# Qubic (QUBIC) Quantum Readiness Report

> Qubic has a QRI score of 5.97/100 and is assessed at Stage 1 (Quantum Risk Assessed) with medium evidence confidence.

Evaluation date: 2026-06-01. Review status: draft. Evaluated scope: Qubic L1 native asset (QUBIC) and core protocol.

Qubic is a high-performance, feeless Layer-1 blockchain with a live mainnet processing over 200M transactions per epoch at sub-second finality. Its entire cryptographic stack—spend authorization, consensus authentication, account identity, and wallet paths—relies exclusively on classical ECC (FourQ elliptic curve with SchnorrQ signatures). The project has publicly documented this ECC dependency and has acknowledged the quantum threat in its technical whitepaper and official documentation, briefly mentioning exploratory interest in NTRU and XMSS. However, no PQC design, prototype, testnet, code, migration mechanism, or hybrid protection exists in any critical layer. The network currently has approximately $75-85M in market capitalization, all of which is quantum-vulnerable. CertiK has conducted a performance evaluation (15.52M TPS) but no cryptographic security audit. Qubic receives a QRI Score of 6, placing it firmly in Stage 1 (Quantum Risk Assessed). The score reflects credit for public cryptographic documentation, open-source code, and acknowledged awareness of quantum risk, offset by the complete absence of production PQC protection, migration planning, or concrete mitigation design.
