Retricoin: Bitcoin based on compact proofs of retrievability

  title={Retricoin: Bitcoin based on compact proofs of retrievability},
  author={Binanda Sengupta and Samiran Bag and Sushmita Ruj and Kouichi Sakurai},
Bitcoin [24] is a fully decentralized electronic cash system. 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. 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. To guarantee the availability of an important but large file, we distribute… CONTINUE READING
