Block chain-based relational database synchronization method and synchronization system

The invention relates to a blockchain-based relational database synchronization method, which comprises the following steps of: dispersing different operations for a database by setting blockchain accounting nodes in one-to-one correspondence with a master database and slave databases, and analyzing different types of requests through database middleware; the data transmission communication pressure between the master database and the slave database can be reasonably distributed, the performance of a single database is prevented from being influenced by overlarge page view, and the fault-tolerant capability of the database is improved. 本发明涉及一种基于区块链的关系型数据库同步方法，通过设置与主数据库、从数据库一一对应的区块链记账节点将针对数据库的不同操作分散，通过数据库中间件解析不同类型的请求，能够合理的分配主数据库与从数据库之间的数据传输通信压力，避免单一数据库因访问量过大影响性能，并提高了数据库的容错能力。
