Oracle Protocol refers to a system that connects smart contracts with real-world data sources. Smart contracts are self-executing contracts with the terms directly written into code. However, they often require external information to function correctly, such as price feeds, weather data, or event outcomes.Oracles act as intermediaries that fetch, verify, and deliver this external data to the smart contract. They ensure that the contract can execute its terms based on accurate and timely information. There are different types of oracles, including centralized and decentralized versions. Centralized oracles rely on a single source of data, which can introduce vulnerabilities. In contrast, decentralized oracles pull data from multiple sources, enhancing security and reliability.Oracle Protocols are essential for broadening the functionality of smart contracts, enabling them to interact with the outside world effectively. This capability opens new possibilities for decentralized applications, ranging from finance and insurance to gaming and supply chain management.
