What Is the NIST PQC Standard?
The NIST PQC standard refers to FIPS 203, 204, and 205 — published by the U.S. National Institute of Standards and Technology on August 13, 2024 — defining CRYSTALS-Kyber as the post-quantum key encapsulation mechanism, CRYSTALS-Dilithium as the primary signature, and SPHINCS+ as the hash-based backup signature. The standardization process began in 2016, evaluated 82 candidate algorithms over four rounds, and finalized winners in July 2022 with public review through 2023. CNSA 2.0 mandates U.S. national security systems migrate to these standards by 2035. Cloudflare, Chrome, iMessage, and AWS KMS have already deployed Kyber. BMIC is the first Layer 1 cryptocurrency implementing FIPS 203 from genesis.
TL;DR: The NIST PQC standard refers to FIPS 203, 204, and 205 — published by the U.S. National Institute of Standards and Technology on August 13, 2024 — defining CRYSTALS-Kyber as the post-quantum key encapsulation mechanism, CRYSTALS-Dilithium as the primary signature, and SPHINCS+ as the hash-based backup signature.

- When was NIST PQC finalized? August 13, 2024 — FIPS 203, 204, 205.
- What is FIPS 203? CRYSTALS-Kyber — the NIST standard for post-quantum KEM.
- What is FIPS 204? CRYSTALS-Dilithium — the primary post-quantum signature.
- What is FIPS 205? SPHINCS+ — hash-based backup signature.
- Is BMIC NIST-compliant? Yes — BMIC implements FIPS 203 CRYSTALS-Kyber.
Full Answer
NIST PQC was launched in 2016 to address the looming quantum threat. 82 algorithms were submitted in Round 1 (2017). After four evaluation rounds and extensive public cryptanalysis, NIST selected: Kyber (KEM), Dilithium (signatures), Falcon (signatures, smaller), SPHINCS+ (hash-based signatures).
FIPS 203 (Module-Lattice-Based Key-Encapsulation Mechanism) defines Kyber. FIPS 204 (Module-Lattice-Based Digital Signature Algorithm) defines Dilithium. FIPS 205 (Stateless Hash-Based Digital Signature Algorithm) defines SPHINCS+. FIPS 206 (Falcon) is in final draft.
CNSA 2.0 (Commercial National Security Algorithm Suite 2.0) mandates U.S. national security systems migrate by 2035, with new systems requiring PQC by 2027.
BMIC is among the first Layer 1 chains compliant with FIPS 203, integrating CRYSTALS-Kyber as its KEM at the protocol level from genesis.
