Problems solved by technology

[0006] In the existing technology, there is a kind of scheme that mixes POW and POS consensus, but their essence is to design a unified evaluation standard, so that nodes with large computing power and nodes with large rights and interests compete to produce blocks in the same dimension; in addition There is also a class of solutions to improve the efficiency of the blockchain, such as sharding, lightning network, etc. They do not directly optimize the blockchain itself, but propose a layer2 level optimization, and such optimization sacrifices certain at the expense of security

Embodiment Construction

[0045] The purpose and effects of the present invention will become clearer by describing the present invention in detail according to the accompanying drawings and preferred embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0046] The hybrid consensus method combining POW and POS of the present invention includes two block chains in the consensus method, the first chain adopts POW proof consensus to generate blocks, and the second chain uses the historical data of the first chain as a basis, adopts The POS consensus generates blocks and runs business logic.

[0047] The first chain can choose to run a brand new POW blockchain or an existing POW blockchain, thereby reducing development costs and energy consumption.

[0048] The second chain is the main body of this solution, and all business logic (such as smart contracts) provided to users are implemented on ...

Abstract

The invention discloses a hybrid consensus method combining POW and POS. The consensus method comprises two block chains, a first chain adopts a POW consensus output block, a second chain adopts a POSconsensus output block based on historical data of the first chain and operates business logic, and the consensus process comprises three parts of address mapping, computing power mapping and competition output block. According to the method, the characteristics of high safety and addition without auditing of the POW algorithm are combined; the method also has the characteristics of short POS algorithm block output interval and less computing resource occupation, and can bear more business logics and provide quicker response service; on the premise of ensuring the security of the blockchain,the high efficiency of the blockchain can be ensured.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a hybrid consensus method and consensus equipment combining POW and POS. Background technique [0002] Blockchain is a new type of distributed system technology, and the consensus mechanism is an extremely important part of it. Through the consensus mechanism, each node in the distributed system can reach a consistent understanding of the data, thereby ensuring the consistency of data storage. With the development of blockchain technology, a variety of consensus mechanisms have emerged, among which the POW consensus mechanism and the POS consensus mechanism are representative. [0003] The POW consensus mechanism mainly confirms the block by calculating the block hash that meets the difficulty requirements. So far, to obtain a suitable block hash can only be obtained through an exhaustive algorithm, so it needs to consume a lot of computing resources. Since no one or organ...
