Shanghai, April 18 (xinhua) -- for volunteer zeng, even if he only donated 10 masks, he would like to know where to go. In this Blockchain app, two bottles of disinfectant and a box of instant noodles can be linked and kept forever.

Reporters see, this small program from the surface and the ordinary application is no different, but the background information organization and storage has undergone a huge change. Each donation has a unique string, also known as a hash. The hash can be likened to this unique "fingerprint" of the record: you can quickly trace the flow of material to whether it was fraudulent or not, and if tampering occurs, it can be recorded.

According to incomplete statistics, up to now, about 20 blockchain-related applications have been launched to assist epidemic prevention and control, covering such scenarios as identity management, information confirmation, supply chain finance, and information collection and confirmation.

As an important part of the new infrastructure, as the technology continues to mature, blockchain is gradually moving from the model stage to the actual stage. In many fields such as supply chain management and whole-life cycle management of buildings, blockchain can improve the efficiency of the real economy.

Its application field can be roughly summarized as: if need to trace, can block chain. Whether it is the full recording of drawings in the construction process, safety backtracking, or data security in the fields of finance and credit investigation, even if it is the "small commitment" between husband and wife, there is the need for traceability, there is the possibility of "chain".

"A large industrial production enterprise may have more than 2 million suppliers at multiple levels, and the whole supply chain cannot penetrate in the past." Yang guang, research director of Shanghai blockchain research institute, said that under the impact of the epidemic, due to the different progress of the resumption of work, the upstream and downstream industry chain began to appear urgent adjustments. In the past, enterprises could only rely on their interpersonal diffusion. Supply chain management was like relying on the experience of old drivers and paper map navigation. The whole-process management of the supply chain based on the block chain technology is just like the current electronic map navigation, which not only shows the new roads in time, but also shows where the traffic jam is.

Shanghai tretu blockchain research institute formally settled in the binjiang district of xuhui, Shanghai in January this year. It is a new research and development institution focusing on the underlying infrastructure of blockchain. It is building the "main network" of blockchain, hoping to provide a safe and reliable blockchain "Windows" system for all users. During the epidemic, the xuhui district science and technology commission quickly implemented office space, talent apartment and epidemic prevention materials for the institute.

Xuhui district science and technology commission, said the chain blocks, artificial intelligence, cloud computing, 5 g is infrastructure of digital economy, will continue to from aspects of the project, talents, business services support "hardcore enterprises" development, speed up the use of new technology such as block chain, activate the supply chain, through the industrial chain, to drive innovation chain, speed up the economic development of the online new opportunities into the kinetic energy of the regional economic development of new high quality.

"Visually speaking, our blockchain technology is moving from the 2G era to the 5G era." Wu Ming, chief technology officer of the blockchain institute, said that in the past blockchain infrastructure had poor performance. It could only handle dozens of transactions per second, and the confirmation time for a transaction was more than 10 minutes. By analogy, the peak of "double 11" on taobao is more than 500,000 transactions per second, and the daily transaction volume of credit card is also thousands of transactions per second. Therefore, it is urgent to build infrastructure, update technology and consolidate.

In 2020, all kinds of policies on blockchain from the central government to the local government have been significantly accelerated. Blockchain has been listed as one of the key construction projects in hunan and jiangxi provinces. The application scenarios include supply chain finance, intelligent government and many other fields, and the total investment amount of the project is billions of yuan.

Digital social governance innovation and soft and hard infrastructure construction have become the important needs of economic and social development. At the beginning of this year, the whole land parcel in the west bund city of xuhui district in Shanghai was sold to the financial technology fields such as blockchain.

"Besides lujiazui, Shanghai should also have an emerging financial sector." According to fang shizhong, mayor of Shanghai's xuhui district, London has canary wharf as well as the city, and the distance between the two is 6km, which happens to be the distance between the west bund city and lujiazui. Led by fintech, the west bund city will strive to build a global digital currency center and become a new growth pole of Shanghai's international financial center.
