The Compound Open Oracle

Open Oracle

The Open Oracle is a standard and SDK allowing reporters to sign key-value pairs (e.g. a price feed) that interested users can post to the blockchain. The system has a built-in view system that allows clients to easily share data and build aggregates (e.g. the median price from several sources).

Contracts

First, you will need solc 0.5.10 installed. Additionally, you will need TypeScript installed and will need to build the project by running tsc.

To compile everything run:

yarn run compile

To compile just the contracts run:

yarn run saddle:compile

To deploy the Open Oracle locally, you can run:

yarn run saddle:deploy --network development Oracle

Note: you will need to be running an Ethereum node locally in order for this to work. E.g., start ganache-cli in another shell.

You can add a view in MyView.sol and run (default is network=development):

yarn run saddle:deploy MyView arg1 arg2 ...

To run tests:

yarn run test

Poster
