‘Wow, it’s a real discovery’: Claude cracks a 25-year NSA number mystery - CoinDesk — Rickler Feed, Oct 17, 2026, 09:25 UTC
🤖 Claude за полчаса разгадал 25-летнюю загадку криптографии — выяснил, откуда взялись загадочные seed для эллиптических кривых NIST, из-за которых годами подозревали возможный бэкдор NSA. Для Bitcoin повода паниковать нет — он использует другую кривую secp256k1. @DeCenter — AGGREGATOR, Oct 17, 2026, 10:05 UTC
