Verified Ticketing & Collectibles for a Live-Events Group
A live-events group was losing gate integrity to screenshot resale: the same ticket arriving three times, arguments at the door, refunds after the fact. We rebuilt their ticketing on verifiable rails — each ticket issued on a low-fee blockchain at purchase, presented as a rotating QR that a screenshot can't steal, scanned by a gate app that settles validity in milliseconds — with post-show digital collectibles that turned the same rails into a fan perk.
Screens are illustrative recreations — client interfaces stay confidential.
The challenge
Duplicate and doctored tickets averaged 20+ incidents per event, each one a gate delay and often a refund — and the group had no way to distinguish the legitimate buyer from the screenshot.
Any fix had to stay invisible to fans: normal checkout, email-based ticket access, no wallet setup or crypto vocabulary anywhere in the purchase path — and gate scanning had to stay under half a second on venue Wi-Fi.
What we built
Invisible on-chain issuance
Tickets mint on a low-fee EVM chain (Polygon) at purchase against audited contracts, held in managed wallets keyed to the buyer's account — fans see a normal ticket in their email and a wallet-export option they can ignore.
Rotating entry codes
The ticket renders as a time-rotating QR bound to the on-chain asset, so a static screenshot expires in seconds; transfers go through the platform, which reissues codes to the new holder.
A gate app that never queues
Scanner apps verify signatures locally against a pre-synced event state and settle on-chain checks asynchronously — median scan 320 ms, functional even when venue connectivity dips.
Collectibles as the encore
After each show, attendees can claim a free commemorative collectible tied to their ticket — artwork per event, claimed in one tap, tradable for the fans who care and ignorable for everyone else.
The results
- 38k
- Tickets issued on-chain
- 320 ms
- Median gate scan
- 0
- Duplicate-entry incidents
across 30+ shows in one season
local verification with async settlement
from show 3 onward, vs. 20+ per event prior
- 38,000 tickets issued on-chain across the season with checkout conversion unchanged — fans never noticed the rails.
- Duplicate-entry incidents fell from 20+ per event to zero within the first three shows and stayed there.
- Roughly a third of attendees claimed post-show collectibles, giving the group a direct-engagement channel it had never had.
Client identities stay confidential; figures are rounded from end-of-engagement delivery reporting.
