Post-Quantum Signatures: Dilithium, FALCON, and the Coming Cryptographic Migration

NIST has standardized the digital signature schemes that will replace ECDSA and RSA before quantum computers can break them. CRYSTALS-Dilithium and FALCON are not theoretical curiosities. They are the cryptography that every blockchain, certificate authority, and secure system will eventually run on. Here is how they work and what their adoption actually costs.
