IP level privacy is something we can't fully address in Cashu: Tor would be best but doesn't work in browsers. VPNs are great but the user needs to get one by themselves. OHTTP is a good compromise which we're adding. The best part about ecash however is that as the payer / customer in the vast majority of cases you remain fully offline when you make the payment. The merchant needs to talk to the mint (can use Tor, VPN, OHTTP) but the vast majority (customers) don't talk to the mint while making a payment. View quoted note →

If I had some free time, I would build a service that facilitates atomic swaps of ecash from one mint to another. Something like a broker, let's call him Charlie. - Users Alice use mint A, Bob uses mint B - Bob wants to pay Alice but doesn't have ecash from mint A - Bob discovers that Charlie holds a balance on mint A and mint B - Charlie offers to swap from B to A for a 0.5% fee - Bob agrees, atomically swaps coins from B for coins form A - Bob sends Alice coins from A Charlie obviously announces himself, the mints he supports, and his contractual conditions, on Nostr. That's also how Bob discovers him.

cashu is a protocol with crazy adoption but no company.

we like it when the mint doesn't know. here: atomic swap of cashu token with a lightning payment provided by a third party lightning gateway. as long as htlc's are supported, the mint can't prevent it. you can't do this with any other custodial system.

gm, people of the free internet

we’ve been cooking. the upcoming redesign of cashu .me wallet is beautiful. the smoothest onboarding for new new bitcoin users. open in browser, add to home screen, receive ecash. no app stores, no permission.

the cashu mint auditor has made over 40k lightning payments. the average time for a payment was 5.2 seconds. audit.8333.space
