# Data Scientists
### How does Ocean benefit data scientists?
It offers three main benefits:
* **Earn.** You can earn $ by doing crypto price predictions via [Predictoor](/predictoor.md), by curating data in [Data Farming](/data-farming.md), competing in a [data challenge](/data-scientists/join-a-data-challenge.md), and by selling data & models.
* **More Data.** Use [Compute-to-Data](/developers/compute-to-data.md) to access private data to run your AI modeling algorithms against, data which was previously inaccessible. Browse [Ocean Market](https://market.oceanprotocol.com) and other Ocean-powered markets to find more data to improve your AI models.
* **Provenance.** The acts of publishing data, purchasing data, and consuming data are all recorded on the blockchain to make a tamper-proof audit trail. Know where your AI training data came from!
### How do data scientists start using Ocean?
Here are the most relevant Ocean tools to work with:
* The [**ocean.py**](https://github.com/oceanprotocol/docs/blob/main/data-scientists/ocean.py) library is built for the key environment of data scientists: Python. It can simply be imported alongside other Python data science tools like numpy, matplotlib, scikit-learn and tensorflow. You can use it to publish & sell data assets, buy assets, transfer ownership, and more.
* Predictoor's [**pdr-backend repo**](https://github.com/oceanprotocol/pdr-backend) has Python-based tools to run bots for crypto prediction or trading.
* [**Compete in a data challenge**](/data-scientists/join-a-data-challenge.md), or [sponsor one](/data-scientists/sponsor-a-data-challenge.md).
### Are there mental models for earning $ in data?
Yes. This section has two other pages which elaborate:
* [The Data Value Creation Loop](/data-scientists/the-data-value-creation-loop.md) lays out the life cycle of data, and how to focus towards high-value use cases.
* [What data is valuable](/data-scientists/data-engineers.md) helps think about pricing data.

The blog post ["How Ocean Can Benefit Data Scientists"](https://blog.oceanprotocol.com/how-ocean-can-benefit-data-scientists-7e502e5f1a5f) elaborates further on the benefits of more data, provenance, and earning.
