Problems solved by technology

However, in practical applications, different users may choose different blockchain systems for depositing certificates. For example, some data is stored in blockchain system A, while other data is stored in blockchain system B. Therefore, the During data verification, it is often necessary to query two blockchain systems in turn, which seriously reduces the verification efficiency

Abstract

The invention discloses an index database generation method, a data verification method and device and a platform. The platform comprises N blockchain systems, wherein N is larger than or equal to 1.The index database generation method comprises the steps that blockchain data of each blockchain system is obtained; index information of all storage data in all blocks of a local blockchain is extracted, wherein the index information comprises the block height of the block where the storage data is located, the position information of the storage data in the block and the identifier of the blockchain system, and the storage data is fingerprint information of the data stored and verified in the blocks; the index information is stored in an index database. Each piece of storage data in the blockchains can be precisely positioned through the block height, the position information and the identifier of the blockchain system in the index information so that quick verification in the multi-blockchain system can be achieved.

Description

technical field [0001] The invention relates to the technical field of data authentication, in particular to an index database generation method, a data verification method, a device and a platform. Background technique [0002] In modern life, it is often necessary to prove the existence of a certain data (thing), that is, the storage of data, such as written articles, historical operation instructions, signed contracts, etc. At this time, it needs to be certified by a third-party certification agency , this certification method has extremely high requirements on the credibility of the certification body, and the operation is cumbersome, the cost is high, and the timeliness is poor. [0003] In order to solve the above-mentioned various problems in data storage through third-party certification agencies, there have been many solutions for data storage through blockchain, which can be solved well by using the decentralized structure and immutable characteristics of blockchai...
