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 .

Showing of 28 references. Retricoin is more efficient than the existing Permacoin scheme  in terms of storage overhead and network bandwidth required to broadcast the proof to the Bitcoin network.
The verification time in our scheme is comparable to that of Permacoin and reasonable for all practical purposes. We also design an algorithm to let the miners in a group or pool mine collectively.
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.

Every user retgievability 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.
The generation of the proof-of-work in Bitcoin requires retrifvability amount of computing resources. The file can be constructed at any point of time from the users storing their respective segments untampered. Pseudorandomness Antivirus software Aggregate data.

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