With the development of information technology and cloud computing,data sharing has become an important part of scientific research.In traditional data sharing,data is stored on a third-party storage platform,which causes the owner to lose control of the data.As a result,there are issues of intentional data leakage and tampering by third parties,and the private information contained in the data may lead to more significant issues.Furthermore,data is frequently maintained on multiple storage platforms,posing significant hurdles in terms of enlisting multiple parties to engage in data sharing while maintaining consistency.In this work,we propose a new architecture for applying blockchains to data sharing and achieve efficient and reliable data sharing among heterogeneous blockchains.We design a new data sharing transaction mechanism based on the system architecture to protect the security of the raw data and the processing process.We also design and implement a hybrid concurrency control protocol to overcome issues caused by the large differences in blockchain performance in our system and to improve the success rate of data sharing transactions.We took Ethereum and Hyperledger Fabric as examples to conduct cross-blockchain data sharing experiments.The results show that our system achieves data sharing across heterogeneous blockchains with reasonable performance and has high scalability.
