Parallel Chain Cross-Chain Transaction Method, Device and Storage Medium

摘要

The present invention provides a parallel chain cross-chain transaction method, a device and a storage medium. The method includes: receiving a first transaction group; wherein the first transaction group comprising a first transaction on a main chain and a second transaction on a first parallel chain, and the first transaction group being packaged and generated by a matchmaking server or a wallet terminal; confirming an executability of the first transaction and recording the first transaction group onto the main chain, so that each node of the first parallel chain acquires and executes, from a corresponding main chain node, the second transaction, and each verification node of the first parallel chain packages first block information of a first block, wherein the first block information comprising an execution result of the second transaction; receiving the first block information sent by each corresponding verification node of the first parallel chain, and recording same onto the main chain to perform consensus on the first block; and confirming, according to the first block information of the first block passing through the consensus, whether the second transaction has been executed successfully: if so, completing the execution of the first transaction. The present invention provides a cross-chain transaction mechanism between a main chain and a parallel chain.
