Zcash is a decentralized cryptocurrency that utilizes zero-knowledge proof cryptography to protect the privacy of transactions. It was founded in 2016 by a team of top cryptographers and is based on strong scientific research. Unlike Bitcoin, Zcash transactions automatically hide the sender, recipient, and value of transactions on the blockchain. Users have complete control and can choose to provide others with their view key to see the contents of transactions. Zcash is open-source and allows users to control their data, providing a decentralized and privacy-protecting digital currency platform.
