It should be possible to have key rotation right? Something like changing your nsec every now and then.

What is the best bandwidth efficient Nostr Client?
I’m traveling and I’m looking for a client that is not as data intensive as Primal.

This is really helpful, thanks!
I guess the exchange of good could work if the merchant is online and the buyer can be offline right? The merchant can claim the ecash with the mint.
If the mint knows the IP of the person requesting ecash or redeeming ecash, wouldn't a mint be able to know how much an IP has minted? Or are mints dumb and not store this data? @nprofile…rt7g can you chime in?

This is super useful, thanks. Definitely cleared some things out. Some further questions.
So if I understand correctly, ecash is not technically a “file” in my hard drive, but a string in my hard drive, text. Basically containing the secret and the mint’s signature (after my wallet has decrypted the signature) and probably other data like the amount?
How is the receiver blinded exactly? I meant, the mint knows they are sending a signed blinded secret to a wallet. I’m guessing this information is encrypted too? Or how does the mint know where to send the ecash? Is it a randomly generated public key?
What does my wallet do with that string after it sends it to someone and it’s redeemed? Does my wallet get rid of it? How? ELI5
Also I want to know more about how the mint stays blind as to who is requesting the ecash or who’s redeeming ecash for lightning.
What’s the best wallet in your opinion? I’m using eNuts, but I’ve noticed cashu.me and minibits get updated more frequently with new features and improvements. It’s been months since the last eNuts update. So wondering if the other 2 are better?

@npub12rv…85vg I have a few Cashu questions I need to understand before I really grasp it.
1- The mint knows the amount but how do they not know my balance? Is it because of the nature of the secrets?
2- Can you explain how sending e-cash offline works? ELI5
3- On a practical level, how is the e-cash on my hard drive destroyed? Is it just deleted when the mint sees it for the first time?
4- Does the mint to who they are giving the e-cash to? I understand once you send the secret with the lightning payment hash, the mint signs the blinding factor and doesn’t see the secret inside, but how does it stay blind to who is requesting the mint?
I’m fascinated by ecash and want to learn as much as I can. I’m ready to consume the most amount of resources u can get my hands on.

Where can we get the stickers?

Yes I agree.
Plus, something happening to all 3 is very unlikely. So if something happens to the HW, there’s the seed + pass backup, and if something happens to the seed, there’s the HW to help you recover the seed.

Yo Marty, what are your thoughts about passphrase vs no passphrase?
Some argue passphrase is the way to go, others argue that passphrase is just a 2 of 2 with a single point of failure.
I’m trying to figure out what setup to incorporate. Any help is greatly appreciated

Jameson, what’s your advice in terms of using a passphrase with a Coldcard?
I got mine in the mail today, already setup a wallet but wondering if I should use a BIP-39 passphrase or not.
Any help is greatly appreciated.

Do you have a video about this. I’m about to buy a pre-built Umbrel and would love to have a similar setup

Been wanting to ask, how do you use Sparrow with the wifi off? Are you connected to your electrum server on your node?
