### 🧵1️⃣ What is SPEX, and why does it matter? AI is powerful, but it’s also **non-deterministic** — meaning you can’t always reproduce its results. That’s a big problem when trying to **trust AI** in smart contracts. 💡 Enter **SPEX**: Statistical Proof of Execution. It’s @wardenprotocol ’s cryptographic “firewall” for AI. ---

2️⃣ **The Problem with AI in Web3** 🧠 AI models (like LLMs) generate outputs that vary with each run ⛓️ Blockchain requires **deterministic execution** for consensus 😬 Most infra can’t verify if an AI did the right thing So how do we **trust** AI outputs? ---

3️⃣ **SPEX: A New Kind of Proof** SPEX doesn’t aim to replicate AI behavior deterministically. Instead, it uses **statistical sampling** and **cryptographic proofs** to verify: ✅ The model that was used ✅ The inputs it received ✅ The statistical confidence in the output ---

4️⃣ How it works in 3 steps: 🔍 1. A verifier samples model executions 🧮 2. SPEX compares predicted vs actual outcomes 🔐 3. The result is encoded in a cryptographic proof It’s like peer-review for AI — but on-chain, scalable, and automated. ---
