V.SYSTEMS is a blockchain infrastructure provider with a focus on database and cloud services. Powered by the Supernode Proof-of-Stake (SPoS) consensus algorithm, each supernode is elected in a decentralized network according to Proof-of-Stake (PoS) principles, providing high performance minting, transaction processing and smart contract functions. VSYS is the native currency for the V.SYSTEMS blockchain platform with a multitude of uses including transactions, staking and minting on the network. V.SYSTEMS aims to deliver decentralized cloud database technology with high scalability, durability and performance. With Sunny King as the lead architect, V.SYSTEMS has already designed and implemented SPoS Consensus, a super efficient distributed consensus algorithm with the highest resistance to 51% attacks. The network plans to operate as a cloud platform based on modular systems that can support efficient and agile development of a vast variety of applications including but not limited to finance (DeFi), entertainment, social network and many more.
Novacoin is a hybrid Proof of work (POW) / Proof of stake (POS) decentralized peer-to-peer cryptocurrency.The Proof of Work part of Novacoin is based on the Scrypt hashing algorithm. Proof of Stake contributes to the coins energy efficiency, as there is no need for nodes to contribute mining power to part of the money creation process. As of now, Novacoin is set to be capped at 2 billion coins. However Novacoin stated that the cap limit may be lifted if the situation requires it. It looks very much like a variation of Sunny King Peercoin.
