Design of Hazard Management Method Based on Blockchain

This paper proposes a blockchain-based hazard management method. Firstly, the data structure and operation types of hazards in civil aviation risk management are analyzed in detail. Secondly, a blockchain is designed to maintain all the data items of hazards, including but not limited to state data and operation data. In addition, the latest state of hazards is stored in a global hash list for quick query. Finally, a hazard management method based on the above blockchain is proposed.
