What to know:
- Google said it had achieved a verifiable "quantum advantage" with its Willow chip completing a calculation that would take classical supercomputers thousands of times longer.
- The reported breakthrough may reignite a debate in the cryptocurrency community over the possible detrimental effects that quantum computing could have on Bitcoin.
- While quantum computing could one day challenge Bitcoin’s cryptographic foundations, most experts say that reality remains far off.
Google said it had achieved a verifiable "quantum advantage" with its Willow chip completing a calculation that would take classical supercomputers thousands of times longer.
The reported breakthrough may reignite a debate in the cryptocurrency community over the possible detrimental effects that quantum computing could have on Bitcoin, whose operation and security is built on cryptographic methods which quantum computing could potentially challenge.

The chip reportedly simulated quantum chaos in just two hours by measuring Out-of-Time-Order Correlators (OTOCs), a key benchmark for tracking the unpredictable behavior of particles.
Researchers say the achievement moves quantum computing closer to practical applications, such as Hamiltonian learning, where quantum machines could help model complex molecular structures beyond the reach of today’s tools.
For the crypto world, the breakthrough is noteworthy but not alarming. While quantum computing could one day challenge Bitcoin’s cryptographic foundations, most experts say that reality remains far off.
"There’s no evidence today that any computer, even a classified one, can break modern cryptography," Kostas Kryptos Chalkias, co-founder and chief cryptographer of Mysten Labs, told CoinDesk in a recent interview. “We’re at least 10 years away from that.”
Google parent company Alphabet's (GOOG) shares enjoyed a 1.5% bump following the publication of its research, before pulling back to its prior level. At the time of writing, GOOG sits just above $253, 0.7% higher on the day.
Bitcoin experienced a minor boost concurrently with GOOG's, climbing 0.7% to just under $109,000 falling back. BTC is 4% lower in the last 24 hours at about $108,150 at the time of writing, according to CoinDesk data.

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.
What to know:
- KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
- This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
- Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
- Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
- Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.

Ethereum Foundation makes post quantum security a top priority as new team forms
EF researcher Justin Drake says a new post-quantum team will drive wallet safety upgrades, research prizes and test networks as quantum timelines shorten.
What to know:
- The Ethereum Foundation has elevated post-quantum security to a top strategic priority, forming a dedicated Post Quantum team led by Thomas Coratger with support from leanVM cryptographer Emile.
- Researcher Justin Drake said Ethereum is shifting from background research to active engineering, including biweekly developer sessions on post-quantum transactions and multi-client post-quantum consensus test networks.
- The foundation is backing new cryptography with funding and outreach, launching two $1 million prizes, planning post-quantum community events and education, and stressing that blockchains must prepare early for quantum threats despite their long-term nature.
