The validator APY calculation is conceptually the same as the Delegator APY% in terms of calculating and using stake-weighted rewards. Noise is also filtered out by only taking into account validators who have been active for the whole time window.A validator’s total rewards take into account their commissions from voting rewards, block production fees (base fees and priority fees), and commissions from MEV extracted through Jito if applicable.
APY%=time period in secondsvalidator’s rewards per stake in SOL×365d×24h×60m×60s
On the 1d time period, the APY takes into account the rewards received for the last 3 days to smooth out the noise given Solana’s staking rewards schedule, which is every epoch (~2 days).
