The protocol does not have a separate definition of time. Changes to staking get reflected every day at 00:00 UTC.
There is a 2 day delay for staking rewards to be calculated and distributed to stakers.
Reward payouts occur at the first block after 00:00 UTC.
Slashing and penalty apply to the validator’s own stake.
Staking happens on BNB Beacon Chain. BNB Smart Chain is where execution happens. BNB Beacon Chain is where consensus and governance occurs.
Reward payouts occur at breathe blocks. The first block after 00:00 UTC is called a breathe block. This is when any staking changes are applied and rewards are distributed.
Rewards come from transaction fees. BNB Smart Chain burns 10% of the transaction fees incurred on its chain (see BEP-95 for more on fee burns). The rest is distributed to validators and stakers as rewards.
Factors that impact realized rewards.
Validator performance. If a validator misses more than 50 blocks in a given day, that validator will not receive any rewards for that day.
Commissions.
Slashing and penalty apply to the validator’s own stake. Delegators’ stake is not at risk.
