分析了中国“海洋数据孤岛”问题的本质原因，提出了一种基于区块链技术的海洋数据资源共享应用模式，改良了区块节点的共识机制和海洋数据在区块链上的存储方式，构建，海洋数据资源共享平台，以达到推动海洋数据的开放共享与增值流通的目的。
Marine data, as one of the important tools of ocean exploitation and utilization, scatter in various departments in our country, such as marine departments, scientific research institutions and other relevant enterprises. These data cannot be shared and value-added effectively, thus marine data islands are formed. This paper analyzes the fundamental reason for the marine data islands problem, then proposes a kind of marine data resource sharing application model based on block chain technology, in which the consensus mechanism of block nodes as well as the storage mode of marine data on the block chain are improved. Eventually, a marine data resource sharing platform is built to reach the goal of data sharing and value-added distribution.
