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.
