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.

But we won't, because those are hard to maintain versus the convenience of letting providers do it for us, hence why we keep getting suckered into handing over control to these centralized powers.

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. 1: https://polymarket.com…

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…

> 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 ?

If there is really a civil war, won't these frequencies just get jammed?

Jamming is a double-edged sword, there are common frequency bands used by everyones equipment like 2.4GHz, 5GHz or the ISM band. If you jam those indiscriminately, your own stuff stops working as well.

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

The problem is transmitter power, residential Wifi radios are limited to a very low transmit power, like 0.1W, if you do more than that, you're breaking the law, and you're very easy to find if they come looking.

Earlier quoted context omitted.

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.

Why would anti-fascists jam EMS frequencies?

If you haven't been paying attention to American politics, there are currently widespread protests due to a woman being shot by ICE last week. It looks like the current administration may be seeking violent unrest in the hopes of delaying elections.

> looks like the current administration may be seeking violent unrest in the hopes of delaying elections Civil war requires two militaries. Tiananmen Square wasn’t a civil war.

Not wrong, but don't forget there are many militias with itchy trigger fingers all over the political spectrum here, though admittedly some parties have more affiliated with them than others. It's not a stretch to assume should fighting in the streets escalate beyond ICE shenanigans that larger armies would not quickly congeal from the pocket groups and individuals.

Is this actually true? Is anyone in Iran using Briar?

I would be very surprised if they were. Bluetooth's range is far too limited for this to be useful or to make a workable mesh. Seems like the GPG of comms.

Yeah, the problem with these mesh networks is that for them to work, you need high transmit powers typically not found in off the shelf stuf (because it would be illegal).

A would-be opressor can just have a van full of antennas drive through the neighborhood and triangulate all those transmitters, after which you'll get caught.

It's like using high-powered flashlights to covertly message each other.

Isn't this borderline false advertising?

The title implies that this is instrumenta in evading the govt block and monitoring on messaging.

The truth is it's not being actively used, and this is just a proposal, and might not be that practical or safe to use when the bad guys come looking.

Given the recent threats from Cloudflare against Italy and siding with Vance, Musk and co., this is definitely not a far-fetched reality. Big Tech has demonstrated which side they are going with.
