How does a rocket pool work?

As a keen observer of the cryptocurrency and finance world, I'm intrigued by the concept of rocket pools. Could you elaborate on how a rocket pool functions in a practical sense? Specifically, I'm curious about the mechanism behind it, how users can participate, and what kind of incentives or rewards are offered for contributing to the pool? I'm also wondering if there are any security measures implemented to safeguard participants' funds and ensure the stability of the pool. Understanding the inner workings of a rocket pool could potentially provide valuable insights into how decentralized finance operates and how it could shape the future of finance.
