Embodiment

[0052] see figure 1 , the contribution degree can be regarded as the user utility of a miner. From a social point of view, this is a design idea to suppress selfish behavior. Once miners often participate in the creation of blocks, they will get a stronger contribution. Otherwise, his contribution will be very low. With a strong contribution, the miner can easily access blocks from the network.

[0053] The flow chart of the DCM scheme is as follows figure 1 As shown, an incentive method in a blockchain consensus mechanism includes the following steps:

[0054] Step 1. At the beginning, each node in the network is assigned an initial contribution (C 0 ), the initial contribution gives each node a chance to access the block;

[0055] Step 2. As we all know, each node has the potential to become a miner in the blockchain network. When a node is selected as a miner, its contribution will be re-evaluated and updated according to its behavior in block creation ;

Abstract

An incentive method in a blockchain consensus mechanism, including the following steps: Step 1, at the beginning, each node in the network is assigned an initial contribution degree ( C 0 ), the initial contribution gives each node a chance to access the block; step 2, when a node is elected as a miner, its contribution will be re-evaluated and updated along with its behavior in block creation; When the node is selected as a miner, the evaluation of its contribution depends on two factors, namely the activity factor and the reward and punishment factor; step 3, adopt three punishment strategies to suppress selfish miners, P1: when C i < C 0 when M i block cannot be accessed; P2: when A i <c 0 when M i Block cannot be accessed; P3: when RP i <c 0 when M i Blocks cannot be accessed. Since malicious miners are more terrifying, the miner team should set M i Excluded; it has the characteristics of high operating efficiency and high reliability.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to an incentive method in a block chain consensus mechanism. Background technique [0002] Blockchain first attracted attention in 2008 as the underlying technology of Bitcoin, but today it is widely used in various applications and creates global market value. Through data encryption, time stamp, consensus mechanism and smart contract, blockchain can realize decentralized credit peer-to-peer transactions, coordination and collaboration in distributed systems, thus solving the problems of high cost, low efficiency and insecure data storage of centralized institutions provide the solution. [0003] Blockchain technology is considered to be the fifth disruptive computing paradigm after mainframes, personal computers, the Internet, and mobile social networking, and the fourth milestone in the history of human credit evolution after blood relative credit, precious meta...
