# Polkadot (DOT) Quantum Readiness Report

> Polkadot has a QRI score of 15/100 and is assessed at Stage 2 (Mitigation / Development) with medium evidence confidence.

Evaluation date: 2026-06-05. Review status: draft. Evaluated scope: Native asset (DOT) on Polkadot Relay Chain mainnet as of 2026-06-05.

Polkadot has produced one of the most detailed and technically credible post-quantum roadmaps among major L1 blockchains, including a 2025 Web3 Foundation roadmap by Jeff Burdges and a 2026 Draft RFC-0000 for hybrid post-quantum accounts selecting NIST-standardized Falcon (FN-DSA) and Dilithium (ML-DSA). However, as of the June 2026 evaluation date, the Polkadot Relay Chain mainnet uses entirely ECC-based cryptography (sr25519, ed25519, ECDSA) for account signatures, consensus authentication, VRF randomness, and P2P transport. Zero mainnet PQ or hybrid-PQ protection exists. All DOT that has ever been transacted has exposed public keys on-chain, creating a material long-exposure quantum-vulnerable value pool. The RFC explicitly states deployment cannot begin until NIST finalizes Falcon key-derivation standards (estimated 2028). No PQ testnet, prototype code in the official Polkadot SDK, or migration tooling has been publicly identified. The project earns credit for its thorough risk assessment, detailed mitigation design, and NIST-aligned algorithm selection, but these are roadmap artifacts that do not materially protect production users. Polkadot is squarely in Stage 2 (Mitigation/Development) with a QRI Score of 15/100.
