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.

Verge is a privacy focused cryptocurrency. It was formerly known as DogeCoinDark and was rebranded to Verge Currency in 2016. Verge uses multiple anonymity-centric networks such as TOR and I2P. The IP addresses of the users are fully obfuscated and transactions are completely untraceable.
Verge is based on the Wraith Protocol that enables users to be able to send and receive payments privately across their blockchain with stealth addressing services and complete anonymity. The protocol provides an additional layer of IP obfuscation as well as the option to utilize stealth addressing services for transactions.
