Hush is a cryptocurrency and messaging protocol that is focused on privacy. It uses a the equihash mining algorithm, which is a Proof-of-Work (PoW) consensus mechanism. It offers a high degree of privacy, and allows users to transact and send messages anonymously.
Hush is a fork of Zcash, and uses zk-SNARKS for zero-knowledge cryptography. Hush will allow developers to deploy Ethereum smart contracts on the Hush network.

Bytecoin is a privacy focused blockchain that aims to be completely anonymous. It is the first digital currency based on CryptoNote technology and uses ring signatures. Bytecoin utilizes one-time addresses and multi-signatures to enhance security. Bytecoin has high transaction speeds and users are in complete control their personal information. Any identifiable details can only be seen if you allow it. Bytecoin, and CryptoNote, have led to several popular forks. Monero and Dash are both Bytecoin forks. The CryptoNote Proof-of-Work (PoW) algorithm was designed to provide ASIC resistance and enables anyone with a personal computer to mine it.
