Nine Blockchain Groups Unite as Quantum Threat Hangs Over Bitcoin

Nine blockchain organizations launched the Quantum Alliance this week to set common security standards before quantum computers can crack the digital signatures protecting crypto wallets. The coalition cites roughly 6.4 million BTC at potential risk, including an estimated 1.1 million BTC tied to Satoshi Nakamoto. The threat is long-dated and no exploit is imminent, so the story is more of an industry-coordination signal than a near-term price catalyst for traders.
