Chainlink
Funcionalidade do Oráculo DON
Context
This figure appears in the Introduction section during the explanation of Decentralized Oracle Networks (DONs). It introduces DONs as the foundational concept of Chainlink 2.0, illustrating how a committee of oracle nodes cooperates to fulfill basic oracle functions. The figure accompanies the section's first concrete description of how a DON operates at a high level.
What This Figure Shows
The figure conceptually shows how a Decentralized Oracle Network can realize traditional oracle functionality by relaying off-chain data to a smart contract on a blockchain. An executable running on the DON uses adapters (shown as small blue boxes) to fetch off-chain data, performs computation on it, and then forwards the output via another adapter to a target blockchain. Arrows indicate the direction of data flow for this particular use case. The DON's local storage allows the executable to persist state and communicate with other executables, enabling more sophisticated operations such as computing trailing averages rather than merely forwarding raw data.
Significance
This figure establishes the conceptual baseline for DON functionality, showing that even the most basic oracle operation—data relay—benefits from the DON's networking, computation, and storage resources. It frames all subsequent DON capabilities as extensions of this foundational pattern, making the architecture's generality easier to grasp.
