On-chain oracles are decentralized services that provide external, real-world data to smart contracts operating on a blockchain. They act as bridges, fetching information from off-chain sources and securely delivering it to the blockchain for use in decentralized applications. These services are vital for enabling smart contracts to interact with external events and data.
Context
The reliability and security of on-chain oracles are subjects of continuous scrutiny, particularly as decentralized finance applications become more sophisticated. Key discussions involve the prevention of data manipulation, the decentralization of oracle networks, and the cost-effectiveness of data feeds. The performance and integrity of these oracle systems directly influence the trustworthiness of numerous blockchain-based applications.
