The concept of open-pleb by @gandlaf21 is amazing (still WIP). It's a marketplace to match (1) a seller who has bitcoin but would like to pay a fiat QR code and (2) a buyer who has fiat and would like to stack non-KYC Bitcoin. (1) seller walks into a store, chooses goods and has the option to pay via QR code (could be alipay or a million other payment systems globally). They put up an equivalent amount of ecash with a coordinator who then starts looking for someone on the other side. (2) gets a notification and opens app to see there's a QR code waiting to paid. They pay the QR code and provide a proof to the coordinator. If both users agree that the payment has taken place, the coordinator sends (1) the sats that (2) has put up. If this works this is IMO the best way for stacking Bitcoin. No exchanges, just two regular people with two separate wants that meet each other on the internet.

That's impressive if the volumes get high enough to not cause friction and/or inability to match people. Excellent concept. Top marks for Gandalf.

It's possible to be done with Robosats nowadays but clearly it's not obvious, so nobody is aware of it. I think the only thing missing to make things easier is allowing the Robot to use blossom servers to upload pictures or the QR itself. Nice feature to work on 😁

Proxy merchants are the way.

If the user gets a notification and would otherwise just approve the transaction based on their current balance and maybe WoT conditions or anything else that can be written in code then this can be automated and the latency becomes negligible. Anyone running a Lightning node already has an online wallet and could add this setup.

yes speed is crucial for this ux to be decent. my hope is that at some point there will be automated taker bots, that will take and pay offers, then upload receipt automatically. will only work to the degree that a fiat provider is automatable though...

I'm a robosats user myself, and the main problem I encountered for making it work for this usecase is speed, and streamlining the experience from scanning the merchant QR to the point where the taker makes the payment. By using cashu/custody, we can take out a lot of the variables that LN might have, and do all the clearing inside the mint. It's separating withdrawal from the actual orders, basically reducing the steps and shrinking the time needed for a payment to the merchant to complete. I think payment speed is crucial when paying a merchant, so that is what openpleb will focus on.

It's almost similar to #Bitzon on #Telegram... It works with Amazon orders only and you can choose the premium fee you would save on the buy... The other side pay cash and you will receive the order🎩⚡
