Under a stronger assumption that the majority of computing power is controlled by the honest parties we construct a protocol for simulating any trusted functionality with guaranteed termination (i.e. that ...
We also believe that the "PoW-based distributed cryptography" can find several other applications in the peer-to-peer networks (we describe some of them). ...
