Advanced topics

General

  • 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

  • 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.

Risks

  • Slashing and penalty apply to the validator’s own stake. Delegators’ stake is not at risk.
