Network Hash Rate

The aggregate computational power (measured in hashes per second) expended by all miners participating in a proof-of-work blockchain at a given time. A higher network hash rate increases attack cost for a 51% attack and triggers upward difficulty adjustments to maintain target block times; conversely, drops in hash rate trigger downward adjustments.
