Extract from Abstract


We propose Mixcoin, a protocol to facilitate anonymous payments in Bitcoin and similar cryptocurrencies. We build on the emergent phenomenon of currency mixes, adding an accountability mechanism to expose theft. We demonstrate that incentives of mixes and clients can be  aligned  to  ensure  that  rational  mixes  will  not  steal.  Our  scheme  is efficient and fully compatible with Bitcoin. Against a passive attacker,our  scheme  provides  an  anonymity  set  of all other  users  mixing  coins contemporaneously.  This  is  an  interesting  new  property  with  no  clear analog in better-studied communication mixes. Against active attackers our scheme offers similar anonymity to traditional communication mixes.
