ARKIV IDEATHON · CONCEPT DEMONSTRATION
Attendance should outlive the platform.
An interoperable attendance passport built on Arkiv. Organizers issue verifiable claims, attendees control them, and any compatible app can query them — no central database required.
Concept demonstration — not a live credential registry.THE PROBLEM
Event history should not disappear with a platform.
Attendees lose access to their participation history.
Isolated platform × portable proof
Organizers cannot easily verify credentials from other platforms.
Isolated platform × portable proof
Sponsors and partners cannot query trusted attendance without contacting every issuer.

INTERACTIVE ARKIV DATA MODEL
The data model is the product.
Expand an entity to see what it carries, who controls it, and how long it lasts.

Public, canonical metadata that every compatible application can resolve.

PRIVACY BOUNDARY
Public verification does not require public personal data.
Stored on Arkiv
✓ Public event metadata
✓ Pseudonymous identifiers
✓ Signed claims
✓ Proof hashes
✓ Issuer and ownership metadata
✓ Expiry and status fields
Kept privately by HashPass
✓ Names
✓ Emails
✓ Phone numbers
✓ Raw QR codes
✓ Anti-replay secrets
✓ Device and location details
✓ Fraud scores
✓ Private networking data
✓ Organizer notes
THE COUNTERFACTUAL
Why not a plain database?
Queryable
Attendance records are indexed and filterable.
Time-scoped
Evidence expires by design.
Tamper-proof provenance
$creator makes the issuer independently verifiable.
Wallet-controlled ownership
$owner lets the attendee control the credential.
Without Arkiv, OpenProof is just another private database or closed collectible platform. With Arkiv, any compatible app verifies the same public credential layer — no dependency on HashPass’s private API.
AN OPEN STANDARD, NOT AN NFT COLLECTION
Build an open attendance layer.
Starting with event infrastructure in Chile and Colombia — built for any compatible event platform.
Designed for the Arkiv Ideathon — concept demonstration.
