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.

DigitalNote is developing a privacy focused blockchain whose transactions will be resistant to analysis. The network will have a hybrid Proof-of-Work (PoW) and Proof-of-Stake (PoS) consensus mechanism and will be powered by the native XDN coin.
