Who this is

A Steemit account, and the winner Zden's own catalogue links to. That link is the whole attribution: Zden's page calls the article "Solution article by the winner", and it points here.

Level 4 went up on June 7, 2017 with a bit more than 0.026 BTC, as one of Zden's pictures that look like modern art until you notice the dots. Two grids, dots and circles on top of them, and curves running through. Each of seventeen quadratic Bézier curves gives three characters, which makes 51, which is exactly the length of an uncompressed WIF. The circle sizes tell you the order. The prize moved on June 11.

What the record says and what it doesn't

One fact, the article. It opens with a WIF as an example of the format, and that example is not the answer, so it's nowhere in the record. The key itself was never published, which is why the puzzle has a public key and no private one. An example WIF in a solution article is a trap for anyone who skims.
