【摘要】：利用区块链技术实现的去中心化的密码货币被誉为有史以来最成功的密码货币。用户以公钥作为账户地址,使交易具备匿名性,即隐私的可保护性。然而区块链上记录的交易信息,会给用户隐私带来潜在的泄露威胁;此外,为了防止重复花费,系统约定只有在目标区块之后又有k个后续区块产生才能确认该目标区块上的交易是有效的,这段等待后续区块生成的时间较长,大大降低了交易效率。针对以上问题,提出一种基于代理的密码货币支付系统模型,并给出了基于盲签名算法的实现方案,通过在支付阶段引入代理,缩短了交易确认时间,提高了交易效率,同时,更好地实现了用户的匿名性即隐私保护功能。
[Abstract]:Using block chain technology to the center of the password monetary history known as the most successful users on public key crypto currencies. As the account address, which deals with anonymity, privacy is the protectability. However, the transaction information recording block on the chain, will give the user privacy to reveal potential threat; in addition, in order to prevent double spending, the system agreed only in the target area after K follow-up to confirm the target block blocks the transaction is valid, the wait for the block to generate a longer time, greatly reduce the efficiency of the transaction. In view of the above problems, put forward a model of the payment system based on proxy password money, and presents the implementation scheme based on blind signature algorithm, by introducing the agent at the payment stage, shorten the transaction confirmation time, improve the efficiency of the transaction, at the same time, to achieve a better user anonymity Sex is the function of privacy protection.
