Water right transaction method and system

Abstract

The invention discloses a water right transaction method and system based on a block chain. The method comprises the steps that a water right distribution node creates at least one intelligent contract in a water right transaction period and writes each intelligent contract into at least one block, and nodes corresponding to a block chain where the block corresponding to the intelligent contract is located comprise a water right distribution node, a plurality of water right transfer party nodes, a plurality of water right transferee nodes and a plurality of accounting nodes; the water right transfer party node generates transaction order data according to the water right account address of the transfer party node, the water right account address of the water right transfer party node and the current water resource transaction amount; the water right transfer party node signs the transaction order data according to the private key of the water right transfer party node and packages and broadcasts the signed transaction order data; and the signed transaction order data is verified by a plurality of accounting nodes in the block chain, and the transaction order data is recorded on the block chain after the verification is passed. The technical scheme provided by the invention can ensure that the water right transaction is effectively carried out.

Description

technical field [0001] This application relates to the technical field of data processing, and in particular to a blockchain-based water rights trading method and system. Background technique [0002] Since the water rights owned by individuals are limited, and farmland irrigation often requires a large amount of water resources, it is difficult for individuals to be the subject of water rights transactions to meet the demand for agricultural water. Therefore, water rights transactions usually take "water rights groups" as the main body. Water rights groups can be water user associations, water districts, water companies, local self-government groups, etc. All water rights groups are eligible to buy and sell water rights. [0003] At present, the common way of water rights transaction is direct transaction between the transferor and the transferee, or through a transaction platform with relevant qualifications. [0004] However, the transferee cannot directly judge whether...

Problems solved by technology

[0004] However, the transferee cannot directly judge whether the water rights transaction data provided by the transferor is valid, so the transferee may question whether the transferor can complete the water rights transaction process, but cannot obtain definite evidence, which will hinder the water rights transaction carry out effectively
