@pixelschubsi @adbenitez we use #chatmail to indicate a minimal mode to operate an e-mail server, namely as an ephemeral store-and-forward relay. On top of chatmail relays, #deltachat provides *always* end-to-end encrypted messaging and minimizes metadata visible to the relay.
Relays forget messages after download, or if a second device is added, after some set number of days. This ephemeral e2ee-only mode is indicated by "chatmail" see also the intro of https://delta.chat/en/2025-03-26-edit-and-delete-how .

@Daojoan meet #deltachat basically displaying email inboxes with a chat UI, and encrypting email without you even needing to know what encryption is

@cehteh #DOOM was one of the reasons the #webxdc size limit was increased in #DeltaChat, it was already ported back on 2023! read:

https://support.delta.chat/t/proposal-remove-bump-xdc-file-size-cap/2828

if you search for "doom" you will find the download link, you need to rename the extension .zip to .xdc

fun fact: it was also ported by the same person that ported #Quake!!!

Russian authorities continue to demand the impossible, namely that we give them user data we don't have. Today the Moscow City Court rejected our objections and sided with the communication surveillance authority Roskomnadzor and the Federal Security Buereau (FSB). Not too surprising.

@schnedan yeah one thing is the beauty of blah blah and another practical reality, most/all xmpp clients are no way close to the usability and user friendly level of WhatsApp and Telegram, heck, reactions started to be implemented in SOME xmpp clients "recently" and it is still half baked last time I tried, I am just answering your question about "why don't people just use xmpp?"

with #DeltaChat you get the same advantages of decentralization while the app is better, that is my opinion

@gerd

@schnedan "xmpp works great" haha, yeah sure, people prefer #WhatsApp and #Telegram or even #DeltaChat because the apps are better (UI/UX-wise) while #xmpp doesn't have a concrete good brand/app that people can install and use and expect the same features everywhere (ex. iOS)

also it is easy to mess up and send unencrypted in XMPP, most groups are unencrypted because it is hard to get it working right in groups and multi-device

One thing radically different in #deltachat compared to Whatsapp and Signal: pervasive, effortless multi-profile support. We understand many worry about how to find others to get in contact with. The dreaded messenger network-scaling problem!

But if you onboard as a *group* that's less of a worry. We aim to ease and further optimize group-onboarding btw. And sooner or later you'll enjoy multi profile. Creating a chat profile without being chained to a phone number. Freedom and resilience.

We increasingly hear about China travellers who use #deltachat successfully where Whatsapp and Signal fail to work. Recently a family onboarded including a 85 old mother, to prepare for China travel. Everbody succeeded, no troubles!

#deltachat is all about resiliency and "just works" user experiences. Despite ongoing and prospective network blocking attempts, our apps manage to mitigate and remain working everywhere. Meanwhile we are preparing some next level resiliency/security features ;)

@wauz @werawelt @ramichaelseidlitz es ist leider nicht erkennbar was das mit dem heutigen #deltachat zu tun hat. Alle, die auf #chatmail onboarden, können weder klartextnachrichten schicken noch empfangen. Deine argumente klingen so generisch dass sie auf praktisch jeden messenger zutreffen und auch auf das internet protocol (IP) selbst. Muss aber jetzt nicht ausdiskutiert werden.

@delta Now, I'm having second thoughts, and I wonder if having at least two accounts (one using a random chat mail for processional use and another with my regular email for personal use) could be a better approach. After all, It is extremely easy to have more than one account in delta and switch from one to another.

#deltachat

@delta I initially started using my regular email address and it just works great. Setting it up was no different from setting up #Thunderbird.

The rationale was that if someone has my email, they could contact me as usual, and I would be able to chat with them using #deltachat

@delta but there are at least two main items with the awhere I'm going to need advice about #deltachat

1. Is it a good idea to use your regular email address or is it better to use a dedicated email account like the chat mails from the onboarding process?

2. Is there any way to discover other people using #deltachat if you don't know their email address if they have not shared the QR with you? (I can see pros and cons for both)

@delta I can see how #deltachat could be equally useful to family members from different ages, activists, journalists...

I've been using @delta for some months and I'm totally in love with it.

The concept of using emails as chats is equally simple and powerful.
And I love the fact that it just works as we are used to in other #IM apps, but without being locked to a platform, and having true encryption.

The onboarding process is extremely easy to do, and does not require personal data at all.

