Example Embodiment
[0041] In this embodiment, although several time effective digits are sacrificed, the hash value of the data record can be directly read, and the block height of the data block can be identified by a designated serial number (ie, 000 in Table 2).
[0042] The above index can be created immediately when the block is created, or it can be created asynchronously. The index itself can be used for some search or statistical operations, for example, to count the number of data records in a certain period of time, to avoid traversal counting from within the data block, which is more convenient.
[0043] By traversing all data blocks and writing the corresponding data records in all data blocks into the index table, the completed index table corresponding to all user data can be obtained. In the above index table, each data record has the block time of being written into the block (the block time of each data record in the same block is the same), and the order in which it is accepted by t...
