More ways aren't bad. But those ways should have turns and roundabouts and small footpaths and bridges and maps.
What good is a way that only connects a couple places, but isn't accessible from the rest of the world?
Yes.
That’s why “app builders” like Bonfire and Emissary are so interesting for this space.
We enable the “long tail” of technology adoption, and make it possible for tiny communities to launch highly customized Fediverse apps with very low effort. Small paths, many branches.
AtlasMaps.org (for instance) took me about six weeks start to finish. Other community-specific servers will launch even easier.

@benpate @bonfire @swf @sovtechfund I'll read up on what ActivityPub does, but MLS seems like a pretty good start and makes me fear it somewhat less.
Still, we need well thought out interoperability in our FOSS communities. We're more and stronger together.
Jump on the GitHub issues. We’d love to talk.
GitHub - swicg/activitypub-e2ee: Coordination of work on end-to-end encryption with ActivityPub
Coordination of work on end-to-end encryption with ActivityPub - swicg/activitypub-e2ee

And, I’m happy to walk you through how I’m trying to approach it. We have a tight timeline, but more eyes is still better at this point.

Things I wonder:
- Where will the keys be stored?
- Where will the code come from?I hope none of those will be answered with "browser".
Also, signing in to all messengers in one tool is nice, but what we need is to be able to communicate directly.
It's nice if I can talk to Johne Doe on IRC and Jane Doe on AOL, but what if I want to have a group chat? Yeah.
Keys will be encrypted on the browser, locked with a separate password that’s not shared with the server.
There are some other synchronization issues we’re going to work out, but not before our first sets of code are due.
There’s more here than I can cover in 500char toots. But I’d be happy to chat some time to hear your thoughts

Big news for the #Fediverse! End-to-end encryption is coming to #ActivityPub.
@swf with support from @sovtechfund is coordinating two interoperable implementations.
Bonfire is proud to be one of these first two projects, alongside #Emissary by @benpate
We think #E2EE should simply be the default for any private communications, and we’re especially thrilled to bring private, trusted collaboration to the fediverse.

@benpate @bonfire @swf @sovtechfund Another thought before I'll catch up on sleep:
If the code that handles the key material comes from the webserver, that does not stop a government that's hostile from ordering the website owner to run malicious code that'll also encrypt messages for their people... That's what I worry mainly about in terms of security.

I am woefully ignorant here. Spare a link for this poor lad?

Yes. There has to be trust somewhere along the path.
You could host your own server, but you’d still have to trust the developers to not install a back door. Or a supply chain hack. Or…

One goal is to make this an interoperable standard, so that you could make your own client app, then use your ActivityPub server as only a dumb pipe.
I think that would instill trust.
More in the AM.

@bonfire @swf @sovtechfund @benpate Ooof, just another instant messenger..?
We've already had XMPP since the 90s... and since then it's become pretty reliable.
i hope there'll at least be interoperability. I'm so tired of new ways to communicate that are not interoperable with what's already there.

There is room for more instant messagers:

@benpate @bonfire @swf @sovtechfund The weak point will be wherever you host the webserver. If a court or corrupt official orders them to install something bad, perhaps a backdoor, that is an issue.

Yes, agreed. I know I said this before, but can't find it:
One important goal is to make a solid, consistent client-side API - something like what C2S was intended to be. That would enable interchangeable clients for mobile/desktop/etc that work with any server.. and greatly increase the trust factor.
I'm only good at making web apps, so that's what Emissary's first client will be. But there will be space for others to build on top of this work.

I feel like this is the right time to mention https://xkcd.com/927/
You're very right here. There are tons of IM services. "Why introduce another one?" is a reasonable question
But I don't see it in those terms because we're not creating a new network. This is adding features to network we already have
I'll still use Signal. And Apple Messages
And I'd also like to talk privately with people here, as well. There is room for both.

Our initial clients will be built in JavaScript, so you’d need to enable JS on your browser to use it (for now)
And, it will require special features on your server, so this won’t work on Mastodon (for now)
Download the road, things will change. We’re defining a standard API that anyone can build in. So hopefully someone can built installable clients (iOS, Android, desktop) that work separate from your browser.
