## Proof of Work Computational Cost

Proof of Work Computational Cost refers to the massive amount of energy and hardware investment required to secure a blockchain through the mining process. Unlike proof-of-stake, which uses capital, proof-of-work relies on physical resource expenditure to prove honesty.

This cost is a direct measure of the network's security, as an attacker would need to control more than half of the total computational power to compromise the system. This creates a tangible, real-world barrier that is extremely difficult and expensive to overcome.

While often criticized for its environmental impact, proof-of-work remains the most battle-tested consensus mechanism for security. The cost is a feature, not a bug, as it makes the network censorship-resistant and immutable.

Understanding this cost is essential for analyzing the long-term viability and security of proof-of-work chains, as it ties the network's survival to the price of the native token and the efficiency of mining hardware.
