A blockchain consistency maintenance method and device

Abstract

The invention discloses a block chain consistency maintenance method and device. This method is: for each node Pi in the decentralized system; when node Pi receives a new block, it verifies whether the block satisfies the workload, and if so, then each of the blocks to be completed The state transition of the block is voted and broadcast, and then it is verified whether it satisfies the legality verification. If each state transition to be completed in the block satisfies the legality verification, and the block length of the block is greater than the length of the local blockchain , add this block as a new block to the current blockchain. The present invention introduces a new verification layer on top of the block chain, the block is generated by the underlying block chain, and the verification of the block is completed by the verification layer, and the status change of the block chain needs to go through this verification layer consent, so that the present invention enables the blockchain-based decentralized application to have state verification.

Description

technical field [0001] The invention relates to a block chain consistency maintenance method and device, belonging to the technical field of network communication. Background technique [0002] Blockchain maintains a public ledger in an unreliable distributed environment that is maintained and extended by a series of anonymous participants. In recent years, blockchain networks have attracted more and more attention from engineers, academics and investors. With a large amount of capital investment, the blockchain has been rapidly deployed and has become a public infrastructure. [0003] Since the blockchain does not have a trusted central node, this makes the design and implementation of a decentralized domain name system, public key certificate system and decentralized file storage a reality. [0004] However, the current blockchain-based applications need to maintain global consistency in an insecure distributed environment. Every specific operation involves state transit...

Problems solved by technology

[0004] However, the current blockchain-based applications need to maintain global consistency in an insecure distributed environment. Every specific operation involves state transitions, but the current blockchain technology does not provide a legal basis for state transitions. Therefore, the consistency maintenance of the blockchain cannot be achieved, which will lead to various problems:

[0005] 1) Taking the decentralized domain name system as an example, when there is a conflict in domain name registration, that is, an authoritative organization and an individual apply for an authoritative domain name at the same time, the ownership of the authoritative domain name is determined by a single node that has the opportunity to write a block. Once a single node An error will cause this authoritative domain name to be registered by an individual and cannot be changed

[0006] 2) In the decentralized file storage system, once a resource with copyright issues or illegal resources is successfully uploaded, it is difficult for others to delete it except the uploader itself

Crawler software can only detect which resources are illegal, but cannot prevent the upload of resources, and the introduction of third-party detection methods will bring more problems
