### AI overview

The article distinguishes quantum-resistant cryptographic primitives from quantum-safe blockchain systems. It explains why replacing ECDSA alone may not address vulnerabilities elsewhere in a protocol, and discusses post-quantum approaches including lattice-based, hash-based, and code-based cryptography.

### Source excerpt

Quantum-safe blockchain design requires more than replacing ECDSA. This article examines the protocol layers that still matter after post-quantum migration.
