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. And the public chain consensus node election mechanism is realized based on PageRank. Then, according to the characteristics of a nonsingle chain structure in the process of data flow, a data retrieval mechanism based on a Bloom filter is designed, and the cross-domain traceability algorithm is given. Finally, the safety and effectiveness of the traceability mechanism are verified by security evaluation and performance analysis.
