Problems solved by technology

The former data synchronization efficiency is low, the real-time performance is not strong, and additional redundant storage overhead is added, and the query from the off-chain database has been separated from the blockchain, and the data is not reliable
The latter structured the blockchain block data and transaction data and stored them in a relational database. For the existing Key-Value-based storage architecture, the transformation cost is high and the performance is not as good as NoSQL

Embodiment Construction

[0027] The purpose and effect of the present invention will become more obvious by describing the present invention in detail according to the accompanying drawings and specific embodiments.

[0028] A blockchain data indexing method, specifically as figure 1 shown, including the following steps:

[0029] S1, the blockchain client generates a blockchain transaction and sends it to the verification node;

[0030] The blockchain transaction includes transaction participants, transaction generation time, transaction note information and transaction note index information, and the transaction participants include a transaction sender and a transaction receiver. Wherein, the transaction note information field and the transaction note index information field are extensions of the present invention to the existing transaction data structure.

[0031] The transaction note information field is any business-related data customized by the client, such as certificate deposit hash, commo...

Abstract

The invention discloses a blockchain data indexing method. The method first persists the block to the block file, persists a layer of index data to the index database, and then obtains the matching transaction position according to the query condition, and finally obtains the transaction position from the block Files get fully traded. By expanding the processing process of blockchain data storage, the present invention stores blockchain index data in an independent index database and ensures the atomicity of multi-database transactions. Define the transaction note index field to correlate the connection between the transaction and the business information, and finally obtain the data index mechanism of the complete transaction based on the key information of the transaction; since it is not necessary to retraverse and parse the blocks on the blockchain, it can quickly index to the specific transaction , which greatly improves the efficiency of blockchain transaction backtracking, and at the same time ensures data reliability, laying the foundation for transaction data backtracking.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a method for indexing block chain data. Background technique [0002] With the rapid development and popularization of blockchain technology, the technical research of blockchain and its derivative applications have also shown explosive growth. The characteristics of blockchain data that cannot be tampered with, data can be verified, and data can be traced make it a core cutting-edge technology for realizing smart government affairs, smart medical care, charity tracking and traceability. Existing blockchain systems generally adopt a hybrid storage architecture of Key-Value database storage engine and file storage. Continuous data such as blocks and transactions are stored in files, and other data are stored in Key-Value NoSQL databases. Therefore, for data retrieval, only coarse-grained queries can be performed based on the Key value, and the structured data of ...
