    Would ssb (secure scuttlebutt) with Yubikeys have a similar usecase? [0]

    Take heed, Americaneez -- and prepare, because this may be in your future sooner than prediction markets would have you believe [1].

    LoRa mesh networking seems like the runner-up, but vague reports indicate (Meshtastic) doesn't handle crowds well.

    I think Bitchat can use Meshtastic, so a LoRa radio paired with a phone could be a base for not just texting individuals, but community messaging.

      If there is really a civil war, won't these frequencies just get jammed?
      • futuraperdita14 minutes ago
        The point to any preparation for any adverse event is to prepare more than one solution to a problem, and to have a solid understanding of your actual adversary. By asking that question, you have already defeated yourself on the sake of whomever you have decided is the dominant force.

        Won't they get jammed? Yes, absolutely, on local levels. This is electronic warfare and happens in any actual battlespace.

        Does that mean it is completely useless in emergency situations (of which civil war is one)? No.

      • zmgsabst17 minutes ago
        The US is huge — you can’t jam everything everywhere. Talking about just cities, you still can’t jam everything everywhere.

        But yes, targeted suppression/oppression (depending on your allegiance) will almost certainly use jamming — in fact, I’ve spoken with some Antifa about how they jam EMS frequencies at their events.

          This reminds me the way the software was distributed in eastern countries when there was no internet. People went to market to meet other people, and they were colporting (look up the term if you need) cassettes with the software.

          The same can happen now - people would walk down the streets to certain places, to become hubs of information, but with no physical contact. Of course those places would be were the jammers would head to.

    Does anyone remember yik-yak? It wasn't anonymous and resilient like briar, but it was great in its time to discover people near-by and start chatting.

    Does anyone if briar relays traffic? like if at least one person in a wifi network has briar and they also connect by bluetooth to another person within an adjacent wifi network, does it relay messages from one end of the city to the other over dozens of devices?

    • cookiengineer2 hours ago
      No they sadly don't have that, and that's the major issue of connectivity. All chat recipients have to be online/reachable to receive your messages, which is okay, but useless in mobile environments where you can't afford that constant traffic.

      The broadcast type channels though are what the article talks about, they are great for off the grid and mesh environments.

      Relaying and scattering traffic across neighboring peers (and handshakes via multicast DNS, for example) would fix a lot of the issues you'll get with Briar, but I guess that would imply a refactor of the codebase.

      For these types of NAT breaking issues, a lot of protocols rely on STUN/TURN/TURTLE routing.

      For my experimental software router I'm relying on broken firewall deep packet inspection, so I'm using exfil / smuggling protocols. Currently still works, according to my local setup of the great firewall (it's source leak was legit btw).

    I have Briar, but never had anyone to use it with. As an emergency text messaging tool, I guess it can be used, but not for any media transfer. The picture quality is abysmal. I also tried using it to sync some notes across devices, looking for a good use case of it all, but there was also some issue there. I believe once you created a "forum" you can no longer delete them. The desktop app is very slow. Sometimes had to wait for 10-20s for it to do something. I guess it is really just an emergency/offline text message tool.
    • ozfive4 hours ago
      A good use of briar is having it on your phone already so that during a natural disaster you can connect with others that already have it at community relief spots. Keep it just in case and it will come in clutch when you need it most!
      • wafflemakeran hour ago
        Briar comes with ways of sharing it offline, so enough for one person to have it.

        Most likely how they got it in Iran, as I doubt that critical mass of people had it installed in advance. Most likely doesn't work on iPhones though - no sideloading.

        • 9dev17 minutes ago
          I looked into the iOS issue once, and in the EU at least, it should be possible to add a minimal implementation of the store API to an app, so other iPhones could download the app from an iPhone hosting it.

          After discovering the amount of pain involved with that API, I quickly discarded the idea though

    >> "The adversary has a limited ability to persuade users to trust the adversary’s agents - thus the number of social connections between the adversary’s agents and the rest of the network is limited." [1]

    This assumption seems risky.

  • wolvoleo3 hours ago
    I think meshtastic would be a lot more performant in mesh scenarios due to the added range of LoRa. But of course it's special hardware and thus suspicious during an insurrection. And probably just not available.

    I doubt this will actually work though except in the densest city.

    • gh02t2 hours ago
      Meshtastic also struggles with high density and high traffic networks. Some modifications can be made to work better, but with the default settings it really grinds to a halt, and modifying the settings to be better suited requires some expertise and foresight. It works amazingly in off grid, relatively sparse networks, but it's got some major limitations.
      • wolvoleo38 minutes ago
        Yeah I always wonder with these mobile ever changing mesh networks: how do they prevent messages from aimlessly looping around the network? With all the mobile devices they're too dynamic to make routing tables and broadcasting everything leads to network saturation really quickly. You could give them a very short TTL but then the reliability will suffer a lot.
  • syntaxing4 hours ago
    Whoa, I was just mentioning in another post how I have my family member install bitchat just in case for emergencies. This is a very interesting alternative. With a travel router, I can significantly expand the chat radius compared to bitchat's purely BLE approach.

      Dude.

      Back in 2014 when briar or something similar came up, we found the app.needed to signed in "online" first then it could be used offline.

      There were apps used in 2019 but it wasnt enough.

      The government "banned" 14 appps including element "because use by terrorists" meant anyone using element after the ban got a loud knock on the door by the stazi with 100-300 personnel, fully ready to engage in battle.

      Have seen horror stories.

      They used isp data to locate homes where element was used and then staked them out and made a big show of attacking at night.

      Then the usual. Phones are confiscated and literal spyware installed.

    I like briar for the fact that i already have the hardware...

    I like meshtastic for not needing the network related devices for their hardware

    What I'd like is something that is platform agnostic... I want an app that i can install, a (tor like) server i can setup that will anonymously route and fwd messages and really cheap and easy hardware that will let me pop up mini repeaters on demand. Would also like to be able to send images and maybe videos, but for the network to be smart enough to only send them when the bandwidth is there

    I may just stick with briar in the mean time, but seriously none of them seem to offer what i want.

        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.

            Triangulation is damn easy. If the US can put on bomb on a suspect satellite phone user back in the 2000's (and they did!), they can certainly send a bomb on that today.

            Sat phones during the second gulf war (maybe even the first) became a liability. The transmission lit them up like a god damn beacon saying, "Bomb goes here!".

            • fragmede4 hours ago
              Triangulation, the math isn't the hard part. Where exactly on the continental United States are you proposing dropping ordinance? MOVE in 1985 was controversial even back then.

              Good luck if your mesh network is on 2.4/5/6ghz.

              It'll blend in with background radiation from home routers.

              • ssl-33 minutes ago
                It can have challenges, but triangulation can be done with signals that have recognizable patterns or features -- even in a sea of other co-channel noise sources.

                If you can observe the signal strength of your neighbor's home router while standing next to your own even if the signals differ in strength by some orders of magnitude (which is easy on Android; no idea bout iOS), then anyone else can also do the same.

            • bigfatkitten11 minutes ago
              Meshtastic uses naive flooding, which is fine for sparse networks (ie you and your three friends out hiking), but which doesn’t scale well at all.
