You should be able to write a message and not rely on the recipient being available when you press send. You should also be able to run nodes to cache messages for longer, and opt in to holding messages for a greater time period. This would among other things allow couriers between disjoint groups of users.
this is prob the 100th time ive read about bitchat here, and the comments are largely the same (use briarchat, none of these really work that well, i dont like jack dorsey, etc) every time.
but this is interesting. and i agree strongly with this: "While this adds overheads, it's table stakes for real-life usage."
i suppose events like iran are really making me wonder if this stuff is possible it feels like anyone who's under the chokehold of regimes has completely run out of options, but even in America I'm getting the sweats wondering if there's going to be a time where such techs are needed. from what i gather none of these decentralized p2p messengers work well at all, but I also haven't truly tried. I can think of some moments that would've been viable test grounds though. Was at Outsidelands festival in San Fran and cell service was pretty much DOA due to the volume of people trying to hit the same tower(s). Even airtags which everyone in the group had on their beltloop weren't working.
And natural disasters like in Jamaica https://www.gadgets360.com/cryptocurrency/news/bitchat-becom...
The real obstacles here are political, not technical, as evidenced by the complete absence of any built-in solution that could be so useful in both everyday life (messaging a family member on the same plane when sitting separately, national park trips etc.) and emergencies.
We literally got smartphone-to-satellite comms now, but we're lacking the most barebones peer-to-peer functionality.
Also why would one want to have the data go over some servers thousands miles away when the device is right next to you? Seems like bluetooth is the perfect way to communicate for devices that are close to each other.

Why would that matter? Use Signal to protect the content, or use Cwtch to protect content and metadata. If you need to exchange secret communications that mustn't go through some server, why not discuss f2f with no phones around? You'd also eliminate attack vectors where your (chances are, Chinese Android) device spies on you, as well as anyone who has compromised it to read messages from screen.
Reliability? Why should we want to centralize things unnecessarily? It's nice as a fallback but then so too is P2P.
For me the cell phone without internet is almost useless, not much I can do on it, might as well sue a purpose built device. They're also very cheap.
Even better if Nextel still worked on phones (but without service).
Projects like this one are a step towards fixing that. Personally I choose to keep both street and topographical maps of the entire continent locally on my phone. There are plenty of uses for a computer without a WAN connection.
If I need to have all 4 members of the family meet me at the pool, first I need to go find each one of them. They could all be at different place. And then tell them individually to meet me at the pool? Is that the better solution you are proposing?
There was no signal in the remote Irish hostel so it was the perfect way to send messages covertly in the dormitory.
Fun night!
Oops! You (unintentionally?) make it sound like protests are illegal.

They're definitely effective when most of the country wants the government out, but by that point a vote would certainly do just as well, and with fewer flying bricks.
Voting does not allow to express that a certain issue is politically important to you.
Would that actually happen? No, but it's an interesting thought experiment
Like I said definitely not practical for messaging but I think something along these lines is how airtags work?
Doctors Without Borders feeding centers in a famine far from anywhere, searching for people in the rubble of a building following an earthquake, searching for people in a refugee camp, etc.
Verizon went down in the US this past week - perfect use case for Bitchat (or Meshtastic with a repeater or some other LoRa BT network). Verizon goes down while you're at the mall or store or Disneyland or whatever and you can still text to find each other.
300m max range with line of sight would cover something like when I go to visit my parents who live in a desert canyon with lousy mobile phone coverage, I can send a message that I'm at the gate and put the dogs in the garage.
Often one and the same since the first thing those in power try to do is make various activities by protestors illegal
- You want to check in with people around you about what to do - You want to check on the health of your family, from whom you were separated
I'd rather use Briar (https://briarproject.org/)
Please view my participation in this discussion as certified proof of the objective verification of my moral essence. I hereby claim superiority now and forever over JD and any such users of said technologies. Sincerely and respectfully, the undersigned.
>iOS doesn’t allow apps to fork subprocesses. While on the desktop Tor is running as a separate process, on iOS Tor is hacked to run as a thread inside the app itself. Therefore, you can’t have a system-wide Tor process like desktop and Android. If Tor is running in one app, and you open a different one, it’s not automagically going to start using Tor.

