Blockchain Chains Quantum Risk Index

Risk: varies · Confidence: high · Reviewed: 2026-07-19

Verdict

Every listed chain uses classical public-key cryptography on important authorization paths unless a page explicitly documents enforced PQC. Use per-chain hubs—not a single score.

Overview

This index lists chain and L2 cryptography dossiers published by the finance page factory. Market rankings change; our pages track mechanisms (signatures, validators, bridges), not price.

Start with Bitcoin, Ethereum, Solana, and Polygon if you are new, then open other L1/L2 profiles from Waves 6–7. Full chain list is also in the XML finance sitemap (split into chunks after Wave 7j).

For tokens and DeFi apps see /crypto and /is-quantum-proof/defi. For a full hub map see /is-quantum-proof/wave7-hub-map. Enterprise cores: /industries/finance and /industries.

What breaks

Assuming all L1s share identical quantum exposure
Ignoring L2/bridge operator keys

Mitigations

Open each chain hub for signature and key-exposure notes
Map bridges separately
Run organizational assessment for non-chain controls

FAQ

Is every chain quantum-proof?

No. See each dossier’s verdict; most are classical-signature systems today.

Where are assets?

Asset dossiers live under /crypto/{slug}; many chains also have /crypto/{native}.
