He examined millions of transactions on the Bitfinex exchange and found that Tether USDTUSD was being used to buy Bitcoin as soon as the price started to fall, in order to bump it back up again. In some cases, technical solutions may be available, or be developed, to provide greater certainty and reduce such risks. Instead, it could be stored centrally with a government agency, such as the land registry, acting as a TTP. A full discussion of this issue is beyond the scope of this paper.

Chow said that other pieces of the release give users more flexibility over their Bitcoin Core wallet. For example, users can store their wallets, or private keys, in another data directory if they want to. For the more tech-minded, check out the release notes for more details. But developers contend there are a couple reasons for the delay. First, the team says it wanted to see how SegWit actually worked on the network for a bit before supporting it, in case there were security vulnerabilities or other concerns, said Chow.

It treats Bitcoin like a traditional commodity such as gold, and compares its current supply volume with its rate of production — meaning that halvings are pretty important events, even if they can come across initially like an anticlimax.

And PlanB is even more optimistic about the future. Dec 16 Crack open the champagne and break out the party hats, because Bitcoin has only gone and done it. Double whoop. Jeff Dorman, Chief Investment Officer at digital asset investment giant Arca, summarized the situation pretty well, we think.

Good news - US banks can now hold Bitcoin on behalf of their clients. Jul 21 Ethereum catching up Thanks to a boost from the DeFi movement, Ethereum surpasses Bitcoin as the network that settles the most value per day.

New data from Messari showed that Etherum had taken over, which meant that the dollar on the value of both Ether and its DeFi tokens was now higher than that of Bitcoin.

While Bitcoin had been trading relatively flat in previous weeks, DeFi tokens on the Ethereum network had been topping the charts. The DeFi sector was gaining popularity, and fast, and other crypto currencies were beginning to emerge within the market that to give Bitcoin a run for its money. This explains why we see bigger pumps on ether than Bitcoin when the market moves upwards. Ethereum is evolving much faster than Bitcoin with the rapid growth in DeFi,.

It was formalized by Wuille in May as a soft fork, bundled together with an upgrade called Schnorr , which adds a new type of signature.

Happy 18th Birthday! Bitcoin Core 0. The update was overseen by Bitcoin Core maintainers and received contributions from over developers. One of the biggest updates was users' new ability to connect to their hardware wallet from places like Ledger and Trezor with the Hardware Wallet Interaction HWI tool, making the whole blockchain interaction even safer. This time though, a joke had the opposite effect, and Bitcoin got a bump on the back of it.

By , just four years later, there were over Defi applications in providing services ranging from basic lending to creating synthetic assets. Sucks for James. But were the gains real? He believes that a lot of it was actually due to coordinated price manipulation using another cryptocurrency called Tether USDTUSD — and it could have been done by just one rogue trader. He examined millions of transactions on the Bitfinex exchange and found that Tether USDTUSD was being used to buy Bitcoin as soon as the price started to fall, in order to bump it back up again.

The next day though, the Bitcoin Core Project got verified, so it all worked out. Please be aware of accounts trying to pass them self off as Bitcoin Core project's twitter account. Oct 05 Segregated Witness SegWit is the name for a Bitcoin protocol by which the block size limit on a blockchain is increased by removing signature data from Bitcoin transactions.

In August Bitcoin Core, the most popular protocol software, began to implement SegWit transactions. In response, some developers hard-forked Bitcoin to a separate blockchain called Bitcoin Cash. Handbags at dawn. Sep 15 Major new release with 0. The new release provides a bunch of bug fixes and optimization, including better fee estimates and more accessible fee bumping, initial support for multiple wallets in a single installation, and a number of significant performance improvements.

Sep 11 China shuts up shop One of the biggest global outposts of Bitcoin trading, the Chinese authorities have always had a love-hate relationship with the asset. In September they make their boldest move yet, ordering the closure of all Bitcoin and cryptocurrency exchanges in the country. Fork in the road In a massive upset, the ultimate event occurs. By boosting the blocks, the theory was that more transactions could then be processed, making it cheaper and faster to use.

What do you think? Two roads diverged in a yellow wood. Jul 17 People were pretty keen to see what happened — and a whole bunch of websites sprang up to track the admittedly unlikely possibility. It's absurd. I just wanted to eat my dick on TV.

