UPDATE: ActivityPub over Syncthing actually works. I am exchanging activities with another Mitra Mini user.

2026-05-02 17:00:31 UTC

Fediverse & P2P
Nomadic identity is a nice feature, but FEP-ef61: Portable Objects is not limited to that. The intention was always to allow peer to peer communication without servers. This is why the protocol was designed to be transport-agnostic: you can use fediverse servers to deliver activities, but you can also use emails, torrents or USB sticks.
To explore these possibilities, I added a simple P2P synchronization mode to Mitra Mini, which allows clients to exchange activities via a shared directory. This doesn't mean that clients should run on the same machine. Syncthing is a tool for P2P file synchronization that can be used to share a directory between multiple machines, and it should work well for our use case.
The P2P mode is available in Mitra Mini v0.4.0. You can use a pre-compiled binary, which is now self-contained and includes the mitra-web frontend. See installation instructions in the readme. To enable P2P mode, add the following block to your configuration file:
[federation]
p2p_shared_outbox = "/path/to/shared/directory"
Registering on a web gateway is not necessary when working in P2P mode, but you need to specify it in the config, because a lot of legacy code still depends on that.
If you'd like to connect, DM me your Syncthing device ID (it can be used in a Whonix VM to prevent IP address leaks).

Announcing Mitra Mini v0.1.0
Mitra Mini is an ActivityPub client that implements nomadic identity. It has become stable enough that I decided to cut the first release.
The basic features have been implemented: posts, reposts, likes. For more information, check the project's readme:
https://codeberg.org/silverpill/minimitra
It all started nearly four years ago with a vague idea that linking cryptographic keys to #ActivityPub actors could unlock decentralized identity in Fediverse. Eventually, the solution was discovered, and implemented by several projects, but these implementations were servers, not clients. Now there is finally a client, and the design has been proven to work well.

It's the question of why so many open source tools get built by startup teams in the first place.
Not that many. Their developers are the loudest, but in most cases a not-for-sale alternative exists, and often that alternative is of higher quality.
My dependency tree is almost corpo- and startup-free (the biggest problem is probably TypeScript).

I have a couple of comments regarding the spec https://codeberg.org/portafed/portafed/src/branch/main/portafed-spec/spec.md
It contains a comparison with FEP-ef61, but it is not quite correct:
- FEP-ef61 identity is not actor-rooted. The closest equivalent of FEP-ef61 identity in normal ActivityPub is a server with a domain name. A single FEP-ef61 authority can manage multiple actor documents.
- FEP-ef61 does not lack a migration flow. Strictly speaking, it doesn't need one, because data is not attached to a server and can be continuously synchronized between multiple servers. But a more familiar migration flow is also possible via outbox export-import.

There have also been rumblings of implementing Zot/Nomad’s nomadic identities, although that effort seems to have stalled out. Finally, some platforms like Streams/Hubzilla (Nomad & Zot respectively) offer limited user account ownership, bridging internally to ActivityPub. However, if a server went down, the user would retain their Nomad/Zot following while losing their ActivityPub followers/following.
It didn't stall. Streams and its successor Forte support ActivityPub-native nomadic identities.
There are other implementers too: https://codeberg.org/ap-next/ap-next/src/branch/main/nomadpub.md

The Mastodon API is open source, but it is not an open standard. It is designed, maintained, and changed by one project, without input from the rest of the ecosystem.
Not without. The design of this API is shaped by the needs Mastodon users. Sometimes PRs are submitted by developers of 3rd party clients and by developers of other servers. Independent implementers of Mastodon API often extend it, and copy each other's extensions, there is even a discussion about Mastodon API Enhancement Proposals (similar to FEPs).
So I think that by now it is very much an open standard.
ActivityPub API may have W3C's stamp or approval, but that doesn't mean anything if nobody uses it.
P.S. Does you blog not federate anymore?

