Staking AVAX, by Validating or Delegating, with the Avalanche Wallet. When a validator is done validating the Primary Network, it receives back the AVAX tokens it staked. It may receive a reward for helping to secure the network. A validator only receives a validation reward if it is sufficiently responsive and correct during the time it validates. A delegator is a token holder, who wants to participate in staking, but chooses to trust an existing validating node through delegation.
