V Systems is a blockchain platform that was developed by Sunny King, the creator of Peercoin and Primecoin. Peercoin was one of the first Proof of Stake Coins, and V Systems is designed to improve upon the consensus mechanism with a better staking system.

Nxt is a blockchain platform developed by Jelurida, which is also developing the Ardor blockchain. Nxt's goal is to improve upon existing blockchain platforms with a modular toolset that enables users to create their own digital assets that can be listed on decentralized marketplaces. Nxt also features community driven voting mechanisms and has an architecture that separates the blockchain into parent and child blockchains.
The network is powered by the NXT token and has a Proof-of-Stake (PoS) consensus mechanism.
