Can you stake on Ethereum?

Can you clarify for me if staking is possible on the Ethereum blockchain? I've heard of people earning rewards by locking up their crypto assets to support the network, but I'm not sure if Ethereum offers this feature. If it does, can you provide some insight into how the staking process works on Ethereum and what are the potential benefits or risks associated with it? Additionally, are there any specific requirements or limitations that I should be aware of before considering staking on Ethereum?
