In the world of decentralized networks, having a common way to identify resources is crucial for interoperability and openness. That's why the Nostrum Protocol team has developed a new URI scheme called `nostr:` that can be used by anyone to reference their resources on the network. This standardization will make it easier for users to find and interact with each other's resources, regardless of the platform they are using.
