# FAQ

## Data Farming FAQ
<details>
<summary>What assets are eligible for Data Farming?</summary>

The data asset may be of any type — dataset (for static URIs), algorithm for Compute-to-Data, or any other Datatoken token-gated system. The data asset may be fixed price or free price. You can find more details in the [DF Background page](df-background.md#data-assets-that-qualify-for-df)
</details>

<details>
<summary>When exactly does counting start and finish, for a given week?</summary>

The counting starts at 12.01am on Thursday, and ends at 11.59pm on the following Wednesday.
</details>

<details>
<summary>I staked for just one day. What rewards might I expect?</summary>

At least 50 snapshots are randomly taken throughout the week. If you’ve staked just one day, and all else being equal, you should expect 1/7 the rewards compared to the full 7 days.
</details>

<details>
<summary>The datatoken price may change throughout the week. What price is taken in the DCV calculation?</summary>

The price is taken at the same time as each consume. E.g. if a data asset has three consumes, where price was 1 OCEAN when the first consume happened, and the price was 10 OCEAN when the other consumes happened, then the total DCV for the asset is 1 + 10 + 10 = 21.
</details>

<details>
<summary>Can the reward function change during a given week?</summary>

No. At the beginning of a new DF round (DF1, DF2, etc), rules are laid out, either implicitly if no change from previous round, or explicitly in a blog post if there are new rules. This is: reward function, bounds, etc. Then teams stake, buy data, consume, etc. And LPs are given DF rewards based on staking, DCV, etc at the end of the week. Overall cycle time is one week.

Caveat: it’s no at least in theory! Sometimes there may be tweaks if there is community consensus, or a bug.
</details>

## veOCEAN FAQ
<details>
<summary>What is the official formula for the Linear Decay?</summary>

The Linear Decay formula for veOCEAN can be expressed as follows in python.  
```python
FOUR_YEARS = 60 * 60 * 24 * 7 * 52

veOcean_balance = OCEAN_amount_locked * (your_unlock_timestamp — current_unix_timestamp ) / FOUR_YEARS
```

</details>

## Staking FAQs
<details>
<summary>What about passive stakers — people who just want to stake in one place and be done?</summary>

Earnings are passive by default
</details>

<details>
<summary>What about active stakers — people who want to do extra work and get rewarded?</summary>

Ot works. Half the DF revenue goes to veOCEAN stake that users can allocate. Allocate well → more $$
</details>

## Pricing FAQs
<details>
<summary>In this scheme, can people stake on fixed-price datasets?</summary>

Yes. They allocate their veOCEAN to datasets. Then DF rewards follow the usual DF formula: DCV * veOCEAN stake.
</details>

<details>
<summary>In this scheme, can people stake on free datasets?</summary>

Yes. They allocate their veOCEAN to datasets. Then DF rewards follow the usual DF formula: DCV * veOCEAN stake. Except in this case although DCV is 0, the gas fees will still count towards calculating rewards.
</details>

<details>
<summary>Does this work for other pricing schemes?</summary>

Yes, from the get-go! It doesn’t matter how data is priced, this works for all schemes.
</details>

## Chains FAQ
<defailts>
<summary>Which networks are eligible for DF?</summary>
Data assets for DF may published in any network where Ocean’s deployed in production: Eth Mainnet, Polygon, BSC, and more.

You can find a list of [all supported chains here](https://docs.oceanprotocol.com/core-concepts/networks).
</details>

<details>
<summary>Which chain is veOCEAN be deployed on?</summary>

[veOCEAN & DF](https://github.com/oceanprotocol/contracts/tree/main/contracts/ve) core contracts are deployed on Ethereum mainnet and allow users to allocate veOCEAN tokens to any asset, on any chain.
</details>

<details>
<summary>Where can I find the veOCEAN and DF contracts?</summary>

They are deployed on Ethereum mainnet, alongside other Ocean contract deployments. You can find the [full list of contracts here](https://github.com/oceanprotocol/contracts/blob/main/addresses/address.json).
</details>

<details>
<summary>What is the official veOCEAN epoch start_time?</summary>

veFeeDistributor has a start_time of 1663804800 (Thu Sep 22 2022 00:00:00)
</details>

<details>
<summary>Will the Market still need to be multi-chain?</summary>

Yes, Ocean Market still needs to be multi-chain: all the reasons that we went multi-chain for are as valid as ever.
</details>

<details>
<summary>Which chain supports Fixed Price Assets?</summary>

You can publish Fixed Price Assets to any chain that Ocean supports.
