I hate to sound stupid but can someone please explain what cashu is? Is it like lightning payments? How is it different?
sending bitcoin over bluetooth between bitchat android and iphone. both have a native cashu ecash wallet built in.
the ecash travels directly from phone to phone. the sender needs no internet. like instant and untraceable digital cash.
it's going to be insane. work in progress with nostr:nprofile1q9n8wumn8ghj7enfd36x2u3wdehhxarj9emkjmn99ah8qatzx9ck5emrd4k8q6m909krsmtyddm8qdrnxpuxcue5096xxatcxekhjd3sxe6xwenc89u8gar4wsunqdmgxpa8xdekd3nk5aelvfex7ctyvdshxapaw3e82egpremhxue69uhkummnw3ez6ur4vgh8wetvd3hhyer9wghxuet59uqzqpy33h7rdjf70kmvcrtq7dlp2gh3cd4kf5l5ksjv2vkhck2law7928h6wz , nostr:nprofile1qyt8wumn8ghj7etyv4hzumn0wd68ytnvv9hxgtcpz9mhxue69uhkummnw3ezuamfdejj7qpqf742zec57c6qk9ajfr8wyjn0s4vrfzh4hesyj2yqplvj5wrfydxsdezp7p, nostr:nprofile1qyrkxmmjv93kcegpvemhxue69uhkv6tvw3jhytnwdaehgu3wwa5kuef0dec82c330fchxafn09engenjv9nkuvnpx4jnxmr8wcmrju35wfmhw6r5wvexvum9wfkxcdpsxf6h5u3nw9jkgercveekvenrw9e8x0mzwfhkzerrv9ehg0t5wf6k2qpqzqsu3ys4fragn2a5e3lgv69r4rwwhts2fserll402uzr3qeddxfs2gkl22 , nostr:nprofile1qyt8wumn8ghj7etyv4hzumn0wd68ytnvv9hxgtcppemhxue69uhkummn9ekx7mp0qqsvvlxnux5rm2jkelck7c6akt7mnmvkrycq9xx5wqd93e5wssycx3g7hxy6n , nostr:nprofile1qyd8wumn8ghj7un9d3shjtnndamx2un9d9nkutnpwpcz7qpqdvdcmtp5llrp63jdlmhspe9gffsyu9ew7cu3ld3f9y7k79nxzjxqtun7a8 et al.

It’s like a coin in a country fair that is redeemable for bitcoin; you have to trust the fair operators not to rug you, but you get high privacy because there is no KYC
On chain Bitcoin also has no KYC, and still isn't as private as Monero

It’s signed IoU vouchers
It's like lightning but worse
It's basically a vending machine. You send the mint Bitcoin, they give you ecash tokens.
Trading those tokens around is anonymous. There is no blockchain so the public can't see anything. There are no accounts so the mint doesn't know where the tokens came from. It can only know that the tokens are valid or not. Think of it like cash.
You can send and receive lightning payments, but you aren't directly interacting with the Lightning Network. The ecash mint is doing it on your behalf. But the user experience feels like you are doing it.
Remember that It's custodial (possible for a mint to rug it's users). Also the transaction level privacy is strong, but you still have to protect your network level privacy by using a VPN or Tor to hide your IP address from the mint.
