A Trusted Oracle is a mechanism used to link blockchain networks with external data sources. It acts as a bridge, enabling smart contracts to interact with real-world information that is not directly available on the blockchain.These oracles gather data from various sources, such as financial markets, weather conditions, or sports scores, and deliver this information to the blockchain. This allows smart contracts to execute tasks based on real-time data, expanding their functionality beyond just on-chain data.To maintain reliability and security, Trusted Oracles are often operated by reputable entities. Users rely on these oracles to provide accurate and tamper-proof information. However, their centralization can pose risks, as they may become a single point of failure if compromised.In summary, Trusted Oracles play a crucial role in enhancing the capabilities of smart contracts by providing essential external data while balancing the need for reliability and security.
