Embodiment Construction

[0116] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0117] An embodiment of the present invention provides a blockchain system, including M nodes, where M is greater than or equal to three. Among them, M nodes form a "decentralized" system through dynamic networking through a peer-to-peer network (Peer to Peer, P2P). figure 1 A schematic diagram of a feasible block chain system architecture provided for the embodiment of the present invention, such as figure 1 As shown, the blockchain syst...

Abstract

The invention discloses a block chain generation method, a data verification method, nodes and a system. The block chain generation method is used for increasing the utilization rate of a storage space and is applied to a block chain system containing M nodes. According to each of the M nodes, the block chain generation method comprises the steps that N pieces of fingerprint information corresponding to N pieces of to-be-written data are acquired, wherein N is greater than or equal to 1; a new block is constructed, wherein the new block comprises a data set and a block head; the data set comprises N pieces of fingerprint information; the block head comprises a Hash value of a block head of a previous block in a local block chain of the node, wherein the previous block is a newly added block in a longest chain of the local block chain; and through a consensus algorithm, a consensus block is determined from new blocks generated by M nodes and is added into the local block chain. In thisway, the storage space occupied by other information of non-to-be-written data in transaction information is saved, and therefore the utilization rate of the storage space and is increased.

Description

technical field [0001] The invention relates to the technical field of data authentication, in particular to a block chain generation method, a data verification method, a node and a system. Background technique [0002] In modern life, it is often necessary to prove the existence of a certain data (thing), that is, the storage of data, such as written articles, historical operation instructions, signed contracts, etc. At this time, it needs to be certified by a third-party certification agency , this certification method has extremely high requirements on the credibility of the certification body, and the operation is cumbersome, the cost is high, and the timeliness is poor. [0003] In order to solve the above-mentioned various problems in data storage through third-party certification agencies, there have been many solutions for data storage through blockchain, which can be solved well by using the decentralized structure and immutable characteristics of blockchain. the ...
