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).
First, you will need solc 0.6.6 installed.
Additionally for testing, you will need TypeScript installed and will need to build the open-oracle-reporter project by running cd sdk/javascript && yarn.
To fetch dependencies run:
yarn install
To compile everything run:
yarn run compile
To deploy contracts locally, you can run:
yarn run deploy --network development OpenOraclePriceData
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 deploy MyView arg1 arg2 ...
To run tests:
yarn run test
To track deployed contracts in a saddle console:
yarn run console
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...
