基于空间量证明的共识算法综述

Summary of consensus algorithm based on proof of space

在区块链系统中,空间量证明被认为是比工作量证明更绿色、更经济的选择。与工作量证明不同,空间量证明将存储作为投入的资源,以此有效地避免资源的集中化,提高不同矿工之间挖矿的公平性。文章将空间量证明作为主要论述对象,列举了区块链中现有的物理资源消耗型证明技术,对其中以存储量作为消耗资源的证明技术进行展开,阐述了空间量证明的当前研究现状,对将基于空间量证明的共识算法与区块链结合的难点进行分析并总结现有的解决方法。

In the blockchain system,proof of space is considered a greener and more economical choice than proof of work.Different from proof of work,the proof of space takes the storage as the consuming resource,so as to effectively avoid the concentration of resources and improve the fairness of mining among different miners.Summary takes proof of space as the main object,listing the existing proof technology of physical resource consumption in blockchain,detailedly discussing the proof technologies which take storage as consuming resource,generalizing current research status of proof of space,analyzing the difficulty of applying the consensus algorithm based on proof of space in blockchain and summarizing the current solution.
