Scientists propose quantum proof-of-work consensus for blockchain
Boson sampling was once considered a problem looking for a solution. Now, it might be the bridge that brings quantum computing to the blockchain. 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. Our new paper on using NISQ-era quantum sampling problems in proof-of-work blockchain consensus algorithms. In collaboration with @BTQ_Tech.https://t.co/MKAB2czqSk — Peter Rohde (@drpeterrohde) June 1, 2023 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." According to the researchers, current algorithms for solving PoW consensus puzzles are slow and require a significant am...
