Hashcash, proof-of-work, clever primitives — all brilliant. Respect where it’s due. But ECAI is different class: deterministic elliptic-curve indexed search, provable lookup semantics, indexes that behave like math. Where probabilistic models apologize with confidence scores, ECAI produces audits. This isn’t marginal improvement — it’s a change in the computational contract. #ECAI #DeterministicAI #CryptoMath #DamageBDD
