Sabato 5 aprile parlerò ad una riunione didattica con il #NaLUG riguardo le piattaforme di #chat libere e #opensource, decentralizzate e private. Maggiori informazioni qui sulla riunione e su dove si terrà: https://www.nalug.tech/nalugunina-sabato-5-aprile-2025/.

Currently testing our new #chatmail server.

WE LOVE IT!

Thanks @delta
It's so simple!

A new project is underway and Chatmail (DeltaChat) will probably be part of it (still testing).

Coming from Matrix, it is a blessing that these options are finally available (see picture)!

@feld
Thank you for your text about #DeltaChat bots. The article helped me a lot to quickly program the basis for a bot.

@delta I keep trying other messengers, including xmpp which I also love, but keep coming back to #deltachat it's so snappy, clean and I never have any issues with keys/encryption ... it just works!

Hello Fediverse! #introduction

dComms is a project by eQualitie that provides a curated and secure deployment of decentralized communication tools for civil society including #Mastodon #Peertube #Element #DeltaChat etc. #dComms creates small-world networks for reliable communications in low-bandwidth environments, resistant to censorship and shutdowns.

We are now actively working on server deployments in partnership with NGOs in 5 countries and help local communities #migrate to the Fediverse

@reallylazybear I hate to be the bringer of bad news, but you are bound to get problems, it seems they require you to re-connect with the phone from time to time, it seems it doesn't really support multi-device without a dependency on a main device, for an app that has good multi-device without phone numbers check #ArcaneChat (https://arcanechat.me) and #DeltaChat

for problems with signal multi-device see:

#Signal took a huge bet that running on US big-tech toxic infrastructure is fine because its groundbreaking and industry-shaping cryptography is crafted to neutralize it and keep users safe.

But is it really feasible to live on toxic infrastructure in the longer run?

#deltachat rather takes a bet on the massive e-mail server network and interoperable protocols, and on #chatmail servers which enforce message encryption and metadata-minimization.

Delta is for when centralization turns sour.

Signal is from US, and operates in AWS servers...
take a look at #ArcaneChat https://arcanechat.me
and #DeltaChat https://delta.chat

Did not know this, but you don't need to care about up reputation for #deltachat. 🤯 Makes complete sense why, as it's not using email like a regular email Case in point, very much still outstanding. 😎

@feld @delta I thought the blog post was good, and two points really stuck out:
1) For ease of adding contacts, since you can scan barcodes between smartphones, Deltachat might as well be another Signal or WhatsApp (for how convenient this is). I had to admit that scanning a barcode to add a contact is becoming more commonplace by the day - kudos to #deltachat for supporting it.
2) When migration to another server was mentioned as being so easy, thanks to AEAP - "Advanced Email Address Porting" - that seriously blew my mind. I jumped out of my chair and exclaimed something to the effect of "shut the front door!"

@feld another point people miss: unlike on #Signal, #WhatsApp, #Telegram, etc where there is a central server watching all the social graphs of the whole network, in #DeltaChat and other decentralized platforms like #XMPP what a server can see is pretty limited and fragmented, We started talking about activists btw, and having the freedom to choose a server instead a central server potentially collaborating with your enemy is a killer feature

@k3fnb @VeroniqueB99 @SrRochardBunson

@k3fnb just because #DeltaChat uses the email protocol you are making some wrong assumptions that only apply to classic email, sure if you go doing activism using #gmail that is not safe, but to use Delta Chat, you don't need to provide ANY personal data / metadata and hence can't leak metadata, you can create an anonymous account for a protest and throw it away afterwards, if cops get your phone they get random contacts not phone numbers unlike in #Signal etc.

@SrRochardBunson @VeroniqueB99

Decentralizers, attention! :)

Last #deltachat releases introduced stable #p2p group membership not found in any other messenger. Members can add/remove peers also while being offline, and when everything comes online again, everyone has the same consistent membership view. We formalized and ran a simulation model using #TLA+ (invented by Leslie Lamport of vector clock fame):

https://github.com/chatmail/models/tree/main/group-membership

and a complementary #pytest model with more corner cases tested here:

@feld @collectifission @davidbenque @sirjofri #deltachat for many years did not have push notifications on android and worked fine on most phones. In some cases people had to enable a permanent background notification to keep IDLE alive. But most often, messages are received in the background on Android without push.

@mikalai good point! The first years we had to make do with classic email servers. We barely expected anything else than "send message" and "receive message" to work. There was no way to get big email providers to change anything. When we then went for the #chatmail concept it meant the server doesn't need to do anything than to transport the message. No metadata, no rooms, no group state that most other messengers keep on their servers. Crossing out server state makes #deltachat p2p-ish

The downside of our project approach was that we often got experts being very dismissive on re-using email and #OpenPGP ... and there still is some opposition which often subsides when actually trying #deltachat and #chatmail, looking at security audits and our strong usable security focus.

There may also be surprising upsides. The UK "Online Safety Bill" which attacks end-to-end encryption integrity seems to not apply for ... e-mail. Because everyone knows, e-mail is unencrypted, right? :)