He did, however, try to run for US President. Fun times. Jul 15 SegWit takes off The controversial Segregated Witness software upgrade is approved — oddly enough, sparking a slight dip in price, perhaps as traders price in the possible impact.

The upgrade was designed to improve a number of longstanding issues within Bitcoin. Gox to its knees back in But perhaps more importantly, the debate around scalability and block size.

World domination was pretty much inevitable. Growing pains Get set for a couple months of incredible growth. Jun 17 Upgraded again Bitcoin Core 0. May 03 Russia joins the crowd Russia suggests that it might legalize the use of cryptocurrencies — a pretty major deal for Bitcoin, which sees an immediate price jump.

Some cynical people think it could be to avoid sanctions on traditional banking channels, while others think it could be down to the Bitcoin benefits of speed, security and transparency.

Either way, it took a while to happen — President Putin finally signed the bill to legalize cryptocurrency in August It allowed people to trade Bitcoin, but banned its use as a means of payment. Russia suggests that it might legalize the use of cryptocurrencies.

New upgrade Bitcoin Core 0. Part of the establishment of an electronic identity is to associate electronic credentials such as a secret password or biometrics with the validated person. There are also other online services to help users mask their transactions, known as bitcoin mixing or laundry. This will likely depend on the functionality they seek to offer and on regulatory requirements.

For instance, a number of organisations are promoting the use of blockchain to allow individuals to manage their identity. Smart Contracts.

Other applications might require more complicated interactions, such as a series of related, sequential or conditional transactions. Their progress could be documented on a blockchain, to record that the goods have arrived at and departed from various intermediate locations.

Instead, the term essentially refers to a computer program that automatically brings about some specified action, such as carrying out transfers of, or executing other actions relating to, digital assets according to a set of pre-specified rules. The challenges involved in correctly capturing these semantics as smart contracts include validation and verification. The more a blockchain platform supports smart contracts, the more scope users have to use the platform for different purposes. Developers who want to create a simple blockchain for a predetermined purpose may opt to offer limited support for smart contracts, or only support smart contracts made of predefined components.

In Bitcoin, the functionality relating to transactions is brought about through a series of scripts or programs. To illustrate this point, we look at various ways in which blockchain technology is being used to create structures that resemble existing legal concepts, including contracts, companies, and securities. Below, we consider how existing law will apply to these new blockchain-based structures.

We will consider, in turn, issues arising under i contract law, ii data protection law, iii securities law, iv property law, v intellectual property and finally vi company law. For each area, we illustrate how the legal analysis is affected by the way in which blockchain technology is deployed in a specific use case. In reality, the creator of a smart contract will ordinarily need to explain his offer to human counter-parties in human-intelligible language.

This explanation can form the basis of the agreement between the parties and thereby determine the terms of the contract. In doing so, A will communicate the details of her offer. On the one hand, standard contracts commonly include provisions that exclude all representations outside of the contract terms and provide a hierarchy between various legal documents.

On the other hand, simply publishing machine-readable code may not provide sufficient notice of contractual terms to non-expert counter-parties. Further, the code could be binding if the counter-party also uses a smart contract to express their assent, i. The two smart contracts will find agreement only if there is a set of computer-readable terms that are acceptable to both parties. However, as noted above, the legal contract between the parties is likely to include obligations beyond the code itself, based on other communications.

As a result, they are unable to capture the real-world complexity of all but the simplest transactions. The ledger then provides a reliable record of the transactions and contracts executed. Thus, while smart contracts might simplify execution, they will not prevent contractual disputes.

The offering party can replace the smart contract for future transactions, but cannot edit the existing smart contract or easily reverse its effects. However, since a legal contract is not self-executing, a party can withhold performance and renegotiate terms. A judge may then be able to correct obvious mistakes or incompleteness in contract language through interpretation, by assessing the intent of the parties.

Since a smart contract is self-executing, its automated performance is written into the blockchain. For instance, enforcement of the contract could, in theory, be structured to allow for arbitration by a third-party adjudicator with their own private key. It is not clear at present who these adjudicators would be or what procedural and substantive rules they would apply in resolving disputes. As a result, with a centralised platform, it should be easier to arrange a corrective fork.

