Supreme Court bitcoin legal
at the end of June 2013, after the German parliament decided that bitcoin would be tax-free if it was held for more than one year, bitcoin was recognized as a "unit of account" by the German Ministry of finance, which means that bitcoin has been regarded as a legal currency in Germany and can be used to pay taxes and engage in trade activities< In August 2013, judge Amos mazant of Texas District Court ruled in a case of bitcoin virtual hedge fund that bitcoin is a kind of currency and should be included in the scope of financial regulation
legal status
bitcoin can still be considered as legal at present. In the world, bitcoin can be regarded as a virtual commodity and protected by law; If bitcoin cannot be officially recognized as a kind of currency by law, it may bring inconvenience to the businesses and indivials who accept bitcoin in tax declaration, because the businesses who accept bitcoin will be regarded as barter transactions, and such transactions are more troublesome than ordinary transactions in tax declaration
at the same time, bitcoin, as a commodity highly similar to currency, needs to meet the demand of anti money laundering. Bitcoin needs to be included in the personal property declaration, banking anti money laundering system, anti insider trading, anti market manipulation and other systems in terms of transaction and possession. Bitcoin exchanges and storage institutions may also need government supervision and licensing. Some fast-growing bitcoin exchanges and payment service providers are actively exploring cooperation with regulatory agencies to bring bitcoin payment into the regulatory framework of anti money laundering and anti-terrorism financing by applying for licenses and actively communicating with regulatory authorities
in Europe, the European Central Bank published a report on "virtual currency architecture", and the French bitcoin trading platform obtained the PSP qualification. On December 6, 2012, the central bank wrote in the report: "this report is the first attempt to provide a basis for discussing the virtual currency system. While these systems may play an active role in financial innovation and in providing consumers with alternative means of payment, they also clearly create risks. " "Because of the small size of virtual currency systems, these risks do not affect anyone other than the users of these systems," the report added The report reviews the history of bitcoin and reviews its basic features, including currency and technical operation.
There is no law in China to ban bitcoin, so it is not illegal to mine and earn bitcoin
it is not illegal to buy bitcoin in China. In 2013, five ministries and commissions jointly issued the bitcoin risk notice, which states that although bitcoin does not belong to legal tender and is not legally compulsory, people can freely participate in bitcoin trading activities when they voluntarily undertake risks
"notice" clearly defines the nature of bitcoin, and holds that bitcoin is not issued by the monetary authority, has no monetary attributes such as legal compensation and mandatory, and is not a real currency. In terms of nature, bitcoin is a specific virtual commodity, which does not have the same legal status as currency and cannot and should not be used as currency in the market
however, as a kind of commodity trading on the Internet, ordinary people have the freedom to participate in bitcoin trading at their own risk
the notice requires that at this stage, financial institutions and Payment institutions shall not price procts or services with bitcoin, buy or sell bitcoin as a central counterparties, underwrite insurance business related to bitcoin or include bitcoin in the scope of insurance liability, and provide other bitcoin related services to customers directly or indirectly, Including: providing bitcoin registration, trading, clearing, settlement and other services for customers; Accept bitcoin or use bitcoin as a payment and settlement tool; Carry out bitcoin and RMB and foreign currency exchange services; Carry out bitcoin storage, custody, mortgage and other services; Issuing financial procts related to bitcoin; Take bitcoin as the investment target of trust, fund, etc

according to the regulations on the administration of RMB, the proction and sale of token tickets are prohibited. Because there is no clear judicial interpretation of the definition of token ticket, if bitcoin is included in the "token ticket", the legal prospect of bitcoin in China will face uncertainty< On June 4, 2009, the notice of the Ministry of culture and the Ministry of Commerce on strengthening the management of virtual currency in online games (Wen Shi Fa [2009] No. 20) stated that the scope of application of virtual currency in online games was defined for the first time, and a distinction was made between the current virtual currency in online games and the virtual props in games; At the same time, the notice said that the "notice" stipulates that enterprises engaged in related services must be approved before they can operate
in China, some Taobao stores have begun to accept the use of bitcoin, and the number of businesses will graally increase
in October 2013, the first bitcoin quarterly, one bit, was released
on October 15, 2013, the network accelerator service of the network announced its support for bitcoin
on October 26, 2013, btcmini reported that GBL was hacked
on October 31, 2013, Lei Teng, a famous Internet lawyer, proposed the event of "filing a case to investigate the closure of GBL bitcoin trading platform as soon as possible", analyzed the "value function" and "use function" of bitcoin, and bitcoin should be governed by relevant laws.
