DAPS, which stands for Decentralized, Anonymous, Payment, System, is developing a privacy focused cryptocurrency. It is currently an Ethereum-based token, but they are planning on releasing their own blockchain to host the project. DAPS uses the Harpocrates protocol to allow users to send and receive DAPS tokens anonymously. DAPS was previously associated with PeepCoin project, but a disagreement between the developers of the project, ended plans for an airswap of the two privacy focused cryptocurrency projects.

PIVX is a cryptocurrency that is focused on privacy, speed, and low transaction fees. It was originally called Darknet and was forked from DASH. PIVX has a strong focus on community governance.
PIVX (Private Instant Verified Transaction) uses a privacy-centric Proof-of-Stake consensus protocol that allows anonymous staking.

Stealth is a cryptocurrency focused on privacy and and speed. The Stealth blockchain has a Quantum Proof-of-Stake (qPoS) consensus mechanism that is designed to enable almost instant transactions with improved privacy. Validators on the network are assigned a short quantum of time to validate transactions. The protocol combines two types of blockchain ledgers, for different types of transactions, to improve validation speeds on their platform. The network is powered by the XST coin.
