Zhou Xiaochuan's blockchain

1. It is reported that the Central Bank of China is testing the digital currency based on blockchain
according to media reports, the people's Bank of China has completed a test on December 15, which shows how to conct transactions and clearing in the distributed ledger system
it is reported that this test was concted jointly with China's mainstream commercial banks, including ICBC, Bank of China and Weizhong bank< The report reads: "the people's Bank of China believes that digital currency can not only rece circulation costs, but also increase transparency, inhibit money laundering and tax evasion."
the report even suggests that Shanghai bill exchange pilot digital currency and set up a national bank bill transaction. At the same time, the people's Bank of China will also establish a digital currency Research Center, and is recruiting experts in big data, cryptography and blockchain technology< The report comes after Zhou Xiaochuan, the governor of the people's Bank of China, issued a statement in February in which he hinted that the people's Bank of China was considering using blockchain to issue digital currency
moreover, this test was concted at the time when the people's Bank of China launched an investigation into China's bitcoin exchange, which started early this month and has led to many changes in trading policies
as the world's first standard digital currency, Puyin takes 1 billion Tibetan tea as the primary standard asset, writes 1 billion Tibetan tea assets into the blockchain through digital encryption technology, and records the identification, evaluation and right confirmation of Tibetan tea.

2. After the people's Bank of China announced the launch of digital currency as soon as possible in January this year, Zhou Xiaochuan, governor of the people's Bank of China, recently gave a detailed description of the development of digital currency in an interview with Caixin weekly
Zhou Xiaochuan pointed out that as legal tender, digital currency must be issued by the central bank. The issue, circulation and transaction of digital currency should follow the idea of integration of traditional currency and digital currency, and implement the same principle of management. That is to say, q-coin and the like are definitely not good
as for whether to use blockchain technology to create digital currency. Zhou Xiaochuan said that the blockchain technology is an optional technology, but so far, the blockchain still occupies too many resources. Whether it is computing resources or storage resources, it can't cope with the current transaction scale, and whether it can be solved in the future depends on it. Zhou Xiaochuan said that in addition to blockchain technology, the digital currency research team of the people's Bank of China has also concted in-depth research on other related technologies involved in digital currency, such as mobile payment, trusted and controllable cloud computing, cryptographic algorithm, security chip, etc
it is certain that the digital currency issued by the central bank can never be the same as bitcoin, Ruitai, Qianjin card and other digital currencies. The digital currency issued by the central bank is just the digital currency.

3. There is no established timetable for digital currency
Zhou Xiaochuan pointed out that as legal tender, digital currency must be issued by the central bank. The issue, circulation and transaction of digital currency should follow the idea of integration of traditional currency and digital currency, and implement the same principle of management. That is to say, q-coin and the like are definitely not good

Zhou Xiaochuan said that in addition to blockchain technology, the digital currency research team of the people's Bank of China has also concted in-depth research on other related technologies involved in digital currency, such as mobile payment, trusted and controllable cloud computing, cryptographic algorithm, security chip, etc
in addition, Zhou Xiaochuan also mentioned that there is a lot of discussion about "51% attack" (assuming that indivials have 51% of the computing speed of the whole network, they can realize double payment, reverse transactions, paralyze the whole network, and completely lose the transfer function). More specifically, compared with the special currency, bitcoin does not need the central bank. Zhou Xiaochuan mentioned that for the digital currency controlled by the central bank, a series of technical means, mechanism design and laws and regulations will be adopted to ensure the security of the digital currency operation system, which is different from the design idea of bitcoin from the beginning
as for the digital currency timetable, Zhou Xiaochuan said that there is no established timetable. The relationship between digital currency and cash will be parallel and graally replaced for quite a long time. For reference.

4. Zhou Xiaochuan believes that bitcoin's blockchain technology has great potential. Zhou Xiaochuan compares bitcoin to a tradable asset like a stamp. Bitcoin is not issued by the central bank, which has no right to ban it. The central bank also plans to launch digital currency, which defines bitcoin as a special Internet commodity that people can buy and sell freely at their own risk
other well-known digital currencies include Leyte, Ruitai, doggy and so on.