The TTP or small group of trusted nodes can agree to correct the ledger. In a worst-case scenario, revealing information through a smart contract could lead to inadvertent loss of trade secret protection or to a breach of confidentiality. This is less of an issue on centralised platforms, where the TTP or trusted nodes can control visibility of the blockchain. For instance, it could be argued that the nodes and miners who collectively support the Bitcoin network offer a payment service to EU data subjects.

It refers to any operation or set of operations performed on personal data. It covers any information that relates to an identifiable person, i. For specific applications, for example a land registry blockchain, titles to property may be transferred from one named individual to another. In this case, the addresses might refer only to the sending and receiving banks in question and need not relate to any identifiable person.

For instance, in Bitcoin, the amount of BTC transferred does not necessarily relate to an identifiable person, [] nor would payment data for an overall end-of-day settlement between banks. For example, a group of retail banks could set up a blockchain platform to share KYC Know Your Customer information on their customers with each other. In that case, the object of transactions would be information about natural persons and could be written into the blockchain.

The controller is the natural or legal person who determines the purposes and means of processing personal data. On the one hand, at the macro-level, looking at the blockchain infrastructure as a whole, the purpose of processing personal data is to provide the associated service. For instance, with regard to Bitcoin, the purpose of processing transaction data is to provide a peer-to-peer system of electronic cash. They would also determine the means of processing, by deciding which software and hardware to use.

The user also determines the means , namely: to use that blockchain platform to execute their transaction. From this perspective, nodes and miners simply facilitate access to a blockchain database, while the users determine which data are stored there. Since data protection law is concerned with the processing of specific items of personal data, we consider the micro-level perspective more appropriate.

To illustrate this point, we consider three different use cases below. For instance, with a land registry, the government agency setting up the platform could either develop the underlying software in-house, or buy in software from a third-party developer. The agency could then run a single node and miner, acting as a TTP.

Similarly, at the macro-level, the agency would decide to process personal data on a blockchain platform for the purpose of providing a registry of titles to land. Seen from the macro-level, one could argue that the land registry should be considered a controller.

Users also arguably determine the means of processing by choosing the blockchain-based land registry as the medium to execute their transfers. Seen from this micro-level perspective, the user should arguably be considered the data controller, with the agency acting only as a processor on their instructions. For instance, it might use a Blockchain-as-a-Service BaaS offering, whereby a third party provides the underlying supporting infrastructure.

In such cases, the BaaS-provider could qualify as a sub-processor when processing personal data for the land registry. For example, even if we categorise the government agency running the blockchain land registry platform as a mere processor for the purpose of individual transactions, it may nevertheless be a controller for other purposes such as assessment and collection of taxes relating to land transactions. For instance, a group of retail banks may set up a blockchain to share information on their customers for KYC purposes.

The platform is closed only the founding banks, or others they authorise, can use it and private only the participating banks can view the blockchain database.

Thus, in specifying the software, the banks would determine which data to store on the blockchain and how it is processed through the consensus protocol. They could also dedicate resources to running the nodes.

The banks also arguably determine the purpose of processing, namely to share KYC information. Seen from this perspective, the banks could be characterised as controllers when setting up the platform and when acting as nodes and miners. In this case, the personal data would be the object of the transactions namely: the customer records. Banks enter this information onto the platform when submitting transactions.

In line with the above analysis, as users, each bank would arguably act as a controller with regard to the customer data it submits to the platform. Further, when processing the data as nodes and miners, the banks might be acting only as processors with regard to the customer data that other participating banks have submitted.

If they engage in further processing of the data for their own purposes, they would likely become controllers of that data. Open, Distributed Platform: Cryptocurrency. Given this, the miners and nodes arguably could be controllers. Thus, with respect to each item of personal data, the sending user decides to submit it to the Bitcoin platform for their own purpose, namely to transfer a certain quantity of value to the recipient. In addition, they arguably determine the means of processing, by deciding to use Bitcoin for their transaction.

Seen from this micro-level perspective, the users should be considered data controllers. Nodes and miners may simply process this data on behalf of each user. For instance, with cloud services, a customer can often only use a commoditised cloud service without modification and may have no choice but to accept the standard contractual terms offered by a large cloud service provider if they wish to use a particular service.

They should choose a cloud provider that guarantees compliance with the relevant requirements of data protection law. EU data protection law does not apply to natural persons in the course of a purely personal or household activity. However, if a user makes payments outside of a personal or household activity, such as for commercial, political, or charitable purposes, the exemption may not apply.

