#Mastodon update: Admins can now easily close registrations with a custom message. In other news, I have closed registrations to mastodon.social for now ensure a quality of service for all existing ones, and to promote other federated nodes.
@_ZN3val@Gargron@cynicalsecurity@chris_martin so here's an idea using just a plain old block chain. When a user signs up, generate a bitcoin address, store the user's requested name in a micro-transaction to that new address and send the private key to the user's client. Then if the user ever wants to change names, generate new address, store new name as metadata on the transaction. Rinse. Repeat.
