*NXT* ===== NXT
((("NXT alt-coin")))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 crypto-currency, not a fork of bitcoin or any other alt-coins. NXT implements many advanced features, such as 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 (delegate Proof-Of-Stake to others). NXT adherents call it a "next-generation" or 2.0 crypto-currency. ((("NXT alt-coin")))NXT (pronounced "Next") is a "pure" proof-of-stake alt-coin, in that it does not use proof-of-work mining.
