Pirate Chain is a privacy focused cryptocurrency that is based on Komodo's dPoW consensus mechanism. Pirate Chain uses ZK-Snark cryptography to secure transactions that are sent on their anonymous, decentralized network.

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.

Haven is developing a blockchain-based ecosystem of multiple decentralized coins. The Haven protocol places an emphasis on privacy and price-stability, and like Monero, is based on the CryptoNote protocol. Haven has a Proof-of-Work (PoW) consensus mechanism that is AISC-resistant, and has a dynamic block size. The platform is powered by the XHV coin.
