Is this puzzle really worth trying to solve? It's been close to a decade. Can someone give me a TL;DR?
There are several puzzles with different bits of diffculty it is exponential, puzzle 66 is 6.6
BTC BTC puzzle 67 is 6.7
BTC.
Puzzles prizes have been incremented in a x10 Factor two times since its creation.

BTCI have another idea,
The puzzle creator said the only thing all the private keys have in common, is that all of them were created from a HD wallet, and then masked from the left with zeros.
Is it any weakness on the HD method of creating wallets? I mean, with the number of private keys already revealed, we could just try to target the searches for the the master private key that was used in the HD wallet.
What do you think?
Regards.
I think that author or this puzzle may used a custom method to generate those keys
This puzzle is very strange. If it's for measuring the world's brute forcing capacity, 161-256 are just a waste (RIPEMD160 entropy is filled by 160, and by all of P2PKH Bitcoin). The puzzle creator could improve the puzzle's utility without bringing in any extra funds from outside - just spend 161-256 across to the unsolved portion 51-160, and roughly treble the puzzle's content density.
If on the other hand there's a pattern to find... well... that's awfully open-ended... can we have a hint or two?
I am the creator.
You are quite right, 161-256 are silly. I honestly just did not think of this. What is especially embarrassing, is this did not occur to me once, in two years. By way of excuse, I was not really thinking much about the puzzle at all.
I will make up for two years of stupidity. I will spend from 161-256 to the unsolved parts, as you suggest. In addition, I intend to add further funds. My aim is to boost the density by a factor of 10, from 0.001*length(key) to 0.01*length(key). Probably in the next few weeks. At any rate, when I next have an extended period of quiet and calm, to construct the new transaction carefully.
A few words about the puzzle. There is no pattern. It is just consecutive keys from a deterministic wallet (masked with leading 000...0001 to set difficulty). It is simply a crude measuring instrument, of the cracking strength of the community.
Finally, I wish to express appreciation of the efforts of all developers of new cracking tools and technology. The "large bitcoin collider" is especially innovative and interesting!
He never mention HD wallet it only mentioned some deterministic wallet
