Data Farming (DF) is Ocean Protocol's **incentive system for curating high quality assets on the Ocean Market.** Participants vote on the Ocean Market assets that they believe are high quality and likely to sell. If they are right, then these Data Farmers **get a portion of the Ocean Market sales of the assets** they voted on!
(If you are familiar with 'liquidity mining', then you will find that Data Farming is similar but tuned instead for the curation of high quality assets on the Ocean Market.)
Unlike yield farming in DeFi, data farming has real intrinsic utility for Ocean Protocol stakeholders: as Data Farmers determine which are the highest quality assets on the Ocean Market to purchase, then the Data Farmers earn active OCEAN rewards when these assets sell. It's this **curation of the "best" assets on the Ocean Market** that shortens the search times for those looking to shop on the Ocean Market. We also put in place an incentive system for Publishers of assets to gain **2x the rewards** in Data Farming, thus driving forward the addition of great assets on the OM.
Every week OCEAN rewards are paid out to Data Farmers in two different ways: **passive** rewards and **active** rewards. The two reward functions produce different variable APYs. 
Active rewards are OCEAN rewards paid to Data Farmers that allocate their veOCEAN tokens to Ocean Market 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.
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.
Data Farming strongly incentivizes publishing assets on the Ocean Market by giving double the active rewards to Data Farmers that allocate to their own published assets.
