A proof-of-randomness (PoR) protocol could be a fair and low energy-cost
consensus mechanism for blockchains. Each network node of a blockchain could
use a true random number generator (TRNG) and hash algorism to fulfil the PoR
protocol. In this whitepaper, we give the consensus mechanism of the PoR
protocol, and show how it could make the random numbers unforgeable. The PoR
protocol could generate a blockchain without any competition of computing power
or stake of cryptocurrency. Besides, we give some advantages of integrating
quantum random number generator (QRNG) chips in hardware wallets, and also
discuss the route to cooperate with quantum key distribution (QKD) technology.Comment: 7 pages, 1 figur
