--- id: task-037 title: zkGPS Location Games and Discovery System status: To Do assignee: [] created_date: '2025-12-05 00:49' labels: - feature - open-mapping - games - zkGPS dependencies: [] priority: high --- ## Description Build a location-based game framework combining zkGPS privacy proofs with collaborative mapping for treasure hunts, collectibles, and IoT-anchored discoveries. Use cases: - Conference treasure hunts with provable location without disclosure - Collectible elements anchored to physical locations - Crafting/combining discovered items - Mycelial network growth between discovered nodes - IoT hardware integration (NFC tags, BLE beacons) Game mechanics: - Proximity proofs ("I'm within 50m of X" without revealing where) - Hot/cold navigation using geohash precision degradation - First-finder rewards with timestamp proofs - Group discovery requiring N players in proximity - Spore collection and mycelium cultivation - Fruiting bodies when networks connect Integration points: - zkGPS commitments for hidden locations - Mycelium network for discovery propagation - Trust circles for team-based play - Possibility cones for "reachable discoveries" visualization ## Acceptance Criteria - [ ] #1 Discovery anchor types (physical, virtual, IoT) - [ ] #2 Proximity proof verification for discoveries - [ ] #3 Collectible item system with crafting - [ ] #4 Mycelium growth between discovered locations - [ ] #5 Team/group discovery mechanics - [ ] #6 Hot/cold navigation hints - [ ] #7 First-finder and timestamp proofs - [ ] #8 IoT anchor protocol (NFC/BLE/QR)
