@big_louse Thanks for looking at repos!
>So on the server side, the clearnet instances would just have to enable tor etc. to talk to the onion sites?
Yes. Mitra supports this federation mode out of the box. Users of other software can use additional proxy server which will route requests. For example you can make Pleroma work on both networks by connecting it to Privoxy and adding these two lines to your Privoxy config:
forward / . forward-socks5t .onion 127.0.0.1:9050 .Maybe this trick also works with Mastodon, I don't know.
>Would I be able to see/interact with that .onion post *without* having tor enabled server side? Even if I federate with an instance that boosts it?
No, your server won't be able to access the boosted post. To make darknet posts accessible to the whole Fediverse we need a bridge.
>( i'll spare you my anti ETH rant)
I probably agree with what you had in mind.
Ethereum integration is not actively developed anymore, and will likely be removed in the future.
