Diamond (DMD) is a Proof-of-Stake coin focused on scarcity. Their marketing materials emphasize the limited circulation of the coin, and the benefits of the network's incentivized cloud mining system, which rewards users for contributing their computing resources.

ZCoin is a privacy focused cryptocurrency built on Ethereum. The ZCoin protocol enables anonymous transactions with cryptography that utilizes Zero-Knowledge Proofs (ZKP). ZCoin increases privacy on their network by using a coin-mixer contract that wraps transactions in a serial number and destroying wrapped coins once they have been redeemed.
Zcoin was the first cryptocurrency to use a Merkle Tree Proof (MTP) as its proof of work algorithm. Merkle Tree Proofs are an innovative solution to achieving network consensus, and can increase transaction time while reducing the centralizing tendency of ASIC mining.

MOL is developing a blockchain platform for micro-payments. MOL's architecture will be based on the block lattice design used in Nano, and will have a Delegated Proof-of-Stake (dPoS) consensus mechanism that incorporates elements from Directed Acyclic Graphs (DAG). The MOL network is currently powered by the Ethereum-based MOL token.
