Description
Emercoin began as a hybrid of NameCoin and PPCoin. The software was released on December 11, 2013 without any premine.
Emercoin is more focused on the production of coins by PoS than PoW. The mining has a bonus on the interval 1-512 difficulty for high initial issue of coins.
Further difficulty will gradually increase, increasing the focus on PoS mining.

The Emercoin Name-Value Storage (NVS) feature for storing name->value pairs in the blockchain, is a key component in many of the Emercoin services.
