'It Can Take Years': Coinbase Presses for Bitcoin Quantum Migration to Start Now

Coinbase is urging Bitcoin developers to begin planning a migration to post-quantum cryptography now, arguing that designing, testing, and deploying protocol changes could take years. The concern is that sufficiently powerful quantum computers might eventually compromise today’s public-key cryptography, putting some bitcoin at risk. No immediate threat is established, but the long lead time makes early research and coordination important to Bitcoin’s long-term security.
