Transaction data updating method and system based on block chain world state, and storage medium

Abstract

The invention provides a block chain world state-based transaction data updating method, a storage medium and a system, wherein block chain has a plurality of nodes which form a network, and the method comprises the following steps: obtaining transaction information in a block; analyzing at least two related nodes related to the transaction according to the transaction information in the block; searching adjacent nodes which are correspondingly adjacent to each related node; obtaining the number of adjacent nodes corresponding to each related node and address information of each adjacent node; for each related node, performing data updating according to the transaction information in the block to obtain transaction data; dividing the transaction data into a plurality of data segments according to the number of adjacent nodes; transmitting each data segment to each corresponding adjacent node; and transmitting the address information of each corresponding adjacent node to other related nodes related to the transaction, so that the other related nodes can respectively acquire the data segments from each corresponding adjacent node according to the address information after the transaction in the block is finished to perform data updating.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method, storage medium and system for updating transaction data based on the state of the blockchain world. Background technique [0002] The blockchain is formed into a network in the form of nodes. All nodes start from the same initial state and sequentially execute the intra-block transactions that have been reached by each node, thereby driving the state of each node to follow the same operation sequence (add, delete, modify ) is constantly changing, so that all nodes are in the same state after executing the same transaction in the block. This state is called the world state. [0003] Each node of the blockchain integrates a KV database (Key-Value database) to store various information, such as account balances, smart contract bytecodes, custom data for each smart contract, and configuration parameters of the blockchain Wait. After the blockchain executes...

Problems solved by technology

However, if there are multiple nodes in the blockchain that execute multiple intra-block transactions in a short period of time, too frequent intra-block transactions will lead to excessive data transmission pressure on the blockchain network and excessive data storage pressure on nodes. Large, making it difficult for multiple nodes involved in transactions to be in a consistent world state
