Cross-chain service processing method and device based on relay chain, equipment, storage medium

Abstract

The application relates to a relay chain-based cross-chain service processing method and device, equipment and a storage medium, and belongs to the field of blockchains. The method comprises the following steps: obtaining a first cross-chain transaction request of a cross-chain transaction sent by a source chain, wherein the first cross-chain transaction request carries the data of the cross-chain transaction, a transaction type identifier and a target chain identifier; distributing the cross-chain transaction data to a cross-chain processing channel corresponding to the transaction type identifier in a relay chain according to the transaction type identifier, performing operation and obtaining an operation result; performing consensus processing on the cross-chain transaction according to the operation result; sending a second cross-chain transaction request to a target chain corresponding to the target chain identifier, wherein the second cross-chain transaction request carries the data of the cross-chain transaction and a transaction identifier; and sending a processing result of the second cross-chain transaction request obtained by the target chain to the source chain. The application parallelly processes the cross-chain transaction by distributing the cross-chain transaction to different cross-chain processing channels, realizes the concurrency of intrachain transactions on the relay chain service, and improves the processing performance of the cross-chain transaction.
