The European Commission has funded an open source project to create a Gateway between the ActivityPub and XMPP PubSub Protocols, and E2EE on PubSub

From goffi: "it's my pleasure to announce that an ActivityPub <=> XMPP gateway doubled with Pubsub end-to-end encryption project has been selected for a grant by NLNet/NGI0 Discovery Fund (with financial support from European Commission's Next Generation Internet programme)".
The XMPP <=> ActivityPub gateway will join two major open and decentralised protocols. In practice it will be a XMPP server component (usable with any server), and implement the ActivityPub server to server protocol (or "Federation Protocol"). On XMPP side, it will be mostly a Pubsub service (with some extra, like private messages converted to XMPP message stanza).
XMPP blogging (XEP-0277: Microblogging over XMPP) will be used, and thus any client supporting it will have access to ActivityPub publications (Libervia and Movim for instance). For features present in ActivityPub and not yet in XMPP, it is planned to propose protoXEPs (i.e. proposition of XMPP extensions), to implement them. Events will also be part of the project, with a compatibility between Mobilizon and Libervia expected, and a protoXEP to have this standardised on XMPP side.
This is quite exiting, as it will extend both networks, and boost projects integrating blogging and XMPP chat.
