💻 Developers

What can you build with Ocean?

1. Token-gated dApps & REST APIs: monetize by making your dApp or its REST API token-gated. Here's how.
2. AI dApps: monetize your AI dApp by token-gating on AI training data, feature vectors, models, or predictions.
3. Data Markets: build a decentralized data market. Here's how
4. Private user profile data: storing user profile data on your centralized server exposes you to liability. Instead, have it on-chain encrypted by the user's wallet, and just-in-time decrypt for the app. Video, slides.

Example live dapps:

• Data Markets: Acentrik Market for enterprises, and Ocean Market for general.
• Token-gated dapps: Autobot for analytics, and Ocean Waves for music.
• Token-gated feeds: Ocean Predictoor for AI prediction feeds

How do developers start using Ocean?

• App level: Use an Ocean Template.
• Library level: Use ocean.js is a library built for the key environment of dApp developers: JavaScript. Import it & use it your frontend or NodeJS.
• Contract level: Call Ocean contracts on Eth mainnet or other chains.
