**Data Farming (DF) is Ocean's incentive program.** It rewards OCEAN to participants who lock OCEAN into veOCEAN, curate data, or 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 is organized into two streams: Passive DF and Active DF. Each has 50% of the DF budget. Passive DF allows for passive earning potential. Active DF requires more engagement; it has several substreams, each with its own activity.
Active DF's substreams can -- and do -- evolve over time. It's chronicled [here](https://blog.oceanprotocol.com/ocean-data-farming-series-c7922f1d0e45).
**[Reward Schedule](reward-schedule.md)**. The 150,000 OCEAN / week currently available for DF rewards will increase over time to over 1.1M OCEAN / week.
**[Yields](apys.md)**. Historically, APYs are 5-15%. APYs vary week to week. APY depends on total OCEAN staked, duration of OCEAN lock, DCV, what DF streams you participate in, and other factors.
## Networks
OCEAN rewards for all DF streams & substreams are on Ethereum mainnet. One exception: rewards for Predictoor DF are on Oasis Sapphire.
Users engage in different networks, depending on the DF stream:
- Passive DF: veOCEAN is deployed on Ethereum mainet. Users lock OCEAN for veOCEAN on Ethereum mainnet
- Volume DF: users can allocate veOCEAN to data assets on Etherum mainnet, Polygon, BSC, Moonriver, Energy Web Chain, or Sapphire.
- Challenge DF: users submit predictions on Mumbai (Polygon testnet).
- Predictoor DF: users submit predictions on Sapphire.
The [networks docs](../discover/networks/README.md) have more info about networks.
- The [Ocean Data Farming Series](https://blog.oceanprotocol.com/ocean-data-farming-series-c7922f1d0e45) blog has a chronological account of all Data Farming activities since its inception. It links to related blog posts.
