How does Marinade Finance work?

Could you elaborate on the functioning of Marinade Finance in a concise manner? Specifically, I'm interested in how it leverages blockchain technology and smart contracts to provide its unique services. How does the staking mechanism work within Marinade? And furthermore, how does it ensure the security and liquidity of the staked assets? I'm also curious to know if Marinade offers any incentives or rewards for users participating in its staking program. I would appreciate a high-level overview of its operation and the key factors that differentiate it from other similar platforms in the cryptocurrency space.
