Ocean SDK QUBO Example — Ocean-sdk Code
Creates a QUBO dictionary and solves it using dimod.
import dimod
from dwave.system import DWaveSampler, EmbeddingComposite
Q = {('x0','x0'):1, ('x1','x1'):1, ('x0','x1'):-1}
bqm = dimod.BinaryQuadraticModel.from_qubo(Q)
sampleset = EmbeddingComposite(DWaveSampler()).sample(bqm, num_reads=15)

Ocean SDK is a Python and JavaScript software development kit designed for building decentralized data marketplaces, enabling secure sharing, monetization, and consumption of data using blockchain technology.
Primary Use Cases
- ▸Publishing and monetizing datasets
- ▸Secure AI model training on private data
- ▸Building decentralized data marketplaces
- ▸Data tokenization for access control
- ▸Enabling compute-to-data workflows
Notable Features
- ▸Data tokenization via ERC-20/ERC-721 standards
- ▸Compute-to-data support
- ▸Access control through smart contracts
- ▸Python and JS SDKs for integration
- ▸Integration with Ethereum and Polygon networks
Origin & Creator
Ocean SDK was developed by the Ocean Protocol Foundation to support decentralized data sharing and monetization, with initial development around 2017-2018.
Industrial Note
Ocean SDK is primarily used for AI, big data marketplaces, decentralized finance analytics, and privacy-preserving computation where data ownership, monetization, and access control are critical.
Quick 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
Learning Path
- ▸Learn blockchain basics and Web3
- ▸Understand ERC-20/ERC-721 tokens
- ▸Familiarize with Ocean SDK Python/JS
- ▸Learn DDO metadata and marketplace publishing
- ▸Implement compute-to-data workflows
Practical Examples
- ▸Publish dataset with ERC-20 token gating
- ▸AI model training via compute-to-data

Comparisons
- ▸Ocean SDK vs traditional data APIs: Ocean is decentralized and tokenized.
- ▸Ocean SDK vs Dataverse: Ocean supports blockchain monetization and compute-to-data.
- ▸Ocean SDK vs IPFS only: Ocean integrates access control and marketplace features.
- ▸Ocean SDK vs Substrate-based marketplaces: Ocean targets EVM chains.
- ▸Ocean SDK vs Filecoin: Filecoin stores data, Ocean enables monetization and computation.
Strengths
- ▸Enables decentralized data marketplaces
- ▸Supports privacy-preserving computation
- ▸Tokenized access and monetization
- ▸Cross-chain compatibility (EVM chains)
- ▸Simplifies integration for developers via SDKs
Limitations

- ▸Requires blockchain knowledge for advanced features
- ▸Some compute-to-data workflows are still experimental
- ▸Mainly focused on EVM-compatible networks
- ▸Smaller developer community than major SDKs
When NOT to Use
- ▸Projects not requiring tokenized data access
- ▸Data stored entirely off-chain without privacy needs
- ▸Non-EVM blockchain platforms
- ▸High-frequency, real-time applications
- ▸Small-scale projects without blockchain integration
