## Share and Re-Use via CID

Nodes are optimized for re-usability and interoperability. Each component published with DeSci Nodes has its unique [content identifier (CID)](https://docs.desci.com/technical-background/persistent-identifiers-101#solving-content-drift). This identifier is, as the name says, based on the component's content -- and therefore unique to this component (and its exact duplicates). You can use CIDs to access your components through other applications connected to the IPFS network, like compute over data with [Bacalhau](https://www.bacalhau.org/).

Grab any component's CID via [#node-drive](https://docs.desci.com/general-user-overview#node-drive "mention"). Navigate to the component of interest and hit <img src="https://3561840309-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FMYxRLCpbB6u9NiTwuU16%2Fuploads%2FuhbbwIEXUZRb0GgoWDA3%2Fimage.png?alt=media&#x26;token=9225ab0a-0daf-4e19-abce-2e6fe43bbab7" alt="" data-size="line">. Click on **Copy Link** to save the CID to your clipboard.
