Problems solved by technology

However, if a miner maliciously hoards coins and mines, it will be easy to obtain the right to record. Therefore, it is very difficult for newly joined nodes and nodes with less computing resources to mine, and the probability of obtaining the right to record is small
[0006] It can be seen that the traditional blockchain consensus method based on workload proof will waste a lot of system computing power and the calculation cycle is long. friendly

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] In this embodiment, there are M=5 computing power statistics nodes S in the blockchain csn ={csn 1 ,csn 2 ,csn 3 ,csn 4 ,csn 5} and N=10 computing nodes S cn ={cn 1 ,cn 2 ,...,cn n ,...,cn 10}, the computing power statistics node is used to count the computing power of the computing node, the computing node is used to create blocks and connect blocks, and the computing power of the computing node is the size of computing resources that the computing node can provide.

[0028] like figure 1 As shown, the block chain consensus method based on improved workload proof and equity proof of the present invention includes the following steps:

[0029] Step 1: Computing power statistics node S in the blockchain csn ={csn 1 ,csn 2 ,csn 3 ,csn 4 ,csn 5} Calculate the computing power of each computing node to get the computing power...

Abstract

The invention relates to the technical field of computer block chains, and provides a block chain consensus method based on improved proof-of-work and proof-of-rights. Step 1: The computing power statistics node in the blockchain counts the computing power of the computing nodes; Step 2: The computing power statistics node evenly groups the computing power of all computing nodes in the blockchain, and adds blocks for each computing group Token value is assigned before the chain; Step 3: The user sends a request for storing data, sorts all computing groups according to the Token value from large to small, selects the top k computing groups to package the data into blocks, and selects the first to complete The calculation group that is packaged into a block operation is the master node, and the master node connects the block to the blockchain, and uses the protocol to broadcast messages to other nodes, and other nodes synchronize the state of the blockchain. The invention can save system computing power, shorten computing cycle, and avoid the problem of unfriendliness to nodes newly added to the network and nodes with less computing resources.

Description

technical field [0001] The invention relates to the technical field of computer block chains, in particular to a block chain consensus method based on improved proof-of-work and proof-of-rights. Background technique [0002] Blockchain is a database that maintains the same global state by nodes that do not trust each other. It has the advantages of decentralization, redundant storage, and data tamper-proof. Blockchain technology can realize data sharing between distrustful parties without the help of a third-party trusted organization. The reason why the blockchain can realize the anti-tampering feature of data is mainly because of the block-based chain structure and reasonable consensus mechanism. [0003] The consensus mechanism refers to the mechanism by which nodes that do not trust each other reach a consensus on the next step of legal behavior without the control of the central node. The common consensus mechanisms in the blockchain are Proof of Work (POW) and Proof ...
