On Solana mainnet-beta, in which epoch number does slot 317300249 fall? Answer with the whole number only.
Answer
734
- slot
- Absolute mainnet-beta slot number since genesis.
- epoch_numbering
- Use mainnet-beta getEpochSchedule: firstNormalSlot 0 and slotsPerEpoch 432000; epochs are zero-indexed intervals [epoch*432000, (epoch+1)*432000).
