Yep, nothing gets me salivating as much as the idea of a digital Euro issued by the EU, implemented to be fully private (can't see sender/receiver/transaction count/transaction amounts), bulletproofs [0], combined with view keys that are single-use only when the law needs to intervene. Zero-knowledge proofs used to determine if I paid my taxes without knowing how much I earn and similar exotic behavior.
Was quite surprised something like this is possible and I love seeing new crypto tech on HN.
Well, I wouldn't mind a centralized and fully private crypto authorized by EU. They can authorize private construction of digital Euro wallets, so that only I know the key, but require me to give them a single-use view key if law demands it.
