Communication processing method for seafood information monitoring based on Internet of Things and block chain

The invention discloses a communication processing method for seafood information monitoring based on the Internet of Things and a block chain. According to a communication process of seafood information, components and block chain nodes of seafood information monitoring are determined; the system comprises a seafood supply system, a logistics vehicle, processing equipment, a vending machine, a user terminal and an auditing control system, wherein each component establishes a block chain node, a seafood information alliance block chain is constructed according to the block chain nodes, and generated/processed food information is published to the block chain through the block chain nodes; based on the food information in the block chain and a preset intelligent contract, communication processing is performed on the seafood information, thereby realizing monitoring of the seafood information. Effective processing of the whole life cycle of seafood is realized, information counterfeitingis prevented, and seafood
