Religant was a decentralized oracle service designed to provide accurate and up-to-date price data feeds on the Radix network.
Functionality
The Religant Oracle protocol operated by aggregating data from various sources. A network of data nodes queried exchanges for current transaction data and submitted this information to a contract. This contract employed a consensus mechanism to determine the aggregate price. Data nodes, running the Religant node backend software, updated the feed at regular intervals or when the new aggregate price exceeded a specified divergence threshold, currently set at 2%. This threshold ensured that the rate from the Religant oracle's feed remained within 2% of actual transaction rates on exchanges.
Component API
The user-facing API of the Religant Oracle was straightforward, consisting of a single method, get_price, which returned a PriceData structure containing the current XRD/USD exchange rate and a timestamp. The Option wrapper in the return type ensured type safety, with the method usually returning a valid result after the initial round of Oracle feed aggregation.
Integration Guide
Integrating the Religant Oracle into an application required several steps:
- Defining the
PriceDatastructure outside of the application blueprint, using various traits and types likeScryptoSbor,USDValue, andPOSIXTime. - Declaring the component's API within the blueprint module using an
extern_blueprint!macro. - Instantiating a reference to the global Religant component within the blueprint.
- Using the Religant component's methods within the application, such as retrieving the current exchange rate and minting tokens based on this rate.
Status
Religant is no longer operational — the project's website (religantoracles.com) no longer resolves and the oracle feed has been discontinued. The Scrypto integration example published by MLabs remains available as a reference. For active oracle infrastructure on Radix, see OTER, an optimistic oracle launched on the network.
