This is the new cache.
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.

i was just having this idea, if the cache was propagated all over by BLE then with bloom filters I think it would lower the reliance on connectivity.
