Oracle Network

Definition ∞ An oracle network provides external real-world data to blockchain smart contracts, enabling them to react to events outside their native environment. These decentralized networks aggregate and verify off-chain information, such as price feeds or weather data, for on-chain consumption. Without oracles, smart contracts cannot access data beyond the blockchain itself, limiting their utility. They are critical for the functionality of many decentralized applications.
Context ∞ A significant discussion within oracle networks revolves around data integrity, censorship resistance, and the economic incentives for honest data provision. The security of these networks is paramount, as compromised data feeds can lead to substantial financial losses in dependent smart contracts. Future developments will likely focus on improving decentralization, cryptographic proofs for data authenticity, and the scalability of data delivery mechanisms.
