Domestic and foreign policies on blockchain
European and American countries are actively monitoring. Germany is the first country to recognize bitcoin and other digital assets as private property. The US CFTC (US Commodity Futures Commission) has identified bitcoin as a commodity. The state of New York has issued three bitlicenses
the situation in Asia is different. Japan actively supports it. In April this year, Japan implemented the payment services act, officially recognizing bitcoin as a legal payment method
South Korea is actively monitoring. In July, South Korea's "bitcoin Regulation Act" came out, setting a threshold of 500 million won for investors
China has strict supervision. In September, the people's Bank of China and other seven ministries and commissions jointly issued the "notice on preventing the financing risk of token issuance", which stipulates that in China, trading platforms shall not engage in the exchange business between legal tender and "virtual currency".

based on the legal framework, the blockchain technology makes the transaction information more secure and transparent, and the data more traceable through the pre-set automatic execution of intelligent contracts, which greatly reces the cost of law enforcement, presents the situation that the law and technology complement each other, and the law and economy are integrated, which makes the legal constraints and enforcement graally move towards intelligence
what is blockchain
blockchain is an innovative application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies in the Internet era
blockchain is essentially a decentralized distributed ledger database. It is a series of data blocks associated with cryptography. Each data block contains the information of effective confirmation of multiple bitcoin network transactions, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
foreign legal regulations on blockchain
as the blockchain technology itself is still in the exploration stage and has not been applied on a large scale, only some countries have enacted special legislation on blockchain technology< In the United States, Vermont and Arizona have passed bills to clearly define and support blockchain technology for public use. The bill stipulates the use specifications of blockchain and smart contract, and states that all data related to blockchain are "considered as electronic format and become electronic records", which is recognized by the state
UK
distributed ledger Technology: beyond blockchain mentions that the UK federal government will invest in blockchain technology to analyze the potential of blockchain application in traditional financial instry
Singapore
the government supports financial technology enterprises such as blockchain technology, and has launched a regulatory sandbox to provide a more tolerant development environment for blockchain start-ups
China's legal regulation on blockchain
in addition to the above-mentioned policies on blockchain itself, a series of regulatory provisions have been issued internationally for virtual currencies such as bitcoin
in our country, in addition to the policies on the transaction and financing of bitcoin and other virtual currencies, the government has also issued many policy regulations on blockchain
on December 27, 2016, blockchain technology was listed in the notice of the State Council on printing and distributing the 13th five year plan for national informatization. At the same time, the State Council also issued a document "China's blockchain instry is expected to walk in the forefront of the world" to support the healthy development of blockchain
it is mentioned in the guidance of the general office of the State Council on actively promoting the innovation and application of supply chain that we should study and use emerging technologies such as blockchain and artificial intelligence to establish a credit evaluation mechanism based on supply chain. Promote the organic docking of various supply chain platforms, and strengthen the disclosure and sharing of credit rating, credit record, risk warning, illegal and dishonest behavior and other information< In the eyes of lawyers, the legal risks of blockchain technology
as a distributed system, blockchain is an innovative application in the field of technology. According to the current exploration results, its technical concept can bring great changes to the development of various instries
however, as the law has not yet issued clear instry standards and applicable norms for blockchain, there are still problems such as national supervision and legal regulation in the future
taking bitcoin as a typical digital currency as an example, the first problem we face is supervision. Bitcoin and other digital currencies based on blockchain technology are logically decentralized and opposed to centralized supervision
secondly, the application of blockchain technology has to face huge risks. Taking bitcoin as an example, loss, theft, attack, speculation, money laundering and all kinds of disturbances, doubts and events have been accompanied by the development of bitcoin
the wide application of blockchain technology is inseparable from smart contract, which defines commitment in the form of digital coding. The two sides of the transaction do not need to trust each other, all transactions are enforced by the code
however, the validity of the form and content of smart contract has not been formally recognized by the law and the judiciary. As the contract text in the form of digital coding, it is not clear whether it can constitute the elements of an effective contract and whether it can meet the authenticity, legality and validity of the evidence to be accepted by the judiciary
e to the decentralized nature of blockchain technology, its own rules are bound to conflict and contradict with social rules and national legal rules. It is precisely conflicts and contradictions, risks and problems that can stimulate motivation and imagination, including that of society, the state and indivials
in the process of transaction, virtual currency based on the application of blockchain technology has posed great challenges to the legal tender and financial system of various countries, and caused investment risks and even social problems.

