Ocean Protocol (OCEAN) is used in several ways to facilitate the decentralized exchange and monetization of data:

1. Tokenization of Data: Data providers tokenize their data using the OCEAN token, which represents a digital representation of the data. This token can then be traded on Ocean Protocol's decentralized marketplace.

2. Staking and Governance: OCEAN tokens are used for staking on data for curation and governance purposes. This includes community voting and decision-making processes.

3. Transaction Fees: OCEAN tokens are used to pay transaction fees on the platform. These fees support the ongoing development of Ocean technology and fund the buy-and-burn process of OCEAN tokens, which reduces the token supply and increases demand.

4. Data Marketplace: The OCEAN token serves as the medium of exchange on Ocean Protocol's data marketplace. Data providers can sell data access to interested parties, and data consumers can purchase data using OCEAN tokens.

5. Compute-to-Data: Ocean Protocol allows users to remotely leverage machine learning and AI without relocating their assets, enabling novel revenue streams. This is achieved through the use of Data NFTs and Datatokens, which provide tailored access to data environments and control access to information.

6. Node Operators: Node operators play a crucial role in verifying and executing transactions on the Ocean Protocol network. They are rewarded with OCEAN tokens for their work, ensuring the network's proper functioning.

Overall, the OCEAN token is the native utility token of Ocean Protocol, facilitating the secure, transparent, and private exchange of data and data-based services.
