The name choice is unfortunate. I read it incorrectly the first time.

I read it correctly, but got a laugh after reading your comment. Maybe it could be marketable to two very different demographics

Same here. Imagining now bitch@ as the logo.

EDIT: Name aside, what an awesome project.

Earlier quoted context omitted.

Here's an article I found on Google that contains the claim about strikes associated with preventing civilian communication. Note the "physically high places." The story about the buckets fits within that frame. (My original source was an article I saw on HN; unfortunately Google's performance on search queries related to this subject is very poor, so it isn't easy to find again. I should have been saving them...) >…

I am not sure about your source. apart from blaming Israel with falsehoods such as organ theft, it has well known ties to Hamas https://ngo-monitor.org/wp-content/uploads/2023/12/Kahel-and... Here its founding team posing next to Hamas leader. Even if we take it in face value it does not show Israeli repression of Palestinian speech in Gaza, while Hamas has been regularly executing and torturing over speech

I saw other sources on Google, and a lot about Israel striking civilian telecom infrastructure (so many that the strikes on individuals were getting buried), so if you are interested in their approach you could look. There is a lot of "state department" pressure not to report the worst crimes, so unfortunately only headlines like "strike kills several sleeping families," which do not provoke a lot of public response at this point, are easy to find. To get information about the strategy that Israel is using to minimize international pressure, you need to be looking on the fourth pages of search results, unfortunately.

Anything with "bit" in (with the T pronounced) is a bit unfortunate for French speakers: https://context.reverso.net/translation/french-english/la+bi... .

Also anything with chat (chatte). Unfortunate or intentional..

This will be very interesting if they can conquer the distribution issue.

During the Hong Kong protests I recall several such solutions were created, but the dominant thing ended up being airdrop because it is what so many people already had locked and loaded.

This gives me the same vibe as OLPC. We had these places where people didn't even have electricity, running water, or public sanitation, yet some nerds at MIT thought (?) to themselves, "Hey, you know what these people need? Laptops!"

But even worse, you can install it from App Store or Google Play! Israeli territory or Israeli territory! What will these dipshits do next? Send the Palestinians some more pagers out of Budapest?

[flagged]

> instead of linking to the project page, the link goes to a propaganda website

It's detailing a specific use-case for decentralized communication

> The actual project is nowhere to be found

"Bitchat is a new messaging app that allows users to chat securely with or without internet access. Download it today via the App Store or Google Play store to begin communicating safely, even when connectivity disappears."

> Very woke tho.

When a genocide[1] is backed by major tech companies[2], its refreshing to know that alternatives exist :)

A lot of Meshcore/Meshtastic stations popping up lately too all over the world too. Repeaters/Router can, if you put a bit of love in to highly efficient 3.3V generation, forever an a 6V solar cell and a 18650 LiPo. I've tested 60km with a 868MHz LoRa station using a shabby 5dBi omni antenna. Just run out of hills to test more. But not as easy to use as BLE(+BLE Meshing) which is basically integrated into every smart…

I looked into Meshtastic a while ago and they use AES with no authentication tags. Also decryption happens on the LoRa device, which is a lot easier to crack with physical access compared to my phone. Even if you delete the messages it's still possible to decrypt sniffed LoRa traffic if, at some point in the future, one device gets captured. I'd rather the protocol gets updated so the crypto key can stay on the phone…

There's a few issues that have been brought to light in the last couple years at Hackfest and other events related to LoRaWAN / Meshtastic (and derivatives). I think most notably was the failure in entropy generated during the flashing process, detailed here - https://nvd.nist.gov/vuln/detail/CVE-2025-52464

I think we're a bit past the initial AES issues, at least the Meshtastic project promptly alerted people to their crypto issues and encouraged everyone to update firmware asap.

It's not too hard to use, as long as the hardware is flashed and ready. For the end user, it's an app that connects to a bluetooth connection. I think it would very trivial to have a few good LoRaWAN ops in the community, flashing nodes en masse and handing them out to peers.

Other than the cold start problem which isn't discussed (what's the userbase size in Gaza?), the main argument for Bitchat (or any other off-grid network such as Meshtastic, Briar, etc.) in Gaza when mainstream E2E encrypted messaging apps already exist and are widely used, is to not be dependent on Israel for cell service.

While I do really like the idea of off-grid networks in general but for this use case, is it really that hard for a state actor to jam Bluetooth (or all ~2.4GHz communication) on a large scale?
