Dero is developing a Proof-of-Work (PoW) blockchain with a DAG block structure. Their goal is to enable anonymous and fast transactions, with a high degree of encryption. The platform will also have smart contract functionalities.

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.

TurtleCoin is a privacy-focused coin with a short block time. It was created by two developers that call themselves Bebop and Rocksteady. Their goal was to create a cryptocurrency that was focused on community development and did not require a large ICO. Turtlecoin has a short block time of only 30 seconds, and has many of the same privacy features as Monero (XMR). TurtleCoin has a Proof-of-Work (PoW) consensus mechanism.
