Abstract
This disclosure relates to blockchain-type data storage. In one aspect, a method includes receiving, by a database server, multiple second data records. Each second data record includes a first data record having a user identifier and a digital signature of the first data record. Hash values of the second data records are determined. In response to a blockchain-type block generation condition being satisfied, the database server determines two or more second data records to be written in a data block. An Nth data block that includes a hash value and a block height is generated. N is a sequence number of the Nth data block in a sequence of data blocks. When N>1, generating the Nth data block includes determining the hash value for the Nth data block based on the hash values of the two or more second data records and a hash value of a (N−1)th data block.
