OTHub Runtime is a community managed NodeJS backend specifically built to work in tandem with the othub-react and otp-sync repositories. It is a critical infrastructure for OTHub.
- Facilitates all current and future data requests between OTHub's front end, othub-react and the MySQL database maintained by otp-sync;
- Generates API keys required to request data from othub-api;
- Faciliates all DKG get/publish requests via the dkg.js SDK to an OTHub hosted node for both Mainnet and Testnet;
Warning
Please be aware that the instructions below are for users with a fully synchronized OriginTrail Parachain blockchain by using otp-sync or any other indexing method which is required to run this backend.
