2. Blockchain is an innovative application mode of computer technology such as distributed data storage, point-to-point transmission, knowledge mechanism and encryption algorithm in the Internet era. In recent years, the development and application of blockchain is of great significance to technological innovation and industrial revolution. This experience introduces the relevant knowledge of blockchain technology.
3. Blockchain is a distributed ledger, which can contain financial and/or non-financial transactions. Replicate (distribute) on multiple systems almost in real time through peer-to-peer networks.

There is a mechanism to make it.
