Development status of blockchain digital currency in China

1. blockchain is a kind of technology. "In the simplest and most popular way, blockchain technology is everyone bookkeeping, or distributed ledger."
in the Internet era, there is a database behind every system. This database can be regarded as a large account book. In the past, the person who maintained the system was responsible for managing the database and recording the user's behavior, that is, bookkeeping. However, the blockchain is "decentralized", which allows every member of the system to participate in it, not only everyone bookkeeping, but also through links, Everyone can have a complete account book
"blockchain is essentially a collective recording mode. What's special is that it adopts a set of techniques in an ingenious way to realize the authenticity and credibility of the recorded results, which is difficult to destroy and tamper with. " Zhang Xiaorong said, "first, everyone has the right to record and authenticate with each other to distinguish the true from the false, which is called consensus mechanism; Second, no one can tamper with the records, because there are cryptographic signatures; Third, everyone has a , so even if some account books are damaged, the whole will not be affected. This is called distributed storage. The information recorded in this way is presented in block mode according to the time chain, so it is called blockchain. "
various cryptocurrencies represented by bitcoin are originally an application of blockchain technology, which can be described as blockchain version 1.0. However, around 2014, the instry began to realize the important value of blockchain technology. Blockchain graally separated from digital currency and applied to various economic and social fields other than digital currency
it has broad application prospects
blockchain technology is considered as a disruptive innovation after steam engine, electric power and Internet. If the steam engine and electricity liberate the proctivity, and the Internet has changed the way of information transmission, the blockchain, as a machine for building trust, may change the way of value transmission
for example, in the financial field, the cost of reconciliation, clearing and settlement between financial institutions, especially cross-border financial institutions, has always been very high, and there are complex manual processes. The application of blockchain technology can help rece the cost of reconciliation and dispute resolution between financial institutions, and significantly improve the processing speed and efficiency of payment business, It also makes small cross-border payments possible. In December 2017, China Merchants Bank completed the RMB position transfer business from Hongkong Wing Lung Bank to Shenzhen Branch of Wing Lung Bank. This is the world's first interbank cross-border RMB clearing business based on blockchain technology
in addition, according to the white paper 2016 on China's blockchain technology and application development issued by the Ministry of instry and information technology of China, the application of blockchain has been extended to medical and health, ecation, charity, social management and other fields. Taking the cultural instry as an example, the low cost of reproction, the high cost of safeguarding rights, and the difficulty of providing evidence make the protection of intellectual property rights a pain point for the instry. With blockchain, the proction, dissemination and transaction records of cultural procts are true, transparent and reliable, and the problem can be solved
Zhang Xiaorong said that blockchain technology has solved two major problems in the era of Digital Economy: one is the visible flow direction, and the other is zero trust cost. In the past, the circulation of physical paper money was invisible, but the flow of all digital assets had a "chain" to check. Yang Yanchao, a researcher at the intellectual property center of the Chinese Academy of Social Sciences, also believes that the biggest advantage of blockchain is that it has truly completed the credit construction in an anonymous society, bringing new opportunities to many fields, thus making various innovative applications possible
there is a long way to go in the future development
in terms of technology promotion, there is no big barrier to blockchain, which has been confirmed in the global practice of bitcoin, and its main resistance comes from the obstacles in concept and implementation
"on the one hand, the society may be very concerned about the" naked "state in the blockchain. Blockchain has built a "Skynet" for the commercial society. The company's economic activities are all recorded, so there is no secret to speak of. In this way, some business strategies may not be implemented under the blockchain. "
"on the other hand, the current legal system lags behind the development of information technology, so how to put the emerging blockchain technology under the legal supervision needs to be studied." Duan Yongchao said
the core of blockchain is decentralization, which will have an impact on the long-standing central management model. In addition to the law, how to establish a regulatory environment that can promote the application of blockchain technology, so that the technology can benefit the society and not be used to do evil, is also an urgent problem to be solved.

2. The domestic blockchain technology has put forward the concept from the beginning, and now it has been applied to the actual business scenarios, such as the vonetracer traceability system of wanglian technology, and their blockchain Traceability Technology has been applied to the actual agricultural procts.
