Mostro Score Web

A web-based reputation analysis tool for Mostro P2P Lightning nodes. This application fetches public Nostr events and computes objective metrics to help users assess the reliability and operational health of Mostro nodes before trading.

Features

• Client-side computation: All metric calculations run in the browser using JavaScript
• Nostr integration: Connects directly to Nostr relays via WebSocket
• Comprehensive metrics: Implements the full Mostro Reputation System Specification v1.1

Metrics Computed

Section	Metrics
Longevity	First activity date, days active
Liveness	Last trade timestamp, days since last trade, activity status
Recent Activity	Trades in last 7/30/90 days
Activity Consistency	Active days (last 30d), max inactive gap
Cumulative Performance	Total successful trades, total volume (sats/BTC)
Trade Statistics	Min/max/mean/median trade amounts
Trust Score	Composite score (0-100) based on age, volume, and trade count

Requirements

• Rust (for building the server)
• A modern web browser with JavaScript enabled

Installation

git clone https://github.com/MostroP2P/mostro-score-web.git
cd mostro-score-web
cargo build --release

Usage

Start the server:

cargo run --release

Open your browser to http://localhost:3000

Enter a Mostro node's public key (npub or hex format) and optionally specify custom relays, then click "Analyze".

• Server (Rust/Axum): Serves static files only
• Client (JavaScript): Connects to Nostr relays, fetches events, computes metrics, displays results

Data Sources

The tool analyzes two types of Nostr events published by Mostro nodes:

1. Development Fee Events (kind 8383)

   • Tags: z=dev-fee-payment, y=mostro
   • Used to determine when the node started trading

2. Order Events (kind 38383)

   • Tags: z=order, s=success
   • Used to calculate trade metrics and activity

Trust Score Calculation

The trust score (0-100) is computed as:

• Age (max 30 points): Scales linearly up to 1 year of activity
• Volume (max 40 points): Scales linearly up to 1 BTC total volume
• Trade Count (max 30 points): Scales linearly up to 100 successful trades
