HedgeTrade is a decentralized prediction market focused on a wide variety of financial assets. Trade predictions can then be purchased using the HEDG token for users to replicate and learn from. Correct trade predictions award the trade predictor with the HEDG tokens originally put forth by those individuals who purchased that prediction originally through the marketplace. Incorrect trade predictions see the HEDG tokens used to buy that prediction returned to the original buyer(s).
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.
