Abstract With the application and development of blockchain technology, many problems faced by blockchain traceability are gradually exposed. Such as cross-chain information collaboration, data separation and storage, multi-system, multi-security domain collaboration, etc. To solve these problems, it is proposed to construct trust domains based on federated chains. The public chain is used as the authorization chain to build a cross-domain data traceability mechanism applicable to multi-domain collaboration. First, the architecture of the blockchain cross-domain model is designed. Combined with the data access strategy and the decision mechanism, the open and transparent judgment of cross-domain permission and cross-domain identity authentication is realized.… More >
