OCEAN OBSERVATION DATA TRANSMISSION AND SHARING SCHEME BASED ON BLOCKCHAIN
With the rapid growth of various ocean observation data,the problems of data inconsistency and non-traceability in data transmission,as well as security and trust issues in data sharing have become increasingly prominent.In response to the above problems,a blockchain-based ocean observation data transmission and sharing scheme is proposed.The scheme utilized the autonomy and non-tampering characteristics of blockchain,as well as technologies such as smart contract,digital signature and digital envelope to build an ocean observation data transmission consortium chain and a shared consortium chain based on cloud storage and blockchain network.The design of the new data transmission scheme,secure data sharing access mechanism and incentive mechanism provides a solution to promote the efficient and high-quality transmission and the safe and honest sharing of national ocean observation data.
