Merged mining

Merged mining is the practice of using work done on one blockchain on more than one chain. Typically, this is achieved through an Auxiliary Proof-of-Work mechanism that allows miners to use hashrate from another network. Merged mining allows for multiple coins to be mined without adding extra hashrate or diminishing the rewards of the primary coin being mined. Common examples of merged mining include Bitcoin and Hathor, as well as Litecoin and Dogecoin.
