How does it handle spam?

Briar uses a rendevouz system for adding contacts over the internet: https://code.briarproject.org/briar/briar-spec/blob/master/p... And a 2-party QR code protocol for adding contacts in person: https://code.briarproject.org/briar/briar-spec/blob/master/p... In short, both these methods of adding contacts require both parties to actively add each other in the same time period. So even if you post your briar contact c…

Thanks. I meant more with respect to users spamming forums - to send a message to a particular forum do I just have to know of its existence? Or is it that each user only sees messages from its contacts on each forum?

A Briar user can either create a new forum, or get invited via a Briar contact that is already in an existing forum. There's some more info on this topic in Briar's user manual if you're interested: https://briarproject.org/manual/

Briar also has the ability to introduce contacts to each other, so while it doesn't support totally public forums, you can spread information between contacts fairly effectively.

Seems like Briar might be good for messaging to young kids. I could give them an old phone without a sim card, and run Briar on it.

What is your motivation for the "without a sim card" part? If the phone is connected to Wifi then they're either at home or at school--isn't the point being able to reach them no matter where they are? I'm not too keen on my kids being on the internet all day. In my case the opposite solution seems better, a dumbphone so I can reach them, but TikTok can't.

Shared custody? I like being able to communicate, send/receive pictures/videos, do videocalls with my daughters when they are in their mother's place without having to ask her to share her phone for that.

I am actually travelling 10 thousands kilometers away from them for a month, having an instant messaging app is a saver for both me and my daughters.

We are currently using deltachat for this with email accounts I set up for them. They don't even have access to these accounts outside of deltachat yet and they can't be reached by others like they would with whatsapp.

Another mobile-only messaging app. If I wanted to use my phone, I'd just use SMS or RCS!

The desktop app is currently in development: https://briarproject.org/download-briar-desktop/

Interesting - the Java version runs on Windows[0][1]! I suppose I'll check it out, then.

[0]: if you drop a dependency into the jar - https://github.com/JetBrains/skiko/releases/download/v0.7.40... (you want the DLL, the checksum, and the .dat)

Are you able to get messaging working on Windows? Their website says they only support linux currently.

I am waiting for Matrix's P2P support, once its out, its going to crush everything else. Supposedly its should come out with the improved mobile apps too, which are sorely needed.

Matrix is so buggy right now without p2p, so I doubt it... specially when it comes to decryption

Bugs in a frontend implementation ≠ bugs in the protocol

It’s not really more work; it’s just a matter of enabling the ‘client isolation’ setting on the wireless AP. For example, see Cisco’s Meraki documentation: https://documentation.meraki.com/MR/Firewall_and_Traffic_Sha... > With Client Isolation enabled, clients will only be able to communicate with the default gateway and will not be able to communicate with any other devices on the same VLAN (or broadcast domain). In…

Even that extremely minor step counts as “more work” for the clientele we’re talking about here.

I would certainly expect a cruise-ship-wide paid network to be managed professionally.
