Compound price feed [in progress]

This post is part of our Oracles Study Group. Take a look there to learn more about related topics.

The Compound Open Price Feed is a system to allow various sources to sign off-chain data about prices and allow any Ethereum account to move that data on-chain.1

It has a price storage contract that stores prices signed by any address, and another contract that only stores prices within an acceptable bound of the Uniswap time-weighted average price and are signed by a reporter2.

Currently, Coinbase Pro is the reporter.
