Auroracoin is a cryptocurrency for Iceland that is launched in February 2014. It is 50% premined and the coins will be distributed free-of-charge to all 330,000 citizens of Iceland via an airdrop starting from the midnight of 25th March 2014. Auroracoin is created as an alternative to the Icelandic krona. The movement of krona is severely restricted by the government and its value has dropped significantly against gold and the dollar since 1960. Each Icelandic national will receive 31.8 auroracoins during the airdrop. The creator of auroracoin goes by the pseudonym Baldur Friggjar Odinsson. Aurorcaoin is a clone of Litecoin.
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.
