Tracing Food Products in Supply Chain Using DLT Enabled Blockchain Technology

Abstract

The most emerging new technology of trust is the concept of blockchain technology, which is a combined ecosystem of entwined dependencies of agricultural supply chain and agricultural produce. A sufficiently high transparency is the most essential requirement where agricultural produce and supply chain are to be implemented in a combined manner. Thus, blockchain is emerging as the most reliable and secure way to ensure consumer benefits. The ledger of records, usually maintained in the form of blocks, are encapsulated and maintained in a network. The newer records are stored in the next block and each of the existing block is connected to the newer block so that the sequence of blocks in maintained. Each block leads to the next block in the chain and the distributed nature of the network ensures transparency and integrity of each block. Any alteration in any block by any agent can be easily detected and the integrity can be maintained. Cryptography is another major concept that plays a pivot role in ensuring security and integrity of the blocks formed. Various types of online transactions, documentations, or records can be managed using blockchain technology. In particular, agriculture is a sector which fulfils the demand supply chain of food and the demand for better quality food is having the highest demand.
