Scientists propose quantum proof-of-work consensus for blockchain By Cointelegraph

A team of researchers from universities in Australia and the United States, working in collaboration with quantum technology company BTQ, recently published research proposing a novel proof-of-work (PoW) scheme for blockchain consensus that relies on quantum computing techniques to validate consensus.

Dubbed “Proof-of-work consensus by quantum sampling,” the preprint research paper details a system that the authors claim “provides dramatic speedup and energy savings relative to computation by classical hardware.”
