Zcash is a new cryptocurrency that launched on Friday, October 28, 2016. A clone of Bitcoin forked from the Bitcoin codebase 0.11, Zcash is differentiated from Bitcoin and Ethereum by the added functionality of completely private transactions. For that reason, Zcash has been hailed as “untraceable”.
To allow private transactions, Zcash employs a technology from a branch of cryptography and computer science called zero-knowledge proofs.
