What Is The Difficulty Adjustment?

Difficulty Adjustment in Bitcoin refers to the periodic recalibration of how hard it is for miners to create a new block. Every 2,016 blocks, or roughly every two weeks, the difficulty is automatically adjusted to ensure that Bitcoin blocks are mined approximately every 10 minutes. This adjustment keeps the network stable and predictable despite changes in the number of miners or their collective computational power. If mining speeds up due to more miners or better technology, the difficulty increases; if mining slows down, the difficulty decreases. The target for this difficulty is encoded within each block, guiding miners on the required Proof-of-Work.
