Emerald Crypto (EMD) is a cryptocurrency based on LiteCoin. It uses proof of work (POW) to create distributed trustless consensus and solve the double-spend problem. There are dedicated seed nodes for syncing into the right blockchain. Emerald Crypto uses 20 second block time for continuous confirmation of the transactions on its blockchain. The mining difficulty is retargeted after each block and is calculated by using the Dark Gravity Wave 3 algorithm. It is an open source project, that rebranded from Emerald to Emerald Crypto on August 04, 2014.
