Abstract

The invention relates to a block chain data processing method supporting relational retrieval. The method comprises the steps of obtaining transaction data and block head data in block chain data; storing the transaction data into a preset transaction table of a first preset database, the first preset database being a block chain underlying database, and the preset transaction table being providedwith a block number field; storing the block header data in a preset block table of the first preset database, wherein the preset block table is provided with a block number field; and establishing amapping relationship between the transaction data and the block header data based on the block number field. By implementing the method and the device, the block chain data can support fine-grained content-based retrieval of a transaction level, and meanwhile, the block chain data can support SQL (Structured Query Language), and complicated query operation can be carried out.

Description

technical field [0001] The invention relates to block chain data management, in particular to a block chain data processing method, device and equipment supporting relational retrieval. Background technique [0002] Blockchain is the core cutting-edge technology for realizing smart cities, smart medical care, e-government, etc. It has the characteristics of traceability and verifiability. However, its only append-type characteristics lead to its data expansion, and it is urgent to propose an efficient data organization and management mechanism. . The existing blockchain technology adopts a simple key-value model, the data is unstructured, and the type of retrieval supported is single, making it difficult to organize and utilize blockchain data. Therefore, it is necessary to use a relational database to manage the underlying data of the blockchain, so that it can support SQL queries, thereby enabling efficient retrieval, and supporting complex queries, which enriches the ret...
