Yep, the concept of decentralised identities has been around for a while now. Also the focus of nostr:npub1sg6plzptd64u62a878hep2kev88swjh3tw00gjsfl8f237lmu63q0uf63m company TBD and the driving idea behind “Web5”. Our identities are already spread around numerous centralised databases run by third-parties, which when you consider it, is an absolute privacy nightmare and a complete loss of control on an individual level. Our identities are something we should control and we should be able to decide which services we access and prevent them from sharing our data. And equally be able to deny those services access later.

Why solve it with Bitcoin?
Mainly because it is the most secure censorship-resistant, open and decentralised blockchain to anchor DIDs too. A “timechain” that records our identity changes in an immutable fashion that will likely outlive any centralised company or newly created blockchain starting from scratch. That all said, the NOSTR model could probably be used too.
BTW, I’m in no way saying it’s the right thing to do.
