Food Safety using Blockchain

Food safety management is an inevitable issue in the field of human health and social stability. It is expensive to monitor all entities that are involved in the food chain because it’s a large scale network. Traditional supply chain and management systems have various issues like data invisibility, tampering and sensitive information disclosure. The existing traceability systems adopt either centralized architecture or distributed architecture. Blockchain is a disruptive technology consisting of blocks where each block contains a hash of the previous block, thereby creating a chain of blocks. The concept behind blockchain is a mutual trust based on cryptographic techniques. A traceability system based on blockchain can help to increase the efficiency of managing the supply chain. Advantages of blockchain include better visibility of data. The cost of tampering with data is high hence it is reliable. Until now, many researchers came with their version of implementation of blockchain for this purpose but each one has some restrictions. The proposed method has better performance in various aspects like transparency, security, traceability and better management of sensitive data
