Embodiment Construction

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is only some embodiments of the present invention, but not 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.

[0044] The non-negotiation consensus mechanism adopted by the present invention adopts a rule agreed in advance and a built-in rule between nodes, and introduces unpredictable random factors on top of the rule, so as to achieve the effect that the consensus result cannot be predicted in advance. The present invention uses a consultation-free ...

Abstract

The present invention provides a consensus method and device for a block chain system based on non-negotiation random lottery. The method includes: after receiving a legal block, determining the currently qualified nodes according to the trust certificate list of the whole network; performing non-negotiation random draw on the currently qualified nodes to obtain a sequence of nodes arranged in order, the The sequence determines the only block-producing node that is eligible to produce a block at each specific period of time that follows. In each subsequent specific period of time, the block-producing node sends the pre-produced block and collects the endorsement; after the endorsement node receives the endorsement request, it checks the legitimacy of the pre-produced block and signs the legal pre-produced block; After more than 50% of the endorsement signatures, the endorsement signatures are added to the pre-produced block to form a formal block and broadcast to the entire network. The present invention can prevent malicious nodes from manipulating lottery results and ensure the security of blockchain operation; Real-time transaction of the system.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a consensus method and device for block chain systems based on non-negotiation random lottery. Background technique [0002] Each node of the blockchain locally maintains a ledger composed of links between previous and subsequent blocks. Each block records the changes experienced by the ledger from the previous state to the next state, which is embodied in the block as a collection of transactions. and its sequence. The so-called input consensus means that on each node of the blockchain network, the blocks of the same height contain the same set of transactions and their order is consistent. The input consensus is the guarantee for the blockchain system to achieve the consistency of the ledger - if each node is consistent in the initial state, and the changes experienced by migrating from the previous state to the next state are also consistent, then their latter st...
