Problems solved by technology

In the alliance chain system, such a design has the following problems: there is a single point of failure problem, if the central organization fails, new nodes cannot join, and the certificate system will not be maintained; there is a problem of evil, this organization can distribute certificates to malicious nodes at will , which is harmful to the blockchain system

Embodiment Construction

[0021] The present invention will be described in detail below according to the accompanying drawings and preferred embodiments, and the purpose and effect of the present invention will become clearer. The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] Such as Figure 1-2 As shown, a management method of blockchain distributed certificates based on smart contracts is characterized in that the basic structure of the distributed certificate system in this method is that each node of the blockchain system will provide certificates for all other nodes, All other nodes use this certificate to connect to the node, and each node corresponds to a user account with management rights. The management method specifically includes the following steps:

Abstract

The invention discloses a block chain distributed certificate management method based on intelligent contract. In the system start-up stage, each system node corresponds to a user with system authority, and all users provide their own addresses to initialize the distributed certificate management intelligent contract. The new node should join the system, or the system should delete a node, and putforward the corresponding proposal; after the smart contract checks the validity of the proposal, the proposed event is forwarded to all user clients with system privileges; after receiving the proposal event, the client notifies the user to vote, and the user votes and feeds back to the intelligent contract. When a sufficient number of consents are gathered for a smart contract, the proposal ispassed and applied, and the system issues or revokes the certificate. The invention solves the centralization problem of the traditional certificate system, solves the problem of a single point of failure, and improves the safety.

Description

technical field [0001] The present invention relates to smart contracts and certificate authentication and authorization technologies, in particular to a management method for blockchain distributed certificates based on smart contracts. Background technique [0002] Smart contracts are an idea proposed by Nick Szabo in the 1990s, almost at the same age as the Internet. Due to the lack of a trusted execution environment, smart contracts have not been applied to the actual industry. Since the birth of Bitcoin, people have realized that the underlying technology of Bitcoin, the blockchain, can inherently provide a trusted execution environment for smart contracts. Smart contracts are assembly language programmed on the blockchain. Usually people don't write the bytecode themselves, but compile it from a higher level language. [0003] An e-commerce certification authority is an authoritative organization responsible for issuing and managing digital certificates, and as a tru...
