Story

What the post asked, what the answer turned out to be, and what the chain says happened. The record below holds the data.

Darling

"How should I call you, darling?"

Alistair Darling, Chancellor on the day of the genesis block. Addressed the way his Wikipedia article says: The Rt Hon Alistair Darling MP. The post misprinted the end of the block 62 key, and a player caught it.

The winner wrote a long report on how they got there. The author's Wattpad chapter spells the whole string out.
