What Is the Role of Mining Pools in the Context of 51% Attacks?

Mining pools are groups of miners who combine their computational resources to increase their chances of finding a block. While mining pools can help to decentralize mining power, they can also create a single point of failure.

If a single mining pool controls more than 50% of the network's hash rate, it could theoretically launch a 51% attack. To mitigate this risk, many mining pools have policies in place to prevent them from growing too large.
