The breakthrough raises concerns as both Ethereum and Bitcoin, securing over $600 billion, rely on elliptic curve cryptography.
While a 15-bit key is far weaker than the 256-bit keys used in production, the advance signals potential future risks to cryptocurrency security.
Thin order books and low trading volumes on Ethereum contrast with higher liquidity in Bitcoin markets, as traders monitor quantum advances and await responses from Vitalik Buterin, the Ethereum Foundation, and regulators.
A 15-bit key was just broken. How close are we to cracking the 256-bit keys securing trillions?
With 6.9 million Bitcoin exposed, are dormant assets a ticking time bomb for a quantum heist?
Can Bitcoin's decentralized governance upgrade its protocol before quantum computers can crack it?
Could 'digital salvage' rescue billions in dormant Bitcoin before quantum computers seize them?
Ethereum plans a 7-year quantum migration. Is this fast enough to outpace quantum breakthroughs?
As scientists self-censor attack details, are we entering a new era of cryptographic secrecy?
