Zcash (ZEC) is an open source cryptocurrency based on the Bitcoin protocol that, through its decentralized system, offers full transparency and privacy of transactions to its network of users. Zcash has its own public blockchain but the data related to transactions (such as the sender, recipient and size) are kept confidential. Despite being created based on Bitcoin, ZEC seeks to keep its network totally anonymous through the Knowledge Protocol Zero (ZKP), which is the linchpin for the rigorous privacy aspect of this cryptocurrency.
