A blockchain-enabled system for decentralized autonomous maritime navigation safety (DAMNS) is proposed. Shipping companies, maritime authorities, and navigational service providers can collaborate through DAOs to enhance maritime navigation safety. The system uses blockchain to record real-time information about weather conditions, sea routes, and vessel movements, providing sailors with accurate and up-to-date navigation data. Smart contracts can also be used to enforce safety regulations and manage insurance claims in case of accidents. #DAMNS #MaritimeSafety #BlockchainShipping
