Google Quantum AI Cuts ECDSA Attack to 1,200 Qubits, but the Engineering Gap Is Massive

Google Quantum AI published research showing they've tailored Shor's algorithm to attack Bitcoin's ECDSA with fewer than 1,200 logical qubits. The headlines are alarming, but the physical reality tells a different story. The gap between 96 entangled qubits and 500,000 fault-tolerant ones is an unsolved engineering problem. Bitcoin developers are already building the fix with SHRIMPS and BIP-360, but rushing changes could be more dangerous than the threat itself. Stories covered: • Google Quantum AI drops ECDSA attack paper, targets 2029 for post-quantum readiness • Alex B breaks down why entanglement and coherence constraints make the threat distant • Jonas Nick introduces SHRIMPS, a post-quantum signature scheme for Bitcoin • BIP-360 proposes quantum-resistant output type, already live on testnet • Powell says Fed can "wait and see" on Iran oil shock, calls $39T debt trajectory unsustainable • John Arnold on Ten31 Timestamp: the Fed can't hike, and the math makes it obvious • Median home has tripled since 1980 adjusted for inflation while wages are up 18% • Axios supply chain attack compromises 100M+ weekly downloads • Primal ships no-KYC Lightning wallet • Oil hits 3-year high above $105, Houthis add second maritime pressure point • China factory activity returns to growth at sharpest pace in a year Full written analysis with all links and on-chain data: tftc.io/bitcoin-brief
