Abstract
This application relates to a shared data recovery method performed at a first node of a data sharing system. The first node obtains a first eigenvalue of a first node after receiving a recovery request carrying a first block height; broadcasts the first eigenvalue to at least one second node and recovery indication information to the at least one second node. After determining, based on the first eigenvalue and a plurality of second eigenvalues, that data in shared data stored by all nodes of the data sharing system is consistent, the first node recovers data within a range of the first block height in the shared data after receiving a preset quantity of a plurality of pieces of recovery indication information, thereby ensuring consistency and security of data included in a block, and reducing pressure on a node of the data sharing system to store the shared data.
