Difficulty

Difficulty, in the context of blockchain technology, refers to a dynamically adjusted measure of how challenging it is to find a hash that meets a specific target requirement for a new block. This mechanism is crucial for Proof-of-Work (PoW) blockchains like Bitcoin, ensuring that blocks are produced at a relatively consistent rate, regardless of the total computational power (hash rate) on the network. Without difficulty adjustment, an increase in miners would lead to blocks being found too quickly, destabilizing the network.
