Zcoin (XZC) is the first cryptocurrency to implement the Zerocoin protocol to ensure private transactions.

Zcoin was rebranded to Firo on November 30, 2020.

Firo Features

• Privacy-Enhancing Technology: Zerocoin Protocol. With Zcoin, the anonymity set is on a dramatically higher magnitude. Instead of having an anonymity set limited to the few dozen, Zcoin has an anonymity set that encompasses all minted coins in a particular RSA accumulator that can scale to many thousands and unlike other solutions is not subject to transaction graph analysis.
• Decentralized And Fair Security: MTP. MTP was created as a way to remedy the disparity between ordinary users and adversaries/cheaters where the latter could use botnets, GPU, FPGA and ASICS to gain a significant advantage and mount a cheaper attack.
• Incentivized Infrastructure: Znodes
