🎟️ TICKET VALIDATOR CLI (RUST)

---

This cli tool allows creation and validation of ticket for events.

A Rust command-line application for creating, validating, and burning event tickets.
This project reflects my current stage in learning Rust and is the first step in my journey toward blockchain development.

The setup is done using cargo, you can also use the exe from the release , you'll need to install rust if it's not available

Features

• Create tickets with unique UUIDs
• generation of SigningKey deterministically
• Sign and verify tickets using master_seed(32 bytes) -> Hdkf -> seed(32 bytes) -> ed25519-dalek -> key/pair
• Validate tickets once and burn them after scanning
• Store tickets with pickledb
• Simple CLI commands: create, scan, help

Tech Stack

• Language: Rust
• Libraries:
  • uuid for ticket IDs
  • hdkf / sha2 for generating seed from master_seed
  • ed25519-dalek for signing
  • pickledb for storage
  • clap for CLI parsing

Sample Commands Usage

Ensure to create a .env file with key MASTER_SEED containing your 32 byte seed Example

MASTER_KEY="[125,213,213,143,89,111]"

# Create a new ticket
cargo run -- create "<Event_Name>" <Price>

#Scan a ticket/ Use a ticket
cargo run -- scan <ticket_uuid>

Example Usage

# Create a new ticket
cargo run -- create "Test Event" 500.00

# Scan a ticket
cargo run -- scan 886e447c-1adf-4d9e-84e5-92348344f759