In such circumstances, users will typically be subject to the full responsibilities of a data controller, as set out in Section 6. Thus, if a node analyses the payments data in its local copy of the blockchain to glean commercial insights, it would become a controller in respect of any personal data involved. Conclusions Regarding Data Controllers and Processors. Given that data protection law is concerned with the processing of specific items of personal data, the micro-level perspective is arguably a more appropriate starting place.

Following this line of reasoning, users would be considered data controllers in respect of the personal data they submit to the blockchain platform, since they determine both purposes to execute the transaction and means in choosing the platform.

They delegate decisions on the technical and organisational details of the processing to the collective of developers, nodes, and miners. If nodes and miners merely process transaction data on behalf of users, they might merely be processors, rather than controllers.

In some cases, they may simply facilitate the processing of transactions on behalf of users, by passively running the relevant software. In this respect, they could be compared to providers of cloud computing services. Cloud providers offer Internet-based, flexible, location-independent access to computing resources, including processing capability and storage.

In that case, nodes and miners could be compared to SWIFT, a financial messaging service that facilitates international money transfers for financial institutions. However, the Article 29 Working Party determined that SWIFT should be considered a controller, since it acted with a significant level of autonomy in relation to the personal data it processed, including by developing, marketing, and changing the services it offered, deciding to establish a data centre in the US and to disclose data to the US Treasury.

Consequently, unless covered by the household exemption or another exemption , [] each user will need to be able to demonstrate one or more lawful grounds for processing the personal data they submit to the blockchain. For instance, in the above banking example, each bank will need to determine whether its existing grounds for processing customer data extend to processing by means of a private, permissioned blockchain.

As a result, they would not normally need to verify whether the controller has valid grounds for processing. Controller and Processor Obligations. Achieving this should generally be easier with closed, centralised platforms, since fewer parties are involved as nodes and miners, making it easier to coordinate compliance. For instance, in the above banking example, the banks would need to establish their respective responsibilities by means of a contract.

Similarly, the land registry would need to establish its legal responsibilities as a processor via contracts with the users of its platform. It would probably seek to do so by requiring users to agree to terms of service before accessing the platform. In theory, large numbers of users, nodes, and miners would need to enter into detailed contracts in order to establish their responsibilities. In practice, the most feasible way to achieve this may be through standard-form terms and conditions to be agreed whenever a user, node, or miner first uses a platform.

As noted above in Section 3. However, as argued above in Section 6. Nonetheless, developers have an interest in promoting their platform and may find that designing it to enable compliance attracts more miners, nodes, and users. For example, the Ethereum website contains standard-form terms and conditions governing the use of its software platform, the Bitcoin Core website does not. However, this is difficult for Bitcoin and Ethereum, since users need not interact with the software directly.

Returning to our earlier examples, in order to run a node in a third country, the land registry and banks would need to ensure an adequate level of protection or appropriate safeguards for instance by locating the node in a country subject to a Commission adequacy decision or by putting in place adequate safeguards such as via approved standard contract clauses.

Since any party in any third country can download the archive, adequacy decisions and appropriate safeguards including binding corporate rules are unlikely to provide sufficient coverage. These include a right to rectification of inaccurate personal data and to data erasure also known as the right to be forgotten.

However, the ability to comply with such requests differs, depending on the design of the blockchain platform. For example, if a user requested the banks to rectify a specific piece of information in their customer record on the blockchain, each bank could comply by altering the relevant transaction record and re-hashing the subsequent blocks in their copy of the ledger.

Operators of centralised platforms should similarly be able to comply with requests for erasure. A node can only alter its own local copy of the ledger. However, in practice, this level of coordination may be difficult to achieve among potentially thousands of nodes.

Good news - US banks can now hold Bitcoin on behalf of their clients. Jul 21 Ethereum catching up Thanks to a boost from the DeFi movement, Ethereum surpasses Bitcoin as the network that settles the most value per day.

New data from Messari showed that Etherum had taken over, which meant that the dollar on the value of both Ether and its DeFi tokens was now higher than that of Bitcoin. While Bitcoin had been trading relatively flat in previous weeks, DeFi tokens on the Ethereum network had been topping the charts.

