extended information:

bitcoin:

bitcoin can be used to cash and can be converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

generation principle:

starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique. In the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million

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 />

The new blackmail virus is called Petya blackmail virus. According to foreign media reports, a variant of Petya extortion virus, which is homologous to wannacry extortion virus technology, broke out in the world on Tuesday. A number of large enterprises including the UK, Ukraine, Poland, Italy, Denmark, Russia and the United States reported that they were attacked by the virus. Among them, the government, state-owned banks, transportation, energy and other key infrastructure and departments in the hardest hit Ukraine were attacked, Even the prime minister's computer was attacked

similar to wannacry, unlocking Petya virus also requires payment of encrypted digital currency. It is reported that after the virus locks the computer, it requires users to pay $300 in encrypted digital currency to unlock it. According to the public data of the bitcoin trading market, there were 10 ransom payments in the first hour of the virus outbreak, and its "money sucking" speed completely surpassed that of wannacry. But the latest news shows that because the virus author's blackmail mailbox has been sealed, now the ransom can not restore the system
