Why does BLOCKCHAIN have a privacy problem?

Blockchain

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

Tracking

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

Privacy broken

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

How does Zcoin ADD PRIVACY TO THE BLOCKCHAIN?

Anonymize


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

Tor/Dandelion


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

MTP


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 Sigma 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 Zcoin’s old protocol 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.
