Verifiable Data Streaming

Definition ∞ Verifiable data streaming refers to the process of transmitting continuous flows of information in a manner that allows recipients to cryptographically confirm the integrity and authenticity of the data at any point. This ensures that the streamed data has not been tampered with and originates from a legitimate source. It is crucial for decentralized applications that rely on real-time external data feeds, such as oracle services or financial market data. This capability guarantees data trustworthiness in dynamic environments.
Context ∞ News related to blockchain oracles, decentralized finance (DeFi), and real-time data feeds often discusses verifiable data streaming. The focus is on ensuring that off-chain data brought onto a blockchain remains secure and unaltered, preventing manipulation that could impact smart contract execution. Innovations in this area are vital for the reliability and security of decentralized applications interacting with external information.
