As academic research becomes more and more international, close cooperation between different research institutions has become a key factor in promoting the development of science and technology. Research teams and institutions in different countries urgently need an effective and secure online platform for collaboration and data sharing. To solve the above problems, this paper proposes a scientific research data storage and sharing scheme based on Hyperledger Fabric, which combines blockchain technology with interplanetary file system and effectively relieves the storage pressure of blockchain network. The multi-channel architecture is designed to protect scientific research data based on physical isolation of different channel ledger data. In addition, through proxy re-encryption, a fine-grained permission control scheme for user data is designed and implemented. The data receiver can decrypt the ciphertext without obtaining the key of the sender. In this way, the private key and plaintext of the sender are not leaked during data sharing, which improves data privacy and achieves data sharing. Finally, Docker technology was used to build a test environment, and the system was tested for function and performance, which verified the feasibility of the scheme system.
