Block chain bottom consensus mechanism and block chain system based on block chain bottom consensus mechanism

Abstract

The invention discloses a block chain bottom consensus mechanism and a block chain system based on the consensus mechanism. The block chain bottom consensus mechanism comprises a consensus network structure, participants, a first protocol, a second protocol, and a third protocol; the consensus network structure is used for providing a carrier for transmitting and synchronizing data; the participants are used for participating in data storage and evaluation in the consensus network structure; the first protocol is used for voting for specific participants based on the rotate account sub-protocol and generating a new block when equal probability rotating; the second protocol is used for providing group voting or estimate for all participants holding tokens or digital shares based on the group estimate consensus sub-protocol and generating an extra new block; and the third protocol is used for connecting with each consensus mechanism network based on the gear consensus routing sub-protocol. According to the invention, the characteristics of the block chain data structure and the point to point network communication are combined to realize the secure, efficient, decentralized and application scenario flexible data synchronization consensus.

Description

technical field [0001] The present invention relates to the field of block chains, in particular to a block chain underlying consensus mechanism and a block chain system based on the consensus mechanism. Background technique [0002] Consensus mechanism refers to the algorithm for blockchain transactions to reach a distributed consensus. [0003] Blockchain is a decentralized distributed ledger system, which can be used to register and issue digital assets, property certificates, points, etc., and transfer, pay and trade in a peer-to-peer manner. Compared with the traditional centralized ledger system, the blockchain system has the advantages of being completely open, tamper-resistant, and preventing multiple payments, and does not rely on any trusted third party. However, due to the high network delay in the peer-to-peer network, the sequence of transactions observed by each node cannot be completely consistent. Therefore, the blockchain system needs to design a mechanism...

Problems solved by technology

[0007] However, the disadvantage of the current consensus mechanism POW is that: Bitcoin has attracted most of the computing power in the world, and it is difficult for other blockchain applications that use the POW consensus mechanism to obtain the same computing power to ensure their own security; waste of resources; the cycle of reaching a consensus is long, which is not suitable for commercial applications; due to the concentration of computing power, there is a risk of 50% attack to a certain extent

The advantage of this mechanism is that it is not as expensive as POW, but it also has many disadvantages: 1) There is no specialization, and participants with rights and interests may not want to participate in bookkeeping; 2) It is easy to generate forks and need to wait for multiple confirmations; 3 ) is never final and needs a checkpoint mechanism to compensate for finality

[0009] However, the disadvantages of the current consensus mechanism POS are: mining is still required, which essentially does not solve the pain points of commercial applications; due to the centralization of token holdings, it causes centralization to a certain extent

[0011] However, the disadvantage of the current consensus mechanism DPOS is that: the willingness of token holders to vote is not strong or the voting is centralized, resulting in a certain degree of centralization

[0018] However, the disadvantages of the current consensus mechanism PBFT are: low fault tolerance rate and poor flexibility. If more than 1 / 3 of the nodes do evil, the system will crash. Nodes cannot be dynamically added, and it is only applicable to alliance chain or private chain scenarios.

[0019] In summary, the existing blockchain consensus mechanism has problems such as low consensus efficiency, consumption and waste of computing resources, 50% attack risk, and application scenario limitations.
