NIST finalized its first three post-quantum cryptography standards in August 2024 and told organizations to begin migrating immediately, with a 2035 deadline to deprecate quantum-vulnerable public-key algorithms from its guidelines. Coinbase's advisory board reached the same conclusion in a recent report, arguing that blockchains, wallet providers, exchanges, and custodians should prepare before urgency arrives, and that unresolved public decisions around migration are already deterring some investment. Google set an internal PQC migration timeline for 2029 in March and updated its threat model to prioritize authentication services.

Apr 1, 2026 · Gino Matos Those three directives share a structure that treats readiness as the operative matter. That convergence turns post-quantum planning from a debate in cryptography into a test of governance and credibility. Crypto wallet threat illustration The full-stack migration problem Coinbase's paper maps the migration burden across a stack consisting of consensus layers, execution layers, wallets, exchanges, custodians, key management systems, and hardware. It warns that hardware-based wallets and hardware security modules take time to update, that MPC support may differ by algorithm, and that many major blockchains have not committed to exact post-quantum signature choices. NIST defines crypto-agility as the ability to replace and adapt algorithms across protocols, applications, hardware, firmware, and infrastructure while preserving operations. Against that definition, crypto infrastructure providers are left to assess if their full stack can absorb an algorithmic transition without operational disruption. For most, the answer is still unresolved. A readiness matrix maps post-quantum migration requirements
