Definition ∞ An On-Chain Data Feed provides real-time or near real-time information directly recorded and stored on a blockchain. This data, which can include asset prices, transaction volumes, or smart contract states, is verifiable and immutable, offering a high degree of transparency and integrity. Such feeds are crucial for decentralized applications (dApps) and smart contracts that require external data to execute their logic. They ensure data reliability for decentralized systems.
Context ∞ News frequently discusses the importance of robust on-chain data feeds for the security and functionality of decentralized finance (DeFi) protocols. Debates often center on the decentralization and reliability of oracle networks, which supply this data to blockchains, and the potential for manipulation if feeds are compromised. The continuous development of secure and accurate on-chain data solutions is critical for the stability and trustworthiness of the entire digital asset ecosystem.
