Though extra advanced than publish-subscribe designs, request-response oracles are essentially what we explained inside the previous part. The oracle can have an on-chain component that gets an information request and passes it to an off-chain node for processing.

Ethereum and its applications are clear and open up resource. You can fork code and re-use functionality Other individuals have already designed.
