Startup lets researchers mine blockchain tasks on a quantum computer for the first time

Built with advice and hardware access from D-Wave, the testnet has drawn 13,000 sign-ups and early work from six research teams, but remains an experimental environment rather than a live mainnet. What to know : Postquant Labs has launched a blockchain testnet that lets quantum processors, GPUs and CPUs work side by side so researchers can test whether quantum computing offers real advantages for blockchain tasks. Built with advice and hardware access from D-Wave, the testnet has drawn 13,000 sign-ups and early work from six research teams, but remains an experimental environment rather than a live mainnet. The project aims to see if quantum machines can deliver better speed, solution quality and energy efficiency than classical systems for optimization problems, while acknowledging that any mainnet launch depends on proving genuine quantum advantage and market demand.(Coindesk)
