Imagine a network of miners competing to solve complex puzzles to secure the Ethereum blockchain. Ethereum difficulty is like a knob that controls how hard these puzzles are. The more miners there are, the harder the difficulty gets to keep block creation at a steady pace. This difficulty setting helps maintain the security of the network and prevent malicious activity. However, with Ethereum transitioning to Proof-of-Stake (PoS), the role of difficulty might change in the future.
