Zcash is a cryptocurrency aimed at using cryptography to provide enhanced privacy for its users compared to other cryptocurrencies such as Bitcoin. The Zerocoin protocol was improved and transformed into the Zerocash system, which was then developed into the Zcash cryptocurrency in 2016. Development of protocol improvements and the reference implementation is led by the Zerocoin Electric Coin Company, colloquially referred to as Zcash Company. The founder and CEO of Zcash Company is Zooko Wilcox-O'Hearn. Its founding team includes cryptographer Matthew D. Green from Johns Hopkins University. Roger Ver was one of Zcash Company's initial investors.
