P2P Market Data

A decentralized platform for sharing and validating financial market data across a peer-to-peer network.

Still WORK IN PROGRESS

Overview

P2P Market Data enables secure, distributed sharing of financial market data between trusted peers. It uses blockchain-inspired consensus mechanisms to validate data integrity and source reputation.

Features

• Decentralized P2P network for data sharing
• Real-time market data validation
• Reputation-based peer scoring
• Data integrity verification
• Configurable data sources
• Dark/light theme support

Tech Stack

• Frontend: React + TypeScript + Vite
• Backend: Go
• UI Components: shadcn/ui
• P2P Network: libp2p
• Desktop: Wails
• Database: PostgreSQL

Installation

# Clone repository
git clone https://github.com/danielsobrado/p2p_market_data.git
cd p2p_market_data

# Install dependencies
go mod download
cd frontend && npm install

# Build frontend assets (required by Go embed)
cd frontend && npm install && npm run build && cd ..

# Setup database schema (only needed if you are managing Postgres outside the app)
for f in sql/schema/*.sql; do psql -U postgres -d market_data -f "$f"; done

Usage

# Development
wails dev

# Build
wails build

When the Wails app starts its embedded PostgreSQL instance, it now initializes the required schema automatically.

Process Details

Data Flow

• External market data sources feed by using scrapping scripts (Can be shared)
• Scheduler orchestrates data collection timing
• Repository handles persistence and retrieval
• P2P network enables decentralized data sharing
• Frontend displays data through Backend API

Validation Flow

• Collected data is broadcast to P2P network
• Peers validate data authenticity and accuracy (Voting)
• Consensus mechanism confirms validation
• Peer reputation scores updated based on accuracy

Storage

• Validated market data stored in PostgreSQL
• Peer network information persisted in PostgreSQL
• System configuration managed via YAML files
