Abstract

One or more embodiments of the invention provide a Hyperledger Fabric-based basic cross-chain method, device and equipment, and a medium. A Hyperledger Fabric-based block chain system comprises a first service sub-chain and a second service sub-chain; the method is applied to a client corresponding to a service provider, and comprises the following steps: acquiring a data identifier of demand data corresponding to a data demand side; constructing a cross-chain copy transaction based on the data identifier; issuing the cross-chain copy transaction to the second service sub-chain, and triggering a Peer node in the second service sub-chain to respond to the cross-chain copy transaction; calling a second chain code deployed in the second service sub-chain, and executing cross-chain calling logic in the second chain code; calling a first chain code deployed in the first service sub-chain in a cross-chain manner, and executing data acquisition logic in the first chain code; and obtaining demand data corresponding to the data identifier and stored in the first service sub-chain, and storing the demand data in the second service sub-chain, so that a client corresponding to the data demander obtains the demand data from the second service sub-chain.

Description

technical field [0001] One or more embodiments of this specification relate to the field of computer application technology, and in particular to a basic cross-chain method, device, device and medium based on Hyperledger Fabric. Background technique [0002] In related technologies, in the blockchain system based on Hyperledger Fabric, channels are usually divided according to the organizations actually participating in the business, and organizations participating in the same business are added to the same channel. However, for a certain channel, the data stored in the channel is visible to all organizations in the channel. Therefore, the protection granularity of data privacy is relatively coarse, and the data security is low. SUMMARY OF THE INVENTION [0003] This specification proposes a basic cross-chain method based on Hyperledger Fabric. The blockchain system based on Hyperledger Fabric includes several sub-chains corresponding to several channels; the several sub-c...
