Loki is developing a privacy-focused blockchain that will enable private transactions and decentralized communication. The Loki blockchain will be complemented by Lokinet and SNApps. Lokinet will use onion routing to allow users to access the internet privately without revealing their IP address. SNApps are web applications that will be located inside the Lokinet, and will be resistant to censorship. The Loki network is powered by the LOKI coin. It has a Proof-of-Work (PoW) consensus mechanism. Service nodes, on the network, are paid to process transactions and route the network's traffic and messages.

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.
