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.
