'UNI COIN describes itself as a cryptocurrency that is issued for the purpose of protecting investors. This is done in cooperation among different crypto issuers, by joint market-making and supporting the value of each token. Issuers adopting UNI COIN can save costs and diversify risks by combining everything together; exchanges, wallets, the payment system, and IR.'
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.
