Any accounting <em>is posted</em> entry is required to be write-only, with the database being set to ensure the read-only nature of posted entries. Accountants have used such a ledger format and posted journal entries using the same method for over 800 years now. Traditionally, accounting records would be maintained using a double-entry ledger written on paper. With a paper record, any alterations would require the creation of a completely new ledger with the new entry and all of the updated values, which was difficult to do in many cases, or an easily detected scenario where someone had intentionally changed values in the ledger, which would then require extensive changes throughout all of the journals.</p><p>Some things changed with the advent of computerised ledger systems. Accounting databases became easy to copy and easy to alter. Although high-end specialist accounting systems, including Oracle-based solutions, allow organisations to ensure that such scenarios are not possible, many fraudulent organisations have found simple ways of bypassing controls using technology. Bitcoin can solve all of the prevalent issues.</p><p>In a general-ledger system based on paper journals, a controller maintained access to a general ledger that summarised all of the specialised journals held by different clicks within an organisation. Where errors occurred, companies would need to rectify the errors and ensure that the accounting records were correct. As with Bitcoin, a paper-based journal was not updated by removing or reversing an entry, but by creating a new entry in the registry or journal, correcting the error that had occurred in the system. Such a change would be visible, and the errors would be available for auditors to review.</p><p>Journals present a chronological record of all transactions. The Bitcoin blockchain may be grouped following an initial transaction or unspent transaction output (UTXO), allowing each transaction to run in parallel and form some journal specific to a transaction type or source. The same method allows for the creation of sub ledgers by account and the creation of a private yet secure accounting platform, built on top of Bitcoin.</p><p>Bitcoin nodes (aka miners) maintain the ledger for a fee. They act as agents for the network, and follow and enforce a set of rules. Some people like to say that Bitcoin miners cannot alter the database. Whilst Bitcoin nodes do not delete entries, it is possible to append records and for honest miners to reassign records and registry entries. Note, Bitcoin is not encrypted but presents clear text, which means that alterations to the database structure are possible. An attacker who cannot make such a change would be rejected by SPV nodes on the network and present good evidence demonstrating the attack. Nodes are subject to legal actions, as are any exchanges where coins are sold. The myth that third parties cannot seize or freeze coins is not one that finds any ground in reality.</p><p>A false narrative that no third-party seizure was possible in Bitcoin developed following Silk Road. A widely distributed source of the fallacy stems from a poorly researched Stanford undergraduate project [1]:</p><blockquote>No Third-Party Seizure</blockquote><blockquote>Since there are multiple redundant copies of the transactions database, no one can seize bitcoins. The most someone can do is force the user, by other means, to send the the bitcoins to someone else. This means that governments can’t freeze someone’s wealth, and thus users of Bitcoins will have complete freedom to do anything they want with their money.</blockquote><p>Bitcoin does not stop your money from being seized. Bitcoin prevents dishonest third parties from cheating. Governments can easily place freezing orders against coins (bitcoin). Under proceeds of crime legislation, everything that a coin is mixed with will be tainted. In effect, if you put your money in a mixer, then it will be tainted money. Unless you return the tainted tokens that you have received, you will find that they can be taken from you. Bitcoin works using isolated UTXOs. As a result, somebody cannot send you tokens that are mixed with your own without your knowledge. When receiving bitcoin for payment, you can record the sale and the identity information of the person you have received the coins from. You can demonstrate that the sale and transfer of the bitcoin was done in good faith (<em>bona fide</em>) and <em>without knowledge</em> (of a recent illicit activity).</p><p>When I implemented the alert key into Bitcoin, I created a mechanism that allowed people to simply report stolen bitcoin, and other proceeds of crime. It greatly enhanced the ability of Bitcoin to act within a legal framework and protect the users of the system. Right now, the removal of the mechanism of the alert key has increased the difficulty and amount of research required by individuals to find tainted bitcoin. Having said so, all the sources of tainted bitcoin that you should be aware of are available online, in different locations. The cost without the alert key is just far greater.</p><h3>The Alert Key</h3><p>Removing the alert key does not remove the legal requirement to validate the source of funds. Customer due diligence (CDD), know your customer (KYC), and anti-money laundering (AML) laws apply even in the absence of a simplified system that would allow for the reporting of proceeds of crime and stolen coins.</p><p>The Bitcoin alert key was not added merely because of the vulnerability that had been announced a week earlier. I had been working on the alert key since July 2010. The patch to the vulnerability was announced on 15th August, 2010, and indeed, the alert system would be good for the notification of vulnerabilities. But here lies not the reason that Bitcoin had an alert system. The patch was created rather expeditiously, in response to the overflow bug and as a temporary disabling of certain prescription operators. My implementation of script had a lot of vulnerabilities at the time.