What is the rocket pool?

Could you please elaborate on the concept of 'rocket pool'? I'm curious to know what it entails and how it functions within the realm of cryptocurrency and finance. Is it a specific type of investment pool? Does it involve staking or mining? What are the potential benefits and risks associated with participating in a rocket pool? I'm interested in understanding its role in the broader ecosystem of digital assets and how it might contribute to the growth and development of the cryptocurrency industry.
