Quantum-Powered Crypto Mining Is Here—But It Won't Help You Mine Bitcoin

A startup moving with quantum computing institution D-Wave says it has built a caller benignant of crypto mining testnet that replaces Bitcoin-style hashing with optimization problems that quantum systems whitethorn lick much efficiently.

On Thursday, Postquant Labs launched what it described arsenic the archetypal publically disposable quantum-classical blockchain testnet. The network, called Quip Network, lets participants excavation cryptocurrency utilizing quantum computers, on with accepted CPUs and GPUs. Instead of competing to lick the hash-based calculations utilized successful Bitcoin mining, participants vie to lick optimization problems.

“With Bitcoin, you're solving what's known arsenic the hashcash problem,” Richard Carback, CTO and co-founder of Postquant Labs, told Decrypt. “What we're doing is we're searching for a peculiar Ising exemplary that matches a peculiar vigor target. It's a occupation that's overmuch much hard for classical computers to solve, but very, precise achievable for quantum computers to bash successful a faster capacity.”

Launched successful 2024, Postquant Labs develops quantum computing bundle and protocols. The institution partnered with Burnaby, Canada-based D-Wave Systems to tally parts of Quip Network’s Proof-of-Work process connected D-Wave’s quantum annealing processors.

Quip Network asks miners to lick an Ising model optimization problem. The Ising exemplary optimization is simply a mathematical model successful which a occupation is mapped to an Ising‑type vigor function, and solving the occupation corresponds to uncovering the lowest‑energy statement of a strategy of interacting binary variables.

Successful miners gain QUIP tokens. Those tokens are intended to wage for clip connected quantum computers connected to the network, the institution said. Colton Dillion, CEO and co-founder of Postquant Labs, compared the exemplary to Bittensor’s TAO network, which rewards users for contributing AI models and computing resources.

“We're doing thing precise similar, but you're mining the QUIP token, which volition yet beryllium utilized to rent clip connected different quantum computers,” Dillion told Decrypt.

Postquant said the exemplary could besides trim the vigor required to excavation a block. Bitcoin mining has faced scrutiny implicit its energy usage due to the fact that it relies connected ample numbers of machines performing continuous computations.

“For 1 block, we expect that it takes astir 13 watts to excavation a artifact connected a quantum computer,” Dillion said. “That's astir arsenic overmuch arsenic your airy bulb is going to usage successful an hour.”

Quantum hardware remains acold little accessible than accepted mining equipment, however. Traditional GPUs are wide disposable and utilized for assorted purposes—including gaming and crypto mining—while entree to quantum computing systems is constricted to corporate probe labs and universities.

Trevor Lanting, main improvement serviceman astatine D-Wave Systems, said the institution views quantum processors arsenic accelerators for circumstantial workloads, alternatively than replacements for classical hardware. He pointed to commercialized uses of D-Wave’s quantum annealing systems successful concern operations and logistics.

“We person customers solving operations problems and moving concern operations with our Leap level today,” helium told Decrypt. “I bash not spot the manufacture going done a abrupt measurement change. Different technologies are commercializing astatine antithetic rates.”

Beyond questions of outgo and access, however, quantum computing besides carries semipermanent information implications.

Researchers are progressively informing astir “Q-Day,” the constituent erstwhile a quantum machine becomes almighty capable to interruption the public-key cryptography utilized crossed the internet. Systems that trust connected elliptic curve cryptography—including Bitcoin and Ethereum—could go susceptible if quantum machines are capable to deduce backstage keys from nationalist ones.

“Q-Day is getting a batch of attraction due to the fact that galore radical spot it arsenic a constituent wherever the manufacture reaches a definite capableness level,” Lanting said. “I americium much excited astir quantum chemistry for gate-model applications.”

Postquant said it besides plans to usage a aboriginal mentation of the network’s strategy to benchmark advancement toward breaking elliptic curve cryptography, the mathematical strategy that secures Bitcoin wallets.

“Keep mining Bitcoin,” Carback told Decrypt. “You should astir apt usage 1 of our post-quantum wallets, and we'll support you updated connected the progress.”
