Speaking of p2panda in the wild: @npub16n7…c97d will soon be hosting a group discussion and hands-on workshop exploring peer-4-peer: an approach to building digital tools rooted in the concepts of mutual-aid, free software, offline-first and peer-2-peer.
p2panda hacking in Go?! :shocked_pikachu:
Our excitement levels are at all-time highs!

Meet us at DWeb Camp and Local-First Conf! 🐼🧳💨
DWeb Camp takes place 08.-12.06 at Alte Hölle in Brandenburg: https://dwebcamp.org we'll be organising a little p2panda meetup and @npub17p7…npt6 will moderate a panel on "The Future of P2P Data Types" 🔬 with Aljoscha from Willow and Santiago from HyperHyperSpace!
And then we'll be presenting our work with @npub1k6e…gqwv and p2panda at the upcoming Local-First Conf 2026 in Berlin (12.-14.06): https://www.localfirstconf.com

We aren't there. We'll have to mark this on our calendars for next year; looks like fun. Hope you have a great time!

Hui! This is #p2panda doing #localfirst sync over #LoRa in a #mesh network 🐼 📻
We're experimenting currently with a log-based, replicated delay tolerant / store-and-forward protocol using the RNode transceiver firmware. All very early but fun!

We've been busy implementing p2panda's high-level Node API!
It's an opiniated - but also much easier to use, out-of-the box p2panda stack: the thing which orchestrates all of our individual modules without all the footguns you might encounter when trying to assemble them yourself.
Example:
let node = p2panda::spawn().await?;
let (tx, rx) = node.stream(topic).await?;
This does networking, discovery, bootstrap, sync, event streaming, ordering, storage and more! Let us tell you more about it:

Groups from p2panda-auth offers a solution for decentralised group management, exactly how you use them in your application is up to you. For sure you can have a sub-set of members who are admins / writers as you describe, and all other members have only read access. If you're describing a use case where even non-members can read posts in the forum, then these identities would not need to be added to the group at all as requests could be handled independently of groups.

could you expand on your meaning of "world-readable" here? It's not immediately clear to me what this means.

We're still processing all the great discussions had at the P2P Basel workshop this year! Deep technical experience and insights were shared around the table, with folks from Uni Basel, iroh, SSB/tinySSB, Braid, Willow, Cabal, Qual, Pijul and p2panda in attendance.
There was a lot of discussion about how we might share some of those conversations with wider circles, possibly through a podcast? Any interest?

OUT NOW! Our Part II Blog Post on building a convergent, offline-first Access Control CRDT!🍿🪩🧨
https://p2panda.org/2025/08/27/notes-convergent-access-control-crdt.html
Integrity, Provenance, Partial Ordering, Linearization, Concurrency, Conflicts, Consensus, Finality, Equivocation, Byzantine Fault Tolerance and Eventual Consistency, ..
This contains a lot of notes about what you might want to know when building a data type which should be collaborative, convergent and decentralized.

Yesterday the "Reflection" project started officially as part of the new @npub1y8k…05lv round! 🌟🌈
The team consists of @npub1a2z…v48a and people from the GNOME gang around @npub1dkc…3gke and @npub16d8…0x8u.
We gonna release "Reflection" (formerly Aardvark) - a GTK-based, collaborative, local-first text editor! Aaaand:
All of this is part of a larger effort to explore p2p code, UX patterns, reusable UI components, debugging tools, organize events and document our learnings.

Two weeks ago, the p2panda core team gathered in Berlin—hanging in the park, forest, and the "Cultivation Space" in Wedding.
We focused on aligning our efforts around new encryption schemes, robust atomic transactions, groups, and access control.
This is the first big step towards unifying our work into a "super pipeline" that will enable apps to manage access, secure data, support relays, handle multi-device setups, and more.

This week we did a working session in BOARC, Bidston Observatory, an amazing self-organised community center close to Liverpool, UK (with a radio station in the basement!).
We finalized and tested the first, experimental prototype of Toolkitty, an mobile and desktop app for collectives to share resources & spaces and organise events!
And we launched it's website! 🥳
