Applied Research Of Intelligent Contract Based On Block Chain Technology In Northeast Grain Network

After 20 years of development,various e-commerce platforms are becoming more and more mature,and now they have entered a comprehensive and vertical development stage.In order to promote Liaoning's grain e-commerce trade and logistics services,Liaoning grain e-commerce trade and logistics services were studied in depth.Liaoning grain group and Shenyang Normal University jointly implemented the project of "Northeast spot grain e-commerce trade and logistics service platform".The contract signing part of the whole transaction process of Northeast Grain Spot E-commerce and Logistics Service Platform adopts the form of electronic contract of third party organization.Electronic contract can be signed on PC or mobile phone,which improves the efficiency of signing,and digital signature ensures the security of the contract.But at the same time,the electronic contract needs the third party platform to operate,which has the characteristics of centralization,and will bring certain risks to users;moreover,users need to pay a certain signing fee to sign an electronic contract platform.As a new concept,block chain has its unique attribute-decentralization.Block chain technology has the characteristics of de-centralization,timestamp data,convenient programming and security.It is especially suitable for building programmable virtual currency system,financial trading system and other social systems suitable for the application scenario.Block chains are "credit" machines.With secure hashing algorithm,reverse link data structure and consensus mechanism as the core technical elements,it can be widely used in the fields of protecting network data integrity,reliable network communication and traceability.Block chain advantage links each block containing data in chronological order to form a data link,and relies on cryptographic algorithms to ensure the untouchability,modification and unforgeability of distributed accounts,which mainly solves the trust of both sides of the transaction and the security of the transaction process.Decentralization is the natural attribute of block chain technology,avoiding the participation of third-party platforms and reducing risks.Using the advantages of block chain,such as openness,distribution,low cost,high security,traceability,intelligent contract and so on,we can solve many problems in transaction credit,data interchange,data storage and data security,explore and prospect its application in the field of network e-commerce,and provide some reference value for future related research.Block chain is an innovative application thatintegrates various underlying technologies as a technical solution that does not rely on third parties and stores network data,validates information and transfers it to other nodes through distributed nodes.Block chain not only has broad prospects for development,but also has huge market space,but also has a certain gap with the original idea.
