Another product from DeSci Labs is our dPID layer - . DeSci Nodes is built around the dPIDs which are persistent identifiers that stick to the root of the Nodes in a sustainable manner. 

\
You can get the link to the dPID of the Node, to share but also for your own reference, as follows.

## Share via Persistent Identifier

When you publish your Node, it will automatically receive a [decentralized persistent identifier (dPID)](/technical-background/persistent-identifiers-101.md). You can share your work with others by forwarding this permanent link to your work. Others can cite your work using this PID. 

dPID feel and function like [simple filepaths](/technical-background/open-state-repository/pid.md). This makes it super simple to share and granularly cite individual components. 

You can access your Node's dPID from [General user overview](/general-user-overview.md#node-drive). Click on **Cite** for whichever component you want to share and simply copy the dPID. The root dPID always looks like this: `dpid.org/{some number}`. This root dPID always points to the latest version of the full Node. But with dPID, you can get specific: Want to share a CSV from Dataset 5 from Version 2 of your Node? Sure. Just select the component in [General user overview](/general-user-overview.md#node-drive) and copy its dPID -- or type out the dPID yourself. It's always `dpid.org / {Your Node's root PID} / {version number} /{component type}/ {component name}`.