In 2014, Barry Silbert, founder of secondmarket, separated the bitcoin investment fund from the original company and established grayscale investments
in 2015, gray investment company was merged into the newly established digital currency group (DCG). DCG is not only focused on digital currency and blockchain investment, but also an incubator for start-ups. In addition to gray investment company, DCG also has two subsidiaries, namely, genesis, a cryptocurrency OTC broker, coindesk, a blockchain news and information website, and more than 150 other blockchain companies / projects invested
after years of development, gray investment company has become the largest cryptocurrency asset management company in the world, and its cryptocurrency trust scale has reached US $2.58 billion
{rrrrrrr}
extended information:
in 2013, Barry Silbert, the founder, convinced the board of directors of secondmarket company to set up a bitcoin investment fund called bitcoin investment trust, which is the predecessor of gray scale bitcoin trust. It was not until September 2017 that gray investment's bitcoin trust fund began to grow explosively
it has become the largest bitcoin investment trust in the world, with more than 408500 bitcoins, nearly 2% of the total. In addition to bitcoin trust funds, gray investment company also launched BCH, ETH, etc, horizon, LTC, XLM, XRP and Zec trust funds, as well as grayscale digital large capital fund with mainstream currencies. Gray investment company's cryptocurrency trust procts provide convenience for institutional users to purchase cryptocurrency
Since the 1970s, a new energy, combustible ice, has been discovered in the deep sea around the world. If you listen to this term, you will be surprised! How can ice burn? In fact, combustible ice is a kind of crystal material formed by the combination of water and natural gas, which is called "natural gas water compound" academically. According to measurement, 1 cubic meter of solid combustible ice contains about 200 cubic meters of natural gas. Therefore, combustible ice has a strong combustion capacity and is a very important energy resource
The discovery of combustible ice was e to a chance. In the 1930s, in order to transport natural gas, people began to lay huge natural gas pipelines. The results show that the pipeline is often blocked. Cut the pipe open and see that it was blocked by ice like material. How can there be ice in the pipe? After research, it turns out that it is a combination of natural gas and water, with strong combustion abilitya large amount of combustible ice is stored in the frozen soil and seafloor, and the most abundant is in the deep sea. On the sea floor, combustible ice often forms huge deposits with a length of several thousand meters and a thickness ranging from several centimeters to 200-300 meters. In the United States, Canada and other coastal areas, it has been found that there are tens of billions of cubic meters of combustible ice resources, which can be exploited for hundreds of years. Russia, New Zealand, India, Japan and other countries have also found considerable reserves of seabed combustible ice resources. Combustible ice is also found in the East China Sea, South China Sea and Yellow Sea. It is estimated that the reserves of combustible ice in the world are very huge, at least more than twice of the total reserves of coal and oil. It has been hailed as the new energy of the future
There are some difficulties in mining combustible ice because it is deep in the ocean and frozen soil. So far, there is no successful experience in mining seabed combustible ice in the world. At present, there are two mining plans in people's imagination, one is to connect the pneumatic pump pipe with the receiving ship. The air pressure pump pipe extends directly into the sea floor, and the lower end of the pump pipe is a huge bell shaped object, which can cover an area under the water. There is also an automatic mining machine inside the bell, which will dig up the rocks with combustible ice on the seabed together with the combustible ice, smash them into pulp, and then transport the pulp to the receiving ship through the pneumatic pump pipe. On the receiving ship, the natural gas in the combustible ice is separated by heating and pressurizing, while the remaining marine sediments often contain other available substances, which are separated and extracted for the second and third time. Finally, the useless resial soil is poured into the seaanother solution is to directly decompose combustible ice into ice and natural gas on the sea floor, and then transport it directly to the ground gas storage tank, just like the natural gas in the rock stratum, and then transport it to the users who need natural gas from the gas storage tank. Compared with the former scheme, the transportation condition of the latter scheme is relatively simple, which is expected to save more mining cost. But the problem is that the decomposition technology of combustible ice on the seabed is still immature; In addition, this scheme can not make full use of other resources that may exist in the seabed of the mining area
