You don’t actually need to explain like I’m five. But, I saw a post on nostr from @lynaldencontact about (cashu)[https://cashu.space/], and I am not seeing what it does that’s easier/better than lightning. is it just custodial lightning?
Consider ecash tokens as gift cards for pre-coiners (those that still do not own a decent UTXO and cannot have enough sats to run a LN node for themselves). ecash = sats for poor fuckers
But you should NOT compare ecash with LN. Are two different things.

Nothing, it's a psyop

Private and offline transactions with easier UI/UX.

Please mention that those "transactions" are NOT bitcoin transactions. Are only trading digital gift cards.
The bitcoin transaction come in place ONLY when you redeem that gift card, over LN, to a real LN wallet / node.
Let's not confuse noobs with fancy terms, just for the sake of saying that ecash is Bitcoin.

I like the gift card analogy. I agree that ecash isn't bitcoin.
reply
ah ok, so a use case would be, I have some sort of award/reward system on my website, but my users are not bitcoiners, so I could ecash which would make it easier to onboard newbs, but they can still redeem for real sats when/if they are inclined.
reply
With an ecash wallet users can hold 100 sats without opening a channel or dealing with liquidity issues. I just sent corn from stacker news to my e-cash wallet via lightning, ecash isnt bitcoin but its pretty interoperable and will likely replace lightning as a medium of exchange.

That's nothing to do with ECash, same is true of SQL... custodial sats are custodial sats no matter how you authenticate to the server

This is retarded for a number of reasons:
  • If you're using Nostr for ECash you can use it for Lightning directly instead of LNURL
  • With ECash you're not actually transacting
  • When you go to actually redeem that ECash you're still incurring lightning routing fees and hops
  • Custodial providers have the same insights regardless of whether you use ECash or SQL- there's no privacy benefit to Bitcoin, quite the opposite as large mints create surveillance chokepoints on the network