@nprofile…2gus Publishing process doesn't change much. A generic server should deliver activities to actors specified in to and cc fields. It should keep track of collections, such as followers collection, and "expand" them before delivery. This part is not different from the regular ActivityPub.
I think ID assignment should also work the same. In the FEP I proposed Add activity without object as a special activity for creating collections, but now I see that it will not work if IDs are minted by a server (no FEP-ae97).
Perhaps it should be a Create, after all, as @nprofile…u8dh described in an adjacent comment. I was hesitant to use Create because this is a problem for FEP-ae97 clients (not a big one though).

2026-02-27 22:02:28 UTC

@nprofile…2gus Let's assume that my client is a music player. It publishes a Listen activity where object is an Audio. This activity should increase playCount on the Audio object.
One way to support this on the server side is to teach it about Listen, Audio and how to update playCount. This is how most existing servers are built.
But a server described in my FEP would work differently:
- It doesn't know anything about Listen, Audio or playCount.
- Upon receiving Listen, it will recognize it as an activity, and embedded Audio as an object.
- Since this is not a CRUD operation, it will not check permissions.
- If Listen activity has a result property, the server will process that activity as well.
- If result is an Update activity, the server will recognize it as a CRUD operation and will check permissions: Update.actor and Audio.attributedTo must be the same.
- The server will save both activities, Listen and Update.
- Then it will deliver them to intended recipients (to and cc).
Effects are client's responsibility now, it must provide an Update activity if it wants to update playCount. There are other requirements too, for example all objects should have an attributedTo property, which is needed for permission checks.
But in this setup a single server can work with any kind of client.

With quotes we were almost successful. The initial version of Mastodon's consent-respecting quotes was based on FEP-e232, but later they decided to introduce a new property.
Now there's FEP-521a (public keys), which they expressed interest in implementing.
Even with Mastodon, it's worth trying.

What happens when you send a "Offer" message to an actor on Mastodon?
The behavior of Offer activity is not described in ActivityPub, so Mastodon is not required to support it. Curiously, ActivityPub mentions Offer when it talks about the side effects of Accept:
The side effect of receiving this in an inbox is determined by the type of the object received, and it is possible to accept types not described in this document (for example, an Offer).
...This statement is not compatible with the idea of a generic server.
Can I create a group actor on Mastodon?
I don't know. But it can create Service actors, I guess it can be easily patched to allow creation of Group actors too.
Can I use this actor to boost other actor's posts and have it visible on a Lemmy client?
I think FEP-1b12 Announce is not compatible with ActivityPub. It has different side effects, doesn't update shares collection.
How can a Mastodon client ask the server to get a collection of all images with an specific tag?
Maybe something like /api/v1/timelines/tag/{tag}?only_media=true ?

@nprofile…834j It looks simple on the surface, but in reality it is much more complicated than a non-generic server. In addition to activity transfer, generic server needs to maintain collections. First of all, a followers collection, which is often used as a delivery target. Then likes, shares etc. It needs to enforce permissions, to prevent actors on the same server from deleting each other posts.
This is doable if you only care about activities defined in ActivityPub. But then you want to introduce context collection. And then 50 other extensions. How to do that without special-casing every one of them?
This is where duck typing (FEP-2277) and unified security model (FEP-fe34) become really handy. No matter what the client sends, you can figure out what it is (an object, an actor, or a collection), and enforce permissions.

@nprofile…d8rs Mastodon supports all standard activities and has a wide variety of clients. I don't find softwares with similar capabilities impressive, although I respect your work (the only ActivityPub server-client project that is not a vaporware).
I doubt that language choice makes much difference, and Rust is not a dynamically typed language anyway. The difficulty you might be facing is likely due to JSON-LD.
The thanks was for your input with regards to collection management.

