**Data Farming (DF) is Ocean's incentive program.** It rewards OCEAN to participants who lock OCEAN into veOCEAN, curate data, and make predictions -- all in the name of driving **data consume volume** (DCV). DF is a bit like DeFi liquidity mining, but tuned for DCV.
**DF's main streams are Passive DF and Active DF.** The former allows for passive earning potential, and the latter requires more engagement. Each has 50% of the DF budget.
**[Yields](apys.md)** Typical reward APYs are 5–20%, but may be as high as 45% and as low as 1%. APYs will vary week to week. APY depends on total OCEAN staked, duration of OCEAN lock, DCV, what DF streams you participate in, and other factors.
Active DF's substreams can -- and do -- evolve over time. It's chronicled [here](https://blog.oceanprotocol.com/ocean-data-farming-series-c7922f1d0e45).
