The data layer, network layer, *** knowledge layer, incentive layer, contract layer and application layer need to be established.

1, the data layer encapsulates the underlying data blocks as well as the relevant data encryption and timestamps and other basic data and basic algorithms;

2, the network layer includes the distributed networking mechanism, data propagation mechanism, and data validation mechanism, etc.

3, the *** knowledge layer mainly encapsulates all kinds of *** knowledge algorithms of the network nodes;

4, the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives;

5. The contract layer mainly encapsulates all kinds of scripts, algorithms and smart contracts, which is the basis of the programmable characteristics of the blockchain;

6. The application layer encapsulates various application scenarios and cases of the blockchain.

General Secretary Xi Jinping emphasized in the 18th collective study of the Political Bureau of the Central Committee that "the blockchain as an important breakthrough in independent innovation of core technology" and "accelerate the promotion of blockchain technology and industrial innovation and development".

The CPC Central Committee's forward-looking judgment has brought blockchain into the public's view and made it a point of concern for financial capital, the real economy and public opinion***.

From network power to big data, from media convergence to blockchain, the Politburo collective study aimed at the forefront of technological change, showing the direction of the CPC Central Committee's grasp of power, forward-looking judgment and future foresight, leading China's industrial change and the pace of economic transformation. The Politburo's collective study, specifically emphasizing "blockchain", opens up the imagination for the development and application of blockchain.

From a scientific and technological point of view, blockchain involves many scientific and technological issues such as mathematics, cryptography, Internet and computer programming. From the application perspective, in simple terms, blockchain is a distributed **** enjoyment ledger and database with the characteristics of decentralization, non-tampering, leaving traces of the whole process, traceability, collective maintenance, openness and transparency, and so on.

These features ensure the "honesty" and "transparency" of blockchain, and lay the foundation for blockchain to create trust. The rich application scenarios of blockchain are basically based on the ability of blockchain to solve the problem of information asymmetry, and to realize the collaborative trust and concerted action between multiple subjects.
