🟣 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.
📘 Included Capsules (Dec 2025 Preview)
| Dataset Slice | Capsule |
|---|---|
| C4 | CEP-C4-2025-12.json |
| LAION 5B (sample) | CEP-LAION-2025-12.json |
| Wikipedia | CEP-WIKIPEDIA-2025-12.json |
| Wikitext | CEP-WIKITEXT-2025-12.json |
| FineWeb | CEP-FINEWEB-2025-12.json |
| The Pile | CEP-PILE-2025-12.json |
| ArXiv abstracts | CEP-ARXIV-2025-12.json |
| OpenSubtitles | CEP-OPENSUB-2025-12.json |
| Stack / Code | CEP-STACK-2025-12.json |
| BookCorpus | CEP-BOOKCORPUS-2025-12.json |
These capsules do not contain dataset content.
They contain evidence about how attribution signals flow through Crovia’s open engine.
🧪 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

Crovia is an independent initiative committed to
transparent, evidence-based AI attribution.
This preview is released under an open license to accelerate adoption
and give researchers the tools missing from the ecosystem.
⭐ If you find this useful…
Please star the dataset.
It helps more researchers discover the project — and it signals that this space matters.
