Abstract

The invention relates to the field of block chains, and discloses a data storage method and device, computer equipment and a storage medium.The method comprises the steps of newly establishing a transaction, wherein the transaction comprises a plurality of adding instructions; before the transaction is finished, adding a newly-added temporary node according to the adding instruction; after the transaction is finished, splitting the newly added temporary node into a plurality of split nodes, and calculating hash values of the split nodes; updating the key value pair list of the target father node, and judging whether the length of the key value pair list of the target father node exceeds a second preset threshold value or not; and if yes, continuing to split the target father node until thekey value pair list lengths of all nodes do not exceed respective corresponding preset thresholds. Through asynchronous processing of transaction processing and node splitting and coupling of node splitting and hash calculation, the transaction processing efficiency can be improved, the IO frequency of paths and index values of a transaction type Merkel B + tree is reduced, and the disk read-write time is shortened.

Description

technical field [0001] The present invention relates to the field of block chains, in particular to a data storage method, device, computer equipment and storage medium. Background technique [0002] In the prior art, MPT (Merkle Patricia Tree, Merkle Patricia Tree) is a common algorithm for storing blockchain data. MPT uses the leveldb database (a database developed by Google) to store data, which has the problem of read and write amplification. In addition, MPT is indexed by prefix, and the reading path is long, resulting in a large number of hash calculations and affecting access performance. Moreover, during the data storage process, frequent encoding and decoding consumes a large amount of computing resources, resulting in poor storage efficiency. Contents of the invention [0003] Based on this, it is necessary to address the above technical problems and provide a data storage method, device, computer equipment and storage medium to solve the problem of low efficie...
