An ocean data resource sharing method based on a block chain

Abstract

The invention discloses an ocean data resource sharing method based on a block chain, comprising the following steps of enabling a data owner to broadcast the description information of the released ocean data to all nodes on the data storage chain; allocating all nodes in the chain with data storage rights according to filtering rules and competing to become data storage parties; publishing storage request information to a data owner according to the description information; after receiving the storage request information, using the data owner to send the encrypted ocean data to the data storage party with the set number of signature tokens as the storage cost; using the data storage side to extend the description information of the ocean data to its own address and publishes it to the data storage chain as the block data, which generates a new block link to the end of the block chain and timestamps it. Based on the block chain technology, the invention constructs a block chain for sharing marine data resources, realizes the free release, independent discovery and flexible delivery of marine data, and provides a solid guarantee for the safe sharing and transaction of marine big data.

Description

technical field [0001] The invention belongs to the technical field of marine data resource sharing, and in particular relates to a blockchain-based marine data resource sharing method. Background technique [0002] Since the founding of New China, my country has continued to carry out various marine surveys, observations and monitoring activities, as well as international cooperation and exchange of marine data, and has acquired and accumulated a certain amount of all-disciplinary marine data and related information, covering my country's coast, offshore and even the world. sea ​​area. [0003] Due to historical conditions and other reasons, my country's early ocean data were mostly stored in the form of paper, CD or tape, which severely limited data sharing services. Although some ocean-related departments and institutions in my country have established centralized sharing platforms as the main body, which have played a certain role in scientific and technological innovati...

Problems solved by technology

[0003] Due to historical conditions and other reasons, early marine data in my country were mostly stored in the form of paper, CD or tape, which severely limited data sharing services

Although some ocean-related departments and institutions in my country have established centralized sharing platforms as the main body, which have played a certain role in scientific and technological innovation and the development of the national ocean industry, the system performance of ocean data sharing services is still low. There is no interoperability between platforms, security and credibility cannot be guaranteed, and shared records cannot be traced back

[0004] The poor performance of the existing sharing platform has severely affected the enthusiasm of many ocean data holders to share data, and to a certain extent has restricted the rapid and sustainable development of my country's marine science and technology and marine economy, making domestic ocean data sharing services unable to compete with international counterparts. It is even more difficult to meet the current needs of the implementation of my country's "marine power" strategic goal
