The Four Layers of the Internet’s Identity Stack 1️⃣ URN – Uniform Resource Name → What it is. A persistent name for a thing, independent of where it lives. 2️⃣ URL – Uniform Resource Locator → Where it is. The address that points to its current home on the network. 3️⃣ URI – Uniform Resource Identifier → How it’s identified. A standardized syntax that unites names and locations. 4️⃣ URB – Uniform Resource Bus → How it connects. The next evolution — a universal bus for messages, payments, and trust. From naming and locating to connecting and transacting. #URB #InternetEvolution #Nostr #SovereignWeb
