I decided I need to go back to my origins and get back to use xmonad in my setup. First things first, have to fix screen resolution using xrandr and .xprofile #HardcoreLinux #xmonad

Cashu eCash is bringing back true digital cash—private, bearer-based with instant transactions and built on Bitcoin & Lightning.

I’m really excited about what has been achieved so far and this whole exploration in general. In my latest post, I dive into what could happen if this system scales: competing mints, exchange rates, and even a Bitcoin-native credit market. No bailouts, just market forces at play.

Some of my takes might be controversial in the Bitcoin community, but these are conversations worth having.

To be fair, it doesn’t make much sense to run a single user mint just sending zaps is simpler as everything will boil down to that in this case.

The use case I see for eCash is to delegate the lightning node management (or whatever backing funds) - and the trust associated with it - while still maintaining privacy.

Tap-to-pay with CashuBTC ecash — for bitcoin.

Fiat credit cards nailed the UX: fast, offline, works anywhere.

I always wanted that for Bitcoin.

Now it’s open-source. Private. Instant. Beep, done.

In the video: two Cashu wallets for bitcoin.

Right: cashu.me (payer)

Ecash is sent directly via NFC — no internet, no delay. Beep, boop.

Ecash is a bearer token — the money lives on your device, not on a server. That’s why it pairs so well with NFC. Pick an amount, tap to send. No talking to servers. No syncing. Just push it over. The payment is pretty much instant. A PoS can accept ecash from any mint and receive payments via Lightning.

Still early days, but we’re experimenting. Card-to-phone works, but phone-to-phone? That’s the real killer use case.

Apple famously locks down the iPhone’s NFC chip — good monopolist.

F*k that. I found a workaround.

As long as one phone (ideally the PoS) is Android, you can send data both ways between iPhone and Android.

(You don’t really own your iPhone.)

Peace!

This is freaking awesome. The UX/UI improvements of this are massive. Question regarding offline payments, I don't see a way of guaranteeing no double spend.

Are you taking the approach that trust between customer/provider is required in this scenario? IMO, that's a total valid point. The service provider would swap the tokens as soon as it can to guarantee full ownership, right?
