Proof of Reputation. (arXiv:2302.06966v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
We present the new mining protocol Proof-of-Reputation (PoR) for
decentralized Proof-of-Work (PoW) blockchains, in particular for Bitcoin. PoR
combines the classical PoW with the new ingredient of cryptographic reputation.
The same level of security compared to pure PoW can be achieved with a
significant energy consumption reduction (of the order of 30\%) for the same
security level. The proper implementation of a decentralized reputation
protocol is suitable with an extra layer of mining security: Certified Mining.
