Nostr Protocol Documentation

This section contains technical documentation related to the Nostr protocol implementation in the POWR app.

Key Documents

• Exercise NIP Specification - Nostr Implementation Possibility for exercise and workout data
• Encoding and Decoding - NIP-19 encoding and decoding processes

Nostr Protocol Overview

The Nostr protocol provides a decentralized social networking protocol that underpins the social features of the POWR app. Key aspects include:

• Relay-based message distribution
• Public key cryptography for identity
• Event-based data model
• NIP standards for interoperability

Implementation in POWR

Our implementation of Nostr follows these key principles:

1. Privacy-first approach with user control
2. Offline-first with queued publishing
3. Support for standard and extended event kinds
4. Proper event signing and verification
5. Relay management for optimal connectivity
