A 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 includes a cross-chain gateway node and a plurality of business chains, each of which includes an authority management node, a gateway node, and multiple verification nodes, and the gateway nodes in the multiple business chains and the cross-chain gateway nodes form a cross-chain Chain gateway; the cross-chain gateway is used to realize the message format standardization and cross-chain conversion protocol between the multiple business chains, so as to promote the adaptation and forwarding of cross-chain messages, and support the request for cross-chain interconnection The error handling of message timeout finally realizes the mutual access and intercommunication of cross-chain data. The present invention implements mutual access between alliance chains of multiple different blockchain technologies by introducing a bridging gateway chain, solves the problem of isolated information islands between multiple blockchain systems, and can accelerate the application and promotion of blockchain technology.

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
