摘要

提出了去中心化信贷系统，并给出了其构造应用。通过扩展基于区块链的“数字货币商品”的交易结构、扩展共识协议的功能和增加特定账户的方法，来构造去中心化信贷系统。同时，将去中心化信贷系统应用到基于区块链的PKI增强与监督系统IKP，从而使IKP系统在运行中不需要全局基金，并且通过在去中心化信贷系统中引入分层“虚拟货币商品”供应量调节机制缓解基于区块链的“数字货币商品”在“虚拟货币商品”供给量上难以调节的问题，实现精确调节“虚拟货币商品”供应量。

Abstract

A decentralized credit system was proposed and its construction application was given.Decentralized credit system could be constructed by expanding the transaction structure of “digital currency commodity” based on block chain

expanding the function of consensus protocol and adding specific accounts.Also

the decentralized credit system was applied to the PKI enhancement and supervision system IKP so that IKP system did not need global fund in operation.Moreover

by introducing the hierarchical “virtual currency commodity” supply adjustment mechanism in the decentralized credit system to alleviate the difficulty of regulating the “virtual currency commodity” supply of “digital currency commodity” based on block chain

the precise “virtual currency commodity” supply regulation can be achieved.
