Challenges faced

From a practical perspective, most of the applications of blockchain technology in commercial banks are still being conceived and tested. There is still a long way to go before it can be used in life and production, and it also faces many difficulties in gaining recognition from regulatory authorities and the market. The main ones are:

1. Restricted by current concepts, systems, and laws. The characteristics of decentralization, self-management, and collective maintenance of blockchain have subverted people's production and lifestyle, diluted the concept of state and supervision, and impacted existing legal arrangements. For these, the entire world completely lacks theoretical preparation and institutional discussion. even blocksBitcoin, the most mature blockchain application, has different attitudes in different countries, which inevitably hinders the application and development of blockchain technology. There is obviously still a long way to go to solve this kind of problem.

2. At the technical level, blockchain still needs breakthrough progress. Blockchain applications are still in the initial development stage of the laboratory, and there are no mature products that are intuitive and available. Compared with Internet technology, people can use specific applications such as browsers and APPs to browse, transmit, exchange and apply information. However, blockchain obviously lacks such breakthrough applications and faces high technical barriers.

Industry Blockchain: Multiple pre-selected ones specified within a certain groupThe node is the bookkeeper, and the generation of each block is jointly decided by all pre-selected nodes (the pre-selected nodes participate in the consensus process). Other access nodes can participate in transactions, but do not participate in the accounting process (it is essentially still managed accounting, but changes Into distributed accounting, the number of pre-selected nodes and how to determine the bookkeeper of each block have become the main risk points of the blockchain), and anyone else can conduct limited queries through the open API of the blockchain. Private blockchain: only uses the general ledger technology of the blockchain for accounting. It can be a company or an individual, with exclusive write permission to the blockchain.
