How does lido staked ETH work?

Could you please explain to me how Lido Staked ETH operates? I'm trying to understand the mechanics behind it. Does it involve staking Ethereum to earn rewards? And how does the staking process work? Also, are there any risks associated with staking my ETH on Lido? I'd like to know more about the security measures taken by the platform to protect users' funds. Additionally, could you compare it to other staking platforms? I'm curious to know how Lido stands out in the market. Thank you for your help in clarifying these points.
