Abstract
A method of constructing a high-performance anti-tampering database based on blockchain includes: acquiring change increment information corresponding to data to-be-stored through at least one of database nodes and storing the change increment information as bottom-layer data of all the database nodes based on a blockchain data structure; determining resultant data information based on the change increment information, indexing and then storing the resultant data information as top-layer data of all the database nodes; performing mutual-checks on stored top-layer data as per a predetermined mutual-checking period and performing self-checks on stored bottom-layer data as per a predetermined self-checking period, by the database nodes; and restoring the bottom-layer and/or top-layer data of the database nodes according to results of mutual-checks and self-checks, to realize database construction. Based on the two-layered database architecture, high reliability and high availability of data can be ensured, and anti-tampering performance can be improved.
