 along with templates to replicate the setup, without needing any permission. Two weeks ago we thought there are 60 relays when a hacker handed in a 100+ list 😂 A bunch of knowledgeable folks are now maintaining track of health of the evolving global network, and supporting new operators. 💜💥🖤 thx also for all the support here on the fediverse! its been a wild year and #39c3 is in 13 days to top it off 😅

 are spearheading ever new and more fun ways to deny power to servers and platform billionaires. Unlike classic email servers, #chatmail relays do not store user identities which solely live on end-user devices.There also is no encrypted value on the server like with Proton Mail or Signal. There are only relays, endless federating networks of relays to onboard safely :) image

 Another nice surprise! A careful discussion and appreciation of our almost 8-year long running efforts, and its #deltachat and #chatmail artifacts. The "Signal contingency plan" comes complete with podcast, website and zine! View quoted note →
A few things #deltachat apps are doing positively different from #Signal apps - easiest onboarding ever; not depending on phone numbers or other private data - support for multiple chat profiles/identities - decentralized servers, not depending on US-based GAFAM etc. - migration from one app/platform to any other - easy multi-device support for any chat profile - developers have chances to get their PRs merged :) - mini-apps support via

Well, maybe we need to be more clear what we are trying to do: #deltachat apps are a cross-platform private messenger suite, that aims to provide a consistent UX/UI for users with lots of experience using WhatsApp and Signal. Telegram has good fast UX but is hardly a private messenger (it has a central cleartext database of everyone and everything). Matrix and XMPP are well-esteemed fellows in federated messaging, but so far didn't grow a WA/Signal-level cross-platform messaging UX. YMMV
For those who used all three of Whatsapp, Signal and Delta Chat in multi-device mode: Which messenger provides the best multi-device setup and handling for users (UX)? (question spans setting up a second/linked device, as well as migrating to new device, as well as quality of multi-device synchronizing/bugfree-ness -- all subjectively weighted by each voter according to their subjective experiences)
Signal just released a "poll" feature with great fanfare, while all #deltachat apps already integrated a full suite of chat-shared apps, checklists, polls, shopping lists, calendar, editor + tons of games. Better, anyone can create new apps, eg as github/codeberg forks from existing apps, and post it to their chats for instant deployment. No need to ask for permission, register an account, and no hosting or DNS: actually "server-less" and fully end-to-end encrypted :)

Any data that is collected on servers will eventually leak or be abused otherwise. By design, no one can enumerate #deltachat profiles which are private and not published on any server. Conversely, #chatmail relays do not see or collect private data or metadata. But wait, there is more :) We are currently evolving end-to-end security protocols and UX to **survive an attacker fully taking over a server**. The attacker shall not even be able to message users, let alone impersonate anyone. image
