摘　　要：To address the challenges of low credibility,difficult data sharing,and regulatory supervision issues involving electronic evidence storage in the judicial preservation process,this paper proposes a blockchain-based judicial evidence preservation scheme.The scheme utilizes the characteristics of blockchain’s immutability to achieve credible forensics of electronic evidence on the chain and employs the decentralized storage of the interplanetary file system for secure and efficient off-chain storage.Simultaneously,it resolves the problem of declining throughput due to limited block capacity.Additionally,it leverages smart contract technology to encompass major aspects of the judicial process,including user case registration,authority management,judicial evidence uploading and downloading,case data sharing,partial disclosure of case information,and regulatory review.Simulation experiments demonstrate that the scheme significantly improves throughput and stability.Performance tests indicate that the transfer speed of the interplanetary file system can meet the data-sharing needs of judicial organizations.
