@benpate You mean they are sent in an encrypted envelope? In that case I would use EmojiReact, the canonical variant. Like with content is a hack for compatibility with Mastodon, but if activities are encrypted it shouldn't be necessary.

@ropoko HTTP signatures and WebFinger are must have.
This guide might be useful:

@phnt @feld @benpate Would you accept a FEP? https://codeberg.org/fediverse/fep/src/branch/main/fep/c0e0/fep-c0e0.md

silverpill@silverpill@mitra.social (2026-04-15 02:23:14)
@feld @phnt @benpate Fair point. I usually imagine a network of small instances where spying admins are not a problem, but Mastodon is a different world.

@feld @phnt @benpate It doesn't seem to be an issue in the Matrix ecosystem where people often self host web clients.

@benpate As somebody who also thought about E2EE (MLS was my suggestion), I can confidently say that SWF spec didn't add much to the discussion. That's not surprising, because to do that one needs to actually start writing code.

@deutrino @benpate Of course not. The first thing their new CEO did in his introduction post was to memory-hole a bunch of projects.

@phnt @benpate These censorship/moderation tools are likely a part of their mainstreaming strategy. They want big orgs, including governments, to host Mastodon instances. The same playbook is used by Matrix.
So I don't think it's a threat, just another brick in the wall separating Mastoverse and the rest of the network.
Reply to @benpate@mastodon.social
silverpill@silverpill@mitra.social (2026-04-15 00:30:00)
@benpate I wouldn't count on that.
In the announcement Mastodon team credits SWF for work on E2EE, not the people doing actual research. That's part of the deal.

@phnt @mirq I think the best option is local-first with mirroring to several hosts on different networks (Tor and clearnet, for example).
silverpill@silverpill@mitra.social (2026-04-14 20:35:11)
Recent advancements in quantum computing pose a threat to systems where identity is derived from a public key, such as blockchains:
https://blog.succinct.xyz/google-quantum-ai-paper-crypto/
FEP-ef61 currently uses did:key identities, which are also derived from public keys. They are supposed to be permanent, so to avoid costly migrations in the future we need to offer an option compatible with post-quantum signatures.
I opened an issue about adding such option to did:key specification: https://github.com/w3c-ccg/did-key-spec/issues/74
The downside of post-quantum signatures, however, is that they require very long keys. This means object URIs are also going to be very long.
did:webvh may be a good alternative to did:key if URI length becomes a problem.

@japananon flohmarkt doesn't provide an outbox, which is necessary for loading latest posts (but maybe they will add it? https://codeberg.org/flohmarkt/flohmarkt/issues/983).
>even appeared at the top of my Home feed as though it was newly fetched
This is expected, because Mitra displays posts in the order they were discovered.
Are you thinking about hosting a flohmarkt instance?

silverpill@silverpill@mitra.social (2026-04-14 02:03:13)
@fox I was considering it, but then your git instance went offline and the image was not up to date.
I think it can be added now.

silverpill@silverpill@mitra.social (2026-04-14 01:31:27)
@phnt @fox I don't use docker in production, so I am happy that others take care of images.
Haven't decided on CI yet. My plan was to move to my own self-hosted Forgejo instance once forge federation is implemented, and start building advanced infrastructure there. But the work on federation is progressing very slowly.

@japananon When I search for https://kleinanzeigen.bonn.digital/~bonndigital/48a0e2b7-f0d0-421b-9190-cc15306be6a3 it appears as a post. Listings from followed users should also show up in the home timeline.
These posts don't get any special treatment, however. It is possible to display some additional info thanks to FEP-0837, like price and available quantity, but I haven't done that yet.

Just for the record, I do not agree with the premises of that article.
Fediverse doesn't gradually diverge from the ActivityPub spec and software development doesn't look like you describe.
Overall, it looks like an attempt to discredit FEP process by painting it as ineffective and unsustainable, in favor of... I am not entirely sure, GitHub repo and a non-profit?
silverpill@silverpill@mitra.social (2026-04-11 23:50:57)
flohmarkt now implements FEP-0837: Federated Marketplace!
They add Proposal as an attachment to Note. Here's an example:
https://kleinanzeigen.bonn.digital/~bonndigital/48a0e2b7-f0d0-421b-9190-cc15306be6a3
I think Proposal properties could be added directly to Note to make the structure simpler. But an attachment is fine too.

@Profpatsch A lot of effort is being put into reducing implementation complexity - it is just not very visible. Libraries, testing tools, documentation (such as the guide that I mentioned during our previous conversation).
However, the complexity is unavoidable in a decentralized network. A standardized representation of a quote (FEP-e232) was proposed long time ago. It was easy to implement, versatile (FEP-e232 could be used to build any kind of link, not just a quote), and it was supported by a significant number of fediverse projects. Then Mastodon developers decided to invent a different kind of quote, with all the unnecessary complexity that you described. But I'd rather deal with this complexity than have some centralized standards org telling me what to do.
Another issue is disinformation -- and that is really weird, and unique to Fediverse. You probably heard that JSON-LD is required, but that is not true. The spec doesn't require it. Only a few Fediverse projects actually use JSON-LD, and as a developer you don't need to worry about it -- adding "@context": "https://www.w3.org/ns/activitystreams" to your JSON makes your software compatible with >99% of Fediverse instances, and even that is necessary because Mastodon has a bug. Unlike the problem of competing standards, this problem can be solved by writing better documentation.

The Fediverse deserves a dumb graphical client
I love the Fediverse. I have been on it for years, and it remains the only social network where I actually enjoy spending time. No algorithmic feed pushing outrage, no dark patterns, no surveillance capitalism. Just people talking to each other over an open protocol.
But every time I wanted to recommend it to someone, I ran into the same wall: the clients are heavy. Mastodon's web interface ships megabytes of JavaScript. Elk, Phanpy, Ivory, beautiful apps, but they require a modern browser, a fast connection, and a device manufactured in the last five years ...

This update includes several minor changes and clarifications. Mitra Mini was added to the implementation list. I also added a sequence diagram for actor registration process:

I implemented delivery queue in Mitra Mini. This means it can work offline: activities will be published to the fediverse once a connection to the gateway is established.

@julian Thanks!
Mitra supports subdomain.domain.tld -> domain.tld setups, but not setups with two different subdomains like @canary@correct.webfinger-canary.fietkau.software of yours.
I'll fix that in the next release.
