Blockchain query method based on distributed search engine, and storage medium

Abstract

The invention provides a blockchain query method based on a distributed search engine, and a storage medium. According to the method, after the file is written into the block chain, the search engine is introduced to perform word segmentation on the file, then the reverse index is established based on the file word segmentation result, the reverse index is subjected to fragmentation processing, and then the file ID meeting the condition can be obtained through the search engine according to the input condition; and the matched file content is quickly searched on the storage node through the file ID. According to the method, the distributed search engine is introduced to replace a relational database, the problems of block chain query function and efficiency are thoroughly solved, and meanwhile, the additional storage burden is relieved.

Description

technical field [0001] The invention relates to the field of block chains, in particular to a block chain query method and storage medium based on a distributed search engine. Background technique [0002] In recent years, blockchain technology has become well known with the popularity of Bitcoin in the investment market. Technically speaking, the blockchain is essentially a way of storing data records - chain storage. In terms of application, the blockchain forms a distributed ledger maintained by the collective through cryptography. Therefore, the blockchain has the characteristics of non-tampering, decentralization, traceability throughout the process, traceability, and openness and transparency. Based on these characteristics, blockchain technology is more and more widely used, and query browsing, as the most basic operation of each application, also puts forward high requirements on the response speed of the system. The implementation logic of the native blockchain q...

Problems solved by technology

However, the use of relational databases to solve the problem of insufficient query functions and performance of native blockchains has the following disadvantages: relational databases are usually centralized, which runs counter to the original intention of blockchain decentralization, and is easy to use in A single point of failure is caused in the application. After the relational database reaches 100 million-level data, the query efficiency is also low. By downlinking all the blockchain data to the relational database, the additional storage burden is heavy
