Por proofs of retrievability
WebOne of possible alternatives for useful Proof-of-Work schemes, Permacoin, is using non-interactive proofs of a static dataset retrievability thus providing a mechanism to store a huge dataset being spread across miners collectively. In this paper we present a new consensus protocol for Bitcoin-like peer-to-peer systems, where the right to ...
