Building https://npub.cash 🥜 Working on awesome nostr, cashu and Lightning stuff 💜⚡️

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 🥹

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

Yes. But it's not just the relay list, the `pzap` (encrypted zap content afaik) is rather big, also for short zap comments (maybe because of the padding?)

https://sourcegraph.com/github.com/vitorpamplona/amethyst/-/blob/quartz/src/main/java/com/vitorpamplona/quartz/events/LnZapRequestEvent.kt?L192

That’s not part of the spec afaik

We have to reduce the byte size of zaps. Some zaps are just too big and are several KB of data (without the user even providing a comment) which causes problems.

zap space is limited!

Bro we need a simple "donate ecash" web thingy that anyone can add to their website, how is it even possible we don't have that yet?!?

Let a bro cook, okay?!

With cashu and nostr you can build a privacy preserving Lightning donation component for your static webpage without operating a backend or signing up for a service.

🤯

Or even better: Post on nostr about posting on nostr and getting zapped to buy coffee, then get zapped for it and buy coffee 🧡 nostr:note1pwlkmc86zzqu936atpn47ee04hqjvy8werjr75f4x85x9ztuzsjq2f28v6

Post on nostr -> get zapped -> go to the café up the street -> pay your espresso in Bitcoin

🤯

Madeira does not stop to amaze me 🛳️⛰️🌈

I wish I could stay here forever ⛰️🧡

Cashu has a new homepage 🔥

https://cashu.space/

I tried nostr:npub1eaz6dwsnvwkha5sn5puwwyxjgy26uusundrm684lg3vw4ma5c2jsqarcgz for the first time yesterday, because I had to fix some stuff in the npub.cash zap provider... this is aboslutely amazing!

Maybe I will do some Madeira QnA / live coding next week! ⚡ 💜

Is there a tool to verify zap receipt events with?

Yep, but with your trusted Nostr keys.

We could add a PGP key and to our profile events and use the existing tools to add signatures. verification would still need to be solved though.

We could also simply schnorr sign a hash of the email with our nsecs

Or we don’t email and use NIP17 instead 😁

What if we start sending nostr: URIs in the end of our emails with a signed copy of the message and a little extension verifies the Nostr signature in the email and replaces the unsecured email text with the signed one without even pinging any relay? 🤔

Isn’t that basically PGP with extra steps?

Man I hate dynamic imports... As if JS was not already hard enough to structure well...

Are you coming? 😁

Hey relay operators 🫡

What should I building client side assume to be a reasonable max length for an event?

#asknostr

I am convinced that Madeira is too beautiful to not be fake by now…

utxo the webmaster 🧑‍💻

If algorithms weren't useful, nostr would be the #1 network and tiktok would be stuck at 20,000 users

I don’t think TikTok should be our role model

Madeira is surreal ⛰️
