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

A startup working with quantum computing firm D-Wave says it has constructed a brand new form of crypto mining testnet that replaces Bitcoin-style hashing with optimization issues that quantum methods might remedy extra effectively.

On Thursday, Postquant Labs launched what it described as the primary publicly accessible quantum-classical blockchain testnet. The community, referred to as Quip Community, lets members mine cryptocurrency utilizing quantum computer systems, together with standard CPUs and GPUs. As an alternative of competing to resolve the hash-based calculations utilized in Bitcoin mining, members compete to resolve optimization issues.

“With Bitcoin, you are fixing what’s often known as the hashcash downside,” Richard Carback, CTO and co-founder of Postquant Labs, informed Decrypt. “What we’re doing is we’re trying to find a selected Ising mannequin that matches a selected vitality goal. It is an issue that is way more tough for classical computer systems to resolve, however very, very achievable for quantum computer systems to do in a quicker capability.”

Launched in 2024, Postquant Labs develops quantum computing software program and protocols. The corporate partnered with Burnaby, Canada-based D-Wave Techniques to run components of Quip Community’s Proof-of-Work course of on D-Wave’s quantum annealing processors.

Quip Community asks miners to resolve an Ising mannequin optimization downside. The Ising mannequin optimization is a mathematical framework through which an issue is mapped to an Ising‑sort vitality operate, and fixing the issue corresponds to discovering the bottom‑vitality association of a system of interacting binary variables.

Profitable miners earn QUIP tokens. These tokens are meant to pay for time on quantum computer systems related to the community, the corporate stated. Colton Dillion, CEO and co-founder of Postquant Labs, in contrast the mannequin to Bittensor’s TAO community, which rewards customers for contributing AI fashions and computing sources.

“We’re doing one thing very comparable, besides you are mining the QUIP token, which can in the end be used to hire time on different quantum computer systems,” Dillion informed Decrypt.

Postquant stated the mannequin might additionally scale back the vitality required to mine a block. Bitcoin mining has confronted scrutiny over its electrical energy use as a result of it depends on giant numbers of machines performing steady computations.

“For one block, we count on that it takes about 13 watts to mine a block on a quantum laptop,” Dillion stated. “That is about as a lot as your gentle bulb goes to make use of in an hour.”

Quantum {hardware} stays far much less accessible than standard mining tools, nonetheless. Conventional GPUs are broadly accessible and used for varied functions—together with gaming and crypto mining—whereas entry to quantum computing methods is proscribed to company analysis labs and universities.

Trevor Lanting, chief improvement officer at D-Wave Techniques, stated the corporate views quantum processors as accelerators for particular workloads, reasonably than replacements for classical {hardware}. He pointed to industrial makes use of of D-Wave’s quantum annealing methods in enterprise operations and logistics.

“We now have prospects fixing operations issues and working enterprise operations with our Leap platform at the moment,” he informed Decrypt. “I don’t see the trade going by a sudden step change. Completely different applied sciences are commercializing at totally different charges.”

Past questions of price and entry, nonetheless, quantum computing additionally carries long-term safety implications.

Researchers are more and more warning about “Q-Day,” the purpose when a quantum laptop turns into highly effective sufficient to interrupt the public-key cryptography used throughout the web. Techniques that depend on elliptic curve cryptography—together with Bitcoin and Ethereum—might develop into weak if quantum machines are capable of derive personal keys from public ones.

“Q-Day is getting plenty of consideration as a result of many individuals see it as a degree the place the trade reaches a sure functionality stage,” Lanting stated. “I’m extra enthusiastic about quantum chemistry for gate-model functions.”

Postquant stated it additionally plans to make use of a future model of the community’s system to benchmark progress towards breaking elliptic curve cryptography, the mathematical system that secures Bitcoin wallets.

“Maintain mining Bitcoin,” Carback informed Decrypt. “You must in all probability use one in every of our post-quantum wallets, and we’ll hold you up to date on the progress.”
