Block chain transaction method and device, terminal equipment and computer readable storage medium

Abstract

The invention provides a block chain transaction method and device, terminal equipment and a computer readable storage medium, and the method comprises the steps: packaging a cross-chain transaction transaction into a cross-chain transaction event if a transaction start chain initiates the cross-chain transaction transaction, and transmitting the cross-chain transaction event to a preset relay chain; obtaining a first block height of a target block in the relay chain, wherein the target block is a block for processing a cross-chain transaction event in the relay chain; and processing the cross-chain transaction event according to the first block height. According to the block chain transaction method provided by the invention, the relay chain can be used as a processing bridge of the transaction starting chain and the transaction destination chain, so that the problem that other transactions cannot be processed due to overtime processing of the current transaction when the transaction starting chain and the transaction destination chain process a plurality of transactions is avoided. Meanwhile, according to the block height for processing the current transaction in the relay chain, timeout or non-timeout control is carried out on the current transaction, timeout cross-chain transactions can be returned to the transaction starting chain, and the timeout rate of the transaction is reduced.

Description

technical field

[0001] The present application relates to the field of blockchain, in particular to a blockchain transaction method, device, terminal equipment, and computer-readable storage medium. Background technique

[0002] In the cross-chain transaction scenario of the blockchain, after the source chain (the starting chain of the transaction or the transaction initiation chain) initiates a cross-chain transaction for a business, it needs to wait for the destination chain (the receiving chain of the transaction) to execute the cross-chain transaction After returning the receipt to continue the business. If the destination chain TPS (Transactions Per Second, the number of transaction processing per second) is low, or the network between the source chain and the destination chain fails, it will cause the source link to receive the receipt of cross-chain transactions from the destination chain. Slow, affecting the normal operation of the business on the source chain, whic...
