Abstract

The invention relates to a block data marking method and device based on a block chain. The method comprises the following steps: firstly, adding a intelligent contract of block chain marking information in a related code of the block chain; dividing the data written into the block chain into three types: non-change information, changed information and cross-chain information; different marking modes are adopted for different types of information; when a user has a request in a certain aspect, the block chain locks marked information according to different requests, and feeds back the requests to the user according to different marking modes; according to the method, on the aspect of the block chain technology, a block information marking mode and an information classification mode are provided, so that the information stored in the block chain becomes flexible and diversified.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a method and device for marking block data based on block chains. [0002] technical background [0003] Blockchain technology is a distributed data storage technology; blockchain includes blocks and hash chains, in which various data are stored in blocks, and hash chains are used to establish connections between adjacent blocks and blocks A chain structure; wherein, the block is composed of Merkle tree structure, parent hash value, timestamp and block header; the hash chain has the function of consensus and information transfer of the block, in which the The hash value of the block is passed to the adjacent next block, which is a form of hash chain passing information. [0004] Due to the unique functions and functions of blockchain blocks and hash chains, the constituted blockchain system has the functions of decentralization and non-tampering. [0005] The decent...
