Abstract

The invention discloses a data storage method and device based on a block chain and a medium, and the method comprises the steps: obtaining a core block chain, wherein the core block chain stores partor all of write chain information; determining a first block chain located in front of a first block through the first block in the block chain; and judging whether the core block chain contains thefirst block chain or not, if so, deleting the first block chain, and taking the first block as a new creation block. By defining the core block chain, improvement is carried out on the basis of not violating the basic concept of the block chain, each node has the selection right for data in the block chain and the selection right for the core block chain while enjoying the supervision right and the voting right, the storage cost of the nodes is greatly reduced, and the authenticity and reliability of the data are guaranteed.

Description

technical field [0001] The present application relates to the technical field of blockchain, in particular to a data storage method, device and medium based on blockchain. Background technique [0002] With the popularization of blockchain technology, the block data generated every moment will reach a very high level. This has caused the problem of data storage, which is very unfriendly to hard disk storage, and even less friendly to newly added nodes. Contents of the invention [0003] The embodiment of this specification provides a data storage method, device and medium based on blockchain, which are used to solve the following technical problems in the prior art: [0004] The massive amount of data in the blockchain puts a lot of pressure on the newly added nodes and the storage devices of the original nodes, and the cost is high. [0005] The embodiment of this description adopts the following technical solutions: [0006] The first aspect of the embodiments of the ...
