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 – Smith + Crown

Multi authority attribute based encryption against data integrity and scalability issues in cloud data services A. Every user who wants to mine Bitcoins must store a considerable portion of this file and prove her storage to other prooofs in the network using proofs of retrievability.

The generation of the proof-of-work in Bitcoin requires large amount of computing resources. ShahMary BakerJeffrey C. We also design an algorithm to let the miners in a group or pool mine collectively.


Retricoin: Bitcoin based on compact proofs of retrievability

However, this huge amount of energy is wasted as one cannot make something useful out of it. Retricoin is more efficient than the existing Permacoin scheme [23] in terms of storage overhead prooofs network bandwidth required to broadcast the proof to the Bitcoin network.
