## Who this is

The Reddit account that ate Kierkegaard_Soren's [trivia brainwallet](https://puzzles.agntn.dev/collections/trivia-brainwallet) in one evening. The claim landed at 02:05:31 UTC on November 5, 2017. Eleven seconds after that timestamp: "Claimed it :)". Short and sweet.

Half the prize went to charity. And not just any charity. Quantris named `1HB5XMLmzFVj8ALj6mfBsbifRoD4miY36v`, WikiLeaks' donation address, and the spend pays exactly half the net amount there. Clue 9 was a poem about WikiLeaks. Poetic justice, literally.

Now the best part. The author asked how they got number 12. Quantris just admitted it: they "totally cheesed" it, trying even numbers on brainwallet.io until the address matched. Eleven right answers and a brute force salt. Is that cheating? It's a brainwallet, the address is the referee. And then they posted all twelve answers anyway, with the steps. That walkthrough is where every `answer` on the record comes from. Legend.

## What the record says and what it doesn't

Three facts, one per comment. The claim. The guess on clue 12 with the WikiLeaks address. The walkthrough.

No addresses for Quantris. The other half of the spend went to `1Gfncuhg6hCQBxyrYsTDSwiCRzH7Bhjvru`, but nobody in the thread says whose it is. Probably theirs? Probably. Probably isn't a source, so it stays in the transaction and out of the solver.
