Validators can self-bond, meaning they can delegate BNB to themselves, and they can also receive delegations from any other BNB holders. These bonded BNB acts as collateral and cause each delegate, including validators, to have “skin in the game” so to speak. If any equivocation or byzantine behavior by a validator were to be committed, the validator and its delegates would be slashed a predefined amount of bonded stake.

The minimum self-delegated amount is 10000BNB.
