Zcash Tunnels of Privacy
Privacy matters. Gaming should too.
The problem Zcash Tunnels of Privacy solves
Problem it Solves:
The Problem: Privacy Education is Boring, Gaming is Surveillance
Traditional cryptocurrency education fails to engage users meaningfully. Meanwhile, modern gaming has become a surveillance nightmareโtracking every click, monetizing player data, and requiring always-online connections to corporate servers.
Tunnels of Privacy solves both problems at once.
๐ฎ What It Does
A fully self-hosted, privacy-first gaming experience that teaches Zcash and financial privacy concepts through engaging gameplay:
Tunnels of Privacy โ A dungeon crawler RPG with turn-based combat, 99 unique bosses, AI-powered NPC conversations, and 4-player co-op multiplayer
ZLOCK ZHAINER โ A 3D arcade puzzle game (Lumines/Columns-inspired) with chain combos and special abilities
๐ Why It Matters

Games require accounts & logins No accounts needed โ just download and play
Multiplayer requires corporate servers Self-hosted WebSocket server โ you control the infrastructure

Games are bloated with dependencies Single HTML files โ no build step, no npm, just open in browser

Challenges I ran into
Challenges I Ran Into
๐ซ** No Programming Background**
Built entirely through vibe coding with AI assistants. The challenge was learning to communicate precisely enough to get working code โ and catching when AI "fixed" things by breaking other features.
๐ค LLM Integration
Supporting both local (Ollama) and cloud (OpenRouter) AI providers with graceful fallback when neither is available.
๐ฅ 4-Player Multiplayer
WebSocket state synchronization across multiple clients. Host-authoritative architecture โ most bugs were server relay issues, not client code.
๐** Zero Infrastructure**
No backend, no database, no accounts. Everything runs client-side or self-hosted. Single HTML files, localStorage saves, user-hosted servers. TTS for text to voice and other features.
