Provenance in four steps

From raw AI output to cryptographically sealed, independently verifiable record — in under a second.

01 📤

Submit content

Send any AI-generated text, image hash, or code to the API with model name and metadata attached.

02 🔑

Hash & sign

Helios computes a SHA-256 hash and signs it with Ed25519. The private key never leaves the node.

03 🌳

Merkle inclusion

The signed hash is inserted into the append-only Merkle tree. Tampering with any historical entry breaks the root.

04

Verify anywhere

Anyone can verify using the public key and Merkle proof — no trust in Helios required. Pure cryptographic truth.

Everything you need for AI trust infrastructure

A minimal, composable toolkit — nothing more, nothing less.

REST API

Submit, verify, and audit provenance records from any language or platform. JSON in, JSON out.

POST /api/records
🔑

Ed25519 signatures

64-byte signatures, sub-millisecond verification. Modern elliptic-curve cryptography — fast and battle-tested.

🌳

Merkle attestations

Append-only Merkle structure. Historical records are mathematically immutable — silent tampering is impossible.

Reward system

Incentivize contributors who submit provenance records. Configurable reward logic with per-account balances.

🤝

Multi-node consensus

Deploy a network of Helios nodes. Each node broadcasts records to peers with Ed25519 signature verification — federated trust without a single point of failure.

Common questions

What is AI provenance?

The ability to cryptographically prove the origin, creation context, and post-creation integrity of AI-generated content. Helios records a tamper-proof signed entry for each piece of content, creating an immutable audit trail.

How does verification work?

Helios hashes your content and signs the hash with Ed25519. The signature and metadata are stored in a Merkle tree. Anyone with the public key can independently verify the record — no need to trust Helios at all.

Is it free and open source?

Yes. MIT-licensed, freely available on GitHub. Self-host on your own infrastructure or use the public instance at ai.oooooooooo.se.

Which AI models are supported?

All of them. Helios is model-agnostic — GPT-4, Claude, Gemini, Llama, Mistral, or any custom model. Only the content hash matters.

Does Helios store the actual content?

No. Only cryptographic hashes and metadata — never the raw content itself. Your data stays with you; Helios only records proof of its existence and integrity.

Can I run my own node?

Yes. Clone the repo, deploy a Cloudflare Worker with D1, and you have your own node in minutes. Add the public node as a peer to join the federated network — records propagate automatically with cryptographic verification.
