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.

Spectrecoin is a privacy-focused cryptocurrency with a Proof-of-Stake (PoS) consensus mechanism. Spectrecoin uses ring signatures, stealth addresses, and Tor to provide privacy and anonymity.

Bytecoin is a privacy focused blockchain that aims to be completely anonymous. It is the first digital currency based on CryptoNote technology and uses ring signatures. Bytecoin utilizes one-time addresses and multi-signatures to enhance security. Bytecoin has high transaction speeds and users are in complete control their personal information. Any identifiable details can only be seen if you allow it. Bytecoin, and CryptoNote, have led to several popular forks. Monero and Dash are both Bytecoin forks. The CryptoNote Proof-of-Work (PoW) algorithm was designed to provide ASIC resistance and enables anyone with a personal computer to mine it.
