ocean.py

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

With ocean.py, you can:

• Publish data services: downloadable files or compute-to-data. Create an ERC721 data NFT for each service, and ERC20 datatoken for access (1.0 datatokens to access).
• Sell datatokens via for a fixed price. Sell data NFTs.
• Transfer data NFTs & datatokens to another owner, and all other ERC721 & ERC20 actions using web3.py, Brownie, etc.

ocean.py is part of the Ocean Protocol toolset.

This is in beta state. If you run into problems, please open up a new issue.

🏄 Quickstart

Here are flows to try out, from simple to specific detailed variants.

• Simple flow - the essence of Ocean - creating a data NFT & datatoken.
• Publish flow - a dataset is published.
• Consume flow - a published dataset is consumed (downloaded).
• Marketplace flow - a data asset is posted for sale at fixed rate, then purchased.
• Dispenser flow - here, a datatoken dispenser is created and datatokens are dispensed for free.

Remote flows

• Get test MATIC - from Mumbai network
• Simple remote flow - like the simple flow, but using remote services.
• Compute-to-data flow - uses C2D to build an AI model.

More types of data assets

• REST API flow - publish & consume REST API-style URIs, showing Binance ETH price feed
• GraphQL flow - publish & consume GraphQL-style URIs
• On-chain data flow - publish & consume on-chain data

Key-value flows

• Key-value database - use data NFTs to store arbitrary key-value pairs on-chain.
• Profile NFTs - enable "login with Web3" where Dapp can access private user profile data.

Data Challenge flows

• Predict-eth repo - data challanges with $ to predict future ETH price.

Learn more

• Get test OCEAN - from Goerli
• Understand config parameters - envvars vs files
