In terms of metaphors for #cashu nostr:npub1dx5q2el8nd4eh3eg9t2e25fd7zuqg7zxz6ldkc3uzgh66ss2yc6st288sj , this is what I’m thinking (out loud) for newbs.

In terms of privacy it’s like when you go to the atm to withdraw cash, the bank can see how much cash you withdrew (in this case lighting) but not where you are spending the cash (your cashu mint tokens). Should you need to put cash (mint tokens) back into your account, you can deposit cash back to your account via the atm (withdraw tokens to lightning and send out to lightning wallet).

So cashu has great privacy benefits even over and above lightning and is ideal for a community P2P system. I love it

You have a balance of 500 in there? Don’t forget you probably need to leave room for fees. Try sending a slightly smaller amount.

Yep. Cashu and the like is how we onboard 8bn people and enable bitcoin to become a medium of exchange.

Bullish on Cashu/eNuts

I like the circus or fair analogy. The person in the booth giving out ride tokens has blacked out glass, so they can't see who is exchanging cash for tokens.

What's cashu and enuts? Does it have anything to do with LN?

I have a LN node, is there stuff I can do with cashu/enuts on there?

Checkout the section on how to create a Cashu Mint.

nostr:npub1dx5q2el8nd4eh3eg9t2e25fd7zuqg7zxz6ldkc3uzgh66ss2yc6st288sj is a Cashu wallet for android and iOS

Questions nostr:npub1dx5q2el8nd4eh3eg9t2e25fd7zuqg7zxz6ldkc3uzgh66ss2yc6st288sj - does someone via the nostr contact list need to have a cashu mint/wallet to accept eCash?

Some Nostr client allow to redeem Ecash and send it to your Lightning wallet. A cashu wallet is needed if you want to send ecash yourself or redeem it without cashing out immediatly to LN. By redeeming the first token on eNuts (without having a mint) it will ask to add the mint of the token that is incoming. If you agree, you redeem it and have the mint associated to it in your list (from which you can cash out back to LN anytime)

Pretty sweet. I'll have to check this out.

Still trying to figure out automatical rebalancing and stuff on my Raspiblitz. I'm not a tech guy, but I've seen LN bits on there.

very interesting concept

when you spend cashu mint tokens, someone has to receive the same amount of tokens, correct? how does the cashu protocol move these tokens around the network with no logging?

curious with the protocol tho

It’s not like keys that unlock the Bitcoin/sats, the tokens themselves ARE the currency. I believe it’s the pool of sats as the “entrance fee” to the walled garden transferable 1:1 sats to equal parts cashu tokens. You pay a lightning invoice of 500sats, you get the equivalent cashu tokens, and everyone else does the same. I’m trying to draw metaphors here to simplify for newbs without missing critical protocol components and oversimplify. I’m not 100% clear on the technical part of the moving tokens with no logging other than there’s perfect harmony between sats entering and cashu tokens created.

nostr:npub1dx5q2el8nd4eh3eg9t2e25fd7zuqg7zxz6ldkc3uzgh66ss2yc6st288sj and nostr:npub12rv5lskctqxxs2c8rf2zlzc7xx3qpvzs3w4etgemauy9thegr43sf485vg are good resources for all things #cashu
