-#### What are Active Rewards?
+#### What are Active Rewards and Substreams?
 
-Active rewards are OCEAN rewards paid to Data Farmers that allocate their veOCEAN tokens to Ocean ecosystem assets. They're called Active rewards because the amount of rewards relies on the active participation of the Data Farmer to select and allocate veOCEAN to these assets. **Active rewards yield depends on the sales of allocated assets.** No sales = no rewards, so choose your favorites wisely & then allocate. Always DYOR.
+Active Rewards are OCEAN rewards paid to contributors actively working to improve Ocean Protocol. To better reflect this, there are are multiple reward substreams avaialble:
+1. Volume DF
+2. Challenge DF
 
-Active rewards are governed and defined by the [Reward Function](df-max-out-yield.md#reward-schedule).
+Volume DF rewards Data Farmers that allocate their veOCEAN tokens to Ocean ecosystem assets. It's called Volume DF because the amount of rewards relies on Data Farmers allocating veOCEAN to assets that are actively generating Data Consume Volume. Therefore, **Volume DF yields depend on the allocations made and sales produced by these assets.** No sales = no rewards, so choose your favorite datasets wisely & then allocate. Always DYOR.

+Challenge DF rewards Data Scientists that produce prediction models that consistently improve the prediction of the price of Ethereum. It's called Challenge DF because weekly rewards are dispensed towards participants that are competing to improve the accuracy of how well we can predict price movements of Ethereum. Therefore, **Challenge DF yields depend on participants accurately outcompeting each other.** Only the top 3 predictions on the leaderboard win.

 #### Splitting the Pie
 
-Each Data Farming weekly round has a pool of OCEAN rewards, and 50% of the pool is paid out in the form of passive rewards & 50% in the form of active rewards.

+##### Reward Sub-Streams
+**Active Rewards** is then composed of two sub-streams.
+
+1. 5,000 OCEAN is paid out to Challenge DF.
+2. The remainder is paid out to Volume DF.

-Data Farming strongly incentivizes publishing assets in the Ocean ecosystem by giving double the active rewards to Data Farmers that allocate to their own published assets.
+Data Farming strongly incentivizes publishing assets in the Ocean ecosystem by doubling the allocation power of Data Farmers that support their own published assets.
 
-How is it calculated? _All the veOCEAN a Data Farmer has allocated to an asset they’ve published is **doubled for the rewards calculation.**_

 ### Challenge DF Substream
 
-If you are a data scientist and enjoy tackling challenging problems, this is the perfect place for you. The Challenge DF provides a weekly challenge where you can test your skills in predicting the price of Ethereum. Compete against other participants to earn a place on the podium and receive a share of the available rewards.

Challenge DF provides a weekly competition where you can test your skills in predicting the price of Ethereum. Rise against other participants to earn a place on the podium and receive a share of the available rewards.
 
 This opportunity allows you to explore the capabilities offered by Ocean Protocol and gain valuable exposure. As your models and skills improve, you can publish your models on the main network and begin monetizing your work.
