Perhaps nobody has noticed that the 6 badges of 0xchat have different POW difficulty levels.

Audits of the new NIP-44 encryption for DMs are up: "The fact that Cure53 was not able to identify any exploitable vulnerabilities can be
interpreted as a positive sign in regard to the security of the NIP44 specification and
implementations. "
But they did offer suggestions to harden the security that will be implemented soon and warned against naive implementations of secp256k1. π

A significant milestone achievement. π
107 more lines of code and noStrudel now supports https://github.com/greenart7c3/Amber
https://github.com/hzrd149/nostrudel/blob/next/src/services/amber-signer.ts
There are probably more important things to focus on but this is so much fun π

Changes are only in the alpha version https://next.nostrudel.ninja
Letβs go
Amazing. Thanks for adding Amber. You said it would come, but I didn't think this soon! π₯π₯π₯

#[0] iOS app has finally been successfully launched on the Apple App Store.
After 45 rounds of revisions and submissions, it took more than two months to finally be successfully launched.
This time, it successfully passed the Zap review and also added the App Pay donation function. We hope to get your support.
Zap Enjoy!β‘οΈβ‘οΈβ‘οΈ
All the difficulties felt like an abyss when experienced, but after the successful pass, everything is gone. Live in the present, and continue to build Nostr.

Congrats!
It took a bit to build but now all the pieces are there in the protocol:
- P2PK that allows you to mint ecash that only the owner of an npub can spend [1]
- DLEQ proofs that allow *anyone* to check if the ecash that is publicly posted is signed by the mint public keys [2]
With this, we could do the following:
- Alice posts something nice on nostr
- Carol has a nostr client with Cashu support. Carol takes 100 sats of ecash and locks it with P2PK to Alice's npub.
- Carol now has ecash locked to Alice and DLEQ proofs (it's all inside the ecash token).
- Carol zaps Alices nostr post by simply replying with the ecash (using a special nutzap kind)
- Alice sees that she received ecash that only she can spend.
- Dave, another nostr user sees Alice's post and Carol's ecash. Dave checks with the DLEQ proof if the ecash is valid and the P2PK lock is indeed Alice's npub. If so, Dave's client displays "100 sats zapped from Alice to Carol"
Is it possible to implement an anonymous zap, known only to Alice and Carol?
We use gift-wrapped DM & secret chat which can prevent metadata leaks.

Very good example, let me see how to implement it :)

hah, Nostriches keep me up
I'd love to see Amber login added to 0xchat. Do you think you'd be interested in adding it nostr:npub10td4yrp6cl9kmjp9x5yd7r8pm96a5j07lk5mtj2kw39qf8frpt8qm9x2wl ?

Yes, it's in the plans. But it will take some time, as integrating external signatures/decryption requires code restructuring for us, a massive task. π

Yes, the screen recording is from an iPhone, but this feature is supported by both iPhone and Android.
