Zcoin ( XZC )
Zcoin has implemented the Zerocoin Protocol, one of the most groundbreaking academic developments in Bitcoin research. The Zerocoin Protocol uses Zero-Knowledge proofs to guarantee complete financial privacy and anonymity. With Zcoin, the anonymity set is on a dramatically higher magnitude. Instead of having an anonymity set limited to the few hundreds, Zcoin has an anonymity set that encompasses all “minted coins” in the Zcoin system.