Recently, there was a discussion about generic #ActivityPub servers. Several people claimed that they were working on one, but it turned out that their "generic" servers only support activities defined in the ActivityPub specification. Such a server shouldn't be called generic. It is not difficult to build, neither it is an interesting concept because competing protocols (e.g. Nostr) already offer much more.
I've been writing a #FEP that describes how to build a real generic server. It is not finished yet, but I feel like now is a good time to publish it:
FEP-fc48: Generic ActivityPub server
This kind of server:
- Can process any object type, and can process non-standard activities like EmojiReact.
- Compatible with FEP-ae97 clients.
- Does not require JSON-LD.
I attempted to implement it when I was researching security properties of FEP-ae97 API: https://codeberg.org/silverpill/fep-ae97-server. Back then I didn't know what to do with side effects, but now I think that we can simply force clients to specify them.
Special thanks to @nprofile…d8rs and @nprofile…u8dh for their input.

@nprofile…ut88 It is a good plan!
FEP-ef61 is still DRAFT and includes a warning that the URI scheme may change to ap+ef61.
Right, all of this is very unstable and may change in the future. In order to be more confident with the spec, I want to build:
- A fully featured FEP-ae97 client (WIP: https://codeberg.org/silverpill/minimitra)
- A generic FEP-ae97 server (this is only an idea: https://codeberg.org/silverpill/feps/src/branch/main/fc48/fep-fc48.md).
Gateway forwarding trust. When forwarding inbox/outbox activities to other gateways, which servers should be trusted and how should that trust be established? FEP-ef61 says unsecured collections may only be accepted from servers in the actor's gateways array, but the details of how a gateway authenticates itself to another gateway are not fully specified.
Could you clarify what you mean by authenticating itself to another gateway?
When an application (client or server) fetches a portable collection from a server that is listed in actor's gateways array, it may skip proof verification. This applies to collections like inbox or outbox.
If a portable collection is fetched from some other server, the proof is required.

What backlinks?

1. I don't care much about the "official" version of AP. It is outdated and increasingly irrelevant, most of the real development happens elsewhere.
2. Interledger is a part of Ripple/XRP cryptocurrency project, which is a scammy crypto company.
Please don't spread FUD. Especially when it's so obviously counterproductive. Seems like maybe you need to touch grass a bit more often
Oh my. Counterproductive to what? All you do here is talking about things you know nothing about and trying to insult me. You're pathetic.

@nprofile…ut88 It's a good idea. However, I'd like to note that w3id.org/fep/ permalinks are not canonical, they were proposed in FEP-888d but have never become "official".

@nprofile…20nh How much it is tied to Mastodon? Is it possible to use Fediway with other servers?

@nprofile…ks9l I am pretty sure that nice things are within reach.
Fediverse-ActivityPub already significantly diverges from W3C-ActivityPub. I think eventually they will become completely different protocols, that just requires a bit of coordination among devs.

@nprofile…53ta If by "sufficiently improve" you mean throwing it away and replacing with a better protocol, then yes it's possible.

2026-02-24 18:05:43 UTC

I enabled compatible IDs in minimitra, so @nprofile…z3wv actor should now be reachable from most fedi servers. Follow/unfollow may also work, but only if your activity IDs are resolvable.

@nprofile…z7ps If you're talking about digital technology, today we have more freedom than 10-20 years ago. But an average internet user has no freedom at all, for them internet is like TV.

@nprofile…d8rs I would use next if collection is already fetched, but in my case the client needs to start from a position where it stopped during the previous sync session.
This is for inbox synchronization.

@nprofile…d8rs Thanks.
I think this could be mentioned in the FEP.

2026-02-21 18:58:36 UTC

@nprofile…d8rs What convention do you use to iterate through an ordered collection? Suppose I need to get items starting with <object-id>.
I don't see an operator for this in FEP-6606: ActivityPub client to server collections addressing conventions

It might be not possible to create a generic #ActivityPub server, but nevertheless this is an interesting thought experiment that helps simplify the protocol and figure out the best way to extend it.
I've been thinking about generic servers for quite some time (because this complements my work on nomadic clients), here are my notes:

Yes, they are building blocks, together with Create, Update and Delete. Everything else can be constructed from them.
