A working method of the consensus mechanism of an efficient blockchain with double-layer sharding

Abstract

The invention discloses a consensus mechanism and working method of a double-layer fragmented high-efficiency block chain. The consensus mechanism is based on a double-layer gossip topology network, including: full nodes, local full nodes, light nodes and micro nodes, full Nodes are responsible for the maintenance of node topology and sharding. They are elected and updated through the full node maintenance mechanism, and local full nodes are elected and updated through the local full node maintenance mechanism. They are responsible for transaction verification, transaction consensus, transaction storage, and ledger synchronization. The invention also proposes How this consensus mechanism works. A credible and incentivized node joining and updating mechanism proposed by the present invention ensures the stability, bandwidth capacity, and computing power of full nodes and partial full nodes, and reduces the impact on transaction confirmation speed. The consensus mechanism proposed by the present invention passes The "intra-chip autonomy, inter-chip collaboration" approach forms a divide-and-conquer distributed ledger system to ensure 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.
