Network mining cases
Online mining is real, that is, traffic mining
. The bitcoin system ensures that bitcoin will not be g out too quickly by adjusting the difficulty coefficient. Every 10 minutes, the whole network is absent from work to jointly calculate a difficult problem, compete for bookkeeping rights and bitcoin rewards. If the computing power of the whole network continues to grow, bitcoin will be g out soon. In order to ensure that bitcoin can be g out in about 10 minutes, Nakamoto designs the difficulty of mining for bitcoin, Every 2016 blocks (about 2 weeks) are dynamically adjusted, so that the difficulty after adjustment makes the expected time for each block to be generated 10 minutes. Now the difficulty coefficient is about 480ph / S (Note: September 2017), which is about 68 billion times that of Genesis block. In other words, with the current computing power, the miners in the whole network need to go through about 300 trillion hash operations to find a qualified answer, Generate a new block
. Compared with point-to-point trading, mining and other purchases on the trading platform are the most popular ways to obtain blockchain assets, that is, floor trading. Floor trading of blockchain assets is similar to stock trading. The platform can help you match up, and you don't need to know who your trading partner is. Your trading partner may be one person or many people, Whether it's buying or selling, the trading platform will record the hanging order price of everyone. The buyer and the seller can obtain the latest transaction price through the real-time order. At the same time, the trading platform will summarize the historical transaction price and volume into a K-line chart, which is convenient for investors to analyze the market trend. For example, the UTOR market is the mainstream trading platform in the world.
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<

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
According to reports, in April this year, Hanshan county power supply company found that the line loss of a section of high-voltage line in Lintou town of Hanshan County suddenly increased, nearly 10 times higher than the normal value. After section by section investigation, the line loss finally pointed to an abandoned factory in Lintou town
it is reported that after verification by the electric power department, Ma madly stole nearly 150000 kwh of electricity in more than one month. Ma was detained for theft. The case is under further investigation

Du Zhenyi, the prosecutor of Yuzhou people's Procuratorate, appeared in court to support the public prosecution, and the defendant Li and his defender Tian Junqi attended the lawsuit. The trial is now concluded
the people's Procuratorate of Yuzhou City alleges that from October 1997 to March 2004, the defendant Li mined the bauxite ore in the village without a mining license, resulting in the destruction of mineral resources, with a value of more than 300000 yuan
the defendant, Mr. Li, and his defenders argued that the defendant had already mined the mine by several people before contracting the mine, and the value of the indictment was too great, so they requested the court to give the defendant a lighter punishment
the trial found that: from October 1997 to March 2004, the defendant, Li, without a mining license, illegally exploited the state's mineral resources by organizing workers to exploit and contracting to others, resulting in the destruction of mineral resources, with a value of more than 300000 yuan
the evidence for determining the above facts includes the confession of the defendant Li, which proves the fact of mining bauxite without a license; The testimony of the witnesses Li Jinfa, Wang Qingnian and Li Minxuan is consistent with the confession of the defendant Li; The technical service center of Yuzhou Bureau of land and resources made a survey report on the defendant Li's mining pit, Yuzhou Bureau of land and resources made a request for the identification of Li's unlicensed mining, and Henan Provincial Department of land and resources made a confirmation letter on the survey report of the mine. After identification, Li destroyed the value of mineral resources by 604000 yuan. The above evidence, cross examined in court, is objective and true enough to be confirmed
the court held that the defendant, Mr. Li, violated the provisions of the mineral resources law by mining bauxite without a mining license, causing damage to mineral resources, and his behavior has constituted the crime of illegal mining. The accusation of the public prosecution organ should be supported. The defendant, Li Mou, and his defenders have different opinions on the amount of the charge, but they have not provided evidence to prove it. Their arguments are not supported because of insufficient reasons. In accordance with the provisions of article 343, paragraph 1, Article 52 and Article 53 of the criminal law of the people's Republic of China, the judgment is as follows:
the defendant Li, who committed the crime of illegal mining, was sentenced to fixed-term imprisonment of one year and a fine of 2000 yuan, and paid within 10 days after the judgment came into effect
(the term of sentence shall be calculated from the date of execution of the judgment. If a person is detained before the execution of the judgment, one day of detention is equivalent to one day of sentence, that is, from March 23, 2004 to March 22, 2005.)
