Stake delegation refers to the process where a cryptocurrency holder assigns their staking rights to another party or validator in a proof-of-stake system. This allows the holder to earn rewards without having to run their own validating node.In this setup, the delegated stake contributes to the overall voting power of the validator. The validator then processes transactions and secures the network on behalf of the delegates. As a result, those who delegate their stake receive a share of the rewards generated by the validator based on the amount they contributed.This arrangement benefits both parties. Validators gain more capital to commit to maintaining the network, while delegators can participate in staking and earn rewards without the technical challenges and operational costs of managing their own nodes. Stake delegation often involves trust, as the delegator relies on the validator to act honestly and effectively.Many blockchain platforms implement stake delegation with built-in protocols to manage rewards distribution, ensuring transparency and fairness in the process.
