The situation became so dire that by 2014, Dogecoin had to hard fork – make a permanent change to its blockchain – to allow “merged mining” or auxiliary proof-of-work (AuxPoW) with Litecoin. It was essentially a method for miners to provide security to both blockchains simultaneously. “There's absolutely an easy way to save the coin from its certain death (and by death, I mean 51% attacked for the lulz),” Mohland continued. “And that's AuxPoW." Merged mining is when miners simultaneously secure two or more networks, receiving rewards from both without a deterioration in performance. The reason it’s called auxiliary proof-of-work is because the process involves a less secure auxiliary blockchain borrowing security from a parent network with stronger security. In this scenario, Lee suggested that Litecoin could provide much-needed security to the embattled Dogecoin network.
