### 🧵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.

---

5️⃣ Why it’s revolutionary:

⚡️ Up to **1000x faster** and cheaper than ZKML
🔗 Doesn’t require TEE (trusted hardware)
🧠 Compatible with non-deterministic AI (LLMs, diffusion models…)
💬 Confidence levels included in the proof

7️⃣ Real-world example: Warden’s AdvancedOrder

Thanks to SPEX, Warden can deploy **onchain orders based on AI predictions** — with the model, input, and execution **all verifiable**.

8️⃣ In short, SPEX is:

🔐 A trust layer for AI
📈 A key to scalable AI/Blockchain apps
🧱 A core component of **Warden’s fullstack architecture**

It’s not just proof of execution — it’s **proof that your AI can be trusted**.
