Seoul Labs has launched LetsTicket, a mobile platform that records ticket history on a blockchain and uses rotating QR codes to curb scalping and fraud.

Blockchain company Seoul Labs has officially launched LetsTicket, a mobile ticketing platform that uses distributed ledger technology to prevent forged tickets and illicit trading. Tickets are issued only to accounts that have completed identity verification, and every issuance is recorded on a blockchain network. The design targets illegal macro-based booking and scalping, long-standing problems in both physical and electronic ticket markets.

Dynamic QR and gift-only transfers

Security relies on a dual-encryption structure. The entry QR code refreshes automatically at set intervals, which the company says blocks duplicate entry through screenshots or copied images. Transfers are limited to an official in-app "gift" function, closing off resale at a premium through second-hand marketplaces or social media.

First project: a media art exhibition

The platform goes beyond booking and entry checks. Its first official deployment is the media art exhibition "Let's Bible Season 3: The Salvation," which tells the biblical story of salvation across seven themed halls, from Hall 1 "GENESIS" to Hall 7 "GLORIA." The show combines cyclorama, museum theater and interactive installations. LetsTicket supplies pre-booking, session management and dynamic QR entry for the exhibition.

Inside the venue, visitors can complete QR missions in the app and earn rewards. Quests tied to the visitor route earn points, and the app supports cash top-ups and on-site payments. Ahead of the opening, Seoul Labs is recruiting official supporters; those selected after identity verification receive promotions including a 10,000 won discount coupon for their first ticket purchase.

What comes next

Seoul Labs plans to use the exhibition as a reference case and expand LetsTicket to large concerts, festivals and sporting events, where the risk of illegal ticket trading is high. The company aims to build what it calls a transparent and safe smart-ticketing ecosystem by pairing blockchain tamper resistance with audience-participation tools.
