Nxt

NXT coin is also called future coin, which is considered as the second generation cryptocoin. It was written in new code: not based on the Bitcoin codebase, but in Java. NXT is also a pure POS coin, forging new blocks in transparent forging, which improves on many of bitcoin's features, such as 1-minute confirmation. In addition, it also avoids many defects of the cryptocoin generation, such as resource consumption and vulnerability to attack.
