Review on Zcash by Francisco Varela
Zcash
Zcash is an implementation of the "Zerocash" protocol. Based on the Bitcoin code, Zcash aims to offer a much higher standard of privacy through a sophisticated zero-knowledge proof scheme that preserves the confidentiality of transaction metadata.

Pros
- Zero knowledge tests allow you to verify transactions without revealing the sender, recipient, or transaction amount. The selective disclosure features included in Zcash allow a user to share certain details of the transaction, in order to comply with current regulations or for audits.
- Zcash allows transparent transactions, compatible with wallets and exchanges that do not support private transactions.
- Zcash supports fast transactions with a low fee of .0001 Zcash. Zcash supports a large number of wallets and top exchanges.
- Zcash is based on sound science and is meticulously audited by third parties. It is an open source protocol, created by a specialized security engineering team, and originally based on Bitcoin Core's battle-proven code base.
Cons
- The blockchain and network keep track of how many coins are protected, and they don't care who withdraws a portion later. The coins go to a large group and when you take out a small piece, there is no way to correlate it with what initially entered the group.
