Coinbase urges Bitcoin quantum preparation – ‘Begin this work now’

Coinbase is urging Bitcoin developers and ecosystem participants to begin preparing for potential quantum-computing threats now, rather than waiting for the technology to mature. The concern is that sufficiently powerful quantum computers could undermine the cryptographic signatures protecting Bitcoin funds, though no immediate threat is indicated. The key implication is that Bitcoin may need a coordinated, long-term transition to quantum-resistant cryptography, with planning and testing starting well in advance.
