Proof of Continuous Work for Reliable Data Storage over Permissionless Blockchain

Published in IEEE Internet of Things Journal, 2021

In this paper, we first design a variant consensus algorithm named proof of continuous work (PoCW) with a storage-related incentive mechanism. Miners can accumulate mining advantage by continuously submitting proofs of storage. Then we present a hash ring-based data allocation algorithm using the blockchain’s state. Combined with both of them, we build a reliable blockchain-based storage system without relying on any third parties.
