Perhaps Americans should start preparing with Meshtastic / Meshcore, just in case....... ..,..the Emperor seems hellbent on bringing martial law into effect.

Meshtastic is both extremely range limited and trivial to DDOS. It's a fun toy protocol but it's not resistant to nation state disruption at all.

I looked a bit into meshtastic and was told that if a node was physically compromised then messages could be intercepted. That cant be right, right?

Why bother? Just jam the fucking hell out of it. Most critical infrastructure is not on the ISM bands.

I'm still unclear how the stated goal of the title is achieved. My first assumption reading the title that it works something like airtags, but that is obviously nonsense. unless you are standing right next to the guy you want to message, how exactly does it work?

https://briarproject.org/how-it-works/ Looks like clients re-host posts to their friends in a p2p fashion.

Thanks. Basically it depends on c travelling to another town. Also taking the risk of being caught with the content on it's phone. It looks like a great app and every little helps but hardly a game changer, unless i'm underestimating how bad it is in Iran?

If it works via tor it's probably also slow, but that's a small price to pay for not relying on a central server for people with legitimate concerns or problems with connecting.

Earlier quoted context omitted.

The military can very easily find and eliminate repeaters very quickly and almost certainly would.

Then get more? Sounds like a fantastic way to waste military resources. I have no clue why this mythical US military might and efficiency idea persists after so many failed interventions.

You must have missed the S-tier op that went down January 3rd.

There was a well known crypto weakness, CVE-2025-52464, that allowed man in the middle decryption of meshtastic traffic. It was fixed by a firmware patch that improved crypto discipline.

Can you expand on that? I'm from a developing country and we're very worried about what's going on in America. Is the situation really as bad as Iran?

No. It's nowhere near Iran, but it's bad by typical US standards.

I'm curious about the iOS situation

I doubt iOS has a large market share in Iran. Also, for something like this you don't want a platform that requires you to essentially use the App Store and nothing else.

iOS is around 10%, Android around 90%. (https://gs.statcounter.com/os-market-share/mobile/iran/%20)

It's only line-of-sight, but isn't the range 10s-100s of kilometres in open areas? Some repeaters on hills/mountains etc. could connect large areas potentially.

The interventions fail only after enormous slaughter, which people are understandably keen to not be subject to

As if compliance had such a great success rate.
