A data block storage method, reading method, device and block chain

Abstract

The present invention discloses a data block storage method and reading method, apparatuses thereof, and a block chain. The storage method comprises: before writing a new data block in the block chain, converting transaction record data in each row in a transaction record structure of the new data block to the processing of storing the data in a column structure; creating column structure storageidentification information in the new data block stored in a column structure; and storing the new data block with the column structure storage identification information into the block chain. Since the transaction data in each row is stored in a column structure, and the column structure storage identification information is created, when querying the transaction record data, instead of queryingthe entire transaction record data, only the transaction record data of the corresponding column needs to be queried according to the identification information; a large number of system IO operationsare reduced, large-capacity and high-concurrent query requirements can be supported, and efficient data processing can be facilitated; and in addition, by extending the columnar storage structure, changes in the future transaction record details can be handled.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method for storing data blocks, a reading method, a device thereof, and a block chain. Background technique [0002] Blockchain is a distributed ledger, a technical solution for collectively maintaining a reliable database through decentralization and trustlessness. To put it simply, a blockchain is a data structure that combines blocks in a chain. It is suitable for storing simple, sequential, and verifiable data in the system. Cryptography is used to ensure the integrity of data. Unalterable and unforgeable. It enables participants to establish a consensus on the sequence of events and current state of transaction records across the network. [0003] In the blockchain technology solution, data is permanently stored in the form of electronic records, and the files storing these electronic records are called "blocks". Blocks are generated one by one in chrono...

AI Technical Summary

Problems solved by technology

[0016] In view of this, the embodiment of the present invention provides a method for storing data blocks, a method for reading them, a device thereof, and a block chain, to solve the problem that the system in the prior art has a large amount of IO operations and cannot satisfy high concurrent queries. Demand, does not support efficient processing of data, and does not support the problem of transaction record structure that may change in the future
