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.

Key words: Bitcoin, privacy-preserving, regulatory, fair blind signature
