 NXT (pronounced "Next") is a "pure" proof-of-stake alt coin, in that it does not use proof-of-work mining. NXT is a from-scratch implementation of a cryptocurrency, not a fork of bitcoin or any other alt coins. NXT implements many advanced features, including a name registry (similar to((("Namecoin"))) Namecoin), a decentralized asset exchange (similar to Colored Coins), integrated decentralized and secure messaging (similar to((("Bitmessage"))) Bitmessage), and stake delegation (to delegate proof-of-stake to others). NXT adherents call it a "next-generation" or 2.0 cryptocurrency.
