Nasdacoin is developing a blockchain with a hybrid consensus mechanism that combines elements of Proof-of-Work (PoW) and Proof-of-Stake (PoS). Nasdacoin uses the Scrypt hashing algorithm and is powered by the NSD coin. The company plans on developing a comprehensive ecosystem with a native exchange, wallet, App, and marketplace. They also plan on allowing Nasdacoin holders to transfer their NSD balance to a Visa card that can be used anywhere.

Litecoin is a crytptocurrency that was created to serve as the “silver” to bitcoin’s "gold." It is based on the core Bitcoin protocol, but was designed with several key features that provide it with advantages over Bitcoin.
Litecoin has significantly reduced transaction times by limiting the target block processing time to 2.5 minutes. It also has a total coin supply that is 4 times larger, and utilizes a different hashing algorithm called Scrypt, that requires a smaller workload and less computation power than Bitcoin's SHA-256 algorithm. This enables much faster transactions at a much lower cost to users. These features make Litecoin easier to use and to mine. Since its creation, Litecoin has gained a large market cap and widespread adoption among cryptocurrency users in need of a coin for everyday transactions.

PRIZM is an open-source cryptocurrency based on the NEXT core. The PRIZM architecture is built in JAVA. It has a Proof-of-Stake (PoS) consensus mechanism that varies slightly from other PoS algorithms. It is designed to be more resistant to attacks against the network. PRIZM has developed the concept of paramining, which helps the network achieve consensus and encourages community participation.
