@Ferminho @maegul This proposal describes a very simple marketplace, and some things were intentionally left out. However, it is based on Valueflows system which can be used to describe many different economic processes, including planning, production and transportation:

So developers may use object types and properties defined there if they want to build something more complicated. And social interactions can be represented as standard ActivityPub activities. I think Valueflows and ActivityPub nicely complement each other.

@Emperor @MostlyLazy If the server doesn’t process payments it should not cause admin a headache in most (?) jurisdictions.
Alternatively, one could focus on grey markets.

By the way, Bitejo was planning to add federation, although now the future of the project is a bit uncertain. It might be added to Bitejo fork, as I suggested in this CCS: https://repo.getmonero.org/monero-project/ccs-proposals/-/merge_requests/395#note_21836

@cyclohexane Today Instances also work as identity providers, but in the future identities are likely to become portable, and the only service provided by instances will be moderation.

@0x1C3B00DA There is a discussion of a similar proposal on SocialHub forum: https://socialhub.activitypub.rocks/t/suggestion-a-custom-url-scheme-handler-as-a-streamlined-ux-for-cross-instance-interactions-on-the-web/504
