What is Marinade staked sol?

Could you elaborate on the concept of Marinade staked sol? I'm curious to understand how it functions within the crypto finance landscape. I've heard it's a staking solution for Solana tokens, but what does that really mean? How does staking with Marinade differ from other staking options? Are there any specific benefits or risks associated with this approach? I'm particularly interested in how it can potentially enhance yield for investors while maintaining the security of their funds.
