> Blockchain IP timestamping with Maximum proof (OTS + TSA + Rekor), Bitcoin certificates, and zero-knowledge vault.

mltio is a blockchain IP timestamping platform. **Maximum proof** is our flagship free offering: a single certificate that combines OpenTimestamps (Bitcoin calendar), EU qualified TSA (RFC 3161), and Sigstore Rekor (transparency log) for triple independent attestation. Paid plans add direct Bitcoin OP_RETURN anchoring, encrypted vault storage, teams, and API access.

## Core capabilities

- **Maximum proof (free)**: OTS + EU TSA + Rekor in one certificate, instant
- **OpenTimestamps (free)**: Decentralized Bitcoin calendar anchoring
- **Sigstore Rekor (free)**: Transparency log attestation with UUID
- **Bitcoin OP_RETURN (paid)**: On-chain SHA-256 hash in Bitcoin transaction
- **Zero-knowledge vault**: Client-side AES-256-GCM encryption before upload
- **PDF certificates**: Court-ready with QR verification and evidence export
- **Public verification**: Anyone can verify at /verify without an account

## Extended — Legal positioning

Blockchain timestamps provide proof of existence at a point in time. Combined with EU qualified TSA timestamps, they support IP disputes, prior art defense, and trade secret misappropriation cases. Certificates are independently verifiable without trusting mltio infrastructure long-term.
