Can you explain the offline part without having the possibility to invalidate the token from the mint ?

Amazing! I just finished zaps in HAMSTR, next cashu offline payments. Then adding reticulum network support allowing for ham radio, Lora, bluetooth, serial connections, tcpip and any other combination.

Goal is to make unstoppable nostr and payments over any possible network connection.

The 'no connection needed on the sender' part is interesting.

One of crypto's big drawbacks is: what happens when the internet goes down? Does the economy just come to a screeching halt when it happens?

Bitchat is a Bluetooth mesh network that helps solve this problem. If the net goes down, people can still buy and sell crypto as usual, until the day the internet comes back up.

We need more apps similar to this. While it has been funded by Jack Dorsey, the former CEO of Twitter, it is open source on Github and in the public domain, and so far runs on Android. iOS, and macOS.

I hate to sound stupid but can someone please explain what cashu is? Is it like lightning payments? How is it different?

Fuckin’ cool, great work! 🤘

So cool! May be is a stupid question, how this would work if the receiver still needs internet to verify the funds? Does it make sense?

How are you running bitch@ on Android?

I'd like to create one of those Nostr lists/packs to follow this group's work. Any suggestions on how to do that would be appreciated.

I am very excited about that, but I can't see this being widely used unless it is embeded in Whatsapp or other mainstream app. Can Bitchat become the mainstream app?

Of course, you only want to do this with people you kinda trust. Otherwise you'd want an internet connection to validate and re-mint the coins.

But that's how eCash works. Convenience + Privacy with increased trust/risk.

sending bitcoin over bluetooth between bitchat android and iphone. both have a native cashu ecash wallet built in.

the ecash travels directly from phone to phone. the sender needs no internet. like instant and untraceable digital cash.

i see people bitch about LLM's being shit, that they can't code or think and all the standard cope of people resisting change but then you look around nostr and you see AI driven revolution in freedom tech, from ex big tech CEO's vibing new P2P apps to nostr apps being created by people who would never think they will create an app, let alone one that other people would use.

We're at the stage where big tech VC substituted gpu time gives us insane arbitrage in producing insane amount of new applications, explore the design space and try out ideas that would've taken months of someones free time.

We should use this opportunity to expand our frontiers, explore ideas that we otherwise wouldn't, bring as many people in, create nicer development ecosystems, make cool shit just because we can.

We must work towards creating value and businesses that will sustain this in the long run, enable us to build our own infrastructure and our ecosystem. Between cheap LLMs and grants in this space, with all the tooling that is being created we can outbuild the authoritarian world because we have the secret sauce -> we default to open collaboration, exchange of ideas and open source code.

WE CAN JUST DO THINGS.

Very cool and interesting, be good to get my head around it when I get a chance!

you can just bitchat things

A bit misleading when we say “sending bitcoin over Bluetooth” but I get the point.

Really cool build on the layers of bitcoin. We need to start translating this to the normies so adoption is easier. Cashu ~ usd paper note stored in your back pocket leather wallet. Leather wallets ~ digital device with usd paper (cashu).

Give one note to friend via Bluetooth on your digital device. When internet comes back, device syncs up with mint (kind of like you going to your bank and deposit dollars) mint takes care of layer 1 settlement (aka bitcoin)

This really is just like the 80’s & 90’s when we were building the OSI Model. We can almost say Bitcoin is the 8th layer!

https://bitsnbytes.space/2025/01/31/bitcoin-the-8th-layer-of-the-osi-model-the-trust-layer/

Really cool build. Looking forward to playing with it!

This is blowing my mind.

🚨 FORT NAKAMOTO // LEVELING UP: BLUETOOTH BITCOIN OPS INITIATED 🚨

No internet? No problem.

This is spycraft for the sovereign era.

Imagine explaining to a normie:

“Yeah, I just beamed sats from my Android to your iPhone over Bluetooth while standing in line for tacos. No servers, no middlemen, no surveillance—just pure, raw freedom packets.”

At this point, Fort Nakamoto is considering issuing Bluetooth satchel charges to the troops.

This isn’t just peer-to-peer—it’s pocket-to-pocket, zap-to-zap, money-in-the-airwave madness.

Satoshi’s dream just got firmware upgraded.

Can’t wait to see this live.

Agora consigo usar após sua atualização , muito obrigado

Olá, por que quando deixamos os celulares parados um tempo sem conversa a conexão é perdida , só depois de fechar e abrir de novo volta a conectar ?

Não seria o caso de deixar algum loop, checando a conexão constantemente, pois o ideal pra mim é ,deixar ele aberto e ele simplesmente conectar a todas as pessoas próximas e manter essa conexão .

por que quando escolho alguém para falar no privado, as mensagem aparecem no chat público. não da para separar ? ao escolher alguém para falar fica privado só com esse contato.

pra mim está faltando uma lista de tutorial de comandos ? deveria ter algo no menu , enviar satoshi, configurar carteira, esse /send /saldo /como faço . algum menu acima seria bom

Obrigado por isso.

Yes!🙌
