# Solana (SOL) Quantum Readiness Report

> Solana has a QRI score of 23.8/100 and is assessed at Stage 2 (Mitigation / Development) with medium evidence confidence.

Evaluation date: 2026-08-13. Review status: draft. Evaluated scope: Native asset (SOL) and base-layer protocol.

Solana scores 24/100 (Stage 2: Mitigation / Development). The project has published one of the most comprehensive quantum risk assessments in the blockchain industry, with detailed cryptographic inventories, formal migration roadmaps, and prototype Falcon implementations from both Anza and Firedancer. The SHA-512 Ed25519 seed derivation provides a credible theoretical migration path via ZK proofs. However, none of this changes the production reality: all native transaction signatures on mainnet use Ed25519 (broken by Shor's algorithm), TowerBFT consensus uses Ed25519 votes, BLS pubkey registration (SIMD-0387) is already live on mainnet for the upcoming Alpenglow consensus which will use BLS12-381 (also quantum-vulnerable). The opt-in Winterwallet (Winternitz Vault) provides application-layer quantum resistance on mainnet but protects negligible value (<300 accounts). SIMD-0461 (Falcon syscall) was closed/paused in June 2026; the team is exploring a Keccak-f1600 syscall approach instead. SIMD-0296 (larger transactions to 4096 bytes) is activating imminently as prerequisite infrastructure. No independent cryptographic audit of any quantum-critical component exists. No protocol-level PQ spend authorization or consensus authentication exists. Solana is well-prepared on paper but has no material production quantum protection today.
