Private financial transactions,
enabled by the Zerocoin Protocol


Why does Bitcoin have a privacy problem?

Bitcoin Network

In order to solve the “double spending problem”, all transactions on Bitcoin must be stored on a public ledger.


Notable studies have shown that the same techniques used to analyze social network topology can be used to analyze Bitcoin.

Privacy broken

Anyone can use the public ledger to break privacy, including powerful corporations and institutions such as the NSA.

How does Zcoin improve privacy of the Bitcoin Protocol?


With Zcoin’s Zerocoin Technology, you can “mint” a coin found on the public ledger into a private coin, breaking any transactional links and ensuring complete privacy


Zcoin has integrated Tor to hide your IP address. Dandelion further conceals the IP address when broadcasting a transaction on the network


MTP stands for Merkle Tree Proof. It is Zcoin’s unique Proof-of-Work algorithm with a focus on ASIC-resistance and egalitarian mining for all participants



Did you know?

Zcoin is the first full implementation of the Zerocoin Protocol, which allows users to have complete privacy via Zero-Knowledge cryptographic proofs. It is worth noting that Zcoin is unrelated to other cryptocurrencies utilizing the Zerocash Protocol. Although Zerocash is a development from Zerocoin, their respective implementations are not simple forks of each other, but rely on different cryptographic assumptions with various tradeoffs. Both approaches supplement each other quite nicely, and a good way to describe them would be sibling projects.

The Zerocoin Protocol is being actively researched and improved, such as by a new extension that when implemented would hide transactions and address balances.
