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) that include on-chain and off-chain price feeds.
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
This repository contains a set of SDKs for reporters to easily sign "reporter" data in any supported languages. We currently support the following languages:
- JavaScript (in TypeScript)
- Elixir
The poster is a simple application that reads from a given feed (or set of feeds) and posts...
