Coinbase lays out flexible designs as key priority for Bitcoin’s post-quantum migration

Coinbase argues that Bitcoin’s post-quantum migration should prioritize flexible designs that can adapt as quantum threats and cryptographic standards evolve. The challenge is to enable future upgrades without disrupting Bitcoin’s existing security model or forcing premature adoption of a specific solution. The implication is that preparation should begin well before quantum computers pose a practical threat, since coordinating and deploying protocol changes could take years.
