boosting is an event kind 6, where the tag is the id of the boosted event. so that means, the content of your note doesn't get reposted, but it does show up to other users of the paid relay and has a field that says what relay to find the boosted note on.
Discussion
There are two different ways people are doing boosts. Some kind=6 events have the original event json encoded as the content.
oh, nice, yeah that'd be handy.. tho i guess you have to trust that the booster didn't just edit your message lol!
It contains the entire signed original event. Can't be edited.
I'm not saying it's a good idea. fiatjaf is against kind=6 entirely. It's not NIPped. I have no opinion myself.
ah, makes sense yeah i was wondering if it'd have the signature... cool. The nip for it is NIP-18 btw.. (reposts).
and looks like NIP-10 absorbed changes to reflect what clients currently are doing, it's called a mention marker. Neat!
In the wild we have 3 things: the mention marker in kind-1, the kind-6 with a content like "# [ 0 ]" and a tag with the mention marker, and a kind-6 with the json-encoded event in the body. I added support for that last one to gossip recently because it was less than 10 minutes of work. The first one was already supported. The middle one doesn't work on gossip right now, but I should fix that.
ah, i read further about nip-18, i guess it's kindof a dead spec.. damus and etc just quote the content like you were saying..
Do you know if that’s what Damus is doing when you use the “repost” button? A few weeks ago it was called boost and then it got renamed.
after reading some more, it sounds like damus is posting the quoted content into the event.. so that means, the content does make it to the paid relay. you can read more of the discussion here if you want:
