Mining Difficulty
In the case of cryptocurrencies like Bitcoin, mining difficulty is a measurement of how challenging it is to locate a valid hash for a brand-new block in the blockchain. It is a critical part of the mining process and is essential for preserving the network’s stability and security.
Every 2016 blocks in the case of Bitcoin, or roughly every two weeks, the mining difficulty is modified. The network’s overall processing capacity (hash rate) provides the basis for the adjustment.
The mining difficulty will increase to ensure that new blocks are added to the blockchain at a roughly constant rate if the hash rate rises, suggesting more miners are joining the network.
The goal of altering the mining difficulty is to maintain a constant block production time.
