"I'll send you nuts" It's so easy to pay back someone for offering you a drink now. Just send nuts in chat.

GMs :)

There are currently two notes who take the cake for the most PoW with 17 bits of leading zeros. Can anybody top that?

Experimental merchant PoS app that is able to request ecash from Satocash smartcards. In the video you see: 1) (merchant) inputs the amount in sats 2) scan the card + insert pin 3) receive ecash and generate a new cashu token that can be imported into your wallet of choice 4) (Hidden) the change is automagically re-imported into the card.

The most based GrapheneOS feature is "duress PIN", which is a PIN code you can insert anywhere the actual PIN code is required and completely wipes the device. It makes the police very mad.

Since some time now we have protocol specifications for authentication that can "gate" a Mint to a set of registered (and maybe KYC'd) users with OAuth 2.0. Users receive an OAuth JWT token on registration that they can use to mint BATs (blind authentication tokens). The latter are just ecash, but for requesting access to the Mint API. So even if the users are KYCd, their privacy can be preserved amongst all of the registered users (Mint doesn't who amongst the registered users is using the service). This is Cashu's way of providing tools to the Mint runners for meeting the regulators at a middle ground, and the most we can do. Any requirement beyond this is tyranny that must be fought in the "shadows" like you said.
