 The pool rewards calculation and also the treasury calculation requires a data provider to perform the calculation.
 This repository offers different data providers and also an interface if you want to add your own provider. The following data providers are available:
 
- - [Koios Data Provider](./src/main/java/org/cardanofoundation/rewards/calculation/data/provider/KoiosDataProvider.java)
- - [JSON Data Provider](./src/main/java/org/cardanofoundation/rewards/calculation/data/provider/JsonDataProvider.java)
- - [DbSync Data Provider](./src/main/java/org/cardanofoundation/rewards/calculation/data/provider/DbSyncDataProvider.java)
