What Is Bitcoin Mining Difficulty? Put simply, mining difficulty refers to the complexity of the computing operations that a device has to perform in order to mine new bitcoin (or another type of cryptocurrency, if you're using a different blockchain). Why would mining difficulty vary over time? The reason is that changes in mining difficulty ensure that the blockchain grows at a relatively constant rate, even if the number of miners on the network or the computing power that they control fluctuates.