In both cases I think these may be characteristics of healthy judgment.
* I see LocalSend and LANDrop frequently suggested on HN but in my experience they rely on having a central Wifi router. No good.
* Android's QuickShare comes included by default, but it's buggy. Just yesterday it failed on me (I'm on an uncommunicated boat): it was defaulting to Bluetooth, so I had to reboot both phones to finally make it work over Wifi Direct. Not to speak about the "oh damn, you have an iPhone" scenario. Not ideal.
Anything else? (to remark: for airplane-like situations so no access to Internet and no central router)
Tbf, if my government would be out to kill me for protesting, I'd use something that at least was security audited. Not to shit on bitchat, I haven't audited the code personally.
Do we have evidence of this? The only concrete claim made in that post is that Briar 'hit 252 points on Hacker News," which is orthogonal to if it's actually being used.

Even without something fancy (e.g WiFi Direct, iptables on a rooted phone) you could have phones alternating between offering a network and promiscuously connecting to offered networks, then routing between these.
It's simple enough that I'd be surprised if nobody has done it, maybe because it's slow and power-hungry? I haven't tested setting up hotspots and switching networks from inside app logic, but afaik it's fine as long as you don't do both at the same time.
The story of using Bluetooth in a cruise ship to chat with family sounds like it’s pushing the limits of physics; communication in those conditions is highly unreliable. Most of our phones have onboard a class 2 device (the lower range, 10-20m), the real world has walls to reduce the range, and a cruise ship's metal structure creates a Faraday cage effect.
In case of protests, a jammer will silence all devices.
Anyway, I was thinking that in extreme cases we could modify our devices for communication at a community level—for example, creating a Wi-Fi mesh network with routers, or some other long-range protocol (e.g., LoRa).
Like, he quit BlueSky because he wanted it to be completely unmoderated which is, frankly, asinine. His view of what “censorship” means exists in a world along with spherical cows and no bad actors.
I think they just ran out of funding and died with a whimper.
A good mental exercise is to calculate how much you'd need to survive indefinitely in a pocket of rural America or the third world. No international travel. No bells and whistles. Limited cuisine. But survival and leisure unlimited.
When I've run the numbers for a comforable living, they've come to $300k (Vietnam, $12k/y) to $500k (West Virginia or Portugal $18k/y). But one could halve (or more) those figures by accepting standards of living our grandparents would have found adequate.
Then you make a choice. That world. Or the one you have. (Or something in between.)
Two-fifths of American households have a net worth over $300,000; more than half over $150,000 [1]. That means somewhere between a lot of and potentially most Americans have, on a global scale, fuck-you money. Just not fuck-you money to retain their status at the centre of the first world.
For countries with free healthcare, it is usually limited to people working there or citizens and ( in the German case ) recognised refugees.
We've had interesting mesh network experiments in the past (maybe some here remember Fonera), and some are trying on various bands, e.g. World Mobile, but none of these can realistically work unless prepared and deployed in advance, which happens through public choices, meaning public networks built to be truly resilient, rather than centrally controlled.
So, while technically interesting, they are not realistically usable in civil war situations. Instead, it's interesting to think about how vulnerable surveillance devices are in these situations, like modern connected cars and smartphones, which can operate a mesh centrally, for example, to guide and block cars at strategic road junctions and centrally acquire location data from the "meat-bots" carrying smart devices with them.
If I were a citizen in a civil war, I'd be afraid of the connected car and would stay far away from my smartphone if I decided to take action. If I were the ruler of a country that can't make its own cars and smart devices, I'd block them by any means necessary due to the serious national security risk they pose.
We need open hardware and FLOSS imposed by law, making it ILLEGAL to sell black boxes and fund research for verifiable hardware. Not to believe that the latest mesh app is good for anything without giving a single thought to real-world use.
