Hi Nostr!

I am new here and I’ll be sharing all things Pilates as that is what I’m most passionate about. Looking forward to meeting lots of you.

More will be revealed 😉

Why not simply posting notes on nostr?

Bittr is going Nostr! Happy to finally be here. Looking forward to pure signal and less noise 😏

STAY HUMBLE AND STACK SATS.

Hello and welcome to nostr, glad you’re here 😊 Once you get the hang of that app, test Nostr on one of the other awesome platforms. Personally for social media I like Damus on my phone, but I use either nostrudel or primal on my laptop. If you wonder what is available to play with, check out Karnage the Kat’s website over at nostrapps.com. Either way just have fun on the freedoms protocol

Amethyst, got it down to only crashing 9x per day, which I can live with

What's your daily driver in terms of nostr client(s)?

Yes, the merchant online would immediately "redeem" the token to find out that its valid and be issued "his own" token or cashed out to lightning.

I think the IP data is a trust thing. The redeemer needs to visit the mint to redeem, so there has to be IP. The mint doesn't have to keep this info, and doesn't have to give this info to authorities, but it ends up being a trust issue.

The cashu model is a trust model anyway. You could get rugged if you don't know your mint operator.

One way I could see adoption is if this is just a noob lightning multiplier. ie: lightning is used/adopted worldwide and not everyone can manage a lightning node. Custodial (WoS) works, but what if Uncle Jim runs a node for the extended family. I would trust Uncle Jim more than rando internet company not to rug me. This exists in a custodial world.

Then the privacy benefits of ecash, along with all the offline stuff that can be done, would push cashu into the mainstream. Like a hundred cashu notes are minted. Passed around millions of times, accepted as currency, never having to touch the mint until they are "cashed out."

I sent you a DM with an ecash token to show what it is.

The mint knows the IP address of the redeemer, from what I gather, so there could be some log privacy leaks. outside of that, the mint just adds a signature when only the amount is visible to it.

In this case, there really is no "recipient," like when the Treasury prints a dollar, anyone can "redeem" it wherever it is accepted. In this case, it needs to go through a specific mint. So you can think about it like a "state" bank issuing their own currency in the 1800s in the US. The bank issues a note (IOU) redeemable for something (gold) that can only be traded for gold if brought back through the bank. They would check to see its not a forgery first, then issue the gold. This is a digital blinded transaction, so the mint doesn't see the user bringing it in for mint or melt.

You can also send a token P2PK, where the token is locked to a users private key. Instead of DM, I tried to send you a token on this note locked to your private key, but i couldn't get it to work. In that case, there is not a recipient per se, but you would need to know the private key of the pubkey its locked to to redeem this token.

Where does it go?

Unless its locked to a pubkey, its a race to the mint with the token. So if I sent you a token in this note, anyone reading it could redeem it. I could even redeem it back if I made it to the mint first. Its like a check that you could cancel. So I create a token from my wallet, text it to you. If someone looks over your shoulder and writes down the token, they could go redeem it. I could also give you a token, you give me a coffee, then I could walk out and redeem my own token. So the exchange of goods should not be done "offline," unless its locked to your private key. You should only give me my coffee when the mint has "redeemed" this token. But to answer the question, lets say I text you 100 sats. You redeem it. Then tomorrow I check my text messages, and the token is still there. Its worthless, but the string of text is still there.

I run a local cashu.me and the PWA version of that will be my favorite when the camera works to scan lightning invoices. Its fast, has all the features, and I like that its on my server as a PWA.

Right now I use eNuts, but ill switch when the camera works.

Calle or someone else can probably answer the questions better about how exactly the process works. I just know the basics.

The cast iron vs stainless steel pan debate is dumb.

Titanium is the new hotness.

1. They blindly sign a transaction of an amount. They know they signed 1000 sats, don’t know the parties.

2. If you have an ecash token the mint has already signed it, so it’s just a string that you can send in a text or print out and hand to someone offline. Like a dollar bill, it’s an iou but for sats.

The recipient can hold the iou offline but to convert to lightning sats he would have to be online to have the mint verify and send the lightning transaction.

3. When you send sats to the mint and “mint” ecash the mint blindly signs it. The mint is not involved after that unless and until someone brings a token to “melt,” where the mint checks that this is a valid signature and that it hasn’t been redeemed before, then if so, then it melts/mints a fresh token for the user or sends a lightning transaction. So the token doesn’t have to be deleted, it can be saved, but it’s a worthless iou after it’s spent.

4. The blind signature is the mint just knows the amount. When it checks for validity it just needs a valid unused signature to redeem. It doesn’t care to or from whom the token comes.

** these answers may all be wrong, Calle will straighten me out. But I gave it a shot
