# Midnight (NIGHT) Quantum Readiness Report

> Midnight has a QRI score of 10.5/100 and is assessed at Stage 2 (Mitigation / Development) with medium evidence confidence.

Evaluation date: 2026-06-05. Review status: draft. Evaluated scope: Native asset (NIGHT) on Midnight Network mainnet, including consensus, privacy/proof layers, P2P, and Cardano partner-chain dependencies.

Midnight Network (NIGHT) scores 12/100 on the Quantum Readiness Index, placing it in Stage 2 (Mitigation/Development). The production mainnet (launched March 2026, Kūkolu federated phase) relies entirely on quantum-vulnerable elliptic curve cryptography for all critical layers: sr25519 for AURA block authorship, Ed25519 for GRANDPA finality and libp2p, ECDSA for partner-chain consensus, and Halo 2 (PLONK-derived over BLS12-381) for zero-knowledge proofs. All 24B NIGHT tokens are unshielded UTXOs secured by classical sr25519 public keys with no PQ migration mechanism. The project demonstrates credible post-quantum awareness through the Nightstream lattice-based folding scheme (open-source research prototype on GitHub, developed with Google and Linux Foundation researchers) and architectural concepts like pluggable signatures and statistical blinding for HNDL mitigation. However, none of these mitigations are deployed in production. The raw factor score of 12 reflects the complete absence of production quantum protection across all critical layers, with credit only for risk assessment preparedness and research-stage PQ algorithm development. The score is bounded by the 'Active production spend authorization remains entirely ECC/BLS/Schnorr/EdDSA-only' Readiness & Risk Cap of 40.