The DeFi sector was gaining popularity, and fast, and other crypto currencies were beginning to emerge within the market that to give Bitcoin a run for its money. This explains why we see bigger pumps on ether than Bitcoin when the market moves upwards. Ethereum is evolving much faster than Bitcoin with the rapid growth in DeFi,.

Bitcoin has the ability to act as a more safe haven asset, and signs of a further deteriorating trade war with China could have been the primary catalyst to drive up Bitcoin prices following Trump's tweet,. Jul 16 Although most lawmakers were openly critical of Libra, Bitcoin came in for some surprisingly strong support.

May 06 Taproot upgrade to boost privacy Genius Bitcoin developer Pieter Wuille unveils two Bitcoin Improvement Proposals BIP that could be the next big upgrade for the cryptocurrency, offering major privacy improvements.

It was formalized by Wuille in May as a soft fork, bundled together with an upgrade called Schnorr , which adds a new type of signature. Happy 18th Birthday! Bitcoin Core 0. The update was overseen by Bitcoin Core maintainers and received contributions from over developers.

One of the biggest updates was users' new ability to connect to their hardware wallet from places like Ledger and Trezor with the Hardware Wallet Interaction HWI tool, making the whole blockchain interaction even safer. This time though, a joke had the opposite effect, and Bitcoin got a bump on the back of it.

There was some speculation that this was because of Bitcoin trading bots, or that automatic keyword searches by traders got people ahead of themselves, but either way it was a great boost for Bitcoin, which carried on with this impressive momentum well into the year.

When that passed with no major incident, the market gained a bit of confidence back. Mar 26 Twitter ban Prices sink 3. Joining tech giants Google and Facebook, Twitter announced that it would ban advertising for cryptocurrencies in an effort to protest investors from fraud.

Feb 26 Sweet Sixteen Bitcoin 0. Bitcoin 0. This release is sometimes referred to as the SegWit Special because most notably, it finally made Segregated Witness SegWit fully available for all wallet users along with adding a bunch of new features to the wallet interface.

SegWit is the name used for the implemented soft fork change in the Bitcoin transaction format. Segregated Witness itself first got introduced in Bitcoin Core 0. Feb 01 Chinese whispers China totally bans all Bitcoin trading on 1 February and shuts down all mining activity, leading to a massive price slump.

But Bitcoin is starting to make traditional bankers nervous. The clock is ticking Dec 28 MakerDAO was an Ethereum-based protocol, the first of many, that created a way for anyone to take out a loan without relying on a centralized institution like a bank by pegging cryptocurrency at 1-to-1 to the value of a dollar, and letting people use digital assets as collateral. By , just four years later, there were over Defi applications in providing services ranging from basic lending to creating synthetic assets.

Sucks for James. But were the gains real? He believes that a lot of it was actually due to coordinated price manipulation using another cryptocurrency called Tether USDTUSD — and it could have been done by just one rogue trader.

He examined millions of transactions on the Bitfinex exchange and found that Tether USDTUSD was being used to buy Bitcoin as soon as the price started to fall, in order to bump it back up again. We see you, Jamie. Oct 28 Oct 25 The aim was to reform the mining process in favor of smaller players. Oct 12 The unverified, at this point Bitcoin Core Project had a number of fake Twitter accounts circulating, pretending to be Bitcoin core developers and contributors, and spreading fake news.

The next day though, the Bitcoin Core Project got verified, so it all worked out. Please be aware of accounts trying to pass them self off as Bitcoin Core project's twitter account.

Oct 05 Segregated Witness SegWit is the name for a Bitcoin protocol by which the block size limit on a blockchain is increased by removing signature data from Bitcoin transactions.

In August Bitcoin Core, the most popular protocol software, began to implement SegWit transactions. In response, some developers hard-forked Bitcoin to a separate blockchain called Bitcoin Cash. Handbags at dawn. Sep 15 Major new release with 0. The new release provides a bunch of bug fixes and optimization, including better fee estimates and more accessible fee bumping, initial support for multiple wallets in a single installation, and a number of significant performance improvements.

Sep 11 China shuts up shop One of the biggest global outposts of Bitcoin trading, the Chinese authorities have always had a love-hate relationship with the asset. In September they make their boldest move yet, ordering the closure of all Bitcoin and cryptocurrency exchanges in the country. Fork in the road In a massive upset, the ultimate event occurs. By boosting the blocks, the theory was that more transactions could then be processed, making it cheaper and faster to use.

