Blockchain CA integration

1. Generally speaking, blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer
among them, the data layer encapsulates the underlying data block and related data encryption and timestamp technologies; The network layer includes distributed networking mechanism, data transmission mechanism and data verification mechanism; The consensus layer mainly encapsulates all kinds of consensus algorithms of network nodes; The incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; The contract layer mainly encapsulates all kinds of scripts, algorithms and smart contracts, which is the basis of the programmable characteristics of blockchain; The application layer encapsulates various application scenarios and cases of blockchain. In this model, chain block structure based on timestamp, consensus mechanism of distributed nodes, economic incentive based on consensus computing power and flexible and programmable smart contract are the most representative innovations of blockchain technology.

2. Now some domestic enterprises have applied blockchain technology to the actual instry. For example, wangchain technology has applied blockchain to financial services, health care, IP right, Internet of things, sharing economy, communication, ecation,
social management, charity, public welfare, culture and entertainment, etc

3. It's hammered out, and it's on the 60th floor. How can you get to the 108th floor and still don't know how to get the sage's stone?

It's one thing. A reliable electronic signature has the same legal effect as a handwritten signature or seal. The valid digital certificate issued by the legal electronic certification authority (CA) can meet the requirements of Article 1, Article 3 and Article 4 according to the four provisions of the electronic signature law for reliable electronic signature. However, to meet the requirements of the second article, it needs the real-time interconnection support of the whole reliable electronic signature system

general electronic signature refers to the use of digital certificate issued by Ca organization for signature. However, the valid digital certificate issued by the legal electronic certification authority (CA) can generally meet the requirements of Article 1, Article 3 and Article 4. However, to meet the requirements of the second article, it needs the real-time interconnection support of the whole reliable electronic signature system< br />
