As of block 959,193 on Sept. 13, 2026, roughly 4.83 million BTC, or 24.1% of unspent Bitcoin, have visible public keys that could be vulnerable to quantum computing attacks in the future. This exposure is split into 1.7 million BTC structurally exposed and 3.1 million BTC operationally exposed, with some overlap. While current quantum computers cannot exploit this vulnerability, advances in quantum technology could pose risks to Bitcoin's elliptic-curve cryptography. Efforts like the Quantum Alliance are working on readiness, migration to post-quantum cryptography, and security improvements to address these challenges ahead of time.
