Galaxy Digital's Alex Thorn says Bitcoin developers and researchers have reached a consensus that Satoshi Nakamoto's original coins should remain untouched to preserve core ownership rules. Quantum threat is acknowledged but deemed distant due to distributed address structure.
ARK Invest and Unchained's joint white paper reveals that about 35% of Bitcoin's supply is potentially vulnerable to quantum attacks, but current quantum computing is far from a real threat, and any danger would emerge gradually across five phases.
A 2010 forum reply from Satoshi Nakamoto has resurfaced, showing he believed Bitcoin could migrate to stronger cryptography if quantum threats emerged gradually. The discussion has regained attention as quantum computing advances accelerate.
BTQ Technologies has launched Bitcoin Quantum, a permissionless fork testnet that replaces ECDSA with ML-DSA and increases block size to 64 MiB. The clean-slate fork aims to provide a testing ground for quantum resistance without affecting the Bitcoin mainnet.
Glassnode reports 6.04 million BTC vulnerable to quantum attacks: 1.92M structural risk (Satoshi-era P2PK) and 4.12M operational risk from address reuse. Major exchanges show stark differences: Coinbase 5%, Binance 85%, Bitfinex 100%.
A resident, joined by two Wyoming-based firms, petitioned the New York Supreme Court to declare over 39,000 inactive BTC wallets as abandoned property, seeking title registration. Technical barriers—especially the lack of private keys—make the ruling likely symbolic.
Google Quantum AI's new whitepaper says breaking Bitcoin only needs 1,200 logical qubits—20x lower than prior estimates—with quantum hardware expected by 2033. The real crisis is not physics but Bitcoin's conservative governance, as anti-quantum upgrades would halve throughput and triple fees, with consensus potentially taking a decade.
Google Quantum AI team estimates that a quantum computer with ~500k physical qubits can crack secp256k1 private keys in minutes. Three attack models defined: on-spend, at-rest, on-setup. Bitcoin, Ethereum face structural vulnerabilities. Full circuit withheld via ZK proof.
