Consensus: No Signatures / Quantum Resistant
Why this rating. Proof-of-work mining with Etchash (ECIP-1099), so block production uses no digital signatures.
Transactions: Quantum-Vulnerable
Why this rating. Accounts use secp256k1 ECDSA. An ML-DSA-65 precompile draft (ECIPs PR 557, core-geth PR 5) is open and unmerged, from an outside contributor. Maintainers say the client is in maintenance mode.
Algorithms: None listed

Source: Source
Note and links: PoW consensus has no signatures
