RSCoinJoin:基于环签名的混币方案

RSCOINJOIN:MIXED-CURRENCY SCHEME BASED ON RING SIGNATURE

针对混币方案CoinShuffle中完成混币交易耗时较多的问题,提出一种基于环签名的混合方案。用户公告参与混币的输入、输出地址并由最后一个用户将地址集合发布到网络中;用户确认自己的输出地址是否在集合中,如果存在则发起混币交易,并对交易进行签名,直到最后一个用户签名后将交易发布。实验结果表明,RSCoinJoin在参与混币用户数是50时,完成一笔交易的平均时间为2 s,比现有的混合方案速度更快。

In order to solve the problem that CoinShuffle takes much time to complete the mixed-currency transaction,a mixed-currency scheme based on ring signature is proposed.The user announced the input and output addresses of the mixed currency,and the address set was published on the network by the last user.The user confirmed whether his output address was in the collection,initiated a mixed-currency transaction if it existed,and signed the transaction until the last user signed and published the transaction.The experimental results show that when the number of users of RSCoinJoin is 50,the average time to complete a transaction is 2 second,which is faster than the existing hybrid scheme.
