SYSTEM AND METHOD FOR AUGMENTING DATABASE APPLICATIONS WITH BLOCKCHAIN TECHNOLOGY

摘要

A method for augmenting a database application with blockchain technology is disclosed. The method involves recording data modifications made by a database application into a corresponding database as well as on a blockchain for global consensus confirmation. This is done without changing the existing application architecture and with minimal code changes to the existing application. Records in the database requiring synchronization with the blockchain are subjected to consensuses voting, and unauthorized database changes are rolled back, thereby granting immutability and non-repudiation characteristics to a traditional database application. Records in databases are thus made globally consistent. An existing database application can be deployed on a blockchain without significantly modifying the code. Multiple applications can synchronize data through a common blockchain, which greatly simplifies building blockchain applications.