What do you think? Two roads diverged in a yellow wood. Jul 17 People were pretty keen to see what happened — and a whole bunch of websites sprang up to track the admittedly unlikely possibility.

It's absurd. I just wanted to eat my dick on TV. He did, however, try to run for US President. Fun times. Jul 15 SegWit takes off The controversial Segregated Witness software upgrade is approved — oddly enough, sparking a slight dip in price, perhaps as traders price in the possible impact.

The upgrade was designed to improve a number of longstanding issues within Bitcoin. Gox to its knees back in But perhaps more importantly, the debate around scalability and block size. World domination was pretty much inevitable. Growing pains Get set for a couple months of incredible growth. Jun 17 Upgraded again Bitcoin Core 0. May 03 Russia joins the crowd Russia suggests that it might legalize the use of cryptocurrencies — a pretty major deal for Bitcoin, which sees an immediate price jump.

Some cynical people think it could be to avoid sanctions on traditional banking channels, while others think it could be down to the Bitcoin benefits of speed, security and transparency.

Either way, it took a while to happen — President Putin finally signed the bill to legalize cryptocurrency in August It allowed people to trade Bitcoin, but banned its use as a means of payment. Russia suggests that it might legalize the use of cryptocurrencies. New upgrade Bitcoin Core 0. Apr 01 Japan takes the lead Japan officially recognizes Bitcoin as legal tender, a move that seems positive but may actually be a cynical attempt to regulate the currency and impose more restrictions on how people use it.

The official stamp of approval gave traders increased confidence. It also led to a surge of new exchanges in Japan, with 11 licensed by September alone. Japan officially recognizes Bitcoin as legal tender. Mar 10 Winklevoss woes The SEC rejects an application from superhero twin brothers Cameron and Tyler Winklevoss to launch the first Bitcoin exchange-traded fund. Mar 08 Some of the biggest changes included improved fee estimation and manual blockchain pruning, so users can get rid of older verified blocks and make space for new blockchain data.

Feb 09 Bitcoin-China breakup Bitcoin and China feel like that couple that keeps breaking up, bad-mouthing the other, and then getting back together again. It sends Bitcoin crashing down. The coming year, however, would tell a very different story.

Nov 09 Oct 11 Bitcoin has had a fairly up and down relationship with government and banking regulations, but it looked like central banks were gradually coming around to the idea of using blockchain technology, if not Bitcoin itself. In , a few banks also started looking into stockpiling Bitcoin to pay off cyber criminals who might threaten their systems.

Aug 29 You could buy an island or two with that. Luckily, it began bouncing back the next day. Jul 09 Bitcoin lost a further 9.

It seems a lot of the Brexitement was because of the belief that a No Deal Brexit might soften cryptocurrency regulations. Added to that, the negative impact on both sterling and the euro could make way for another player… a digital currency perhaps?

In fact, if the EU no longer governs UK regulations, the hope was that the UK might welcome Bitcoin with open arms to help bolster its economy. Either way, people were excited. Though the price took a hit on June 21, it recovered on June 23 when the referendum took place, though not quite to the same highs it was riding earlier in the month.

May 28 Bitcoin gets a May-jor boost The second halving is coming up. People are excited, and Bitcoin is reaping the benefits. There were a few different ideas about what exactly caused the May boost, but it was most probably a combination of a few different things. Rival currency Ethereum had entered the market a few months before and was drawing more attention to the digital currency ecosystem globally, as well as finally providing Bitcoin with some real competition.

Anticipation was also growing for the upcoming halving , and the possibility of Brexit was creating some excitement for the UK market, with the possibility that a split from the EU could benefits the digital currency.

Satoshi, is that you? Craig Wright comes out to a few media organizations as the real Satoshi, and Gavin Andreson publishes an article backing him. Investors seem used to this to-and-fro by now, because prices stay pretty steady. Two Bitcoin luminaries, Jon Matonis and Gavin Andreson, hopped on board and Andreson wrote in a blog post that he believed Wright was the original Bitcoin founder following private proof.

