In a proof-of-retrievability system, a data storage center must prove to a verifier that he is actually storing all of a client’s data. The central. Compact Proofs of Retrievability. Contribute to foodotbar/Compact-Proofs-of- Retrievability development by creating an account on GitHub. A proof of retrievability (POR) is a compact proof by a file system (prover) to a client of a proof. Its main advantage is that, due to the underlying block integrity .

The verification time in our scheme is comparable to that of Permacoin and reasonable for all practical purposes. In this paper, we propose a scheme called Retricoin which replaces the heavy computational proof-of-work of Bitcoin by proofs of retrievability that have practical benefits. Retricoin is more efficient than the existing Permacoin scheme [23] in terms of storage overhead and network bandwidth required to broadcast the proof to the Bitcoin network.
