Story

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

Impossible on purpose

The author hates the number 13, so this block asks for something that didn't exist yet: the first seven words of the hint to block 77. No hints until then, the post promises. The post even printed this key's own tail, xhm, so block 14 could go on without it.

The hint turned out to be the final version of the Wattpad chapter Second, published in July. Its first seven words, headings included, are Second Second Life Second Coming I thought. Add xXJ, hash, done.

The claim came on July 23, 2019, 105 days after funding. A player posted the whole string 49 minutes later. The author never confirmed it, but the chain did.
