About Z Coin

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 original token for the Zerocoin protocol was called ZCoin, a project focused on blockchain privacy and anonymity. You can still see the original website through the web archive: zcoin.io, and the official Twitter handle was @zcoinofficial. This Solana token was created to pay homage to that early innovation in crypto privacy. When the original Zerocoin developer heard about the tribute, he acknowledged it and purchased the token himself.

This is a community-powered project focused on helping people understand what privacy truly means on public blockchains. We are not building new privacy tech or launching a privacy coin. Our aim is to create a space where users can learn why privacy matters, how it protects financial freedom, and what established solutions like Zcash and Firo already provide. We highlight the pioneers who built these systems and explain the real risks, tradeoffs, and benefits of blockchain privacy without hype.

A big part of that starts with understanding how visible you already are. Onchain activity reveals far more than most people expect on account-based systems like Solana and Ethereum. Anyone can review your entire history and see every action you took. Privacy spans multiple layers, from hiding amounts and counterparties to shielding asset type and network-level details, all while allowing the network to verify a valid transaction. By clarifying these fundamentals, the project encourages users to think more clearly about privacy and why it matters in an open ecosystem.

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.

Tracking

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

Privacy broken

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