Solana Price Oracle Node

A decentralized price aggregation oracle for the Solana ecosystem. This oracle node aggregates price data from multiple independent sources, applies advanced consensus algorithms, and publishes verified price feeds to the Solana blockchain. Built with Rust for maximum performance and security, it showcases enterprise-level distributed systems architecture.

Architecture

Core Components

• Oracle Node: High-performance Rust application with async/await patterns
• Consensus Engine: Weighted voting with outlier detection and Byzantine fault tolerance
• Data Sources: Multi-provider integration (CoinGecko, CoinMarketCap, Binance)
• Solana Program: On-chain price storage with cryptographic verification
• CLI Tools: Professional command-line interface for node management

Technical Highlights

• Advanced Rust: Complex async programming, error handling, cryptographic operations
• Blockchain Integration: Real Solana program deployment and transaction handling
• Distributed Systems: Consensus algorithms, data validation, fault tolerance
• Production Architecture: Modular design, comprehensive error handling, monitoring

Installation & Setup
