The ecosystem is moving ... away from corporate centralization and mindsets.
Billionaires are out, federated and multi-player systems are in, if we gather the many chats, gossips and happenings around #fosdem correctly. Dispersing ourselves around Bruxelles the last couple of days was very enjoyable (thanks Sun!) and helpful to orient in convivial directions in this otherwise extraordinarily stupid 2025 timeline ... thanks to the many people we enjoyed conversations and hang outs with! ❤️
Picture of entrance to "Delta" subway station close to the ULB Fosdem conference location. It's beginning February, trees mostly have no leeves, and there are wall paintings: a kind of animal/human in black on yellow ground, as well as a yellow/blue towerlike structure with some red and black graffiti. A stairway and two machine-rolling stairways are visible, one of them currently blocked.

distribution, not federation. Federation has its own problems. I think the approach of relays instead of federated servers is more mature.

Federation is not just a technical but also a social direction: different groups can have have different policies yet federate .... The #fediverse and activity pub also provide an upgrade protocol for lifting existing media platforms into the fediverse. There is a lot out there already and you can't rewrite it all.

federation can't solve all problems only replace big corporates with server admins, many problems still exists.

we need distributed services, neither federated solutions nor p2p solutions.

And with details we'll be able to ask higher level info security questions.
Also let's comment, how on level of details, delta manages to have chat like aspects, while delivery/high-level-transport isn't aware, unlike say Matrix. In classical federation transport and metadata-rich aspects are mixed. Delta shows how it can be different.
Details are revealing. Details, please.

it's indeed a good question how #deltachat avoids storing group metadata on servers. The answer is it implements a P2P group membership model (briar often described as a P2P messenger does have a centralized group membership model btw) . Here is technical documentation about our TLA+ modeling https://github.com/chatmail/specs/blob/main/group-membership/README.md#modeling-group-membership a complementary python simulation model https://github.com/chatmail/specs/tree/main/gmc and the just merged rust implementation rolling out in releases https://github.com/deltachat/deltachat-core-rust/issues/6401#issuecomment-2575938346
