Announcing Treasures: Geocaching on Nostr
The world's first decentralized geocaching platform built on Nostr, bringing treasure hunting to the open web.
Today we're thrilled to announce Treasures, the world's first decentralized geocaching platform built on the Nostr protocol. Treasures brings the beloved treasure hunting hobby to the open web, free from the constraints and frustrations of centralized platforms.
What is Geocaching?
Geocaching is a real-world treasure hunting game where participants use GPS coordinates to find hidden containers (called "geocaches" or "caches") placed by other players. It's a global community activity that encourages exploration, adventure, and discovery in the physical world. With millions of geocaches hidden worldwide, it's one of the most popular outdoor recreational activities.
Geocaching is Overdue for an Update
The Problem with Centralized Platforms
- • Pay-to-play paywalls restrict access
- • Premium-only caches create inequality
- • Data lock-in traps your logs
- • Arbitrary restrictions limit innovation
- • Corporate control over community
The Decentralized Solution
- • Open protocol enables innovation
- • Community-driven development
- • No single point of failure
- • True data ownership via Nostr
- • Fully free, or fork it!
The Future of Geocaching is Decentralized
Join the world's first decentralized geocaching platform built on Nostr. Hide treasures, explore the world, and connect with adventurers worldwide—all without paywalls or platform lock-in.
Treasures: Nostr Geocaching
Treasures solves these problems by building geocaching on Nostr, a decentralized protocol that puts users in control. Unlike corporate-controlled platforms with paywalls and restrictions, Treasures returns geocaching to its roots as a free, open community activity. Here's what makes Treasures special:

- Pre-built Nostr integration patterns
- Responsive UI components optimized for mobile and desktop
- Built-in support for Nostr event types and relay management
- Streamlined development workflow for decentralized apps
MKStack represents the future of Nostr development - making it easier than ever to build powerful, user-friendly applications on the decentralized web.
Getting People Into the Real World
One of the most exciting aspects of Treasures is how it encourages people to disconnect from screens and explore the physical world. In an age of increasing digital isolation, geocaching provides:
- Physical Adventure: Real-world exploration and discovery
- Community Connection: Meeting fellow geocachers and sharing experiences
- Exercise & Health: Walking, hiking, and outdoor activity
- Local Discovery: Finding hidden gems and interesting locations in your area
- Family Activity: Fun for all ages and skill levels
Treasures taps into an existing, passionate IRL community of millions of geocachers worldwide. By bringing this community to Nostr, we're creating a bridge between the digital and physical worlds.
The Technical Foundation
Treasures implements a comprehensive Nostr-based geocaching protocol these event types:
- Geocache Listing Events (Kind 37515): Addressable events that contain all cache information including location, difficulty, terrain, size, and type. These events are owned and maintained by the cache creator.
- Found Logs (Kind 7516): Regular events that record when the cache is found.
- Log Comments (Kind 1111): Regular events that record other log comments including DNF reports, maintenance notes, and archive notifications.
This protocol ensures interoperability - any Nostr client can implement geocaching features and interact with Treasures data.

Join the Revolution
Treasures represents more than just a new geocaching platform - it's a demonstration of how decentralized technologies can solve real problems and empower communities. By choosing open protocols over closed platforms, we're building a more resilient, user-controlled future for geocaching that can never be captured by corporate interests or locked behind paywalls.
The treasure hunting community has always been about exploration, discovery, and sharing adventures. Geocaching was born as a free, open activity that brought people together through shared adventure. Corporate platforms have tried to monetize and restrict this natural human impulse, but with Treasures on Nostr, we can return to those original values while maintaining true ownership of our data and freedom from platform restrictions.
Every geocacher who joins Treasures is voting for a future where outdoor adventure remains accessible to everyone, regardless of their ability to pay subscription fees. Together, we can build a geocaching ecosystem that serves the community instead of extracting profit from it.
The world is full of hidden treasures, and they should be free for everyone to discover.
