The invention discloses a cross-chain data sharing method, system and device and a readable storage medium. The method comprises the steps that a main block chain node in a cross-chain platform receives first shared transaction information sent by a source block chain; verifying the first shared transaction information in the trusted execution environment; after all block chain nodes in a preset range in the cross-chain platform pass verification, packaging the second identifier of the source block chain, the first identifier and the target shared data into second shared transaction information; and the second shared transaction information is sent to the target block chain, so that the data can be shared between the two block chains, and further, due to the deployment of the trusted execution environment, the data sharing between the block chains is safer, and the data is prevented from being leaked.
Description
technical field [0001] The present application relates to the technical field of blockchain, in particular to a method, system, device and readable storage medium for cross-chain data sharing. Background technique [0002] Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. It is essentially a decentralized database. Blockchains can be divided into public blockchains, joint blockchains, and private blockchains. There may be data sharing and even interaction requirements between different blockchains. [0003] During the long-term research and development process, the applicant of this application found that there is isolation between blockchains, and data sharing cannot be performed, which limits the flow of data between blockchains, and how to ensure data security in the process of data interaction Sexuality is also a key issue that needs to be paid atten...
