Re: Bitcoin challenge transaction: ~100 BTC total bounty to solvers!
For my certainty: what range applies to address 105 (this is the first of the unused, which has the output and pubkey transactions). Something I have to check, high compartment, and it's time to waste a pity :-) According to my calculations, the beginning is 0000000000000000000000000000000000000100000000000000000000000000?
Correct me if I'm wrong but start: 100000000000000000000000000 2^104end: 1ffffffffffffffffffffffffff 2^105 -1
Plz share if you get any luck
Re: Bitcoin challange transaction: ~100 BTC total bounty to solvers!
By the way, isn't it kinda scary that a few keys in 80 and 90 bit ranges were already found? Many users have passwords with less bits of security, and passwords also aren't random, so bruteforce can be optimized. Or am I missing something, and those keys were cracked with some algorithm rather than brute force?
So, I did it and it takes 2.5 ms for me to calculate an address from a raw private key
They were bruteforced it just so happened that they were found, it's luck, just someone started close enought. There are different algos for password cracking words-list attacks for example. There's a way this puzzle is usefull, for one it proves there's no time travelers, for two it shows how secure bitcoin and other 256 bit keys are. I would choose not to generate addresses at all just sweep all the range that you go by, it would save time.if you want to have fun, you can program something. i did that a while ago in c# for small ones as a "challenge" to my skills knowing there is no other reward.

Re: Bitcoin "puzzle" transaction: ~100 BTC is still available!
It's funny and irony, a programmer offers their services or software to crack bitcoins with some money. So why don't they crack Bitcoin themselves, I'm sure those crack software makers will get more profits.
They might not have enough hardware (or money for said hardware, don't you need in the order of terabytes of memory at this point?) to grab the remaining keys so they're better off selling the software.
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!
Just a reminder for those who joined us here lately ...
This guy, saatoshi_rising, is certainly the creator since he moved the range 161-256 as promised on July 11th 2017
I've got a question.
Are we sure that the numbers are 100% random? I mean can there be a way of predicting exactly what the next key is or just it's range of values?

Yes. The numbers are 100% random.
This knowledge comes directly from the creator.
This is known ... Each subsequent address is in the range of one higher than the previous one, i.e. if address # 58 was in 2 ^ 57 then # 59 is in 2 ^ 58. This is the only rule that takes place here and also comes from the creator.
