germany – the leading economy of the European Union. Rather liberal measures relative to the cryptocurrencies are being applied today in Czechia, Sweden, Canada, Denmark, Australia, Estonia, Norway, Finland, and a number of other countries. “Legalization parade” has shown: the politicians with repressive attitudes cannot count on the global ban of the cryptocurrencies (which seemed theoretically possible in 2016-2017). Economically developed countries made an obvious choice: “if you cannot stop the process – become its leader”. And precisely in these countries the maximum capitals are being circulated, and the market situation depends precisely on their business activity. Explosive Growth of the Retail Use of Cryptocurrencies Despite obvious popularization of cryptocurrencies, there is still a myth that they are purely investment and speculative instrument, which, even if used as a payment method – only in the dark net, and as a means of payment for illegal commodities. But this is not the case today. As far back as 2013-2015, legal services accepting bitcoin emerged, and in 2016-2018 their market has undergone explosive growth. The pioneers of the cryptocurrency market of goods and services in 2013, were, for example, Virgin Galactic – space tourism company, Victoria’s Secret lingerie company, Shopify - a supplier of software for the online stores. In 2014, the cryptocurrency was adopted by the Overstock online store, Expedia tourism service, Zynga – operator of the online games, the software monster Microsoft and many others. Some of these companies considerably went up due to the innovations: for example, the shares of Shopify and Overstock have increased in price several-fold since then. As of today, the cryptocurrency is accepted by hundreds of large companies and thousands of small ones, while the range of their products is approaching the one in a traditional economy. The most popular categories of the goods for the cryptocurrency in the large famous companies are tourism and air tickets (Expedia), software and games (Microsoft, Shopify, Zynga, Steam), clothing and other consumer goods (Victoria’s Secret, Overstock.com, Rakuten), as well as food products (Subway, KFC, Burger King – in Russia). As an example, Playboy erotic products, premium accounts of the 4chan.org and reddit.com forums, Bloomberg.com business news, automobiles in the Czech show room Alza and many other goods can be also purchased for cryptocurrency. A number of well-known companies, although they prefer traditional payments, nevertheless allow crypto payments through the intermediary services, such as gyft.com (trading with the card Gyft for BTC). For example, Ebay online store, Wallmart supermarket chain, Starbucks restaurants, Uber taxi service, etc. The turnover of gyft.com is evaluated in the amount of 25 million dollars with only 38 employees. Small start-up companies often use ready-made multicurrency gateways such as coinpayments.net. It supports dozens of currencies, and hosts about 400 companies. In addition to mainstream, it contains a lot of specialized commodities. For example, crypto-armory.com sells cartridges, francvila.com – Swiss watches, directvoltage.com - 3D-printers, electric motors, CNC machines, etc. Some new stores not only accept cryptocurrencies, but also purposely give up fiat currency. For example, crypto-armory.com, explaining their refusal from fiat currency, state both ideological, and narrow pragmatic reasons. In the opinion of the owners of the store, it is easier to accept cryptocurrency payments both technically and legally. Cartridges from the cryptocurrency store crypto-armory.com An important trend of 2017-2018, in addition to the general growth of the commodity market - re-orientation of the stores to the multi-currency payments. Whereas previously most of them accepted only BTC, now a sign of good manners is to accept also LTC, ETH, XMR and at least several more currencies. Thus, while the politicians were solving the problem in the manner “not possible to allow - disallow”, a vast market of commodities for cryptocurrency spontaneously emerged on the Internet. Some of its participants have multibillion capitalizations. This market is very international. The majority of commodities and services can be bought even from Russia and other countries, where cryptocurrency is not legal as an internal payment instrument, but is not prohibited as such. Today, it is hard to imagine a consumer good, which cannot be bought for cryptocurrency. The Latest Trend – Support of Cryptocurrencies by Smartphones The first smartphone