OnlyPass: Human-verified ticketing platform leveraging proof of personhood and blockchain-backed tickets.
OnlyPass aims to revolutionize event ticketing by building a next-generation ticket selling app. Each ticket is minted as an NFT (non-fungible token), and every buyer is verified as a real human using cutting-edge Worldcoin iris-scanning technology. This approach solves the persistent problems of bots, scalpers, and ticket fraud—ushering in a new era of fair, secure, and transparent ticket sales.
Bots buy up tickets in seconds, reselling them at inflated prices—sometimes up to 50% higher than face value.
In major events, bots have bought tens of thousands of tickets before real fans can even click “Buy”.
Scalping is so lucrative that bots now generate up to 40% of all ticketing traffic.
CAPTCHAs, once the main defense, are now easily bypassed by sophisticated bots.
Studies and industry reports confirm that “the possibility to reliably tell a bot from a human through something simple like a CAPTCHA is a thing of the past in an industry like ticketing”.
CAPTCHAs frustrate real users, sometimes even preventing legitimate purchases due to technical glitches or accessibility issues.
Lack of control over ticket transfer leads to price gouging, fraud, and a poor fan experience.
Existing anti-scalping laws are poorly enforced, and primary ticket sellers rarely take responsibility for how tickets are distributed.
Our platform combines advanced blockchain and biometric technologies to deliver secure, human-verified NFT ticketing:
-
🧍 Human Verification: We use Worldcoin’s Orb device to perform secure iris scans, generating a unique, privacy-preserving digital identity for each user. No biometric data is stored—only a cryptographic proof that ensures each participant is a real, unique person.
-
🎫 NFT Ticketing: Tickets are minted as NFTs on the blockchain, guaranteeing authenticity, transparency, and programmable ownership. This enables features like resale restrictions and royalty enforcement.

You can interact with our factories (addresses bellow) and call function creatNFT(...) or you can deploy your own and start creating new tickets using scripts in repo.