Wright went on to backpedal only a few days later, saying he was sorry but in fact could not provide proof of who he was. Wright admitted in a blog post that he was not strong enough to handle the criticism he had faced after claiming to be Nakamoto. I know that this weakness will cause great damage to those that have supported me, and particularly to Jon Matonis and Gavin Andresen.

I can only hope that their honour and credibility is not irreparably tainted by my actions. They were not deceived, but I know that the world will never believe that now. There is currently no publicly available cryptographic proof that anyone in particular is Bitcoin's creator.

Apr 26 Thoughts are that increased adoption of cryptocurrency tech in general could be behind the jump. Similarly, the land registry would need to establish its legal responsibilities as a processor via contracts with the users of its platform. It would probably seek to do so by requiring users to agree to terms of service before accessing the platform. In theory, large numbers of users, nodes, and miners would need to enter into detailed contracts in order to establish their responsibilities.

In practice, the most feasible way to achieve this may be through standard-form terms and conditions to be agreed whenever a user, node, or miner first uses a platform. As noted above in Section 3. However, as argued above in Section 6. Nonetheless, developers have an interest in promoting their platform and may find that designing it to enable compliance attracts more miners, nodes, and users.

For example, the Ethereum website contains standard-form terms and conditions governing the use of its software platform, the Bitcoin Core website does not. However, this is difficult for Bitcoin and Ethereum, since users need not interact with the software directly.

Returning to our earlier examples, in order to run a node in a third country, the land registry and banks would need to ensure an adequate level of protection or appropriate safeguards for instance by locating the node in a country subject to a Commission adequacy decision or by putting in place adequate safeguards such as via approved standard contract clauses. Since any party in any third country can download the archive, adequacy decisions and appropriate safeguards including binding corporate rules are unlikely to provide sufficient coverage.

These include a right to rectification of inaccurate personal data and to data erasure also known as the right to be forgotten. However, the ability to comply with such requests differs, depending on the design of the blockchain platform. For example, if a user requested the banks to rectify a specific piece of information in their customer record on the blockchain, each bank could comply by altering the relevant transaction record and re-hashing the subsequent blocks in their copy of the ledger.

Operators of centralised platforms should similarly be able to comply with requests for erasure. A node can only alter its own local copy of the ledger. However, in practice, this level of coordination may be difficult to achieve among potentially thousands of nodes. For instance, a blockchain application might not require storage of personal data on-chain, but rather provide links to such data residing externally.

Technical approaches targeting data protection issues are an active area of research and they are likely to receive an additional impetus due to legal obligations to demonstrate data protection by design.

Given the potential severity of penalties under the GDPR, there is a risk that this legal uncertainty will have a chilling effect on innovation, at least in the EU and potentially more broadly. ICOs raised an estimated U. Conversely, if the start-up fails to launch a valuable service, the tokens may become worthless, leaving investors with losses. It determined that ICO tokens can qualify as securities, depending on the facts of the case. Failure to do so can give rise to significant civil and criminal liability.

Ultimately, regulators will need to consider how to regulate ICOs in order to protect investors without chilling innovation. Without protection, investors risk being misinformed and suffering losses, which in turn is likely to undermine confidence in the market as a whole. As noted above in Section 2. Although tokens often have financial value, it is not clear to what extent they qualify as property under the law. This section considers the status of blockchain tokens under the property law of England and Wales.

Might that constitute theft? Alternatively, in future bankruptcy cases, a debtor may hold an amount of crypto-currency of significant value.

Could a court order the tokens be sold to repay creditors? Further, whether tokens qualify as property may depend on the legal context and the remedy sought, since an item might qualify as property in some contexts but not in others. Consequently, it was property at common law. In Your Response v. Business Media, the Court of Appeals sought to determine whether an electronic database was a form of property capable of possession, such that it could be subject to a possessory lien.

Instead, it seems likely that legislation would be required to introduce a new category of choses in virtual possession. Business Media, extending possession to intangible items could have significant unintended consequences, [] particularly given the many contexts in which a definition of property applies and the various types of digital assets which could be subject to virtual possession.

A full discussion of this issue is beyond the scope of this paper. The issue would likely benefit from further research. The debt is a right of action that can be transferred to other persons. In some cases, a token may represent a right that is substantially similar to an existing chose in action, such as a debt or share in the issuing company. In such cases, the token is likely to qualify as a chose in action. It arguably functions like a digital version of a documentary intangible , like a cheque or a bill of lading; where a physical document represents an intangible chose in action.

