Quick consensus bookkeeping method and system based on blockchain alliance chain

Abstract

The invention aims to provide a quick consensus bookkeeping method and system based on a blockchain alliance chain. The method comprises the following steps that: when a system is initialized, the system generates a sovereignty key used for generating a new block; a node collects trade information and waits for a new block broadcast; after the node receives the new block broadcast, the new block is added into a local block; the node which receives the sovereignty key generates the new block, and a new sovereignty key is created; the new block is broadcast to all nodes of the system; and the new sovereignty key is transferred. By use of the method, through a method that the certain node of the system is randomly selected to transfer the sovereignty key, only a certain node which can not be determined in the system has power and permission for generating the new block at any time, bookkeeping rights are randomly distributed among all honest nodes so as to guarantee that the system can quickly reach consensus while the trade information can not be tampered, and trade confirmation speed is shortened into a second level from an original minute level.

Description

technical field [0001] The invention relates to a fast consensus bookkeeping method and system based on a block chain alliance chain. Background technique [0002] With the development and maturity of blockchain technology, the number of applications and scenarios has increased dramatically. According to different application scenarios and design systems, blockchain systems are generally divided into public chains, alliance chains and proprietary chains. in: [0003] Each node of the public chain can freely join and exit the network, and participate in the reading and writing of data on the chain. It is interconnected with a flat topology during operation, and there is no centralized server node in the network. [0004] Each node of the consortium chain usually has a corresponding entity organization, and can only join and exit the network after authorization. Various institutions and organizations form an alliance of stakeholders to jointly maintain the healthy operation...

AI Technical Summary

Problems solved by technology

[0008] (1) The overall system computing power of the alliance chain cannot be huge enough to resist the huge computing power attack from a node privately increased, making the POW consensus not suitable for the alliance chain

[0009] (2) Interest-related parties in the alliance chain may form interest alliances to erode the interests of some small institutions, and consensus mechanisms such as POS and DPOS are not suitable for alliance chains

The fault tolerance of this mechanism also brings complexity and long consensus time, which makes each transaction confirmation have to wait for a period of time. Compared with the second-level confirmation of the current centralized trading platform, it greatly affects the user experience.