with a cryptocurrency wallet was HYPERLINK "https://bitcryptonews.ru/blogs/sravnenie-blokchejn-smartfonov-exodus-1-i-finney"HTC Exodus 1, released in the autumn of 2018. Then, a crypto smartphone HYPERLINK emerged "https://bitcryptonews.ru/blogs/obzor-kriptosmartfona-finney"Finney. And in March of 2019, the baton was unexpectedly picked up by the smartphone from the major South Korean company, Samsung - Galaxy S10. And although Samsung refrained from the direct embedding of the cryptocurrency wallet into the standard supply set, a brand wallet of Samsung can be installed from the Galaxy Store. https://preview.redd.it/p8zc6dat0ay21.jpg?width=1280&format=pjpg&auto=webp&s=d7f173f7470107c2f4cc5868ed882089499b2a09 Galaxy S10 – the first smartphone from Samsung with cryptocurrency support On the part of crypto enthusiasts, there are a number of claims to Samsung initiative, among which – the lack of bitcoin support (BTC). At the moment, Samsung Blockchain Wallet supports only Ethereum (ETH) and ERC-20 standard currencies and tokens created on its basis: Basic Attention Token (BAT), Chainlink (LINK), BinanceCoin (BNB), True USD (TUSD), USD Coin (USDC), Paxos Standard (PAX) and others. Anyway, from a political and PR perspective, the emergence of Galaxy S10 is a great event. First of all, smartphone can attract to the cryptocurrency market new people who have greater confidence in the famous brand, than in the traditional bulky cryptocurrency wallets. Now, many people are frightened away from the cryptocurrencies only by technical difficulties, whereas smartphones on many occasions have proved their ability to promote to the masses those things, which previously seemed to be very complex. Secondly, this step of Samsung is a clear signal both to the domestic and foreign governments: big business is on the side of the new technologies. South Korea has a reputation of a country not very friendly to cryptocurrencies, however, its business giant publicly demonstrated another attitude. Thirdly, the initiative of Samsung with a high degree of probability will be emulated by other leading producers of communication devices. Thus, shortly after the release of Galaxy S10, there appeared a news that a cryptocurrency wallet will soon be available in iOS Opera Touch, which means that cryptocurrencies can be also stored in iPhone of Apple. All this creates excellent prerequisites both for the world legalization of the cryptocurrencies, and for the growth of the market due to the increase of the number of users. Conclusion Thus, despite the “roller coaster” of the cryptocurrency exchange rates, some fundamental processes have developed steadily in the same direction in the recent years: expansion of the commodity market for cryptocurrency, increase in the number of countries with a liberal attitude to cryptocurrencies, adoption of cryptocurrencies as a strategic technology by more and more industrial giants. The total number of individuals who tried to work with the cryptocurrencies grows steadily, while the new technological trends (in particular, crypto smartphones), can additionally accelerate this growth. The only thing that can seriously damage a cryptocurrency market is its global ban, but it seems to be unlikely. Right now there are about 40 million bitcoin wallets on earth. It is believed that on average their number is doubled annually, which means that within 5 years it can reach a billion. And if now a global ban on cryptocurrencies is unrealistic due to their profitability for the developed countries, by that time their prohibition will become impossible almost physically. In the first part of the story we had put forward the arguments as to why the investors need not fear the bubble of 2017-2018: in the end, the bubble showed not so much the riskiness of the crypto investments, but rather their long-term prospects. Today we described political and economic events, which have occurred in parallel “behind the scenes”, and in which there were no “drops” – only progressive development toward the construction of the crypto economy. And in the next, third part, we will try to describe in detail specific financial reasons of the collapse and recovery of the market in 2018-2019.

Today we described political and economic events, which have occurred in parallel “behind the scenes”, and in which there were no “drops” – only progressive development toward the construction of the crypto economy. And in the next, third part, we will try to describe in detail specific financial reasons of the collapse and recovery of the market in 2018-2019.