IMHO it is equally useful for non-experts and people who really need a secure and trusftul IM service.

#deltachat

@cy if you want to do so, you can! and you will be able to communicate from your sassy PGP+email setup with non-tech people that on the other hand just want a messenger on the style of #WhatsApp and not to fiddle with PGP keys and configuring a classic email client to properly encrypt messages and read chats in an INBOX instead of a chat conversation.

#DeltaChat is basically making #e2e encrypted #email accessible to the masses without they even needing to know what encryption or PGP is

@kkarhan @monocles @Stuxhost @delta Thank you for your valuable input! It's always enlightening to hear different perspectives on communication tools.
#Linphone Firstly, I appreciate the mention of Linphone. It is indeed a great tool, and I should have included it in my list. Linphone stands out for its versatility and strong support for various communication protocols, making it a robust option for both personal and professional use.

#DeltaChat is new to me, and I am eager to give it a try. However, I am curious: is it just another XMPP client, or does it offer unique features that set it apart? Generally, I prefer les feature-rich clients because I often use just simple text and voice communication. For my personal use case, XMPP is fine when it is compatible with TTS (Text-to-Speech). You're right that IRC and XMPP have their strengths, but I am always on the lookout for tools that I can offer to regular users.

#Signal and Session are both backed by single entities but prioritize user privacy. Personally, I don't have enough experience to delve deeply into the pros and cons of Signal and Session. A significant limitation of Signal is that I can't build the app from source code, and as far as I know, there is no real way to run it on a server OS—it's only available on iOS, Android, and via Waydroid on Linux, with wayland GUI. At least Session is working on x86 architectures. In general, I think both are useful for mainstream users due to their familiar interfaces and ease of use. While Signal and Session do a good job with privacy, they may not be the most secure options, and they certainly don't rank high on the Free Software scale. Would you agree with my evaluation, or could you elaborate on your criticism?

#Matrix is designed to be decentralized and open, allowing users to host their own servers. This decentralization provides greater control over data and enhances privacy. Comparing Matrix to XMPP+OMEMO might oversimplify its capabilities, as Matrix offers advanced features like cross-platform interoperability and robust end-to-end encryption. It's open-source, and I haven't seen any obvious problems with it. Could you elaborate on your thoughts about Matrix?

@delta / #deltaChat is not using #XMPP+#OMEMO (unlike #monoclesChat & #gajim) but #PGP/MIME on regular #eMail,

Last week four new #chatmail relays popped up from four different continents from four different entities.
Permission-free interoperability based on #cryptography ... That's how we like it and how it generally is with the email system: separation of transport and apps. App developers can't access messages, and relay operators can not break e2ee encryption. Fwiw May 14th there is another round at a #Moscow court where our lawyers will convey this impossibility for #deltachat to hand over data.

@pvagner not the least because @WofWca @treefit @r10s and @adbenitez care for #deltachat #a11y for some years now 💗

@scott @peter if you need any advise or support let us know :) We particular recommend onboarding with a pre-existing group because then the biggest roadblock, "who can I chat with", is mitigated. Many families, little orgs and ad-hoc groups like attendees in a conference talk, successfully started using #deltachat this way and particularly appreciated #webxdc apps that provide an in-chat interactive experience.

1 cent per five years .... is the current marginal hosting cost for a #chatmail address, with which #deltachat apps facilitate world-wide private messaging including interactive #webxdc apps that run end-to-end encrypted in any chat group.

<1 Million EUR per year is the estimated marginal hosting costs for 350 Million EU citizens. Such scaling requires, however, research and development, including careful UX and #cryptography work. Related writing from @gordon

https://newsletter.squishy.computer/p/cryptography-scales-trust

screenshot of key excerpt from the referenced post: "When the network is built on cryptographic protocols, we don’t have to trust anything in-between. We don’t have to trust the computers, the wires, the institutions, beliefs, or kinship of the network participants. We can trust the math. All we have to do is verify the message with cryptography. This is a powerful primitive for scaling trust, because it means everyone on the network can cooperate together, even if they don’t trust each-other. The costs to producing high-trust results are greatly reduced, and we can spend our coordination efforts on building larger, more fine-grained, more complex networks of cooperation."

