So cool! May be is a stupid question, how this would work if the receiver still needs internet to verify the funds? Does it make sense?
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.

If it's offline and off chain the apps can simply deduct everything strictly on the phones themselves in the wallets that you have stored on the phones within the app and then everything will sync up with the network once one or maybe both of the phones, but probably just one of the phones, it's the internet again.
