Google Quantum AI has shocked the crypto community after publishing research that drastically slashes the hardware and time requirements needed for quantum computers to break blockchain encryption.groundbreaking research that drastically reduces the timeline and hardware requirements for quantum computers to break the encryption securing Bitcoin, Ethereum, and other major blockchain networks.
Researchers from Google Quantum AI have revealed a massive leap forward in quantum decryption algorithms. For years, the crypto community has known that quantum computers would eventually pose a threat to the 256-bit elliptic curve discrete logarithm problem , which protects digital asset wallets. The general consensus was that such an attack would require millions of physical qubits. However, Google has successfully compiled quantum circuits capable of breaking ECDLP-256. Their algorithms require only 1,200 to 1,450 logical qubits.Google estimates these circuits can be executed on a superconducting quantum computer using fewer than 500,000 physical qubits in just a few minutes. Given that Bitcoin's average block time is roughly 10 minutes, a quantum computer capable of cracking a private key in under 9 minutes opens the door to devastating"mempool attacks." A bad actor monitors the network for broadcast transactions."We thought quantum attacks could take months, meaning transactions were safe and only 1/3 of BTC were at risk," Project Eleven explained."Now a quantum computer could crack private keys in 9 mins... Mempool attacks just became real." The researcher also noted that, based on Google's data, quantum computers will soon be capable of breaking into the top 1,000 Ethereum wallets in less than 9 days.Ethereum researcher Justin Drake, who joined the Google Quantum AI paper as a late co-author, weighed in on the developments, describing the dual breakthroughs as a"monumentous day for quantum computing and cryptography.""From now on, assume state-of-the-art algorithms will be censored," Drake cautioned."There may be self-censorship for moral or commercial reasons, or because of government pressure. A blackout in academic publications would be a tell-tale sign." Finnovex North Africa 2026: Catalyzing Egypt’s Fintech Revolution Through Smart Finance and Regulatory Transformation
