A Fistful of Bitcoins: Characterizing Payments Among Men with No Names
Bitcoin has the unintuitive property that while the ownership of money is implicitly anonymous, its flow is globally visible. In this paper we explore this unique...

Secure Multiparty Computations on Bitcoin
In this work, we propose to use Bitcoin to design fully decentralized protocols that are secure even if no trusted third party is available.
