Building on Ocean Protocol – A Developer’s Guide

Ocean Protocol is a decentralized platform built to unlock data for AI and machine learning while ensuring privacy, security, and data sovereignty. It empowers data owners to share their data within a controlled environment using Compute-to-Data, a feature that allows AI models to run computations on data without exposing the data itself. This ensures a balance between data privacy and utility, opening new opportunities for secure data monetization across sectors like finance, healthcare, and AI research.

Ocean’s Architecture and Tokenization

Ocean Protocol leverages blockchain technology to tokenize datasets into datatokens, which can be used to buy and sell data in decentralized marketplaces. This tokenization allows data to be monetized without being directly shared, preserving privacy while enabling secure transactions. Additionally, Ocean integrates data NFTs, offering traceability and ownership features that enhance control over datasets. Developers benefit from the platform’s support for interoperability, which provides tools and libraries that make seamless interaction with smart contracts possible, helping developers build scalable decentralized applications (dApps).

Key Features for Developers

Data Tokens and NFTs

1. Data Tokens and NFTs
   Ocean allows datasets to be turned into datatokens, providing tokenized access that can be bought and sold in decentralized marketplaces. Along with data NFTs, developers can facilitate the trade of data as a digital asset while maintaining ownership, traceability, and verification of datasets. This allows for greater flexibility in managing and monetizing data.
2. Ocean.js and Ocean.py
   Ocean.js is a JavaScript library that simplifies interaction with Ocean Protocol’s smart contracts. It allows developers to publish datasets, manage datatokens, and handle transactions in decentralized marketplaces. For Python developers, Ocean.py offers similar functionality, enabling interaction with the Ocean network for publishing datasets, managing tokens, and executing on-chain transactions. This versatility allows developers to use the language they are most comfortable with while working with Ocean.
3. Compute-to-Data
   Ocean’s Compute-to-Data feature ensures that AI models can perform computations on datasets without exposing the underlying data, thus maintaining privacy. This is ideal for sensitive industries like healthcare, finance, and proprietary research, where data privacy is critical but the utility of data for AI model training remains high.
4. Decentralized Data Marketplaces
   Developers can build decentralized data marketplaces where data owners can publish, sell, and manage their datasets. Powered by Ocean’s smart contracts, these marketplaces enable secure, transparent, and efficient transactions. Notable live examples include Acentrik Market, designed for enterprise needs, and the Ocean Market, which offers a general-purpose decentralized marketplace. These marketplaces foster a thriving data economy, providing liquidity to data that would otherwise be locked away.
5. Token-Gated dApps and REST APIs
   Ocean supports the creation of token-gated decentralized applications (dApps) and REST APIs. This means developers can monetize their dApps or REST APIs by limiting access to those who hold specific tokens. Examples include dApps like Autobot (analytics) and Ocean Waves (music), both of which utilize token-gated access to monetize services. Additionally, token-gated feeds, like Ocean Predictoor (AI prediction feeds), demonstrate how token gating can enhance monetization in various sectors.
6. Enhanced Privacy for User Data
   Rather than storing user profile data on centralized servers, Ocean enables developers to store it on-chain where it is encrypted by the user’s wallet. This on-chain storage allows for just-in-time decryption for the application, reducing exposure to potential security breaches while maintaining functionality. This solution mitigates the risk of centralized server storage, offering a decentralized, privacy-focused alternative for applications managing user data.

Getting Started with Ocean Protocol

Ocean offers various tools for developers at different levels of interaction:

• App Level: Developers can use Ocean templates for building basic dApps quickly.
• Library Level: For more control, developers can use Ocean.js or Ocean.py libraries to manage frontend applications or backend tasks.
• Contract Level: For advanced use, developers can directly interact with Ocean’s smart contracts on Ethereum or other supported chains.

Ocean’s ecosystem also includes important components like:

• Barge: A local test chain for developers to test their applications.
• Ocean Subgraph: A service that retrieves event data from the blockchain for analytics or further processing.
• Ocean CLI: A command-line tool that simplifies managing Ocean services.
• Aquarius: A metadata cache that facilitates fast and secure metadata retrieval.
• Provider: A service for handling access control, ensuring that only authorized users can interact with specific datasets or services.

Use Cases

• Data Monetization: Ocean Protocol allows data owners to tokenize and sell their datasets, providing liquidity to data assets.
• AI Model Training: With Compute-to-Data, developers can train AI models on secure, sensitive data without exposing it, making it useful in privacy-conscious industries like healthcare, finance, and research.
• Private User Data: By encrypting user data on-chain and decrypting it only when needed, Ocean ensures that sensitive information remains secure while providing the flexibility of decentralized applications.
• Decentralized Governance: Ocean enables decentralized governance of data-sharing ecosystems, ensuring full transparency and security in data transactions and decision-making processes.
