Problems solved by technology
[0004] In the process of implementing the present invention, the inventor found that the existing sharding method has at least the following problems: using the architecture of the master-slave chain, although the blocks on each sharding chain do not affect each other, this will lead to fragmentation. The block generation on the chain and the final confirmation of its blocks are asynchronous, and the blocks on the shard chain have the risk of rollback
The architecture of multiple shard executors controlled by the block generation module can speed up the execution speed of a block through multiple shard executors in parallel, but because of the different transaction numbers and transaction complexity on each shard, it may lead to During the execution cycle of a block, some shard executors are idle, while some shards are always busy, and there is a phenomenon of waiting between each other, resulting in low transaction efficiency

The invention relates to the technical field of block chains, and discloses a transaction asynchronous execution method and system in a block chain and related equipment, and the method comprises the steps: sending a transaction block in a to-be-sent cache queue to each lower executor based on a preset triggering mechanism, and when an acknowledgement character ACK for the transaction block sent by the lower executor is received, taking the transaction block corresponding to the acknowledgement character ACK as a first transaction block, moving the first transaction block in a to-be-sent cache queue into a to-be-received cache queue; if an execution result sent by a lower-layer actuator is received, obtaining the transaction block contained in the execution result as a second transaction block, and executing deletion processing on a first transaction block with the same serial number as the second transaction block in the to-be-received cache queue, and transmitting an acknowledgement character ACK of an execution result to the lower layer executor. According to the invention, the transaction asynchronous execution efficiency is improved.
Description
technical field [0001] The present invention relates to the technical field of block chains, in particular to a method, system and related equipment for asynchronous execution of transactions in block chains. Background technique [0002] In a blockchain network, sharding is used to break down transactions into shards and distribute them across the network so that each network node does not have to download and save the entire blockchain state. Through parallelization, sharding technology can significantly increase transaction processing speed. [0003] In the current state sharding or execution sharding solutions, the architecture of the master-slave chain is mainly adopted. Each shard chain produces its own block and then anchors to the main chain to realize the execution of the main chain block and the shard block. Decoupling. In addition, there are some block generation modules that control the architecture of multiple shard executors. The general execution implementat...
