Oracle Integration refers to the process of connecting blockchains with external data sources, enabling smart contracts to interact with real-world information. Since blockchains are inherently isolated and cannot access off-chain data directly, oracles serve as a bridge.These oracles pull data from various sources such as APIs, traditional databases, and other services. Common uses include fetching price feeds, weather data, or sports scores, which can trigger actions within smart contracts based on predefined conditions.There are different types of oracles, such as centralized oracles, which rely on a single source, and decentralized oracles, which aggregate data from multiple sources to enhance trust and reliability. The integrity of the data provided by oracles is crucial, as inaccurate or manipulated information can lead to unintended consequences in smart contracts.Overall, Oracle Integration is essential for expanding the functionality of smart contracts and decentralized applications, allowing them to respond to changing real-world events and conditions effectively.
