What is the DID and for what is useful?
DID stands for Decentralized Identifier. It's a W3C standard for creating unique identifiers for digital assets.
In Nevermined all the different assets (agents, payment plans, datasets, etc) are identified by a DID. This DID is unique and can be resolved to get more information about the asset.
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:{identifier_of_the_asset}
For example:
did:nv:dbf7a307b11eb5b29ef4564b6eb6b199ee5e724fa4e24622ed143b549d41b5e6
Where can I find the DID?
You can find the DID of each asset in the Nevermined App. For example, in the Agent details page:
a. In the Additional information tab of the asset details page b. In the URL of the asset details page
If I'm a Builder why this is important?
The DID is the way to identify your asset in the Nevermined network. When you want to interact with Nevermined programatically via the Payment Libraries, knowing the DID of your asset is important to be able to interact with it.
