How Does the Size of the Nonce Field Affect Mining?
The nonce field's size (e.g. 32 bits) determines the maximum number of possible values a miner can iterate through for a given block header before needing to change another variable, such as the timestamp or the Merkle Root.
A larger nonce allows for more unique hashing attempts without altering other block data, which is crucial for the high hash rates seen today.