És evident que estic encantat amb #DeltaChat: programari lliure, servidors #chatmail federats (pots tenir el teu propi servidor chatmail!), xifrat punt a punt sense complexitats de cap mena, molt fàcil de fer anar (ideal per a les persones grans), privacitat màxima (no demana cap informació personal) etc.
Però vull destacar una cosa, l'opció afegir un segon dispositiu. És extremadament útil i fàcil gràcies a aquesta opció tenir un segon dispositiu amb tots els grups i contactes sincronitzats.

La missatgeria instantània té diversos fedivers, el de #DeltaChat està creixent amb la creació de nous servidors #chatmail 👏
Marxar de les apps de missatgeria instantània tradicionals (Whatsapp, Telegram, Signal) és molt fàcil si cerques #privacitat total. Descarregues l'aplicació DeltaChat, prems el botó crear perfil i ja està, ja tens missatgeria xifrada punt a punt, no controlada ni vigilada per ningú.

Estic pensant que faré un paquet per #Gentoo per a poder fer 'emerge net-im/deltachat' i gaudir de #DeltaChat a Gentoo.

#BonDia

Yesterday, 20 people from the https://safesisters.org community onboarded with #DeltaChat in Lusaka, Zambia. Everything worked! Usability, privacy and #OfflineFirst ops were appreciated and #webxdc app based organizing met strong interest. Many participants engage in addressing challenges from surveillance state actors, family and partner abuse. Moreover, people with visual impairment were happy about Android's screen reader support.

It's events like this that validate our efforts!

Perfecte, tinc funcionant a la perfecció #chatmail (#DeltaChat) en un servidor Shared VPS molt barat a Heztner Cloud (7,25€ al mes).
Paga molt la pena tenir servidor chatmail propi de missatgeria instantània xifrada punt a punt fins i tot per grups, sense complicacions tècniques de cap mena, molt fàcil de fer anar, a Europa, lluny dels xafarders ianquis i de les apps de missatgeria tradicionals.
Privacitat màxima 😀

#MissatgeriaInstantània #privacitat

Today I learnt: if you configure #DeltaChat to delete messages from server at once after download, you won't be able to send messages to "Saved Messages".
Honestly, it looks like a bug to me, as by definition "Saved Message" are supposed to be for saving them... Would you file a ticket for that ?

We have several ground breaking developments going on in the background, and frankly, it's sometimes hard to not pre-announce them excitedly :)

However, we struggle to acquire public funding after the OTF contract broke away in February. Current need is around ~50K per month for ~10 people. , and we would like to support some contributors to switch their day job.

Fallback: even if funding dries up, #deltachat is bound to continue to work. It's pretty maintainable and intrinsically motivated.

@nanianmichaels for the record, one of the Delta Chat developers is aware of #HomeAssistant and toyed around creating an integration to use DC via web with it:

https://fosstodon.org/@treefit/114116842443275853

maybe creating such a #DeltaChat bot integration would be possible, not sure if @treefit would be interested or have time but otherwise someone else could do it, so maybe the option No. 1 is also possible

@M0YNG

@M0YNG I don't know #HomeAssistant but if it is some service you run in some server, you can create a #DeltaChat bot that runs in that server and sends you #e2ee email notifications

Alternatively, you can configure Delta Chat with a classic email account and receive normal/unencrypted #email so you could just sent you an email notification from #HomeAssistant if it already support it

#deltachat ist a community messenger much more than a monetary focused enterprise. Its offspring developments, the growing #chatmail and #webxdc efforts are also community grounded.

Is there any other cross-platform FOSS messaging project, implementing #RightToExit on many levels, putting all interesting and sensitive computation and interactions into end users devices, constantly and radically denying centrality/control of billionaires and big-tech, to the extent currently possible?

@icaria36 puedo confirmar que en condiciones de mala conectividad en zonas rurales con poca cobertura e inestable y con 2g he podido usar #DeltaChat mientras #WhatsApp, #Telegram, #Signal etc. se quedaban mareadas intentando conectar todo el tiempo, me temo que esas aplicaciones simplemente están hechas para un mundo primermundista hiperconectado con buen ancho de banda, por lo que pasan cosas como estas en situaciones de emergencias

@ufm fun fact: there was an app that allowed to use #yggdrasil for #p2p messaging in #DeltaChat: https://github.com/deltachat/AndroidYggmail/

but yggmail has all the problems of p2p apps so just setting up a #chatmail server inside yggdrasil network is probably more interesting

Some of you may remember posts where we talk about #deltachat being hardened to work under bad and adverserial network conditions where other messengers fail. Examples were Georgia, Russia and Iran at the time. But hardened network handling can be useful also during non-political turmoil like currently in Spain where there are some reports that DC messages get through where WhatsApp failed .... https://sonomu.club/@icaria36/114417052677227592

In any case, wishing all the people in Spain and Portugal quick recovery!

