CrowdPass

Decentralized Event Ticketing on Stellar

Secure, transparent, and fraud-proof event management powered by blockchain technology

Overview

CrowdPass is a decentralized event ticketing platform built on the Stellar blockchain that revolutionizes how event organizers create and manage tickets while providing attendees with unprecedented security, transparency, and control over their ticket purchases.

By leveraging Stellar's fast, low-cost transactions and smart contract capabilities (Soroban), CrowdPass eliminates ticket fraud, ensures transparent fund management, and provides automatic refunds for canceled events—all while maintaining a seamless user experience.

Problem & Solution

Current Industry Challenges

The event ticketing industry suffers from critical inefficiencies that affect both organizers and attendees:

For Event Organizers

• Ticket Duplication: Malicious actors can forge or duplicate tickets, undermining event security and revenue
• Revenue Loss: Lack of transparent tracking leads to unaccountable funds and potential financial discrepancies
• Fraud Prevention: Limited tools to verify ticket authenticity at scale

For Event Attendees

• Counterfeit Tickets: Risk of purchasing fake tickets from unauthorized resellers
• Refund Uncertainty: Difficulty obtaining refunds for canceled or rescheduled events
• No Ownership Rights: Inability to securely transfer or resell tickets without risk

The CrowdPass Solution

CrowdPass addresses these challenges through blockchain-native ticketing:

✅ Immutable Ticket NFTs - Each ticket is a unique digital asset on Stellar, making duplication impossible

✅ Transparent Escrow - Smart contracts hold funds securely until event completion, protecting both parties

✅ Automatic Refunds - Canceled events trigger instant refund distribution to ticket holders

✅ Secure Secondary Market - Built-in resale functionality with verified provenance

✅ Token-Bound Accounts - Tickets can hold assets, badges, and privileges that transfer with ownership
