Google Quantum AI don reduce di threshold for quantum attack for Bitcoin: BTC/ETH post-quantum rush
Google Quantum AI team dey warn say Bitcoin quantum security fit scatter with less quantum resources than people bin think before. For new white paper, researchers talk say quantum computers fit crack the elliptic-curve cryptography wey BTC and ETH dey use sooner and with way fewer qubits than old estimates.
Paper talk say for some scenarios around 1,200–1,450 high-quality qubits fit do the work, instead make dem need hundreds of thousands physical qubits. For Bitcoin, risk dey because of transaction-level exposure window: if strong quantum computer exist, attackers fit reconstruct private key from the short-time visible public key, make dem fit carry out "on-spend" style attack.
For Ethereum, threat dey more structural because public keys dey visible after account do first transaction, so "at-rest" compromises fit happen. Report still mention estimated probability say public-key-to-private-key recovery fit happen by 2032 and discuss mass-compromise scenario for top accounts.
Google talk say dem dey target move their authentication systems to post-quantum cryptography by 2029, but wetin this mean for Bitcoin quantum security and wider crypto infrastructure clear: wallets, validators, and payment providers fit face pressure to upgrade earlier make dem no exposed during transition.
Market takeaway for traders: this one fit push BTC/ETH security repricing, fit cause short-term volatility around "quantum risk" headlines and long-term focus on post-quantum migration readiness across networks like SOL.
Bearish
For BTC and ETH, di tori tok sey quantum-capable attackers fit need less qubits pass wetin many people dey talk, mak di timeline for cryptographic risk dey feel nearer. Dat dey increase long-term security uncertainty wey people dey perceive, fit put pressure for sentiment and raise risk premiums. For short term, di headline-driven “quantum attack” talk fit cause volatility as traders dey reprice their security assumptions. But because di paper still dey hypothetical and e depend on future quantum hardware progress, di impact na more about narrative risk and discounting resilience than immediate deterministic sell signal—so di bias na bearish but e no guaranteed say e go dey trend straight down.
