I *think* it would require Fediverse resources to be able to have multiple alternative (base) URLs, instead of just one.
"You can find this server on climatejustice.social, or biglongstring.onion, or biglongstring2.i2p."
Am I right, and would that require a change to the protocol?
it would require Fediverse resources to be able to have multiple alternative (base) URLs, instead of just one.By design, ActivityPub actor identifiers are URLs that include the one specific domain name. That's why, while moving followers from one instance to another is possible, it's cumbersome to move your own posts without doing some kludges that don't work well.
There are specifications being worked for non-domain-dependent identifiers, but they are not finished yet, as far as I know.
