Ocean Node handles network communication through libp2p, supports secure data handling with Trusted Execution Environments (TEE) and Multi-Party Computation (MPC), and enables flexible compute-to-data operations.  Ocean Node handles network communication through libp2p, supports secure data handling with Trusted Execution Environments (TEE) and Multi-Party Computation (MPC), and enables flexible compute-to-data operations. 
The functions of Ocean node include:
* It is crucial in handling the asset downloads, it streams the purchased data directly to the buyer.
* It conducts the permission an access checks during the consume flow. 
* The Node handles [DDO](https://docs.oceanprotocol.com/developers/ddo-specification) (Decentralized Data Object) encryption.
* It establishes communication with the operator-service for initiating Compute-to-Data jobs.
* It provides a metadata cache, enhancing search efficiency by caching on-chain data into a Typesense database. This enables faster and more efficient data discovery.
* It supports multiple chains.
