Trust Stack

Verification technology that travels across products

The core asset is not a single screen. It is an evidence format and verifier that external auditors can inspect independently.

Receipt / Proof

Bind API calls, output hashes, usage, and timestamps into one evidence unit.

Hash Chain

Preserve ordering and make after-the-fact mutation visible.

Verifier

Enable exported evidence to be checked without blindly trusting the service database.

Audit Export

Produce evidence bundles customers, auditors, and procurement reviewers can inspect.

Enterprise / Procurement

Procure the AI evidence package for your institution

Available through KONEPS and Venture Nara

The Rantropy AI Action Evidence Package can be purchased through Korean public procurement. We review security, operating requirements, documentation, and schedule before agreeing on deployment scope.

  • Review the institution's goal and expected usage
  • Check account access, network, and data retention requirements
  • Agree on usage records and verification material for review
  • Set the quote, contract, rollout schedule, and support channel
