8. Payout (Recommended)
Payments for blocks and cMixx rounds occur at the end of every era. There may be tips voluntarily paid by authors of signed extrinsics and deductions (slashes) as well.
After every era, Node that participated may distribute its earnings to the validator and nominators (if any).
While this is an optional task for the validator because anyone can perform payout, it is considered to be one of validator's services. If you look at a validator's details in XX Network Explorer, regularity of payouts is one of validator's quality metrics:
frequency of payouts
Very Good, validator has 0 era unclaimed.
Furthermore, unclaimed rewards (those that haven't been paid out) expire in about 80 days.
It is therefore recommended for validators to perform this task daily and make staking more convenient for the nominators.
If the validator does not perform payout, usually one of the alert nominators may do it for the Node (each payout distributes all unpaid rewards for the validator and other nominators, if any).
Pay rewards using XX Network wallet
As mentioned here, payouts can be performed from the XX Network Wallet.
The main downside is this requires daily access to the XX Network wallet.
Other payout methods
You may automate your payout or "outsource" it to another wallet owner ("payout service provider").
That way your payouts be regular and do not require access to the XX Network Wallet.
Please inquire within the community regarding current options.
