# TicketBox - a Proof of Participation (PoP) NFT dispenser built on top of zk-compression.

## Problem
- Storing data on-chain, such as for NFT dispensers or airdrops, is costly on Solana using traditional accounts.

- High storage costs hinder scalability and accessibility, especially for applications needing extensive state management (e.g., event participation tracking).

## Solution

TicketBox - A Cost-Efficient PoP NFT Dispenser
- TicketBox uses ZK Compression on Solana to deliver a scalable, cost-effective Proof of Participation (PoP) system for NFTs.
- Compresses on-chain state to slash storage costs while preserving Solana L1’s security and performance.


## TicketBox includes:

- TicketBox Protocol:
    - A zk-NFT standard inspired by the Metaplex Core standard.
    - TicketBox: A zk-NFT dispenser protocol. Think of it like the Metaplex Candy Machine, but for zk-NFTs.
- TicketBox Platform:
Built on top of the TicketBox Protocol, this no-code tool allows event creators to easily create events and distribute zk-NFTs to users. Attendees can easily collect a Proof of Participation NFT by scanning a QR code.
