P2P Market Data

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

Stil 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

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
