Not Paul, but DID is a stable ID over time, whereas dns is not. This lets you change your handle without the network losing track of who you are. I was @steveklabnik.bsky.social before I was @steveklabnik.com, and when I made the switch, all of my previous stuff was still there. This is a fun party trick in some sense, but also a real meaningful feature in another. If I ever decide to move from steveklabnik.com to steve.klabnik.com, a thing I have been considering for a few years, my stuff on @proto/Bluesky will be one of the only services that doesn't have the issue that's kept me from pulling the trigger: updating the entire world that that's where I am now.

Yes! And if this were not the case then account portability between PDS hosts would be really challenging. Same logic as keeping your phone number when you switch cell carriers

DIDs are stable only in the context of a specific 'verifiable data registry' as the spec puts it. https://www.w3.org/TR/did-core/#dfn-verifiable-data-registry https://www.w3.org/TR/did-core/#dfn-verifiable-data-registry DIDs delegate trust and authority to a data registry, in exactly the same way that DNS delegates trust and authority to ~ICANN. The system model is exactly the same. The difference is only in the properties of the authoritative entity.

  That's a good point: I was speaking in a more social manner. Because domains are human-readable, they tend to be used for humans. Bluesky could have chosen to just use domains, but I personally prefer that we have the additional layer of indirection. Plus like, you have the ability (at the low level, not really exposed in the UI in any meaningful way) to be multiple people: I can associate multiple domains with my DID. That said, you're not wrong that a registry is a registry.

    Yeah, definitely not suggesting domains are a better form of identity!
