The present invention provides a consortium chain node data transmission method, device, and storage medium. The method includes: in response to sending first data to a second consortium chain node located in a second local area network of the current consortium chain, and generating a second consortium chain node according to the first data. An encrypted message; generate the first parachain transaction of the first parachain including the first encrypted information, and send the first parachain transaction to the first parachain node or the first main chain node of the first parachain for the The first parachain transaction is recorded on the main chain for the second parachain node of the first parachain to synchronize the first parachain transaction from the second main chain node and record the first parachain transaction on the first parachain, The second consortium chain node requests the first parachain transaction from the second parachain node, and decrypts the first encrypted information to obtain the first data after receiving the returned first parachain transaction. This application makes the data transmission between different consortium chain nodes of the same consortium chain in different local area networks reliable and efficient.
Description
technical field [0001] The present application relates to the technical fields of blockchain and the like, and in particular to a method, device and storage medium for data transmission of a consortium chain node. Background technique [0002] The deployment nodes of the same consortium chain require interoperability between networks. If enterprise A deploys consortium chain node A, and enterprise B deploys consortium chain node B, enterprise A and enterprise B deploy node A and node B in their respective local area networks for security reasons. To enable node A and node B to transmit data to each other, the first method is to use a centralized server to complete NAT penetration, and the second method is to use relay interconnection technology forwarded by intermediate nodes. [0003] The first method cannot guarantee the reliability of the data of the centralized server; the second method takes a long time and the data transmission efficiency is low. SUMMARY OF THE INVE...
