Resolve the Current Epoch's Leader Schedule

with Solana

Resolve who leads now and who leads next in the current epoch.

  1. Read the current epoch, the absolute slot, and the position inside the epoch, which anchors every schedule lookup that follows.
  2. Read the schedule that maps slots onto epochs, including the warmup period and the offset at which a leader schedule is published ahead of its epoch.
  3. Fetch the leader schedule for the current epoch, keyed by validator identity with the slot indices each one is assigned.
  4. Identify the validator leading the current slot, the node a client would forward a transaction to right now.
  5. List the leaders for the slots immediately ahead of the current one, which is what lets a client pre-connect to the next producer instead of the current one.
What you'll need to have ready
  • upcomingLeaderCount: How many upcoming slot leaders to list, starting at the current slot.
