Zcoin utilizes the Zerocoin protocol to provide anonymous transactions in a unique scalable way. The protocol, originally intended to be an extension of Bitcoin, allows you to send coins with no transaction history. Bitcoin records the history of every transaction on a public ledger for anyone to see. Wallet addresses are only pseudo-anonymous with the potential for people to link your identity to an address. However, with Zcoin, you can preserve the fungibility and privacy of your spending.
