01
Research priority
Hash datasets, notebooks, or manuscript drafts locally. Anchor existence on Bitcoin via OpenTimestamps and share a receipt ID with collaborators or journals.
- Prove a file existed before a publication date
- No raw data leaves the browser
- Verifiers re-hash the original file later
Timestamp a file →
02
Patent & invention evidence
Bind invention disclosures, CAD exports, or lab notes to a cryptographic timestamp before filing. The receipt is independently verifiable years later.
- Ed25519 signature binds your browser key
- Bitcoin anchoring via OTS (~1–2 hours)
- Downloadable certificate when confirmed

03
Partner hosted Auth
Run challenge-bound login on OTRUST while partners keep app state. Users see the OTRUST domain; callbacks return with token and state intact.
- Branded hosted step without replacing eID providers
- Trusted issuer-bound credential verified before callback
- Preview your brand while issuer onboarding is pending

Defense & Government
Timestamp logs, evidence, and documents locally for verifiable chain-of-custody. Prove existence and integrity without ever leaving your classified or air-gapped network. Sovereign, zero-knowledge proofs for audit trails, supply-chain provenance, and classified document workflows.
- Zero-knowledge proofs of prior existence — no data leaves your perimeter
- Bitcoin-anchored immutability outside any national CA or single point of failure
- Full self-host / air-gapped deployments for high-security environments
- Support for evidence bundles, Merkle proofs, and long-term verifiability
- Enterprise SLAs, integration support, compliance assistance (e.g. NATO/FMV), and dedicated defense deployments available
