How Does Hashrate Serve as an Indicator of Network Security?

Hashrate is a primary indicator of the security and robustness of a Proof-of-Work network. A higher hashrate signifies that more computational power is being dedicated to mining, making the network more resilient to attacks.

Specifically, a high hashrate makes a 51% attack prohibitively expensive and difficult to execute, as an attacker would need to amass more computational power than all other honest miners combined. Therefore, a consistently high and growing hashrate is often seen as a sign of a healthy, secure, and well-supported blockchain, inspiring confidence among users and investors.
