Consensus: Post-Quantum Ready
Why this rating. Judgment call: the project's own XDPoSChain repository has a poc_falcon branch that signs and verifies block headers, votes, quorum certificates and timeouts with Falcon. It is unmerged, last changed August 2025, and not deployed.
Transactions: Quantum-Aware
Why this rating. The poc_falcon branch does not touch transaction signing. A 2026 initiative proposes hybrid ECDSA plus ML-DSA wallets from 2027 and EVM precompiles later. These are proposals with no published transaction code. Accounts use secp256k1 today.
Algorithms: FN-DSA (Falcon)

Note and links: Falcon proof of concept only
