# 🟣 Crovia — CEP Capsules (v1)
**Crypto Evidence Packages for the AI Act Era**  
Portable, offline-verifiable provenance capsules for the world’s most-used open datasets.

> **If a dataset shaped modern AI, it deserves a receipt.**  
> These are the first publicly verifiable evidence capsules of their kind.

# 🚀 What Are CEP Capsules?
A **CEP.v1 capsule** (*Crypto Evidence Package*) is a compact, self-contained file that proves:

- **where attribution signals came from**  
- **how payouts would be computed**  
- **which trust bundle verified the run**  
- **what the hashchain root is**  
- **that everything inside is immutable**

Each capsule is:

- **📦 portable** (just a JSON file)  
- **🔍 independently verifiable** (3 lines of Python)  
- **🛡 AI Act–aligned** (trust bundle, receipts, payouts)  
- **⛓ backed by a hashchain** (tamper-evident)  

Think of this not as a dataset —  
**but as the evidence layer underneath datasets.**

# 🧪 Verify Any Capsule in 3 Lines

Save a capsule (e.g. `CEP-C4-2025-12.json`) locally and run:

    import json, hashlib

    with open("CEP-C4-2025-12.json") as f:
        cep = json.load(f)

    root = cep["hashchain"]["root"]
    print("Root:", root)
    print("Valid:", root == hashlib.sha256(cep["payouts"].encode()).hexdigest())

Everything is verifiable **offline**, with **no token**, **no API**, **no Crovia server**.

# 🧠 Why This Matters
Modern AI models are trained on massive public datasets…  
…but nobody can **prove**:

- what signals came from where  
- how much each source contributed  
- how payouts would flow  
- what trust criteria were applied  
- whether logs were tampered with  

**Crovia introduces the evidence layer that the ecosystem was missing.**  
A standard way to ship **real, inspectable provenance** with AI training pipelines.

These capsules:

- help researchers audit models  
- help companies comply with the AI Act  
- help dataset creators receive attribution visibility  
- help the community trust what models are built on
