What is Post-Quantum Cryptography?

Most cryptocurrencies today rely on ECDSA (Elliptic Curve Digital Signature Algorithm) or similar cryptographic algorithms to secure transactions and wallets. These algorithms could potentially be broken by sufficiently powerful quantum computers using Shor's algorithm.

Post-quantum cryptography (PQC) refers to cryptographic algorithms that are believed to be secure against both classical and quantum computer attacks. These include lattice-based, hash-based, code-based, and multivariate polynomial cryptography.

This tracker monitors how much of the total cryptocurrency market cap has migrated to quantum-resistant cryptographic solutions. As quantum computing advances, this migration will become increasingly critical for the security of digital assets.

Methodology

The percentage shown is calculated by dividing the combined market cap of chains with native post-quantum cryptography by the total cryptocurrency market cap, using data from CoinGecko.

Important limitations:

  • This metric uses total chain market cap and does not account for individual address types within each chain
  • Addresses that have been reused or have exposed public keys may be more vulnerable, even on PQ-secure chains
  • Some chains listed may have PQ features that are optional or not yet fully deployed
  • Wrapped tokens, bridges, and layer 2 solutions may have different security properties than their base chains

This tracker is intended as a high-level indicator of industry migration toward post-quantum security, not as a definitive security assessment.
