Coinbase is urging bitcoin developers and industry stakeholders to begin preparation for a post-quantum transition sooner rather than waiting for a hypothetical “Q-Day,” when quantum computers could threaten current cryptography. In separate technical reporting and a public post, Coinbase argues that the migration process could take years and therefore needs to start now.
Across outlets, Coinbase’s focus centers on practical implementation details. It highlights the need for “flexible” designs such as adaptable address handling, signature upgrades, and safer custody approaches. Coinbase also discusses how to manage funds held across different states, including dormant coins and the problem of lost coins, which could complicate the migration timeline. The exchange frames its proposals as requirements that must be addressed in advance, including planning for block-space and key management so bitcoin can transition to quantum-resistant mechanisms without disruption.
