Python library to privately & securely publish, exchange, and consume data.

With ocean.py, you can:

• Publish data services: downloadable files or compute-to-data. Ocean creates a new ERC20 datatoken for each dataset / data service.
• Mint datatokens for the service
• Sell datatokens via an OCEAN-datatoken Balancer pool (for auto price discovery), or for a fixed price
• Stake OCEAN on datatoken pools
• Consume datatokens, to access the service
• Transfer datatokens to another owner, and all other ERC20 actions using web3.py etc.

ocean.py is part of the Ocean Protocol toolset.

This is in beta state and you can expect running into problems. If you run into them, please open up a new issue.

#Install the ocean.py library. Install wheel first to avoid errors.
pip install wheel
pip install ocean-lib

⚠️ For Mac users, if you encounter an issue with "Unsupported Architecture", see this issue for an explanation and run the installation command with ARCHFLAGS set, like so:

ARCHFLAGS="-arch x86_64" pip install ocean-lib

This stripped-down flow shows the essence of Ocean: simply creating a datatoken.

Go to simple flow

In this flow, a data asset is posted for sale in a marketplace, and purchased. It includes metadata and a datatoken pool.

Go to marketplace flow

This flow uses Ocean Compute-to-Data (c2d) to compute results from a dataset that never leaves the premises.

Go to c2d flow

• Get test OCEAN - from rinkeby
• Understand config parameters - envvars vs files
• Learn about off-chain services - Ocean Provider for data services, Aquarius metadata store
• Learn about wallets - on generating, storing, and accessing private keys
• Get an overview of ocean.py - key modules and functions

Go to developers flow if you want to further develop ocean.py.
