Abstract
A method of synchronizing blockchain state data, where account state data in the blockchain is organized into a Merkle state tree and stored in a database; the Merkle state tree includes a current Merkle state tree formed by a latest account state of each blockchain account; and a history Merkle state tree formed by a history account state of each blockchain account; and the method includes: receiving a data synchronization instruction for the Merkle state tree; in response to the data synchronization instruction, obtaining in real time the current Merkle state tree of the latest block stored in the database of other node device in the blockchain; and storing the obtained current Merkle state tree of the latest block to the local database to complete real-time data synchronization for the Merkle state tree.
