How Does Hashrate Serve as an Indicator of Network Security?

Hashrate measures the total computational power used to process transactions and secure a Proof-of-Work blockchain. A higher hashrate means more miners are competing to validate blocks, making the network more robust.

This increased power makes it prohibitively expensive and difficult for a malicious actor to gain control of a majority of the network's power (a 51% attack). Therefore, a rising hashrate signals strong miner participation and greater resilience against attacks.

A low hashrate implies fewer miners, increasing vulnerability.
