Which of your wallets, bridges, or governance keys would fail first if a quantum computer showed up tomorrow? Every exposed public key onchain is a future liability. A quantum computer could recover the private key behind it and forge authorizations.

NIST's 2024 standards (ML-KEM, ML-DSA, SLH-DSA) point the way, but none are drop-in fixes onchain. Bigger signatures, heavier verification, real gas costs. Read more ↓ openzeppelin.com/news/why-po…

From Algebra to Noise: Why Post-Quantum Cryptography Looks Different

A guide to exposed public keys, the cryptography behind the risk, and the migration ahead: wallets, custody, bridges, governance, validators, and smart contracts before Q-Day.

A useful next step would be a benchmark table for onchain signature verification: signature size, verification gas, target chain and implementation assumptions. That would make the deployment trade-offs much easier for project researchers to compare.
