Regulatory Bitcoin privacy-preserving mixing service

With the deepening of research on Bitcoin privacy protection, Bitcoin, a new type of digital currency, has become more difficult to regulate. A Bitcoin privacy protection confusion scheme with regulatory RBmix is proposed for this problem. The model of RBmix uses a fair blind signature algorithm and introduces trusted third parties with regulatory, anonymity, scalability, Bitcoin compatibility, and anti-DoS aggression. Experimental results show that the RBmix protocol has good scalability and execution efficiency.
