Emercoin (EMC) is a decentralised, open-source cryptocurrency created in late 2013 and based on technologies from Bitcoin, Namecoin and Peercoin. It is a hybrid proof-of-work/proof-of-stake (PoW/PoS) coin which uses the SHA-256 hashing algorithm to "mine" the coins and it also offers a 6% annual interest on staked coins. Emercoin implements the RFC3489 (STUN) protocol that uses geographically distributed servers for external IP discovery. Another interesting feature of Emercoin lies in its blockchain which provides a name-value storage system, including an integrated DNS server for *.coin, *.emc, *.lib, *.bazar domains.
