Cashu -- ecash+BTC/LN combo -- is a great idea.
As I see, it combines the drawbacks of
- self-custody solutions (you can lose your funds)
- custodian solutions (they can rug you)
:))) Still, it's a great idea!

I don't care about how many (or few) followers I have, but I like Coracle, because it shows slightly higher count than other clients :)
A cashless society is a surveillance society
90% of my Rust compile errors are fixed by prepending a '&' before an expression.
9% is removing a '&'.
1% is others -- like prepending a '*'.

Use cash, while you can!
Use cash instead of electronic methods (where Bitcoin payment is not available).
Good old, proven, tangible, more-difficult-to-trace, smelly banknotes and coins.
CDBCs will ultimately kill cash.
I'd like to be considered for bounty 😎

It's quite complete, but I can continue working on it
There is a Nostr NIP proposal for key invalidation, using a chain of pre-generated keys, so a key can be rotated safely to another one (cannot be faked)
https://github.com/nostr-protocol/nips/pull/158
While working on a proto implementation, I got an idea how the crypto part of it could be somewhat simplified by using only BIP32-style key derivation. Stay tuned :)
Work-in-progress:

I suspect an issue with the scheme in the NIP:
key addition is performed on the secret key at generation, but at verification on the public key. The two just don't add up.
I've left a review comment on the Nip-41 PR.

What's a good source for Nostr stats?
No. of pubkeys, events, relays, etc.
Which Bitcoin/Lightning wallet on F-DROID to recommend to a first-user?
I had a look and was a bit disappointed by the selection (or lack of). The only familiar name I saw is Simple Bitcoin Wallet (SBW), but AFAIK it is no longer maintained (for 1+ yr).
With the simplicity of Nostr protocol, and the good library support, writing a simple crawler from scratch is so easy! Coding pleasure.

There's no second best Bitcoin.
But is there a second best L2?

Nostr Delegation (nip-26) and Nostr Connect (aka Signer nip-46) solve a very similar problem: interacting safely with Nostr, while your secret key is kept in a secure app.
The Signer way is suitable for occasional signing, while delegated apps can work fully on their own.
The beautiful thing is that you can create a Delegation using a Signer!
Is there a chat/channel for Nip26/46 related dev?
Is there a general Nostr dev chat/channel somewhere?

Nostr Connect (NIP-46) is a clean&nice protocol, rather easy to implement.
Here is my demo, based on @yukibtc's sample
