Delegated Proof of Reputation: a novel Blockchain consensus
This addresses the problem of restricted scalability in blockchain networks for developers and users, though it appears incremental as an improvement over Delegated Proof of Stake.
The paper tackles the scalability limitations of blockchain consensus mechanisms by introducing Delegated Proof of Reputation, which replaces coinstaking with a reputation ranking system based on PageRank, NCDawareRank, and HodgeRank, resulting in a scalable, secure, and acceptably decentralized protocol.
Consensus mechanism is the heart of any blockchain network. Many projects have proposed alternative protocols to improve restricted scalability of Proof of Work originated since Bitcoin. As an improvement of Delegated Proof of Stake, in this paper, we introduce a novel consensus, namely, Delegated Proof of Reputation, which is scalable, secure with an acceptable decentralization. Our innovative idea is replacing pure coinstaking by a reputation ranking system essentially based on ranking theories (PageRank, NCDawareRank and HodgeRank).
