Also, there is some traffic related to this address on testnet3.

I myself could reproduce the private key from scratch, using only the information that is publicly available on the blockchain.

I have made it so that the puzzle can be solved with any computer that could run Bitcoin Core.

I could be wrong, but if the whole challenge can be completed with Bitcoin Core, [...]

Clarification: I didn’t say that it could be solved with Bitcoin Core. In the context of discussing hardware requirements, I said that it can be solved with any computer that could run Bitcoin Core. It my way of saying that you don’t need fancy, expensive hardware for this. I love how Core has kept it possible to Be Your Own Bank on inexpensive devices. Poor people are welcome to try this. You can solve it just as well on a Raspberry Pi as on a many-core Xeon. Bitcoin is for everyone!

People with GPU-farms can grind on it however they want, as much as they want. It will not help. Finesse, not force will solve this. The key is cryptographically as “strong” as any Bitcoin key—but I leaked information about how to reconstruct it. Security through obscurity: Can you find the clues hidden in plain sight? Even if you can find them, can you guess my thought process for putting it all together?

Reconstructing the key will require at least intermediate-level Bitcoin knowledge—not real wizardry, but definitely not newbie-level. If I created a txid that starts with 36 zero-bits, I obviously wrote some custom code for this. (Call that “Proof of Something-More-Than-Meets-The-Eye”.) Retrieving the money would be easier, but at least a modicum of skill and effort will be needed.

[...ideas for how to solve it...]

I will not give an further hints. 😼

So it is not yet taken, because it is based on "security through obscurity".

That part, in itself, is entirely correct.

Another question is if that challenge will be upgraded to Taproot? Because if it is really based on HMAC-SHA256 or things like that, then it could be as well based on Taproot, where there are endless possibilities for a brainwallet TapScript, exactly in the same way, as there are endless possibilities, when it comes to signing some transaction. As I said, it is based on obscurity, and that's the only reason why nobody moved it yet.

I have no intention to “upgrade” this puzzle, but I am excited by some of the possibilities offered by Taproot for other purposes.

Earlier in this thread, I quoted a post in which Lauda presented a female image and spoke of her “husband”, in a context where I think that she was probably joking; see also my take on it. Other forum members have dug up posts where Lauda seemed to indicate or imply being a man. I think it’s likely that the apparent contradictions were not unintentional.

Lauda is "he" and anyone thinking otherwise is just fooling themselves. [...old posts indicating that Lauda was a man...]

nullius is lauda. That is very clear. Anyone who does not see this is simply closing their eyes.

With apologies to Quickseller, who is a gentleman. Sorry, it is just too funny here.

LOL, at least I admit that I don’t know. You are so sure. I am sure that you know less than I do—and I don’t know.

Flip a coin, pick a pronoun, and stick to it.
