- 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.

### Estimating Passive DF APYs
-To make it easier to estimate your APY, [we have created a simple spreadsheet](https://docs.google.com/spreadsheets/d/1zzuW5pBbX6j6hZL_XtJDtSR2-rDHa_LGOEwgoQ4D8lk/edit?usp=sharing) that let's you easily estimate your Passive APY.
+The [Passive DF page](https://df.oceandao.org/passive-df) estimates profit & APY for you, as you explore different values of # OCEAN, lock time, and number of compounds. It accounts for gas costs.
-We have provided 2 sheets as an example of locking-up 10,000 OCEAN for:
-1. A 4-year investment period
-2. A 6-mo investment period
-
-The above are simplified examples meant for everyone to understand. They are naive investment strategies and are meant to provide you, the reader, with some examples to build upon. You can use these as a reference to create your own plan, so feel free to make a copy of this spreadsheet and customize it to your needs and wants.
+You'll find that if # OCEAN is too small or lock time is too short, profit and APY will be <0 because gas fees will overwhelm rewards. Conversely, higher OCEAN locked and longer lock times will make APY larger.

-Challenge DF requires no OCEAN locked or staked, yet provides rewards if you win the prediction game. Therefore theoretically APY is infinity. We ignore Challenge DF for APY discussion.

### Estimating Predictoor DF APYs

[2] We modeled OCEAN locked by observing linear growth from DF week 5 (when OCEAN locking was introduced) to week 28: OCEAN locked grew from 7.89M OCEAN to 34.98M OCEAN respectively, or 1.177M more OCEAN locked per week. The true values of OCEAN locked was last updated on DF week 29. For more accuracy, that could be updated to the values since then.

-
-## Predict to earn
-
-By participating in the weekly data challenges of predicting the price of Ethereum, you will become familiar with the Ocean Protocol stack and with building predictions that can be sold for money.
-
-These are the steps to get involved:
-
-#### Step 1 - Navigate to the Data Farming dApp
-
-Go to [Data Farming dApp](https://df.oceandao.org)
-
-#### Step 2 - Go to the "Challenges" page
-
-After the dApp loads, look for the menu and click on "Challenges"
-
-
Find "Challenges" in the menu and click on it
-
-#### Step 3 - Click on "Participate"
-
-After clicking on "Participate" you will be [linked to the Challenge DF README](https://github.com/oceanprotocol/predict-eth/blob/main/challenges/challenge-df.md) that outlines all details about the challenge.
-
-
Click the Participate button
-
-#### Step 4 - Use README to publish your predictions
-
-You can see the ongoing challenge right away together with some key informations such as submission deadline and available rewards.
-
-Follow the README steps to publish your model and compete in the challenge.
-
-
How to submit Challenge DF
-
-#### Step 5 - Check weekly results
-
-Challenge DF weekly results become available at the end of every Data Farming round and can be viewed in the Challenges page.
-
-The top 3 competitors win prizes and are visible in the leaderboard.
-
-
Past Challenges leaderboard
-
-#### Step 6 - View and claim Active Rewards.
-
-To view and claim your rewards:
-
-1. Make sure your wallet is connected.
-2. Your Challenge DF substream rewards will be displayed to the left besides "rewards". As you can see, it will be added to other active rewards that can be claimed besides "total rewards".
-3. To claim all Active Rewards including your Challenge DF rewards, simply click on the "Claim Rewards" button.

-
-**This page** is about Challenge DF, and [this page](challengedf-guide.md) is a guide.
-
-## About Challenge DF
-
-Challenge DF rewards data scientists for making predictions for future ETH price. It's a weekly challenge.
-
-## Publish prediction models and earn rewards
-
-**Prizes:**
-
-Prize Pool: 1,000 OCEAN (as of Nov 2, 2022)
-
-- 1st Place - 500 OCEAN
-- 2nd Place - 300 OCEAN

-
-- A fresh challenge begins and concludes every Thursday
-- You have to submit your entry before the deadline.
-- At the beginning of each week, a predetermined amount of OCEAN is allocated as rewards.
-- Competitors need to submit 12 predictions by using a DataNFT to share data.
-- The rewards are divided into specific amounts for the top three positions.
-- The individuals who submit the top three entries will receive rewards, and their wallet addresses will be showcased within the Data Farming dapp.
-
-### What do I gain from this?
-
-- Earn OCEAN rewards, [claimable inside the app](https://df.oceandao.org/rewards)
-- Gain in-depth knowledge of the Ocean Protocol stack.
-- Increase your visibility by achieving a place on the podium.
-- Create valuable assets that can be monetized on the Ocean Marketplace.
-- Enhance your skills and engage in friendly competition with other participants.
