the ins and outs of a cashu or other ecash mint are inherently revealed to the mint via IP addresses, you can only have proper ecash anonymity with the use of an anonymising proxy
quotingso, i correctly understood it... the mint can track the size of the token to the input and output IP addresses

that is kinda important information for users of these things, isn't it?
it means you can't have anon ecash without having a tor proxy or similar
