Design And Implementation Of Halal Food Tracking System Based On Blockchain Technology

Has long been cases of halal food are,the reason is that it can tamper with too much information,the use of information sent Keng Pian people achieve the purpose of profit,how to ensure that people's rights and interests,ensure that the existing information not been tampered with,how to create a platform for all the other people believe that is the bottleneck of blocking many areas development,until the invention of the block chain and development.To meet this requirement,a halal food traceability system based on security considerations of blockchain is designed.It adopts three-layer architecture design,namely,access layer,core layer and presentation layer,which respectively correspond to data input,use of blockchain and intelligent contract,and user interaction.The data input method is 4G+app;The core layer is the block chain network,which packages,consensuses and chains the information of the supply chain.The presentation layer USES the B/S architecture to build a web site to provide query interaction.Through this system,all the information in the supply chain is stored and can be guaranteed not to be tampered after being saved.When consumers want to fulfill the right to know about products,they only need to open the traceability webpage,type in the identification code or scan the QR code to obtain all the information of purchased products.
