External feeds are data streams originating from sources outside a blockchain network, providing real-world information to smart contracts. These feeds are crucial for decentralized applications that require off-chain data, such as price information, event outcomes, or identity verification. Oracles commonly facilitate the secure delivery of this external data. Their accuracy is vital for smart contract reliability.
Context
The integrity and security of external feeds represent a critical area of focus for decentralized finance and blockchain utility. Discussions frequently address the risks associated with data manipulation and the need for robust oracle networks to ensure data authenticity. Future developments will likely involve advanced cryptographic proofs and decentralized oracle protocols to enhance trustless data delivery.
