Quantum‑classical blockchain testnet launches
Quipnetwork launched what it calls the first publicly available quantum‑classical blockchain testnet, integrating D‑Wave quantum annealing with classical hardware and attracting over 13,000 sign‑ups and experiments from MIT and Stanford researchers. The project’s social announcement emphasised early academic engagement and developer experimentation (X/Twitter).
A blockchain is a shared ledger, and a quantum annealer is a machine that searches huge numbers of possible answers for a good one. Quip.Network opened a public testnet on April 2 that tries to combine both. (prnewswire.com) Postquant Labs, the company building Quip.Network, said more than 13,000 people had signed up when it announced the launch from Casper, Wyoming. The company said the network was built in consultation with D-Wave Quantum and uses D-Wave’s Advantage2 annealing systems alongside central processing units and graphics processing units. (prnewswire.com) In plain terms, Quip is not asking miners to guess hashes the way Bitcoin does. Its mining task is an optimization puzzle based on the Ising model, which is a physics problem that can be handled by quantum annealing or by classical simulated annealing. (gitlab.com) That matters because D-Wave has spent the past year arguing that this kind of “proof of quantum work” can run blockchain functions on quantum hardware instead of only on classical machines. D-Wave’s March 2025 paper described a prototype blockchain spread across four cloud-based annealing quantum computers in Canada and the United States. (dwavequantum.com; arxiv.org) D-Wave said that prototype stayed stable across hundreds of thousands of quantum hashing operations, and its researchers argued that quantum hashing and proof of work could use a fraction of the electricity required by classical resources. Those claims come from D-Wave’s own research and have not yet become an industry standard. (arxiv.org; dwavequantum.com) Quip’s testnet is an attempt to move that idea from a lab demonstration into an open network where outside users can run nodes and submit workloads. Postquant Labs said researchers and developers can compete for QUIP token incentives by solving benchmark problems with quantum and classical hardware. (prnewswire.com) The code published for the experimental node shows how early the system still is. The repository says it is “not intended for production use,” has “no transactions, accounts, or other typical blockchain features,” and uses demonstration signatures rather than a production-secure signing system. (gitlab.com) Quip says the network is also meant to become a marketplace for shared quantum computing and a post-quantum security layer for existing blockchains. On its blog, the project describes the testnet as a trustless marketplace where users can submit workloads without owning or operating quantum hardware themselves. (quip.network) Independent coverage has treated the launch as an experiment rather than a finished chain. CoinDesk reported on April 2 that the testnet had drawn 13,000 sign-ups and early work from researchers at the Massachusetts Institute of Technology and Stanford, while Decrypt reported that the system is designed for Quip’s own network rather than for mining Bitcoin. (coindesk.com; decrypt.co) For now, the clearest fact is narrower than the marketing: Quip has launched a public test network that lets outsiders try blockchain-style mining tasks on quantum and classical hardware. Whether that becomes a useful blockchain, a shared compute market, or just a research test bed will depend on what those outside users find next. (prnewswire.com; gitlab.com)
