Bitcoin Private is a community-driven fork of the Bitcoin protocol. It is somewhat unique in that it was created as a result of a privacy-focused co-fork of Bitcoin and ZClassic. Coins were distributed on a 1:1 basis to BTC and ZCL holders. Bitcoin Private (BTCP) uses the same privacy technology as ZClassic (zk-snarks). Transactions are published on a public blockchain, but the sender, recipient and other transactional metadata remain anonymous. Bitcoin Private has a larger block size, and enables anonymous transactions that are more secure than the original Bitcoin protocol.

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.
The founders of Hush are closely associated with Komodo.

TokenPay is a Proof-of-Stake (PoS) blockchain powered by the native TPAY coin. TokenPay hopes to encourage wider adoption of its cryptocurrency by focusing on privacy and merchant services that will make it easier for crypto to be widely used as a medium of exchange. TokenPay also places a strong emphasis on security and anonymity. The network's architecture uses zero-knowledge proofs, ring signatures, and other features to increase privacy. They are also developing an encrypted messaging system that allows users to communicate securely within their network secure communication interface
