# Algorand (ALGO) Quantum Readiness Report

> Algorand has a QRI score of 46.5/100 and is assessed at Stage 3 (Migration Live) with medium evidence confidence.

Evaluation date: 2026-08-17. Review status: draft. Evaluated scope: Algorand mainnet native asset (ALGO) and base protocol layers.

Algorand is in an active transition phase (Stage 3: Migration Live). State proofs have been secured with Falcon-1024 signatures since 2022, and a native Falcon-1024 account upgrade (v5.0.0) has passed consensus and is in cooldown for mainnet activation. However, as of the evaluation date, default spend authorization remains entirely Ed25519-based, and the consensus layer (VRF and validator signatures) is completely classical. All circulating value is held in quantum-vulnerable accounts, and no independent cryptographic audit of the PQ implementation is documented. These gaps result in multiple material caps that limit the final QRI stage and score.
