 ### What is 'staking'?
 
-The Cosmos Hub is a public Proof-Of-Stake (PoS) blockchain, meaning that the weight of validators is determined by the amount of staking tokens (Atoms) bonded as collateral. These Atoms can be seld-delegated directly by the validator or delegated to them by other Atom holders.

 Any user in the system can declare their intention to become a validator by sending a `create-validator` transaction. From there, they become validator candidates.

 Each member of a validator's staking pool earns different types of revenue:
 
 * **Block rewards:** Native tokens of applications run by validators (e.g. Atoms on the Cosmos Hub) are inflated to produce block provisions. These provisions exist to incentivize Atom holders to bond their stake, as non-bonded Atom will be diluted over time.
-* **Transaction fees:** The Cosmos Hub maintains a whitelist of token that are accepted as fee payment. The initial fee token is tha `atom`.

 This total revenue is divided among validators' staking pools according to each validator's weight. Then, within each validator's staking pool the revenue is divided among delegators in proportion to each delegator's stake. A commission on delegators' revenue is applied by the validator before it is distributed.

 ### Do validators need to self-delegate Atoms?
 
-Yes, they do need to seld-delegate at least `1 atom`. Even though there is no obligation for validators to self-delegate more than `1 atom`, delegators should want their validator to have more self-delegated Atoms in their staking pool. In other words, validators should have skin in the game.

 In order for delegators to have some guarantee about how much skin-in-the-game their validator has, the latter can signal a minimum amount of self-delegated Atoms. If a validator's self-delegation goes below the limit that it predefined, this validator and all of its delegators will unbond.
