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 .

Retricoin: Bitcoin based on compact proofs of retrievability

The verification time in our scheme is comparable to that of Permacoin and reasonable for all practical purposes. Regrievability to search form Skip to main content.

compct Showing of 8 extracted citations. 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.

The file can be constructed at any point of time from the users storing their respective segments untampered.

To guarantee the availability of an important but large file, we distribute the segments of the file among the users in the Bitcoin network. 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.

Showing of 28 references. 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.