</p><p>I avoided talking about such things because the inevitable tinfoil-hat brigade started talking about government shutting down Bitcoin. Government could always shut down Bitcoin. It still can. The US government can simply mandate banking restrictions in the same manner that they did on Black Friday across the gambling industry. Bitcoin could be isolated very quickly. By example, there are no exchanges operating as legal entities in China any more. All of them operate in jurisdictions that are controlled by the US. The US government would seize and control any Chinese, European, or American exchange as quickly as it desires. Even if Chinese miners decided to boycott an order requiring them to freeze funds, they would not be able to.</p><p>Any associated funds flowing to any exchange at any point following a freezing order will effectively be burnt. They may sell for fractions of a penny in the dollar, but even so, it is unlikely. The consequence is that Chinese miners or any others that sought to avoid a court order would find themselves earning around 1/1000 of the revenue of the miners that are following the court order. Very quickly, honest compliant miners would win. The cost would not decrease for the dishonest minor who seeks to breach the rules.</p><p>The alert key would protect users. In quickly being alerted and notified of assets that are frozen, individuals would not receive stolen funds or be deceived into believing that such had value.</p><p>“Send to address” would block an innocent user without notice from accidentally sending to a Bitcoin address that is covered by a freezing order. The system would allow individuals to engage in commerce and trade from different unblocked addresses, without violating court orders.</p><p>By August 2010, I was already rather disillusioned with many of the people involved with the Bitcoin project I had started. I had also become more sarcastic at the time. I had planned to implement further changes. And if it wasn’t for all the craziness and people seeking to create dark web websites that would use Bitcoin, I would have at the time. The thing is, it is still incredibly easy to mandate and do. My full version of a regulated Bitcoin system would have been far easier than what’s coming now. If it wasn’t for all the fools out there thinking that government is going to invade them and steal their bitcoin, things could have worked without anywhere near as much friction as shall be coming.</p><p>One thing I learned the hard way is that everything that should be simple becomes incredibly difficult with the “BTC community”. Many people have lived in the tinfoil-hat version of the world:</p><blockquote>No Taxes</blockquote><blockquote>There is no way for a third party to intercept transactions of Bitcoins, and therefore there is no viable way to implement a Bitcoin taxation system. The only way to pay a tax would be, if someone voluntarily sends a percentage of the amount being sent as tax. <em>[1]</em></blockquote><p>The student who created the report failed to analyse or understand Bitcoin to any extent. Rather, without seeking to understand the basis of accounting systems or how double-entry bookkeeping works, they falsely reported that Bitcoin was a system that gave users complete freedom to effectively do anything they wanted with their money, even if it was illegal. They went on to say that there was no way to intercept Bitcoin transactions and that there would thus be no way to implement a taxation system on Bitcoin. Right now, there are many forms of cash-based transactions that are not intercepted by government, and yet government manages to tax both businesses and individuals. In other words, even if bitcoin could not be seized or intercepted, the scenario does not preclude taxation. It is unfortunately such naïveté that has formed the basis of misconceptions around what Bitcoin is and how individuals act.</p><p>Taxes has existed on gold, and tax has existed in the cash economy. You do not get to opt out of the taxation system because you use Bitcoin. Nobody will ever own all their assets because of Bitcoin and a blockchain, and even if they did, it would be irrelevant. If you don’t pay your taxes, you go to prison, whether you use Bitcoin or not. If you fail to pay your tax, assets can be sequestered and taken from you. There is no system that changes the scenario; neither Bitcoin nor anything on a blockchain will ever alter the rules. At no point did I say Bitcoin would stop tax. The childish notion that Bitcoin could remove government or even help people avoid tax has no basis in reality. It has nothing to do with whether you think tax should be voluntary, it is a fact of life.</p><p>Employers and others will simply report you. They will maintain your identity in the way I envisioned Bitcoin to work, which is the way I presented in the white paper. Privacy will be maintained as individuals and organisations save identity data. Your employer will still gain deductions from your employment payment or salary, and they will report them to the government. More, they will report them with a fully auditable and traceable record. So, rather than removing tax, the introduction of a blockchain-based payment system will simplify the facilitation of tax without fraud or evasion.</p><blockquote>No Risk of “Charge-backs”</blockquote><blockquote>Once Bitcoins are sent, the transaction cannot be reversed. Since the ownership address of Bitcoins will be changed to the new owner, once it is changed, it is impossible to revert. Since only the new owner has the associated private key, only he/she can change ownership of the coins. This ensures that there is no risk involved when receiving Bitcoins. <em>[1]</em></blockquote><p>Non-reversal does not mean that bitcoin cannot be seized or taken from you. You do not own bitcoin because it’s on the blockchain, you own bitcoin which are stored in your wallet as indivisible tokens. Each bitcoin is made up of 100 million satoshi. There are no fractional satoshi. Each satoshi is an indivisible isolated token. The registered movement of control or possession of tokens simplifies micropayments. It does not do anything to remove the need to track ownership and larger values. Nobody is going to bring up the effort of reporting, following or tracing, and recovering five dollars’ worth of bitcoin. In small amounts, bitcoin acts as cash. For all of the BTC camp who want digital gold, the thing to remember is that gold has nothing to do with avoiding the law. If you buy and sell USD10,000 worth of gold, you do not own it unless you show ownership records. The purchase requires that you maintain information about the exchange. The same applies to bitcoin.