In such cases, the tokens are likely to constitute a chose in action, if the counterparty and rights associated with the token are clearly defined.

They resemble other forms of non-personal, transferable contractual obligations. For example, a company could issue special ICO tokens on top of the distributed Ethereum blockchain. First, unlike several other types of choses in action e. On a traditional view, if they are neither choses in possession nor in action, then they are arguably not property at all. However, it is unclear whether the common law as applied in England and Wales recognises a category of other intangible property other than choses in action and patents.

On the one hand, in Armstrong v. Winnington Networks, Stephen Morris QC appeared open to recognising other forms of intangible property. For example, the tort of conversion is only available for choses in possession, not choses in action. First, blockchain-related inventions that provide a novel, non-obvious technical solution that is capable of industrial application may be patentable.

To qualify for a sui generis protection right, there must have been a substantial investment in the creation of the database. For instance, they might invest in the presentation of the database by deploying human, financial, and technical resources in writing the blockchain software and then dedicating hardware to running nodes and miners.

If so, and provided they have sufficient links to an EU Member State, [] the right holders of a centralised platform would have the right to prevent extraction and re-utilization of all or a substantial parts of the contents of that database. The database right is owned by the maker of the database, being the person who takes the initiative and the risk of investing. It is unclear whether these activities, taken separately, amount to substantial investments , and if so, which of the activities would suffice for a party to qualify as one of the database makers.

This replicates some of the elements of a legal company, such as dividend-receiving shareholders and tradable shares, but using only smart contracts for enforcement.

The DAO was set up in as a funding vehicle for Ethereum-based projects, such as using smart locks to let people share their physical assets e. Such contentious hard forks may be unlikely for issues affecting fewer parties or deemed by the community as insignificant compared with the cost of implementing a fork.

In such arrangements, a TTP or group of trusted nodes store copies of the ledger, add new blocks, and determine which users can access the platform and view the ledger. Further, by working with a small number of high-capacity nodes, the systems may be better able to scale and process large numbers of transactions.

Instead, each application of blockchain technology will need to be considered on its facts. From a legal perspective, closed, centralised platforms are generally likely to entail lower risks in the areas we have reviewed.

The TTP or group of trusted nodes may be able to coordinate compliance, limit visibility of records, and reverse past transactions if necessary.

Achieving these goals is harder on open, distributed platforms that deliberately lack a central administrator with control over the ledger. For example, users on blockchain platforms engage in activities, such as setting up smart contracts and issuing ICOs, that have characteristics closely resembling established legal concepts, such as contracts and securities.

Engaging in these activities may have significant legal consequences. As a result, communications relating to smart contracts may qualify as enforceable legal contracts, giving rise to legal obligations that go beyond the underlying computer code. The ease of correcting such mistakes will depend on the type of blockchain platform involved.

Centralised blockchain platforms can support reversibility better: the TTP or group of trusted nodes may be able to correct any mistakes by amending erroneous transactions in the ledger, since they control the copies. However, on an open, distributed platform, correcting past mistakes would be more difficult, potentially requiring cooperation from thousands of nodes.

If so, they will need to comply with data protection obligations and may be exposed to substantial penalties for breaches of data protection laws. Whether the tokens issued under ICOs qualify as the legal property of their users is currently uncertain and will likely depend, to some extent, on the rights the token purchaser holds against the issuer.

In England and Wales, a transferable token that gives the user a definable right against a specific issuer may qualify as a chose in action. Conversely, the property status of cryptocurrency tokens on open, distributed applications like Bitcoin is unclear. If so, the right holder would have the right to prevent extraction and re-utilization of the contents of that database.

Determining the maker of the database who is awarded the right could be fairly straightforward for centralised platforms, but may be more challenging with open, distributed platforms. As a result, DAOs are unlikely to qualify as legal persons and, as a result, participants will not necessarily benefit from limited liability. Should a bug in the code lead to liability for damages, each DAO participant could conceivably be liable. As noted above, any such damages would be much more difficult to reverse in the case of open, distributed platforms.

In some cases, technical solutions may be available, or be developed, to provide greater certainty and reduce such risks.

In other cases, legislators, regulators, and legal advisers may need to design novel legal solutions. Times Mar. Authority Nov.
