Beam

Consensus: Quantum-Vulnerable
Why this rating. Judgment call: Beam is an Avalanche L1 on the Avalanche stack, where validators use BLS keys and TLS signing. No Beam or Avalanche post-quantum work was found; absence rests on search.

Why this rating. Judgment call: Beam is EVM-compatible (chain ID 4337) with secp256k1 accounts. The Beam docs and BuildOnBeam repositories mention no post-quantum work. Absence rests on search.
