Coinbase is urging the Bitcoin ecosystem to begin planning for a transition to quantum-resistant cryptography, despite the absence of an immediate threat. The exchange recalls that network upgrades, which require years of development and broad consensus among nodes, miners and wallet providers, cannot be deployed overnight. The BIP-360 proposal is among the technical solutions currently under review to adapt Bitcoin’s output structure. Coinbase emphasizes that dormant older coins, whose owners are inactive, represent a particular challenge in the event of a future migration. The exchange’s argument rests on anticipation rather than alarmism: if years are needed to reach agreement on major changes, preparatory work must begin long before a sufficiently powerful quantum computer becomes a reality.
