What is cryptocurrency staking?
Could you please elaborate on the concept of cryptocurrency staking in a concise yet comprehensive manner? I'm interested in understanding the fundamentals of this process and how it differs from traditional mining. Specifically, I'd like to know about the role of validators, the requirements for staking, potential rewards, and any associated risks. Additionally, is staking available for all cryptocurrencies, or are there specific ones that support this feature? Thank you for your assistance in clarifying this topic.
