 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.

 === Future of Currencies
 
-The future of cryptographic currencies overall is even brighter than the future of bitcoin. Bitcoin introduced a completely new form of decentralized organization and consensus that has spawned hundreds of incredible innovations. These inventions will likely affect broad sectors of the economy, from distributed systems science to finance, economics, currencies, central banking, and corporate governance. Many human activities that previously required centralized institutions or organizations to function as authoritative or trusted points of control can now be decentralized. The invention of the blockchain and consensus system will significantly reduce the cost of organization and coordination on large-scale systems, while removing opportunities for concentration of power, corruption, and regulatory capture.
