Guys, stop trying to pressure the solver into doing anything. If you're nice, maybe he will stay and you can learn something from him.
We are all grateful for WP's post, sharing a method to securely withdraw a puzzle prize. Nobody is obligated to tip anyone just because you used MARA. You can always show your appreciation for what you've learned by directly sending a tip yourself.

It is not about a donation; that is up to each person if they feel like donating or not. It is more about valuing the contributions and not undermining them. He talks as if it were a 100% original milestone. It is obvious that his solution is just a method already exposed here, and its only advantage was great computing power. So, unless it is something else, the answer is simple: he has nothing to teach us that we do not already know. From what he says, random method with thousands of GPUs are things we already know. I suppose the most he could have added to the software is a database that records already scanned sectors to skip them later.

Did you read his methodology? It wasn't only random scanning and lots of GPU's.

The method was:

Break up puzzle 67's keyspace into 256 sub-ranges each with 2^58 keys
In each sub range, save every private key that generates an address starting with 48 zero's
Statistically there are 1024 proofs in each subrange
If an average of 1024 proofs are found in a sub-range, it statistically guarantees the whole sub-range has been scanned

What software are you talking about? He used custom software. I'm sure he'd like to keep his competitive advantage to himself.

It was found after scanning 57% of the keyspace in 67 days. Which works out to over 7 trillion keys per second. Which, my napkin math says is around 1600 x RTX4090's.

Several thousand

Pretty close. Would need more than 1600 GPU's if they were not all RTX-4090s.

And right now, ~4 days and 2 hours since puzzle 67 was solved, assuming the same scanning speed, he's already scanned almost 2% of puzzle 68.

We just won BTC67 challenge and earned 6.7 BTC!

We had to check roughly 42 058 576 Trillion private keys before finding it (57% of the possibilities)
It took us (ironically) 67 days

Cheers to @ProofOfDuck for the statistical modeling!
Cheers to everyone who saw an opportunity and helped me fund this thing.

BTC68 Here we come!
