The invention provides an alliance chain node data transmission method and device and a storage medium, and the method comprises the steps: responding to the transmission of first data to a second alliance chain node, located in a second local area network, of a current alliance chain, and generating first encryption information according to the first data; generating a first parallel chain transaction including a first parallel chain of the first encrypted information, sending the first parallel chain transaction to the first parallel chain node or the first main chain node of the first parallel chain, and recording the first parallel chain transaction on the main chain, so that the second parallel chain node of the first parallel chain synchronizes the first parallel chain transaction from the second main chain node and records the first parallel chain transaction on the first parallel chain; and sending the first encrypted information to a second alliance chain node, so that the second alliance chain node requests a first parallel chain transaction from a second parallel chain node, and decrypting the first encrypted information to obtain first data after receiving the returnedfirst parallel chain transaction. According to the invention, data transmission between different alliance chain nodes of the same alliance chain in different local area networks is reliable and efficient.
Description
technical field [0001] This application relates to technical fields such as block chains, and in particular to a data transmission method, device and storage medium for consortium chain nodes. Background technique [0002] The deployment nodes of the same consortium chain need intercommunication between networks. If enterprise A deploys node A of the alliance chain, and enterprise B deploys node B of the alliance chain, enterprise A and enterprise B deploy node A and node B in their respective LANs for security and other reasons. To make node A and node B transfer 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. Contents of the invention [0004] In vi...
