Bitcoin mining supervision
No illegal
in the bitcoin risk notice jointly issued by the people's Bank of China and other five ministries and commissions at the end of 2013, bitcoin is clearly defined as a special Internet commodity, and people can buy and sell it freely at their own risk. But it denies the monetary nature of bitcoin< The Article 143 of the general provisions of the civil law stipulates that "the civil legal act with the following conditions is valid:
(1) the actor has the corresponding capacity for civil conct< (2) the expression of intention is true< (3) it does not violate the mandatory provisions of laws and administrative regulations, public order and good customs. " The announcement of the seven ministries and commissions is neither a law nor an administrative regulation, and can not be used as a legal basis for judging whether a civil juristic act is valid or not; The law does not go back to the past. Therefore, the bitcoin transaction has legal effect, and the bitcoin obtained from the transaction is protected by law. Therefore, legal disputes arising from trading activities, including civil or criminal cases, should be subject to jurisdiction. Courts or public security organs can not refuse to accept bitcoin because they think bitcoin is not protected by law

transaction mode
bitcoin is e-cash similar to e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free
a bitcoin address is a string of about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it does not need to exchange information online when generating address, so it can be offline [2]. More than 2 bitcoin addresses are available. Figuratively speaking, there are about two grains of sand in the world. If there is an earth in each grain of sand, then the total number of bitcoin addresses far exceeds the number of all the sand on all these "earths"
the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which records how much bitcoin you have on it. You can generate bitcoin address at will to store bitcoin. When each bitcoin address is generated, a corresponding private key of the address will be generated. This private key proves that you have ownership of the bitcoin at that address. We can simply understand the bitcoin address as the bank card number, and the private key of the address as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep your address and private key when using bitcoin wallet
after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed. Bitcoin P2P stores all transaction history in a "blockchain.". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. Blockchain is actually a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history. Nakamoto predicts that when the amount of data increases, users hope that not all the data will be stored in their own nodes. In order to achieve this goal, he uses the hash function mechanism. In this way, the client will be able to automatically eliminate those parts that it will never use, such as some very early bitcoin transactions
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
in order to avoid over hype of virtual commodities such as bitcoin in the name of "virtual currency" and damage the public interest and the legal tender status of RMB, the circular requires financial institutions and Payment institutions to correctly use the concept of currency in their daily work, pay attention to strengthening the ecation of the public's knowledge of currency, and correctly understand the concept of currency The concept of correctly treating virtual commodity and virtual currency, rational investment, reasonable control of investment risk, and maintenance of their own property security should be included in the content of financial knowledge popularization activities, so as to guide the public to establish a correct concept of currency and investment

As of July 24, 2020, the state has not issued any laws to prove that bitcoin mining machine is illegal
bitcoin mining machine is one of the ways to obtain bitcoin. Bitcoin is a kind of network virtual currency proced by open source P2P software
it doesn't rely on the issuance of specific monetary institutions, and it is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
extended data
the issue and transaction of bitcoin are realized by mining, and it is cast at a certain but slowing rate. Each new block is accompanied by a certain number of new bitcoin from scratch, which is used as a coinbase transaction to reward the miners who find the block
the reward for each block is not fixed. For every 210000 blocks mined, it takes about four years, and the currency issuance rate is reced by 50%. In the first four years of bitcoin's operation, each block created 50 new bitcoins. Each block creates 12.5 new bitcoins. In addition to the block award, the miner will receive a handling fee for all transactions within the block<

