blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

if such technology wants to be put into application, the biggest problem is the "Impossible Triangle problem"

that is, scalability, decentralization and security cannot be achieved at the same time, and only two of them can be achieved

most of the existing public chain projects in the market are difficult to put into use on a large scale

2. This needs to be created with the help of the platform
the hypervessel platform developed by IBM China Research Institute provides a blockchain development and testing environment for blockchain enthusiasts and developers. Through this platform, users can create a multi node blockchain based on hyperledger fabric free of charge and quickly, and play smart contracts on their own chains
of course, decent, a foreign decentralized content sharing platform, can also be created.

3. Since the server is under the control of the United States, is it really safe for China to engage in digital currency? This issue of security is assessed by the state, which may not need your consideration. Moreover, I think the state has its own plan to develop financial currency, especially digital currency

Bitcoin is a kind of electronic payment currency. You can understand it as the RMB on the Internet

blockchain technology is the technology to develop this kind of currency. generally speaking, it is the blockchain technology that invented bitcoin

why must it be blockchain technology instead of other technologies, because currency has its particularity and sensitivity. It plays a special role in social proction. For example, we require money to have stable value, decentralization, liquidity and credit system. Blockchain technology solves these problems well< br />
