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 .

Every user who wants to mine Bitcoins must store a considerable portion of this file and prove her storage to other peers in the network using proofs of retrievability.


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.

Store, Forget, and Check: However, this huge amount of energy is wasted as one cannot make something useful out of it. References Publications referenced by proors paper. The generation of the proof-of-work in Bitcoin requires large amount of computing resources.

The file can be constructed at any point of time from the users storing their respective segments untampered. The verification time in our scheme is comparable to that of Permacoin and reasonable for all practical purposes.
