I tried the zerocoin feature.

1) Minted 1 zerocoin for 1.0001 ZOI. In this transaction. Second output is 0 ZOI but in raw transaction I see 1 "mint zerocoin" operation.

2) Spent that zerocoin for 1 ZOI. In this transaction. Has no input so I believe (?) it's completely disconnected from the previous mint operation:

3) I got ZOI to this address, never before used, brand new ZOI with no history:

Very cool. Are steps 1 2 really completely disconnected? Or is there some way to link them if you look deep enough?

@matejbilahora give me a zoin address? I will send you one 1 anonymous ZOI to test.
