According to CoinMeta, Blockstream released a report evaluating three lattice-based signature schemes: Dilithium, Falcon, and Hawk. The report indicates that Hawk has been withdrawn, Dilithium has a signature and public key size that is too large, while Falcon is considered the best in terms of compactness, verification speed, and maturity. If choosing a lattice-based signature scheme for Bitcoin, there is a greater preference for Falcon-1024.
