【Bitcoin’s quantum-resistant progress】A peer-reviewed paper by Blockstream Research compares three lattice-based signature schemes—Dilithium, Falcon, and Hawk—and finds Falcon-1024 to be the strongest candidate for Bitcoin’s next-generation signature scheme: its public key and signature total just 3,073 bytes, and it has the fastest verification speed. However, the report also notes that Falcon-1024 is not yet ready for on-chain use: signing requires about 90 KB of memory, it does not support hierarchical deterministic key derivation, and the FN-DSA standard must be finalized first. Blockstream believes the conservative short-term approach remains hash-based signatures, while Falcon is a long-term strategic option. (Source: Crypto Briefing / Blockstream blog, November 7) $BTC
