Design a Tracing System for a Seed Supply Chain Based on Blockchain

摘要

Blockchain technology performs a process of storing inside a record, and this ledger is raised on a large number of parties (computers, servers). Records are encrypted and cannot be tampered with, as happens in centralized systems. In order to solve the problem of manipulating or modifying information and knowledge of the origin of the product and increasing the consumer's transparency of the product coming from a series of the supply chain, this research suggests building a system to tracing the product. All product information is stored in serial blockchain through an algorithm that organizes the work of each part of the supply chain and the information it stores. Also, an algorithm to retrieve product information by searching for Blockchain. The results are expected to be important in terms of increased food security and increased competition between distributors. The entire purpose behind supply chain the management and coordination are to give customers the level and nature of administration that they require and to do as such at less expense to the complete supply chain. Traceability is a big necessity in supply chain ventures, particularly for the agri-food industry. Building a product tracking system in a supply chain to enable the consumer and government agencies to track and know the source and origin of the product in an easy, safe and reliable way from tampering and provide the fixed system the just manager can approve accepted users that be trusted people because will add data that all world will see it for that in the system, we build an algorithm to generate the activation key for adding a client.
