What is the DID and what is it useful for?
DID stands for Decentralized Identifier. It's a W3C standard for creating unique identifiers for digital assets.
In Nevermined, all the different Agents are identified by a DID. This DID is unique and can be resolved to get more information about the Agent.
You can find further information about the DID standard in the W3C DID specification and how this is used on the Nevermined Protocol here.
The DID in Nevermined has the following format:
did:nv:<unique-identifier-of-the-agent>
For example:
did:nv:dbf7a307b11eb5b29ef4564b6eb6b199ee5e724fa4e24622ed143b549d41b5e6
Where can I find the DID?
You can find the DID of each Agent in the Nevermined App. For example, in the Agent details page:
a. In the Additional information tab of the Agent details page b. In the URL of the Agent details page
If I'm a Builder, why is this important?
The DID is the way to identify your Agent in the Nevermined network. When you want to interact with Nevermined programmatically via the Payment Libraries, knowing the DID of your Agent is important to be able to interact with it.
