Haven is developing a blockchain-based ecosystem of multiple decentralized coins. The Haven protocol places an emphasis on privacy and price-stability, and like Monero, is based on the CryptoNote protocol. Haven has a Proof-of-Work (PoW) consensus mechanism that is AISC-resistant, and has a dynamic block size. The platform is powered by the XHV coin.

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.

DASH, or digital cash, is a leading anonymity-centric digital currency that was created as a fork of the Bitcoin protocol. DASH allows users to make anonymous transactions instantly with very low fees.
DASH uses a lighter hashing algorithm (X11) and has a block time of 2.5 minutes. This significantly increases transaction time compared to bitcoin. It also introduced a system based on "Masternodes" and "Instasends" that provide incentives to users for securing the network and contributes to making transactions faster.
Users invest 1,000 DASH to host a Masternode, and then receive 45% of the reward for every block that is mined. DASH was designed with a decentralized governance model and a sustainable funding system that allocates a percentage of each block for network development purposes.
Although, Dash has not been able to attract as many developers and financial institutions as other cryptocurrencies, it is well positioned to continue growing and innovating.
