Blockchain technology can be utilized to trace seafood products by creating a decentralized and tamper-proof record-keeping system that tracks every step of the seafood's journey from catch to consumer. When a fish is caught, the details such as the species, location, and time of catch can be recorded on the blockchain. This information can then be updated at each stage of the supply chain, including when the fish is landed, processed, transported, and finally sold to the consumer. Each transaction along the way is recorded as a new block of data and linked to the previous one, forming a chain that provides a complete history of the product. This process is secured by cryptographic algorithms, which ensure that once a block is added to the chain, it cannot be altered retroactively. This immutability is crucial for preventing fraud and ensuring the integrity of the data. Smart contracts, which are self-executing contracts with the terms of the agreement directly written into code, c
