How this winner was picked

Every input below is published so anyone can recompute the result. The order matters: each step was fixed before the next one could be known.

Anyone can replay this draw with the verifier script in the repository, scripts/verify-receipt.mjs.

  1. 01

    Snapshot frozen

    Every holder balance was read at one finalized slot, 446,411,901. Nothing bought after this slot could change the draw. Slot 446,411,898 was the finalized head when the pot tripped the target; the cluster answered at the slot above, so both are recorded.
