Cross-Chain Technology of Consortium Blockchain Based on Identity Authentication

With consortium blockchain becoming the mainstream form of blockchain applied to various industries, the proportion of nonasset data in blockchain applications is gradually increasing. However, there is currently no cross-chain solution for nonasset data. The aim of this study is to explore the cross-chain problem of nonasset data and design a cross-chain solution that is suitable for the application scenarios of consortium blockchains. We achieved cross-chain identity authentication through an integrated distributed trust model. We then proposed cross-chain anchor nodes as alternatives to traditional routing, eliminating third-party Relay risks while ensuring secure information transmission through smart contracts. Finally, on the basis of ensuring the timeliness and reliability of data transmission, combined with the consortium blockchain organizational structure, cross-chain technology is more in line with the characteristics of data element circulation. This study provides an effective and secure solution for cross-chain interaction and application data flow in consortium blockchains through comprehensive smart contract protection mechanisms and rigorous access controls. The proposed approach is expected to promote the safe application and development of consortium blockchain technology in various industries.
