Block chain token-based rice supply chain digital transaction method

Abstract

The invention provides a block chain token-based rice supply chain digital transaction method, and relates to the fields of block chains, Internet of Things and the like. The method comprises the following steps: firstly, designing a digital transaction platform based on an intelligent contract and a block chain technology, forming participants by all enterprises, consumers and supervision departments, and distributing digital identity representative pass certificates and digital wallets to the participants after identity authentication; then, the passing of the rice assets is realized through the exchange; and the participants match the respective rice token with the identity representative token to form a unique token. The buyer and the seller realize layered transaction of funds and rice through respective unique token; according to the invention, interconnection and intercommunication between the sub-chain and the main chain are realized by adopting an asymmetric encryption mode, the designed token ensures complete credibility of a rice digital transaction environment, rice traceability and supervision services are provided at the same time, and a perfect reference and research thought is provided for realizing digital transaction of grain and oil crops.

Description

technical field [0001] The present invention relates to the fields of next-generation information technologies such as blockchain and the Internet of Things, financial digitization, and food safety management, and specifically relates to a digital transaction method for rice supply chains based on blockchain tokens. Background technique [0002] With the continuous development of agriculture, in 2020, the national rice output will be 423.7 billion catties, an increase of 4.5 billion catties or 1.1% over the previous year. And the area per unit area in my country is increasing year by year. In 2018, China's rice yield per unit area was 7.027 tons / ha, a year-on-year increase of 1.59%; in 2019, China's rice yield per unit area was 7.059 tons / ha, a year-on-year increase of 0.46%. my country's rice consumption in 2019 / 2020 is 145 million tons, and it is expected that China's rice consumption will reach 147 million tons in 2020 / 2021. Under the huge rice base, the traditional rice...
