Detailed Description

Price Oracle is a system that acts as a bridge between a blockchain network and the external world, providing off-chain price data to decentralized applications (dApps) on the blockchain.

This implementation conforms to the requirements specified in the XLS-47d.

The SetOracle transactor implements creating or updating Oracle objects.
