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.

Technical Perspective: Catching Lies (and Mistakes) in Offloaded Computation
The system described in "Pinocchio: Nearly Practical Verifiable Computation" refines an important theoretical advance by Gennaro et al. Together, these two works represent...
