Abstract
A computer-implemented index creation method includes obtaining, by a server storing data in a blockchain ledger, an identifier, in which the identifier identifies an attribute value of a data record; determining location information of the data record in the blockchain ledger, in which the location information includes a block height of a data block in which the data record is located and an offset of the data record in the data block; and writing the location information into an index, in which the index stores a correspondence between the location information and the attribute value, the attribute value being used as a primary key in the index.
