Yeah its fairly large and i have a feeling its going to get bigger and bigger /coin
so if you want to "anonymize" 1000 coins, you need to mint 1000 coins, and spend 1000 coins
Nah, the proofs stay the same size. Although, it looks like the parameters they chose may be totally insecure, at least if they're using the default ZRC lib. I think secure proof sizes were larger, around 128 KB with >3k bit keys, their proof sizes imply much smaller bit commitments. If this is the case the security is already broken.
