EventLedger: Programmable Access Infrastructure
Treating event tickets as evolving, programmable access rights with decentralized media storage and secondary resale rules.
Built with Karan Singh Bisht.
Overview & Research Motivation
EventLedger treats a ticket not as a static, easily forged QR code, but as a dynamic, cryptographic access right that evolves across its lifecycle. The system models verifiable ticket issuance, controlled secondary resale price caps, anti-scalping policies, and programmable royalty distributions.
Built on Sui Move for object-centric access control and integrating the Walrus decentralized storage protocol with Seal encryption, EventLedger advanced to the Walrus Foundation RFP technical-review process for decentralized event infrastructure.
The Core Systems Problem
- Traditional event ticketing suffers from counterfeit screenshots, predatory bot scalping, and complete lack of artist royalty enforcement on secondary resale markets.
My Specific Technical Contributions
- Wrote Sui Move smart contracts utilizing object capabilities for dynamic ticket state transitions.
- Integrated Walrus protocol decentralized storage and Seal encryption for gated event media and QR generation.
- Authored the comprehensive technical architecture specification submitted to the Walrus Foundation RFP.
System Architecture & Verification Pipeline
Sui Move Object Model
Tickets modeled as dynamic on-chain objects with embedded transfer policies, expiry hooks, and price caps.
Walrus & Seal Encrypted Media
Decentralized storage of ticket metadata and dynamic rotating access tokens decrypted only upon gate check-in.
Programmable Secondary Market
Enforces non-bypassable organizer royalties and maximum resale markup ceilings directly at the protocol level.
