Oddbean new post about login | logout What we'll be focussing on for Cashu in the coming months: - bolt12 - websockets - blind auth - fees - keyset rotations - on chain - payment requests - wallet sync - any-amount ecash - cdk mobile app - mintd - external mint signer - HTLC swaps Most of these are already started projects and many are almost there but need more adoption. Lots to work on!
- multinut
Any amount meaning any denomination in a single proof??? That’d be very useful
Yes. It's the most exciting thing on that list and a huge thing.
how will that work with the mint's keysets?? very curious about it
One option are keyed-verification anonymous credentials like used in WabiSabi. There's one implementation by nostr:nprofile1qqsfuv8fgq3cek0ta0rr9qtkm4x3pxqjz22y9u4xcwrj0lrxlfl2jzspz4mhxue69uhhyetvv9ujuerpd46hxtnfduhszrnhwden5te0dehhxtnvdakz7qgswaehxw309ahx7um5wghx6mmd9uv87spp: https://github.com/lontivero/cashabi
Yup, the any-amount ecash will be based on KVAC also used in WabiSabi and Signal! The mint only needs a single private key, and the entire wallet can be stored in just a single nut. All that while also vastly improving privacy (blinded amounts, like confidential transactions). It's going to be so fucking beautiful 🥹

It's easily the biggest change in Cashu we ever attempted but it's worth it.
Is the WabiSabi Whitepaper the best Place to learn about KVAC? I found the sand & envelope metaphor pretty entertaining, but I’d like to go a bit more in depth
WabiSabi paper section 6 🤙
Yeah, I got that working a few months ago, but was told it was a bad idea. What changed?
You got what working? I don't believe that.
Yeah. ‘Working’ might be a generous description, but I implemented several working methods - like keyforamount, swapforamount, mint/bolt11foramount. I stopped when I was told it was a bad idea, but it greatly simplified the proof management and payment. I hacked it all in nutshell Cashu mint. Proof of work is in this branch below. Bottom line, I was successful in deriving the public/private key for any arbitrary amount and issuing the promises. https://github.com/trbouma/cashu/tree/amount_key
Yeah but that's the easy mode with broken privacy.
I was just proving the math worked. Didn’t get as far as working on privacy implications. Could easily be addressed by a wallet by breaking an amount into the sum of two random components, etc. Anyway, very keen to see this idea is still alive.
Cashu -> On chain it'd be very usuful for privacy too
I just nutted
As a web dev, where can I contribute?
Oh you can! Cashu.me is a wallet based on quasar, Vue, pinia, desperately looking for contributors. We also need help with our docs etc. Let's talk, you can DM me on matrix or nip17 me if you like.
let's get cooking nostr:note1l2z7c6w8wrs6se585l4p9x4uqpn49gqjaer4hnrfrsaed0vhkvnsynlhsx
will you get rid of the feature that makes it centralized garbage? or is that like core to the protocol?
Would like to send you some ecash for and experimentation
Love to see it
