Pact
Provable agreements for any deal.
Notarized contracts to inter-org deal sealing — every signature, witness, and version cryptographically tied to identity.
Trust shouldn't require a middleman. It should come from math.
VerifyLink Infrastructure is the cryptographic layer that makes it possible for any system to seal what happened, register it immutably, and prove it to anyone — without asking them to take your word for it.
DIAGRAM SLOTvli-stack.svgThe VLI stack: protocol → registry → tools → applications
The same shift that brought formally verified cryptography to your TLS connections — we're bringing to the evidence layer. Every attestation, every audit artifact, every agreement. Sealed by math. Verifiable forever.
Seal
Cryptographically lock any event, document, or decision so it can never change without leaving a trace.
Ed25519 + JCS + SHA-256 Learn more → Register
Anchor your seal in a public, append-only Merkle log. Proves when, in a way no one can quietly alter.
Merkle log + inclusion proof Learn more → Verify
Confirm any seal, anywhere, with no account. ClearKey checks signatures, JCS, and registry inclusion offline.

Preserve sealed bundles long-term and produce audit-ready exports on demand for any framework.

Five products running in production today. Every event sealed, every receipt verifiable.
WorkSpaces
Compliance as a side effect of running your org.
Sealed inventory, attested check-ins, immutable audit trail, AI registry — the org OS where every action becomes evidence.
TapIn
Verified arrivals, signed in real time.
Patients, attendees, members — biometric tap-in produces a sealed receipt, no shared databases, no spoofable badges.
Origin
Cryptographic proof of authorship.
Drop a file, get a sealed timestamped receipt anchored to the VLI registry. IP priority and creative attribution that holds up in court.
ART
The public registry of AI agents.
Discover, attest, and verify AI agents and their delegated capabilities — VLI's transparency layer for AI accountability.
Every AI decision your team makes can be sealed and proven later. VLI is the AI accountability layer. Explore AI governance with VLI →
"VLI is always on — a living sealed record of organizational behavior. Compliance isn't something you do. It's something you already have."
- No audit prep — the evidence already exists
- No vendor lock-in — math doesn't expire
- No middleman — verifiable by anyone with ClearKey
