BitNew Chain (BTN), based on the system of peer-to-peer payments and smart contract, through forging a two-tier decentralized blockchain network with standard physical masternode, resource segregation, decentralized computing subsystem BTN-DC, and decentralized storage subsystem BTN-FS etc., aims to extend blockchain applications to the field of hardware.
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.
