Consensus
Post-Quantum

Why this rating. Blocks, checkpoints and attestations are verified with pre-standard Dilithium3 (CIRCL mode3) in the consensus code, with no classical path. Mainnet chain 1668 answered RPC with a current block on 2026-10-23.

Transactions
Post-Quantum

Why this rating. Native transactions are verified with pre-standard Dilithium3 (CIRCL mode3); ML-DSA-65 appears only in threshold-wallet code. The whitepaper says secp256k1 is disabled by default. Mainnet has run since September 2026.
