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 .

We also design an algorithm to let the miners in a group or pool mine propfs. 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.


To guarantee the availability of an important but large file, we distribute the segments of the file among the users in the Bitcoin network. The generation of the proof-of-work in Bitcoin requires large amount of computing resources. However, this huge amount of energy is wasted as one cannot make something useful out of it.
