hubzilla is a fork of friendica, yes hubzilla shows all likes and dislikes and the names :D

If someone likes my comment then my account relays that activity to the clones to keep them in sync.

the hubzilla network and some other projects have this implemented and it works nicely, a person on hub1 can simply visit hub2 and interact (like comment etc.) since hub2 authenticates user with hub1 using this protocol. I am not a developer of this but it has been tested and used since a number of years.

Here are two resources that document these features:

1. Nomadic Identity: Nomadic identity means true ownership of online identity. With Hubzilla, you don’t have an account on a server, you own an identity that you can take with you across the grid. You can clone a channel across multiple hubs for resilience against network failures or censorship, or you can completely move a channel from one hub to another, taking your data and connections with you.

2. Magic Sign-on https://magicsignon.org/rmagic

Hubzilla has successfully implemented portable identities for a number of years and i am surprised how its unheard of. Coupled with magic sign-on it has some of the craziest features that are much needed in the broader fediverse.