however, it has not been fully and effectively regulated at present (as of March 6, 2019)
if we understand bitcoin as a kind of "currency", then it is equivalent to US dollars leaving the United States. Usually, after the US dollar leaves the United States, banks in other countries will help manage it. However, it is impossible to count the scattered us dollars that are neither in the United States nor in the hands of banks and other financial institutions. For example, in some areas of Africa where there are no banks, the US dollar is used
these scattered us dollars are equivalent to bitcoin
how to regulate these scattered us dollars
generally, in addition to controlling the issuance of US dollars, US dollar regulation also controls the circulation and usage ports. The Federal Reserve controls the number of new currencies issued each year according to the flow and damage of dollars abroad. At the same time, we should supervise the inflow and outflow of US dollars, so as to keep us dollars in an environment that can be roughly traced, so as to facilitate the issuers to count the total amount, so as to avoid excessive inflation or deflation
in fact, these scattered us dollars exist in some deregulated environments. Although they are out of control, they will not affect the overall economic situation
If anyone wants to influence the international economy through these scattered us dollars, then it must enter the existing regulatory system. In this way, these scattered dollars are regulated
for bitcoin, we can also learn from these forms of regulation
first of all, from the point of view of the issuing end, although the total number of bitcoin is now 21 million, it is also "set before" and cannot be changed
recently, it has been mentioned that the 21 million bitcoin limit should be abolished, which means that the issue of bitcoin is not stable. Therefore, it is necessary to control the issuance of bitcoin from the development end
you need to get inside the development side and become a core developer
Second, monitoring from the circulation link. In fact, this is the most difficult monitoring at present, because the blockchain is anonymous, the user is anonymous, and the receiver is anonymous
even though we can trace the circulation path of bitcoin by technical means (for example, we can know that a transaction is sent from a small house in the United States to a commercial building in Germany), it is only a drop in the bucket for tens of millions of users in the whole environment. How to trace and manage the overall transaction data is a huge problem
you can't know from the transaction data whether the user is engaged in illegal transactions
what should we do? Regulators have come up with a way to bind personal identity information to the user's real name, your exchange account number and bitcoin wallet address. But this is also a temporary solution, because it can only monitor the use of bitcoin in specific situations. An indivial can use multiple bitcoin wallet addresses. You don't know when he will apply for a new one
in terms of circulation, there is also a monitoring system to control the exchange channel between bitcoin and local legal currency. Banks in some regions do not provide financial services for users who exchange bitcoin for legal currency, and some countries and regions prohibit financial institutions from providing bitcoin and local legal currency exchange services
if users secretly exchange huge amounts of bitcoin, some clues can be found through the bank transfer records, so as to crack down on illegal acts in time. As for those who make little trouble, let him go
thirdly, restrict the use. This is relatively easy to achieve. For example, relevant laws have been issued to prohibit the use of bitcoin transactions. Although it's impossible to ban it completely, it's better than letting it run wild All over the world, it seems that what is forbidden is not completely forbidden
for example, before using bitcoin in public, you must use your real name, and you have to pay taxes to hold or use bitcoin
of course, it's OK for users not to do so, so it's better to use its assets in the dark
having said so much, now you know that bitcoin can be regulated, but it's not so well managed. Many measures have been taken, and it seems that they are not effectively regulated. Under what circumstances can bitcoin be effectively regulated? Users consciously report their holdings of bitcoin to the regulatory authorities. The regulatory authorities add some development functions to the bitcoin to achieve supervision, or they don't need to use it, so it doesn't matter at all
in fact, it can't be controlled so strictly, as long as it can't be controlled in the range of big waves. After all, there is light and dark, and there may be no gray space at all
new technology will surely have an advantage when it comes to living now.
It's not against the law
The laws and administrative regulations in China do not prohibit the proction, holding and legal circulation of bitcoin, nor do they prohibit the sale of bitcoin mining machines2. The investment and transaction of "virtual currency" represented by bitcoin are on the rise. For this kind of virtual goods generated in the Internet environment after the development of Internet technology, there are policy and commercial risks in related transactions. However, under the premise of not violating the mandatory provisions of laws and administrative regulations, the contract signed by the parties is a valid contract
3. Bitcoin is generated by "miner" and "mining", and "miner" can be assumed by anyone in any place in the world. "Mining" is a process in which "miner" provides certain computer computing power according to the open source software provided by the designer, and obtains the special solution of the equation through complex mathematical operations, The miner who gets the special solution gets a certain amount of bitcoin reward
Because bitcoin is based on workload proof, it is related to computing power. To have computing power, we need to consume power, so its power consumption is very large. It is precisely because of such a large power consumption that the safe and stable operation of bitcoin system can be guaranteed
extended information:
according to the data of btc.com website, up to now, the computing power of the whole bitcoin network is about 51.65 eh / s, which is equivalent to 1.84 million bitcoin S15 (28T computing power, 1596w power) mining machines in operation, and the daily power consumption is about 69.92 million kwh. Divided by the current proction of 1800 bitcoins per day, excluding other costs, each bitcoin will consume 38800 kwh of electricity. "
from this point of view, although the current price of bitcoin is expensive, the cryptocurrency market website coinmarketcap.com shows that the current unit price is about $7900, but the cost of mining a bitcoin is not low at all
Recently, German Finance Minister Peter altemir and French finance minister Bruno lemer jointly held a press conference in Paris, saying that they will jointly promote the global supervision of the bitcoin at the G20 summit in Argentina this year, which will warn that the world's most popular cryptocurrency is being used by illegal groups
the regulation of bitcoin is likely to become a new topic of the G20 summit this year. Lemer has repeatedly said that he will propose to discuss the issue of bitcoin at the G20 summit. As for speculative risk, member countries need to discuss the regulation of bitcoin management together. US Treasury Secretary mu nuqin also said recently that he will work with the G20 to prevent cryptocurrencies such as bitcoin from becoming the digital equivalent of anonymous Swiss bank accounts
Experts suggest that the G20 and some international financial institutions should speed up the formulation of relevant principles and guidelines to provide cases and follow-up for countries to establish coordinated regulatory policies. At the same time, we should achieve global coordination in supervision to jointly crack down on illegal cryptocurrency transactions and crimesif the operation is proper, the mining company you invest in will continue to operate, and you may get the expected income
if the operation is improper, the mining company you invest in will go bankrupt or encounter other problems, and your investment will be more dangerous
so be cautious in mining, and there are more pits
