But do we need some kind of SSO layer with DID verification? All I need to prove my identity anywhere, technically, is my private+public keypair. As long as I hold on to this keypair, distribute it between apps/computers, back it up, I could log in anywhere on a federated platform and use it.

I hope we’re going to see key-based decentralized identity on ActivityPub at some point… Having accounts tied to instances is just not very robust or scalable.

“Practical Engineering” is a fantastic channel. I especially appreciate all the infrastructure failure analysis videos he has done. It let me (a non civil engineer) understand why certain infrastructure disasters like collapses, power outages, or dam breaches were able to occur.
