Delegating is called nominating on Polkadot.
Nominator caps. Only the top 1,024 nominators of each validator can receive rewards for an era.
Nomination pools. Nomination pools let stakers pool their stake into one pool entity that can then nominate validators.
There can only be a maximum of 128 nomination pools.
Changing validators. Stakers who have directly nominated a validator can switch their selected validator instantly. Stakers who have joined a nomination pool will need to wait 14 days to leave and select a new nomination pool.
Rewards come from newly issued tokens.
Fixed number of tokens issued. 30 million new tokens are issued each year. 10% goes to the ecosystem fund while the rest is distributed to stakers.
Factors that impact realized rewards.
Validator uptime. If a validator’s uptime is lower than 90%, the validator and its delegators will receive less rewards.
Commissions.
Penalties. If a validator is offline for at least 45 minutes in a single day, the validator will be kicked out of the active set and will only be able to join after 10 days.
