Abstract

A state data restoration method for a blockchain, executed by a computer device that maintains a first node in a blockchain system. The method comprises: when a proposal message broadcast by a second node in the blockchain system is received, acquiring state data maintained by the first node itself, wherein the proposal message indicates a transaction task, result information for the transaction task, and a block identifier (302); executing the transaction task in the proposal message on the basis of the state data to obtain result information (304); when the result information obtained by executing the transaction task is inconsistent with the result information indicated in the proposal message, acquiring, from a snapshot of another node in the blockchain system, readset information corresponding to the block identifier in the proposal message, wherein the another node is a node in the blockchain system other than the first node (306); and restoring the state data on the basis of the readset information to obtain restored state data, wherein the restored state data is used for re-executing the transaction task to obtain an execution result (308).