@icaria36 yes, currently if your chatmail or email servers fails you wouldn't be able to get messages.

The reason why #deltachat might work better is because it has been optimized to work in bad networks where states are intentionally trying to disrupt communications. Maybe the power outage in spain causes more random network behaviour (eg DNS failures) which delta is pretty prepared to deal with. In any case thanks for the notice and all the best with restoring power!

Still... I guess even #DeltaChat communications would fail me if the data center of my ChatMail server would be affected by a power cut, right? Or is there some kind of redundancy?

No idea how accidental this #blackout is, but it's a good chance to think how to make your mobile phone still useful when a bunch of servers (including your default ones) go off.

There is an ongoing massive electricity power #blackout in Spain and Portugal. Some of my friends are reporting that not even WhatsApp is reliable, working for some contacts and not for others. I'm still trying to understand how this is possible, and maybe it has to do with the recipients'nearest telecommunications more than the WA servers.

Anyway, fun fact, the friends who reached out did it via #DeltaChat

Still... (next)

@beaufils if you have any questions about #chatmail relays or #deltachat apps let us know :)

Please help us get rough stats as we don't have technical means to collect such stats, by design.

Do you use #deltachat or are considering it? Which kind of operator do you use?

23 is the number of currently active #chatmail relays we heart about by now. Only 6 are listed at https://chatmail.at/relays to complicate ongoing state-level blocking attempts. Please keep setting up #chatmail relays -- and thanks to all the early adopters and carers!

July 2025 some key contributors will do sessions in #Lille, France at @passthesaltcon
and discuss the state of efforts to scale #deltachat #chatmail and #webxdc to billions of people and bots, without any central points of control.

"if your social media network can go down it is not decentralized" they say and rightfully so. Same is true for much other infrastructure ... Energy, water, internet utilities ... And of course messaging. If your messenger can go down it's not decentralized. During 2025 we aim to make #deltachat and #chatmail infrastructure in particular into the most resilient and mass-user accessible private messenging utility out there ... If it isn't already :)

@bitsoffreedom Signal is no proper alternative to WhatsApp if you want to be independent of US, and have digital sovereignty, take a look at #DeltaChat https://delta.chat

@ct_Magazin wie kann man 2025 bei "sicheren" Messangern noch an @delta #deltachat vorbei kommen?
bzw. allein die Geschichte um die Entwicklung wäre vermutlich einen eigenen Artikel wert.
vielleicht mal @hpk kontaktieren.

@yawnbox @Xeniax @zelf the other reason for not formalizing procedures completely is that the requisite parts are still evolving. #deltachat #chatmail and #webxdc efforts each have their own dynamics, and the particular dynamics have particular sub dznamics and all the borders are constantly shifting, renegotiated.

Sorry if this makes getting an overview from the outside harder. We do try to constantly publish about our considerations and all coding work happens in public.

Organizational note: It might appear that #deltachat #chatmail and #webxdc contributors are easily "on the same page". In fact, there are many ongoing controversial discussions in backrooms and public spaces. We are dealing with tons of user perspectives and feedback, researcher and developer stances, many UX/UI considerations, complex implementation and platform adaptation. We are internally allowing contradictions and complexity ... See also Ashby's requisite variety https://edgeofpossible.com/ashbys-law-variety-organisational-change/

#deltachat #delta

Today we are unveiling two brand new features by ... drum-roll ... doing nothing:

- No "AI" integration involved or planned. Consequently, you don't need to teach your relatives how to disable AI!

- No proprietary server components: servers are fast, efficient and freely replicable, no permissions needed!

Moreover, our apps are easier to use and onboard with than SIM/phone number based apps: Multi-device and Multi-profile handling is a piece of cake.

#deltachat #whatsapp #signal #matrix

Al arrancar de 0 en un nuevo ordenador, me acuerdo de por qué XMPP no puede triunfar (así), y por qué Delta Chat gana cada vez más puntos...

Con #DeltaChat, añadir un nuevo dispositivo está a un QR de distancia. Y pum: lo tienes todo a tu disposición. Todo. Sin barreras. 100 % encriptado.

