Domain Drop Catching Game - .TSH Registry

A hobby project implementing a domain registry system for practicing drop catching techniques. Built with Bun and zero dependencies.

Live instance: https://nic.bullshit.video

Overview

Drop catching is the practice of registering domain names the moment they expire. This project provides a playground for developing and testing drop catching algorithms with:

• Random domain releases during a 42-minute window
• Score-based domain values (1-100)
• Rate limiting with progressive penalties
• Real-time competition between registrars

Features

• EPP Server (Port 700) for domain registration
• WHOIS Server (Port 43) for domain information
• Built-in rate limiting with penalties
• Domain value scoring system (1-100)
• Automatic domain expiry and replenishment

System Components

Domain Expiry (Cron)

• Runs daily at 15:00 (France/Paris)
• 42-minute release window
• Random release timing for each domain
• Minimum 42 domains per session

Rate Limiting

• 5000 requests/hour
• 500 requests/minute (~8 requests/second)
• Penalties after 5 violations:
  • 1-second delay added to requests
  • 2 tokens deducted from balance

Domain Scoring

• Rare (90-100): 5% chance
• Valuable (70-89): 15% chance
• Average (30-69): 60% chance
• Low (1-29): 20% chance

Usage Examples

WHOIS Queries

# Domain lookup
whois -h whois.nic.bullshit.video example.tsh

# Registrar lookup
whois -h whois.nic.bullshit.video "registrar test1"

# Help
whois -h whois.nic.bullshit.video help
