Distributed chain data resource directory and index management method

Abstract

The invention relates to a distributed chain data resource catalog and index management method, the method comprising the following steps: 1) catalog publication; 2) index online; 3) resource positioning; 4) index offline; 5) catalog withdrawal. This solution has high reliability, adopts a decentralized mechanism, and all nodes jointly maintain the entire system and data, which has strong fault tolerance and high reliability; high reliability, blockchain multi-center mechanism, cryptography principles and data The fully distributed storage ensures that the data on the chain cannot be tampered with.

Description

technical field

[0001] The invention relates to a management method, in particular to a distributed chain data resource directory and index management method, and belongs to the technical field of data resource management. Background technique

[0002] With the vigorous development of big data, cloud computing, and the Internet of Things, data is a strategic asset for the government and society. Data resources usually have the characteristics of large quantity, wide categories, and scattered distribution. In order to give full play to the value of data, it is first necessary to build a data resource directory system and provide a complete and reliable "information resource map" so that data consumers can quickly and Accurately and comprehensively understand and master the basic situation of information resources, discover and locate the required information resources. Therefore, how to manage data resources on the premise of ensuring information security has become an urgen...
