Abstract: Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage devices, for data processing. One of the methods includes determining, by a storage system from an index log file, information of a data log file stored in a storage device. The data log file includes one or more of block data, transaction data, or state data generated by a blockchain network.