</p><p>One of the most fundamental errors made with bitcoin stems from a failure to distinguish between a right and its record. The blockchain itself is a registration system. As such, the blockchain acts to maintain records of rights. The blockchain does not represent the rights themselves. Individuals hold bitcoin tokens in their wallet. Blockchain as a register is distinct from the rights to property itself. The recording of a transfer on the blockchain is distinct from the rights to the tokens being recorded. As a register, each blockchain-based system and even uses within the blockchain will function differently; it will depend on the form of the token whether it is fungible or linked such as in the case of a coloured coin.</p><p>Bitcoin is property and not a mere bearer instrument. Identity was always incorporated into the system presented in my white paper. For small transactions or casual exchanges, as would be carried out with cash, there is no requirement to legally mandate the capture of identity. In the event that an exchange passes certain threshold levels, there are requirements for the exchange to be fully documented and the identities of each party to be known. Know your customer (KYC) legislation exists in most Western nations and many others. You don’t get away from it because you use bitcoin. The error people make lies in believing that they own bitcoin merely because they hold it. You own bitcoin when you can prove, accordingly, the source of funds and how it was paid for. To own bitcoin, you require good title.</p><p>Bitcoin will not be reversed for small casual payments. I was very clear about the scenario in the white paper, where I said financial institutions or payment intermediaries who need to mediate disputes add costs. Here lies the weakness of the trust model, which is not that there is trust involved. As I said:</p><blockquote>The cost of mediation increases transaction costs, limiting the minimum practical transaction size and cutting off the possibility for small casual transactions.</blockquote><p>Bitcoin reduces the minimum practical size of micropayments, allowing them to be securely transacted between parties over the Internet. You do not remove the cost of mediation on large cryptocurrency exchanges. You do not remove the cost of mediation when using bitcoin worth over $10,000 (with the amount depending on the country you are in). The part of the same sentence that people cherry-pick is the following:</p><blockquote>The cost of mediation increases transaction costs, limiting the minimum practical transaction size and cutting off the possibility for small casual transactions, <strong>and there is a broader cost in the loss of ability to make non-reversible payments for nonreversible services </strong>[emphasis added].</blockquote><p>“Nonreversible services” are limited in scope. They involve small casual transactions. Blockchains do not stop courts from issuing orders such as a proceeds of crime order requiring changes to be implemented.</p><p>The big lie that is promulgated is that non-mining nodes would do anything at all, ever.</p><p>Non-mining nodes are simply slow, useless systems that act as ‘sibyls’ on the network, with people who lie about them to deceive regulators and defraud investors. They serve no purpose.</p><p>The lie of the ‘user-activated soft fork’ (UASF) node was told with the sole purpose of misleading regulators. You cannot simply fork Bitcoin towards a UASF protocol, while a freezing order would apply to both the un-forked protocol and everything to do with the forked protocol. The asset that you fork off with your non-mining nodes is still controlled by miners and exchanges. Any exchange that decides to use or list the new asset will be criminalised. Any coins following the frozen coin can indeed be followed and, under property rights, seized.</p><p>You see, it is not just a matter of you having bitcoin; if you don’t have good title to the bitcoin, and you don’t maintain all the identities concerning how you got it, someone can come knocking on your door and require that you give it up or, equally, give up the value in cash that corresponds to the amount of bitcoin you refused to hand over. Failure to do so can be covered under contempt of court orders and more.</p><blockquote>Bitcoins Cannot be Stolen</blockquote><blockquote>Bitcoins’ ownership address can only be changed by the owner. No one can steal Bitcoins unless they have physical access to a user’s computer, and they send the bitcoins to their account. Unlike convential &lt;sic&gt; currency systems, where only a few authentication details are required to gain access to finances, this system requires physical access, which makes it much harder to steal. <em>[1]</em></blockquote><p>It was stupid to think so when it was first said, and it remains stupid to think so now. Bitcoin can be recovered. The reason bitcoin won’t be stolen in large quantities, even though it has been in the past, is that it can be recovered from the thief.</p><figure><img alt="" src="https://cdn-images-1.medium.com/max/940/1*7a5l1gNPCiW0tSwcMXznVA.png" /></figure><p>When I said, “Imagine if gold turned to lead when stolen”, Bitcoin was still in the alpha phase. The alert key was not complete; code that would enable nodes to follow court orders and alert on freezing orders was still on the drawing board. Identity systems had not been created.</p><p>They have now. The system, in its entirety, is possible now.</p><p>Read the full article and more on my personal blog <a href="https://craigwright.net/blog/alternative-coins-systems/ledgers-and-design/">here</a>.</p><img src="https://medium.com/_/stat?event=post.clientViewed&referrerSource=full_rss&postId=22f9f2eaacc0" width="1" height="1" alt=""><hr><p><a href="https://medium.com/nchain/ledgers-and-design-22f9f2eaacc0">Ledgers and Design</a> was originally published in <a href="https://medium.com/nchain">nChain</a> on Medium, where people are continuing the conversation by highlighting and responding to this story.</p>]]></content:encoded> </item>
