Reflector is highlighted as a crucial tool in the Stellar ecosystem, offering real-time, tamper-proof price feeds to Soroban-based smart contracts by aggregating on- and off-chain data. The tutorial guides users to create a smart contract that predicts Euro price fluctuations over five minutes, connecting to Reflector for real-time data access. Users place bets using XLM, while functions within the contract verify predictions and reward correct guesses by doubling the bet amount. The tutorial emphasizes on the interaction between oracles and smart contracts, exploring their potential for creating prediction markets and DeFi applications on the Stellar network. Storage types in Soroban are explained, emphasizing data handling and the use of Rust structs for complex data management. This tutorial showcases utilizing Stellar’s blockchain for constructing data-driven applications with real-world relevance.
