i finally penetrated the waffle of ecash today
they have a problem of metadata correlation
it can be mitigated by multiple denominations being shared around by users, probably
i had this idea of a UTXO scheme that had fixed, unbreakable UTXO denominations about 5 years ago
if you can trade a 20 for 2x10 with randoms without risking getting invalids, then you have a scheme
but, to be very very fucking crystal clear
ecash without this change trading scheme has a serious metadata tracing vulnerability
