Problems solved by technology

[0005] The main purpose of the present invention is to provide a consensus establishment method based on the lottery mechanism, which aims to solve the problem that the proof-of-stake consensus mechanism tends to occupy nodes with large rights and interests in the system, which is easy to cause corruption and is not conducive to attracting more groups to use the blockchain. technical problem

Embodiment Construction

[0042] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] In the following description, use of suffixes such as 'module', 'part' or 'unit' for denoting elements is only for facilitating description of the present invention and has no specific meaning by itself. Therefore, 'module', 'part' or 'unit' may be used in combination.

[0044] Such as figure 1 as shown, figure 1 It is a schematic diagram of the block chain system of the embodiment of the present invention.

[0045] The blockchain system includes a plurality of nodes. When creating a new block, one or some nodes execute a specific program or specific function, which is recorded as an accounting node in the embodiment of the present invention. Other nodes in the blockchain system For ordinary nodes, each created block has its own definite bookkeeping node. Bookkeeping nodes and ordinary nodes are not fixed a...

Abstract

The invention discloses a consensus building method based on a lottery mechanism, a block chain system and a storage medium. The method comprises the steps that an accounting node of a last block in ablock chain is determined, and a data packet is acquired on the basis of the accounting node of the last block, wherein the data packet at least comprises transaction data of a to-be-connected blockpreparing to be connected with the last block; Hash operation is conducted on the basis of the acquired data packet and node data saved in the node to obtain a first candidate Hash value; a second candidate Hash value broadcast by other nodes is acquired, and a target Hash value is selected from the first candidate Hash value and the second candidate Hash value according to a first preset rule, wherein the node of the target Hash value is the accounting node of the to-be-connected block. According to the consensus building method, it can be guaranteed that all nodes in the block chain competefor the accounting permission in complete equality, more people can be encouraged to participate in the block chain, and therefore the method is beneficial for application and popularization of the block chain.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a consensus establishment method based on a lottery mechanism, a block chain system and a storage medium. Background technique [0002] The blockchain is a distributed database system in which nodes participate. It can also be understood as an account book system, which is completed independently by all nodes in the blockchain network. The consensus mechanism is the core of the blockchain technology, which makes a decentralized ledger system such as the blockchain possible. The two core factors of the consensus mechanism and decentralization are the key to the expansion of the endogenous capabilities of the blockchain. [0003] In a centralized structural system, the consensus of the system is determined by the center, and all participants only need to obey this center, so the establishment of consensus is extremely efficient. In a decentralized structural system, due to the...
