The blockchain grants absolute transparency, integrity and immutability of the data stored in the system. Hive coins are used to make demands on factoring companies, who can then compensate them. This process uses the blockchain, which offers a high level of security for all transactions. All seller and borrower data is cryptographically secured in this system.
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.