Con #XMPP, haces lo mismo, PERO literalmente pierdes la posibilidad de leer TODOS tus mensajes antiguos. ¿Qué MI***A es esta?

Es imposible considerar a XMPP como algo serio así. Sinceramente.

@mondstern @meshtastic wow - #deltachat in acryl 👌

@risturiz I think email servers already support some sort of multi-server setup for the same domain, but #DeltaChat will be adding "multi-transport" support to the app which basically means a single profile can have several email accounts associated at the same time so if one fails others will still work, this has the advantage that you can even use servers with different domains and providers at the same time so if one goes down or blocked others will still work

@kuketzblog what are the "Delta Chat missionaries" saying? 🤔 I am one of the #DeltaChat developers and I don't think any of us claim Delta Chat is some "state of the art" perfect or "the best", "the fastest" etc as other messengers boldly do.

The selection of parameters of comparison in your messenger table is also subject to what you think is important, it is hard to be neutral, also it seems the "metadata protection" field is not completely correct for Delta Chat:

Now using #DeltaChat with my own mail server.

Nice thing (on desktop) is that DeltaChat could also serve as a
Mail User Agent, too bad they are removing this part :)

The trajectory of E2E-encryption is about de-platforming: There shall be no central machines that can control the edges/peers, and the social groups and virtual centers they freely form.

Our #deltachat R&D around #chatmail relays and #webxdc apps all aim to realize such a "zero-platforms" fully E2E-encrypted interaction model. However, this is *not* just about cryptographic cleverness. Rather it is about usable anti-authoritarian designs, as explicitly stated in January https://delta.chat/en/2025-01-23-webxdc-no-billionaires

@krafter Delta Chat is available for iOS, if you mean in general to install a new app well yeah if people don't want to change there is nothing you can do about it, but if you are not available in the platforms they use they will need to use something else

on the plus side with #DeltaChat there are in-chat mini-apps you could use as a reason for them to install the app, ex. shopping lists with family or roomates, split bills with friends, to-do lists and collaborative editor, games, etc.

@krafter I recommend you to give it a try to #DeltaChat, for android there is a nice client called #ArcaneChat I maintain:

https://arcanechat.me

Easter/April offer 🐣 if you are onboarding a small group of family/friends to #deltachat and/or want to setup a insta-federated #chatmail relay let us know about any issues. Just post on fediverse and tag us. In case of bugs/issues we'll see to privately set up a support chat to help sort out any issues, or file accordingly to our development tracker. We want Delta to work flawlessly for private chatting and to better understand any remaining irritations or problems. Thanks and enjoy :)

Isn't it ironic that a messenger that utilizes email protocols under the hood is pretty resistant to spam? For decades most people equated email with "spam" and yet, here we are. It's not the email protocols that cause spam but the fact that email adresses have been used as identity. #deltachat is moving away from this email address-as-identity model towards a cryptography based model where only chat contacts know your identity, and email is "just" the globally federated transport.

If you are using #deltachat with a #chatmail profile with private contacts there is no chance you are going to get spam. Why?

1) Spammers can't contact you based on your phone number like with other messengers.

2) Nobody knows your private address or cryptographic key except your contacts. Without that spammers/phishers can't contact you.

3) if joining a public group with unknown members better use a second chat profile which you can mute/remove as needed.

Privacy and peace of mind.

#deltachat is geared and optimized for private messaging even though it's successfully used for 100+ people chats as well. Doing large scale chats has two challenges:

- implementing scalable encryption so increased number of recipients does not increase message size/cpu cost for the sender

- grow good moderation tooling because public channels/chats invite a lot of spam, unwanted stuff

For large chats today we recommend to control who joins, and maybe use a separate chat profile.

#DeltaChat is so much better than Signal when it comes to hardware support. Get this: when setting up a new phone I lose access to previous conversations and media DESPITE having a synced desktop app. Why?

Well in Signal your desktop client is not a real client! Switching hardware with #DeltaChat was quick, easy and successful. Every client is real.👍

Signal:😖

I do wonder why they fail so hard there, as they generally have things figured out, too.

#openpgp traditions and #signal both bind a cleartext identifier, phone number or email address, to a cryptographic key. It opens up attack vectors as the servers/orgs controlling this binding can interfere.

