Can a Validator’s Stake Be Delegated by Other Token Holders?

Yes, in many Proof-of-Stake (PoS) systems, token holders can delegate their stake to a validator. This model, often called Delegated Proof-of-Stake (DPoS), allows users who don't have enough funds or technical knowledge to run their own validator node to still participate in securing the network and earning rewards.

They entrust their tokens to a validator, who then stakes on their behalf and shares a portion of the earned rewards. This increases decentralization by allowing more people to participate in the consensus process.
