Consensus: Quantum-Vulnerable
Why this rating. Judgment call: proof-of-work blocks, but Avalanche finalizes them, and stakers sign poll responses and identity proofs with Schnorr over secp256k1. Same test as Dash. No post-quantum work found.
Transactions: Quantum-Vulnerable
Why this rating. Coins use ECDSA or Schnorr signatures on secp256k1, as in Bitcoin. No post-quantum scheme or proposal found in the node repository or roadmap.
Algorithms: None listed
Website: Website
Source: Source
Note and links: Avalanche finalization uses signatures
