Abstract
Traditional application uses centralized database and the data is managed and maintained by a single institution. Blockchain is a decentralized, non-tamperable, traceable, multi-party distributed database, which can greatly improve the security of data. It is crucial to transfer traditional application to blockchain-based application for many application scenarios. However, as a new field, most developers are not familiar with blockchain technology. Therefore we propose a method to transfer the traditional application to application based on Hyperledger Fabric. First, we finish the secondary development of Fabric-sdk-java and define a set of API mapping rules. Secondly, we compare the storage model between Mysql and CouchDB, and implement a SQL-Fabric transformation engine through the smart contract, which can parse SQL and automatically transform into read and write operations on the distributed ledger.
