Data processing method and device, node equipment and computer storage medium

Abstract

The embodiment of the invention provides a data processing method and device, node equipment and a computer storage medium. The method comprises the following steps: a first node acquires a transaction hash list in a transaction pool, writes the transaction hash list into the block body of the alternative block, and broadcasts the alternative block in a block chain network, so that a second node of the block chain network uses locally cached transaction data to verify a transaction hash included in the transaction hash list and obtains a verification result, the first node receives a target transaction hash sent by the second node according to the verification result, wherein the target transaction hash is a transaction hash corresponding to transaction data which is not cached locally bya consensus node in the transaction hash included in the transaction hash list; therefore, the first node can send the target transaction data corresponding to the target transaction hash to the second node, so that the second node verifies the target transaction hash by using the target transaction data, the network resource consumption can be reduced, and the consensus efficiency and the servicethroughput are improved.

Description

Technical field [0001] The present invention relates to the field of computer technology, in particular to a data processing method, device, node equipment and computer storage medium. Background technique [0002] At present, in the consensus block generation stage of each round of the blockchain network, transaction data is packaged into the block body of the block. Because the amount of transaction data may be relatively large, the number is also large, and the size of each block is Restriction. This obviously limits the number of packaged transactions and reduces the throughput of transactions. At the same time, due to the asynchronous execution of transaction pools and consensus verification, this will waste network resources. It can be seen that how to reduce network resource consumption during block generation and consensus verification and improve consensus efficiency and business throughput has become an urgent problem to be solved. Summary of the invention [0003] The ...
