ZKTPS-V2
A Decentralised Ticketing system on starknet leveraging zk snark on starknet with availability of L1-L2 messaging also
About
The problem it solves High Costs: Traditional ticketing platforms impose substantial fees, including service and processing fees, making it expensive for smaller organizers to host events. Centralization: Existing ticketing systems rely heavily on third-party platforms, leading to single points of failure, biased policies, and data breaches, reducing transparency and control for users. Black Marketing: Tickets often enter a secondary market where they are sold at inflated prices, disadvantaging genuine fans and enabling unfair profits for scalpers. Replay Attacks: Traditional ticketing systems are vulnerable to replay attacks, allowing malicious actors to reuse valid ticket transaction data for unauthorized access, compromising event security. Additional Features Earlier the project was having L1-L2 messaging as a mode for verifying zk snarks proofs as they was unavailable on starknet, now we added zk snarks using garaga( a library to use zk snarks on starknet itself) by this invalidators don't have to carry eth in order to invalidate tickets.
How it's made
Challenges we ran into While implementing garaga , as it is new in the community we faces several syntax issues due to improper and outdated docs and version problems.
