基于POW的区块链共识机制的改进
AN IMPROVED POW-BASED BLOCKCHAIN CONSENSUS MECHANISM
摘要
Abstract
The consensus mechanism based on proof of work(POW)is dominated by computing power in the process of looking for nonce,which wastes computing resources and memory,and there is a risk of 51%in computing power.To deal with this defect,an improved consensus mechanism IPOW(Improve Proof of Work)based on POW is proposed,which introduces control weight,encourage threshold,effective time and reward factor,and relational algorithms are given.The final accounting right R was obtained by controlling weight,etc.The experimental results show that compared with POW,IPOW consensus mechanism weakens the dominant role of computing power that plays in obtaining accounting right.The greater the control weight,the easier it is to obtain accounting right.It also reduces the probability of nodes in committing crime and reduces the phenomenon that the rich will get richer and richer.关键词
