Research on Water Rights Trading System based on Blockchain Technology

For the large amount of data volume, fast update, high timeliness, cumbersome transaction processes, high data sharing requirements, high transaction costs, etc., decentralization, high security and reliability, scalability, high sharing, intelligentization, blockchain technology has a strong superiority in the construction of smart water affairs. According to the characteristics of water rights transactions, the Hyperledger Fabric of the Alliance Chain Project is selected as the underlying network system of the water rights trading system to build a water right trading prototype system. Layer architecture, build a three -channel bookkeeping method for designing the alliance chain multi -channel technology, designing confirmation, transactions, and registration, designing the chain code of water rights transaction, and achieving multi -chain operations through chain code calls, which can not only meet different data between institutions, Sharing demand can also increase the throughput of the entire Fabric network. The water right trading system based on the blockchain can simplify the water rights transaction process and reduce the cost of water rights transaction. The system has the characteristics of high scalability, efficient and controllable dynamic management, safe and reliable, low cost, and convenient management operation and maintenance. Transactions provide new ideas more efficiently and safely.
