On-Chain Data Feeds

Definition ∞ On-chain data feeds refer to streams of information that are directly recorded and verifiable on a blockchain ledger. This data can include transaction details, smart contract states, or other metrics native to the blockchain itself. Unlike off-chain data, which requires oracles for verification, on-chain data is inherently transparent and immutable. It provides a foundational source of truth for decentralized applications and protocols.
Context ∞ On-chain data feeds are fundamental for the operation of decentralized finance applications, providing the raw information necessary for price discovery, collateral management, and protocol logic. News often discusses new analytical tools that leverage this data or improvements in blockchain explorers that make it more accessible. The integrity and real-time availability of these feeds are critical for the security and functionality of the digital asset ecosystem.