[characteristics of bitcoin]
the reason why bitcoin is anonymous is that they are built on a decentralized system. Bitcoin is completely independent, and the outside world cannot shut it down through some kind of core infrastructure
"anonymity" is very useful for those who don't want to associate their name with the goods or services they purchase. What outsiders see is nothing more than the address of your bitcoin wallet and a string of random words and numbers. Besides, there is no information that can identify themselves. For relatively paranoid users, they can also create many new wallets for free.
bitcoin is designed to allow anonymous ownership and use rights. Bitcoin can be stored in personal computers in the form of computer files (wallets) or in third-party hosting services. No matter how it is saved, bitcoin can be sent to anyone on the Internet through its address. The distributed characteristics of P2P and the design of no central management mechanism ensure that no organization can manipulate the value of bitcoin or create inflation. Its main features are as follows:
< UL >decentralization
bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of the security and freedom of bitcoin
< UL >circulation around the world
bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
< UL >exclusive ownership
the private key is required to manipulate bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
< UL >low transaction cost
bitcoin can be remitted free of charge, but in the end, a transaction fee of about 1 bit will be charged for each transaction to ensure faster execution of the transaction
< UL >no hidden cost
as a means of payment from a to B, bitcoin has no cumbersome limit and proceres. If you know the other party's bitcoin address, you can pay
< UL >cross platform mining
users can explore the computing power of different hardware on many platforms
[bitcoin acquisition method]
first of all, your computer should be installed with the latest version of bitcoin client. After opening the client, all the transaction information data on the network will be automatically downloaded to the local. Depending on the network speed, this process may take several hours. At this time, the account balance is 0. Users can ask friends to send some coins, but a more feasible way is to do mining or merchant acquisition[ 6]
< UL >
mining as a miner
to be a miner is to proce bitcoin with one's own computer. In the early client, there was the option of mining, but it has been cancelled. The reason is very simple. With more and more people participating in mining, it may take several years for one to dig 50 coins, So miners generally organize into miners' guild, and they dig together. Specific mining methods, you can go online search. This method is already very unrealistic
< UL >as a businessman, you can buy coins g by miners with money, open an online shop to sell things and collect bitcoin, and even go to the exchange to speculate in coins. There are many websites providing bitcoin exchange services, which can be converted into almost any kind of currency. If you really don't know how to exchange, you can also come to laoan for help
the difficulty of bitcoin mining is directly proportional to the amount of money that has been mined. The more difficult it is to mine, the more difficult it will be. After 20 million bitcoins are mined out in 2030, the remaining 1 million bitcoins will probably take decades to be mined out. And bitcoin has no central issuing authority, which is generated by network nodes through complex calculations. Anyone can run bitcoin software on a computer to make it. During circulation, enter the quantity 1 on the client software, then come to the other party's bitcoin address and sign with the payer's password. After that, the bitcoin is the other party's

On the afternoon of December 5, 2013, the people's Bank of China issued the notice on preventing bitcoin risks. In the notice, the people's Bank of China said that bitcoin is not a currency, but a virtual commodity. Financial institutions and Payment institutions are not allowed to carry out business related to bitcoin. As soon as the notice was issued, bitcoin fell sharply on China's trading platform, and it has dropped by 60% in three weeks. This is the beginning of bitcoin being restricted by the Central Bank of China. In mid March 2014, the people's Bank of China issued a notice on further strengthening bitcoin risk prevention to all branches of the people's Bank of China, which required all banks and third-party payment institutions to close the trading accounts of 15 domestic bitcoin platforms before April 15. This shows that it is illegal for financial institutions in China to open trading accounts for bitcoin website platforms. Except for cash transactions, bitcoin investors can not conct bank transfer and third-party payment for transactions in China< br />
Personally, I don't think blockchain development technology is reliable. It's just what kind of R & D technology group you choose. Even if you choose a better R & D technology group, you may not be able to achieve the blockchain technology you require. Different instries and fields have different technical indicators, not to mention this complex new technology. On the other hand, let the R & D technology group agree with the machine instry thinking you need to apply, otherwise the procts developed will not meet your requirements. We focus on the professional field of blockchain technology, and the project has been carried out for more than a year, but it has not been successfully implemented. The difficulty is that overthrowing the traditional model will touch a great chain of interests, so it must be a process of graal infiltration
according to what you said: blockchain based on machine learning can be understood as asking a technical question
I hope the above answers can help you
