Bilayer sliced high-efficiency block chain consensus mechanism and working method thereof

Abstract

The invention discloses a bilayer sliced high-efficiency block chain consensus mechanism and a working method thereof. The consensus mechanism is based on a bilayer gossip topology network, and comprises a full node, a local full node, a light node and a micro node, wherein the full node is in charge of node topology and slice maintenance and is elected and updated through a full node maintenancemechanism; and the local full node is elected and updated through a local full node maintenance mechanism and is in charge of transaction validation, transaction consensus, transaction storage and account synchronization. The invention also provides a working method for the consensus mechanism. A credible and incentive node joining and updating mechanism is provided, the stability, the bandwidth capability and the computing capability of the full node and the local full node are ensured, and the impacts on a transaction confirmation speed are reduced. The consensus mechanism proposed by the invention forms a divide-and-conquer distributed account system by means of intra-slice autonomy and inter-slice collaboration to ensure to consider decentralization, scalability and security.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a consensus mechanism and working method of a two-layer fragmented high-efficiency block chain. Background technique [0002] At present, there are several major types of blockchain consensus mechanisms: POW, POS, DPOS, and PBFT. POW proof of work is the familiar Bitcoin mining. By calculating a random number that satisfies the rules, it obtains the right to bookkeeping this time, sends out the data that needs to be recorded in this round, and stores it together after verification by other nodes in the entire network. Complete decentralization can be achieved, and nodes can enter and exit freely, but mining causes a lot of waste of resources, and the cycle for reaching consensus is long, which is not suitable for commercial applications. Proof of POS rights and interests, an upgraded consensus mechanism of POW, reduces the difficulty of mining in proportion to the number an...

Problems solved by technology

[0005] 1) In the wide area network environment, the volatility of nodes is strong, and the fluctuation of the voting ability n of the whole network is also increased. This may cause the system to be unable to find events that satisfy 2n / 3 voting consensus for a long time, so that consensus cannot be reached;

[0006] 2) Affected by factors such as node stability, processing capacity, and bandwidth, the ability of different nodes to process events varies greatly

If there are a large number of weaker nodes participating in voting in the system, it will also cause the system to be unable to reach a consensus for a long time;

[0007] 3) In the wide area network environment, frequent fluctuations of nodes may cause nodes to be divided into multiple subnets

At this time, if the scale of the subnet is small, it is easy for malicious nodes to generate two famous witness events in the same round, resulting in double-spending transactions;

[0008] 4) As the scale of the system increases, more and more synchronization information is received by the nodes. It is foreseeable that the throughput rate of the system will decrease with the increase of the number of nodes.
