Oracle

Stork is an oracle protocol that enables ultra-low latency connections between data providers and both on-chain and off-chain applications. Stork is implemented as a pull oracle and supports automated on-chain delivery. Stork continuously aggregates, verifies, and audits data from trusted publishers, and makes that aggregated data available at sub-second latency and frequency.

You can fetch all these datapoints using Stork on Horizen. And for most of the usecases on Horizen, we will be using a consumer based data model with Stork. As Stork is a pull based oracle, all the feeds are not maintained on-chain. Based on the demand of the applications anyone can publish verifiable data feeds for any data pools supported by Stork.

• You can fetch the required data directly using Stork REST API
• Then you can push these feeds to Stork contracts using updateTemporalNumericValuesV1
• Lastly you can fetch the data feeds onchain by interacting with getTemporalNumericValueV1

Here's an example project on consuming data feeds onchain, Stork EVM SDK Example
