Explain
Ocean SDK provides tools to publish, discover, and consume datasets on-chain or off-chain with privacy-preserving techniques.
It integrates with Ethereum, Polygon, and other EVM-compatible networks for tokenized data access.
Supports AI/ML workflows by allowing compute-to-data and data marketplace interactions.
Includes libraries, smart contracts, and APIs for data access control.
Used in DeFi, data marketplaces, and AI-data monetization platforms.
Core Features
Ocean Market smart contracts
DDO (Decentralized Data Object) metadata format
Compute-to-data module
Access management via tokens
Event tracking for dataset consumption
Basic Concepts Overview
DDO (Decentralized Data Object) defines dataset metadata
ERC-20 or ERC-721 tokens control dataset access
Compute-to-data allows private computation on data
Market contract handles publishing, buying, and consuming data
SDK exposes APIs for dataset lifecycle management
