Using Blockchain and Smart Contract for Traceability in Agricultural Products Supply Chain

The current supply chain of agricultural products is a complex ecosystem involving multiple stakeholders, which makes it difficult to verify several important characteristics, such as the origin of products, the growth stage and quality of crops. In this paper, we propose a method to efficiently execute agricultural products transaction by using consortium blockchain and smart contract, so as to track agricultural products in the whole supply chain. Our solution eliminates the need for trusted centralized authorities and agents, and provides trusted transaction records to improve the integrity, reliability and security of transactions. The proposed solution focuses on the use of smart contracts to manage and control all interactions and transactions between all participants in the supply chain. All transactions are recorded and stored in the immutable ledger of the blockchain, thus providing a high level of transparency and traceability to all supply chain ecosystems in a secure, credible, reliable and efficient manner.
