Block vs Difficulty Adjustment

A block is a container of data in a blockchain that stores a batch of validated transactions, along with metadata like a timestamp and a reference to the previous block, forming an unbreakable chain of transaction history.

Difficulty adjustment is Bitcoin's automatic mechanism that recalibrates mining difficulty every 2,016 blocks to maintain the 10-minute average block time, ensuring consistent block production regardless of whether mining power increases or decreases dramatically.
