Abstract

Embodiments of the present application provide a data processing method and device. The method includes: distributing, to servers in a server cluster, data of leaf nodes prestored in a blockchain node, for the servers in the server cluster to compute checksums of the data of the distributed leaf nodes, respectively; and obtaining, according to the checksums of the data of the leaf nodes computed by the servers in the server cluster, a root checksum of data in the blockchain node. The embodiments of the present application may be used to reduce the time taken by a data checksum computation process, improve the computation efficiency, and ensure normal generation of blocks and normal operations of a blockchain.
