Development Of Agricultural Order Platform Based On Blockchain

In recent years,with the development of breeding industry and Internet technology,order farming based on online trading platform has become a new mode of agricultural production cooperation between supply and marketing.It not noly solves the problem of imbalance between supply and demand of farmers and the market,but also effectively reduces the blind input.However,there is a problem of transaction mutual trust and opaque business chain in order farming,which is prone to shortage of funds,unilateral default and product quality.At present,most of the ways to solve such problems are human judgment and legal supervision.However,the traditional"guarantee" model cannot solve the supply quality problem from the root cause,and legal decision can not be implemented effectively.With the development of the Internet of Things and the arrival of the era of big data,the blockchain technology based on smart contract provides a new solution to solve the problem of order agriculture.This paper studies the agricultural order technology based on blockchain by using the advantages of blockchain technology,such as tamper resistance and traceability,and carried out the following work:(1)An agricultural order platform based on blockchain was developed to combine blockchain technology with agricultural farming operations.Using the chain code and consensus mechanism in the Hyperledger Fabric model to achieve contract chaining and information query in the transaction process,not only can prevent the contract information from being rewritten unilaterally during information storage,but also transparently transact the transaction information,thus avoiding problems such as mutual trust and tampering in transactions.(2)Comprehensive analysis and implementation of the management modules and order transactions involved in the order farming,and the related business of investors is introduced into the platform,and realized the intelligent management of suppliers,markets and participants.(3)Aiming at the problem of slow information acquisition and slow query in blockchain technology,the order platform is improved by using Internet of Things technology and database technology,The collection equipment,transmission system and agricultural order platform are connected,realizing real-time uploading of the animal husbandry environment information,the data timing update and the timely sharing of information.The test shows that the platform can quickly link and store the agricultural order information,and ensure the stability of the system and the soundness of the data in case of partial node failure.
