Blockchain has attracted more and more attention in recent years because it can provide tamper-proof, transparent, safe and efficient data storage functions. As its functions continue to improve, more and more startups are beginning to use blockchain technology for data storage and management. However, unlike database systems in traditional Internet applications, the data asset storage method of the blockchain platform is not written directly into the database, but by recording all data on the blockchain for storage and management. Therefore, this article will elaborate on the combination of Open Data Platform and blockchain, and explore how blockchain can help realize the management of "open data assets". First, what is an “open data asset”? This is a relatively vague term, and different people may understand it differently. For example, one statement means that in addition to the confidential information you own, you can also obtain data resources published or shared by other third parties. Another term refers to data that can be obtained, downloaded and used by any individual or organization, including public services provided by different institutions such as government, media, banks, telecom operators, etc.
Based on the above definition, "open data assets" refer to data that can be obtained, used or shared by people at will, which in the real world may be policy data, economic data, medical data, health data, etc. At present, "open data assets" have become one of the important ways for various government departments, enterprises, organizations, media groups and other organizations in many countries to share and transmit information.
So, how does blockchain technology help realize the management of “open data assets”? Open Data Platform is an open data sharing platform based on blockchain technology. It is mainly divided into four modules: information collection, information storage, information indexing, and information flow. Among them, the information collection module is responsible for collecting and recording all information that needs to be protected. The information storage module records these data on the blockchain to ensure that the information cannot be tampered with and is traceable. The information index module can index the data submitted by users according to keywords and store the index results on the blockchain. Finally, the information flow module uses the data sharing function on the blockchain to allow users to freely exchange and circulate this data. In addition, Open Data Platform can also provide
