Briar keeps Iran connected via Bluetooth and Wi-Fi when the internet goes dark(briarproject.org)

This should be a lesson for all of us. We should start building and maintaining lightweight mesh networks, just in case. We shouldn't take the world of cooperating ISPs and Meta and Cloudflare and Google and AWS for granted.

Is that the right threat model, though?

Governments usually switch off the internet when they have a risk of being overthrown. Thats' why it's happening in Iran. They want to disrupt the co-ordination of a coup, and their opponents only need to win in the short term after which it doesn't matter. In the US, the threat is censorship and tracking- suppression over the long term. Mesh networks are not great for that,because if you run a mesh network then you have declared yourself against the regime. Steganography may be better.

An amusing point is that secure steganography depends on redundancy with entropy- noise. A few years ago, it looked increasingly difficult because of lossy compression. Today, we're awash in randomly generated content, so it should be possible to make secure steganography quite high bandwidth. Although, it's not immediately obvious to me how to make use of it,because the randomness is the input to a diffusion model,not the output - you might need to run the model backwards to obtain your steganographic content. Which I guess is possible,although expensive.

There is concern that the US may also go from chronic concerns to acute ones. Opponents of the government accuse it of serious crimes, and are already perceiving violence used to suppress dissent. The administration is not popular and may lose a lot of power in the upcoming election.

It's hard to imagine that shutting down the entire Internet would be taken well even by their supporters, but the point of the exercise is to prepare for the unimaginable.

Keeping things in perspective, no, there is no reasonable concern of this happening in the US in the near term.

The places where this happens, like Iran now, are in extremely different situations than anything in the US, or any other Western country.

That shouldn’t discourage people running meshes though.

agnishom 1 hour ago|||
You raise a good point, and I think USians should do all of it: generally encrypt communication, try to conceal as much metadata as they can AND put up mesh networks. It is not the right threat model until it is.

That said, I never said that my comment was about the US.

There is Mesh(core|tastic) around. Both use LoRa.

With tiny solar repeater that placed on a strategic hill you can cover lots of kilometers. Being sensitive down to -145dBm opens a lot of doors.

I was able to build energy harvester nodes that fit into 5cm x 5cm x 4cm boxes that roughly cost around 20€. Without energy harvesting capability with a normal TI BQ wide range charge controllers (that stuff costs $1.5-2.5@pcs and eats every power source up to 18V! With pseudo-MPPT!) you can bring the entire thing down to <<15€. That's mass producable throw-away stuff.

Currently available LoRa-gear is either USB-power optimized (looking at you Heltec) or just awfully overpriced as soon as a solar panel is attached to it.

You also make yourself a bright shining beacon to anybody looking for a resistance network because Lora operates on very specific frequencies. It would be easy to spot you with an RF scanner.

But also because it seems fun in the meantime. In fact a state that doesn't plan to turn off the internet should probably want a cohort of amateur radio operators ready to turn into a signals corps.

Maybe in the battlefields of the future we'll be fighting with lorawan cyberdecks rescued from desk drawers, and meshtastic hackers will be the equivalent of fighter pilot aces.

On that topic, I'm in this thread hoping to hear about how anyone got into resilient mesh networks and what they're doing with them now (outside of overthrowing the Ayatollah).

Mafia has a vested interest in broadcast rights of football matches in Spain?

Spain blocks Cloudflare because the football league La Liga has a court order that allows them to point to IP ranges that are hosting/fronting live streams of football matches, and get ISPs to block access to those ranges.

If the sports league is influential enough to have a standing court order to be able to unilaterally block IP ranges for the entire country, I'd imagine that organized crime might take an interest.

Not to side track too much from this discussion, but I looked at that PolyMarket event: "US civil war before 2027?" Currently, it is priced at 91.3 USD cents for No. If you bet 100 USD, the payout for No will be 109.43. That is very good return -- ~9.5% for 12 months of lending (as PolyMarket required full payment at the time of trade). That is twice the (retail) risk free rate at the moment. I am actually tempted to buy a large part of the order book. Am I missing something obvious?

Also, if you enjoy troll humor, the comments section is very funny.

> Am I missing something obvious?

Considering reports like "Polymarket refuses to pay bets that US would 'invade' Venezuela" [1] one risk is poorly written small print, meaning you might not actually be betting on the thing you think you're betting on. This could also err in your favour, of course - but it's still a source of risk.

There's also the risks involved in cryptocurrency generally - it's the wild west, rife with scams, hacks, unexpected fees, and paperwork.

And thirdly, prediction markets often lack market depth, so if you want to invest a non-trivial amount the price can move a lot. You want to gamble $2,000 to win $190? No problem. You want to gamble $200,000 maybe no-one will take your bet. Can you be bothered to go through all the KYC paperwork rigmarole for $190 ?

802.11s with BATMAN routing works very well - you can have commercial quality links with tons of nodes.

All Semtech LoRa modems are wide-range modems. You can switch to basically every other frequency.

An idea would be to move to SX128x modems with work around 2.4GHz. You recycle Wifi-gear for directional stuff. This also enabled you to hide below Wifi traffic.

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 peddling/colporting (look up the term in French) cassettes with the software.

Please, sell me a USB-C device that gives me mesh networking on my phone.

I'd like a Small, Medium, and Large option. Ideally, each would have a passthrough charger, so I can charge my phone even with the device plugged in to my phone.

The Small is just the device, and I guess it would drain my phone's battery. The Large would have a 25,000mAh and be just small enough to legally take on an airplane in the United Stated. The Medium has a smallish battery, maybe?

Give me what you can. Wifi. FRS. CB. LoRa. The ability to switch between those? The ability to broadcast across all of those in some spread-spectrum broadcast?

Make me use your special App that I have to install on my phone.

Make the device also act like a storage device. The Small has usb storage big enough to store the APK for the app for me to side-load.

The Large has enough usb storage for, I dunno, all of Wikipedia and medical texts, and open maps, and a few other things, and the Kiwix app to side-load.

Make the Medium and the Large also be able to be a hotspot, for other people nearby to be able to connect to, so they can download the app and browse Kiwix, and send messages through my phone? Or just let my phone be that hotspot, I guess?

And most importantly, give me messaging. Secure point-to-point, exchanging keys by touching our phones together, or using QR codes, or something.

Or broadcast messaging. With configurable repeating.

And then make the Base Station version of this, which has solar panels, and a battery, and it's just a repeater. You install and forget.

If you're only going to build one thing, build the Small version I described. Next, I guess, would be the Base Station. Next would be the Large.

Where is the Kickstarter? I'll back it right now. I'll buy 2 Large, 6 Small, and 4 Base Stations. Right now.

Pragmatically, cost and ease of access is especially important in suppressed countries or ones with unstable infrastructure. While the devices you're talking about has lots of conveniences, distribution and price dominate in lower income regions.

For a side project, sure. But in first world countries, the odds of infrastructure breakdown or suppression of Internet is incredibly rare. In Iran's case, suppression is a weapon so phone only makes a lot of sense.

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?

cookiengineer 10 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.

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!

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.

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

You can just airdrop iOS apps to people. I don’t think the recipient needs network connectivity to receive it.

Source? I guess you're thinking of long tap → Airdrop, but that essentially shares a link to the Appstore via Airdrop. You're not transfering the app itself.

I tried to set up Briar recently so my partner and I could text on the plane. We tried everything including manual exchange of the special links and QR code pairing and nothing worked. This was even while we still bad ground internet access.
