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.

P2P Market Data

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
