A method for capturing and analyzing block chain ledger data

Abstract

The invention discloses a method for capturing and analyzing block chain ledger data, including steps: S1, designate a block chain node that needs to be captured and analyzed, establish a connection with the block chain node, and obtain all channels in the node; Each channel starts the capture data thread, registers the event listener, listens to the block event of the channel, and captures the ledger data; S2, after capturing the ledger data, parses it, and parses out the block and transaction data; S3, the The parsed data is stored in sub-databases and tables according to channels, block hashes, and transaction hashes; S4, expands the database; S5, migrates data, etc.; the present invention provides blocks and transaction data for the blockchain system Analysis, storage, and query services, data are partitioned and stored according to different blockchain channels, and the storage can be dynamically expanded and migrated, and at the same time, the pressure of data access can be evenly shared, and the read and write performance can be improved.

Description

technical field [0001] The present invention relates to the technical field of blockchain, and more specifically, to a method for capturing and analyzing blockchain account book data. Background technique [0002] The core concept of the blockchain is a distributed ledger. The same full amount of transaction ledger data is stored in any node. The ledger is a time-series linked list composed of multiple blocks, and each block contains multiple transactions. The linked list formed. The blockchain system provides a query service for ledger data, but there is no convenient analysis and query service for the query presentation of blocks and transaction data and related statistical information. At the same time, the blockchain itself is also a growing data. The accumulative system, especially in the application scenario with a large amount of transaction data, the rapid growth of data, the scalability of data storage and the performance of data query services are difficult to mee...

The blockchain system provides a query service for ledger data, but there is no convenient analysis and query service for the query presentation of blocks and transaction data and related statistical information. At the same time, the blockchain itself is also a growing data. Continuously accumulating systems, especially in application scenarios with a large amount of transaction data, the rapid growth of data, the scalability of data storage and the performance of data query services are difficult to meet

[0003] The current blockchain data query account book information is not convenient enough, and it cannot provide block and hash query services for blockchain data well, and the account book data continues to accumulate over time, and the subsequent data is getting larger and larger. Both capacity expansion and read / write performance will encounter bottlenecks
