How Does One Become a Validator in a PoS Network like Ethereum?

To become a validator on a Proof-of-Stake (PoS) network like Ethereum, a user must stake a specific amount of the native cryptocurrency. For Ethereum, this is currently 32 ETH.

The user needs to run a validator client software that connects to the network, proposes, and attests to new blocks. This requires maintaining a dedicated computer with a stable internet connection.

For those who don't have enough funds or technical expertise, they can join a staking pool, where multiple users pool their funds and share the rewards.