#deltachat avoids such cleartext identity bindings by creating random #chatmail addresses, as transport only. The cryptographic key becomes the identifier and we want it hidden from the transport layer. Only people being in end-to-end encrypted chat need to identify each other, after all.

@AAMfP @goose @dammn yes, our whole project is about proving in reality (meaning: working code) that email protocols can be streamlined for instant messaging. #chatmail relays provide low latency always end to end encrypted interoperable messaging. The family of #deltachat apps work with the permission free chatmail relay server network but also with run-of-the-mill email servers. Just make sure to use a dedicated chat address and don't mix classic and chat email on the same address.

@sebiturbo I recommend you #DeltaChat and if you are using android there is this nice client I maintain: https://arcanechat.me

@werawelt kleiner typo: der fediverse account von #deltachat ist @delta

The tech oligarchs, embodying and collaborating with authoritarians, are the horror artefact of the immense power that lies in configuring and operating our digital infrastructure we live and love on. Cryptography may mitigate toxic infrastructure but eventually we need to find and arrange more convivial ways for going about our lifes. #deltachat and #chatmail are small contributions to people-sovereign convivial infrastructure. DM us if you need support setting up a new chatmail relay :)

@Thomas1108 we hear you. Changing messengers is serious work. There is no need to rush if you just moved to signal. It's a fine choice. For the time being, it would be suicidal for the US corporate operators of signal's infrastructure to use their power to compromise it. They could loose tens of billions of revenue with customers outside the US if they did. Maybe just consider #deltachat your insurance and a thing to eye mid/long term. Email will not go away anytime soon :)

I said it before on Mastodon. I'm reposting this again. Comparing #DeltaChat and #Matrix together, if you want hassle free and consistent messenger for private #E2EE chats, don't go for Matrix. DeltaChat is way better.

However, if you want something like a public forum, or a public chatroom, don't go for DeltaChat. Matrix is way better suited for that. And DeltaChat does not support public groups at all. In DeltaChat groups, there is no admin or moderator and everyone have got permission to remove or add the others.

I think I have to write a longer post on my personal blog about these two, comparing them together.

PS: Another Matrix encryption bug few minutes ago triggered repost of this.

@delta @fasnix @Gerbsen @qbi Du weißt das, ich weiß das, alle #DeltaChat Nutzenden wissen das … mein Zitat war die übliche Antwort darauf, wenn man jemandem diese App vorschlägt.

Es ist immer das Problem einer kritischen Masse. Und Influencer:innen können an der Promo für DeltaChat nichts verdienen, also lässt sich diese App / dieses System nicht zu einer kritischen Masse pushen.

Zum Glück ist DeltaChat für alle Platformen verfügbar und nicht wie #Briar nur einer kleinen Gruppe zugänglich.

@Gerbsen @qbi @signalapp
Oder man verwendet #Deltachat und nutzt weiterhin eMail.
Kann nicht erkennen, welche Nachteile Deltachat gegenüber Signal hätte, es sei denn, man vertraut einer Software mehr als einer anderen.

Public service announcement:

1. If you want to link your #Fediverse profile to a chat account please consider just saying "DM me for #deltachat invite link" and NOT PUBLISH it to "all".

2. If you do publish invite links to groups and so on, please consider doing it with a dedicated delta chat profile that is not your private profile. Multi-Profile for the win.

3. We want to evolve the #securejoin invite link UX to better prevent unsafe practises. Involves tons of considerations. 💜

With our #deltachat #chatmail and #webxdc efforts we put all intelligence on the end devices, and architecutally separate it from a transport layer that routes safely and fast but knows nothing.

There are a dozen or more #chatmail servers across many jurisdictions, all safely interopable with each other and classic servers.

Turned out we can dumb down email servers by relying on cryptography instead of IP reputation and ai/spam filtering. And have 200ms delivery times. We are not done :)

Did you know that #deltachat does not need and does not use key servers? Most other messengers (wa/signal/matrix/threema/...) actually operate or incorporate a cryptographic key server, managing the cryptographic identities of all users. Delta Chat uses decentralized protocols for key management avoiding a central storage of identities. The SecureJoin protocol is the key (sic!) innovation and was independently analyzed by ETH Zürich researchers earlier this year .... https://delta.chat/en/2024-03-25-crypto-analysis-securejoin

How many people do you know that have lost their messaging history on Whatsapp or Signal, photos etc during mobile phone transitions or breakage or through other shenenigans?
