🧠 Meet SecuriGotchi: Your Terminal-Based Cybersecurity Pet with a Blockchain Memory

💡 What is SecuriGotchi?

SecuriGotchi is a terminal-based cybersecurity companion that runs on a Raspberry Pi (or any Linux machine). It looks like a retro command-line pet, but behind its pixelated charm lies a powerful system for:

Gamified cybersecurity tasks
Live system monitoring
Packet capture and scanning tools
Memory and XP tracking
And now… blockchain-backed logs and GPG-signed XP memory

It’s like a mix of a Tamagotchi, a SIEM, and a hacker’s dojo logbook.

🔍 What Can It Do?

🛡 Gamified Security Tasks

You can complete real missions—like scanning your network, running nmap, or sniffing packets with tcpdump—and earn XP that gets logged to your gotchi’s memory.

Each successful mission gives you XP and updates the pet’s level and memory chain.

📜 Immutable Blockchain Memory

Every memory event is stored in a tamper-proof JSON chain, just like a blockchain. Each memory block contains:

A timestamp
Action text (e.g., “Completed Nikto scan”)
XP reward
A hash of the previous block
A GPG signature


{
  "index": 5,
  "timestamp": "...",
  "action": "Completed Nikto Scan",
  "xp": 40,
  "prev_hash": "...",
  "hash": "...",
  "signature": "-----BEGIN PGP SIGNATURE-----..."
}

You can validate the entire memory history and signature chain with one command:


python3 -c "from gotchi_chain import validate_chain; print(validate_chain())"

🔌 Modular Plugin System

SecuriGotchi supports drag-and-drop plugins. Want a new mission that runs fail2ban, or a tool that performs GeoIP lookups? Just drop in a plugin folder with a manifest and a run() function.

Built-in plugins include:

nmap scans
metasploit portscans
tcpdump sniffers
whois, traceroute, geoiplookup, and more
Recon tools like SUID checks and environment variable dumps

Each mission plugin can grant XP and log the outcome to the blockchain memory.

🧰 Installation


git clone https://github.com/CptNope/SecuriGotchi.git
cd SecuriGotchi
chmod +x install.sh
./install.sh

You’ll be prompted to set up a GPG key to sign memory blocks.
All logs go to gotchi_chain.json, with a matching .sig file.

🤖 Why This Matters

Security tools are often reactive, abstract, or overwhelming. SecuriGotchi is:

Personal — it tracks your growth
Honest — it logs your actions immutably
Extendable — you can build missions, tools, and reports into it
Transparent — its memory can be shared, verified, and validated

Whether you’re a beginner learning commands or a pro building a cyber toolkit, SecuriGotchi can evolve with you—literally.

✍️ Final Thoughts

SecuriGotchi began as a fun project—but it’s grown into a powerful system for logging, learning, and leveling up your security skills. And it’s only getting better.

If you’ve ever wanted a terminal pet that logs your exploits, signs your logs, and gives you XP for hardening your machine—this is it.

🧠 Live. Learn. Log. Secure.
