Blockchain-based cross-chain interconnection method, device and system

Abstract

The invention provides a blockchain-based cross-chain interconnection method, a blockchain-based cross-chain interconnection system, computer equipment and a computer readable storage medium, and relates to the technical field of information processing. The system comprises a cross-chain gateway node and a plurality of service chains, each service chain comprises an authority management node, a gateway node and a plurality of verification nodes, and the gateway node in the plurality of service chains and the cross-chain gateway node form a cross-chain gateway; and the cross-chain gateway is used for realizing message format standardization and a cross-chain conversion protocol among the plurality of service chains so as to promote adaptation and forwarding of cross-chain messages, support error processing of request message timeout during cross-chain interconnection and finally realize mutual access and intercommunication of cross-chain data. Mutual access among the alliance chains of a plurality of different block chain technologies is achieved by introducing the bridging gateway chain, the problem of information island among a plurality of block chain systems is solved, and application and popularization of the block chain technology can be accelerated.

Description

technical field [0001] The present invention relates to the field of information processing technology, in particular to information processing technology involving blockchain, specifically a blockchain-based cross-chain interconnection method, a blockchain-based cross-chain interconnection system, computer equipment and computer readable storage media. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] The blockchain system encrypts and hashes data and data operation records through cryptographic methods, thereby forming an open, transparent, non-tamperable, and traceable distributed database accounting system. This technology can be widely used in payment and settlement, deposit and collection of evidence, value transfer, supply chain finance, user credit investigation, ...

AI Technical Summary

Problems solved by technology

Different blockchain alliance chains take into account the actual situation of the blockchain system's own performance capacity, audit supervision, data isolation, security and privacy, etc., the bottom layer of the system may use different blockchain technologies, such as Ethereum, Ripple, Fabric Waiting for technical implementation, it is difficult to interconnect and access between different blockchain consortium chains, so that there is network isolation between multiple blockchain consortium chains, and network isolation hinders the connection between multiple blockchain consortium chains. The collaborative operation ability of the blockchain greatly limits the ability and promotion of the blockchain

[0005] In the prior art, data transmission and access between two blockchains are generally achieved through relaying, but the relay node itself is also a centralized node, and one of the interactive data leaves the blockchain and then enters another area. The process of blockchain, this operation reduces the decentralization and tamper-proof features of blockchain technology, and also affects the trust and value transfer between chains
