I spent about $30k over a couple of years renting cloud services to attack these puzzles with no luck. I'm down to about $1k a year in electrical costs running my own equipment right now. It would be interesting to know how much others are willing to gamble on this. Given a large enough pool of money, we should set up a LLC to attempt this in a more organized and professonal manner. If 120 and 125 was cracked by the same person/group then I'm going to suggest that it was done by an investment fund.
Ok, firstly, what do you know about brute forcing, and public key search, reducing bit range etc? I'm sure if you knew enough you'd have solved at least 1 of the puzzles, I don't understand why would you spend money on something based on your luck, this is not gambling, you should only spend money when you are 99.999% certain about your calculations and the success.  If you had asked other people here to guide you well enough or even partnered  with an expert, you'd be counting your coins by now.

It is not advisable to engage financially on solving these puzzles without the necessary knowledge.😐

If 120 and 125 was cracked by the same person/group then I'm going to suggest that it was done by an investment fund.

Not only that, the person that cracked 120 and 125, are also attacking 130 now. So we need to unite.

funny thing  about that group or the person that solved it is that they moved the funds and never touched it. They didn't need to buy more computers or rent more GPUs. I must think they probably must be using some forms of manual calculations to beat the puzzles. Because if they needed more computational force, they probably might be needing to spend from the money to get that achieved. Or probably they had saved so much money from the beginning before starting. It's just a guess anyway. More force doesn't mean higher chances. I have wasted over $15k renting GPUs trying to beat level 66 but I'm out of funds now. The only issue here is the levels with the public keys seem to be more prone to calculations without the need for too many computers if you know what you're doing though. But the levels without the public keys, I'm sure you need a pool of resources to beat those levels. I'm about ready to give up right now but where do I start from if I give up now?

here the opinion has already been expressed that the person who solved the last keys of the puzzle has a large number of farms for mining. He does not need to purchase equipment, since after the completion of the mining of the ether, there are a lot of video cards left, which has nowhere to apply.
there is a possibility that he even used only part of the equipment.
People reason that the next key will be decided in January, February next year. But I think it will happen much sooner.
Now the reward is high and large miners have joined, so ordinary people have nothing to do here. In principle, it was the same with mining. At the initial stages, you can mine coins with a processor, and then there is nothing to catch there, since large players are connected.

EDIT: These guys don't need money, the same team solved puzzle #120 and the money of both remains untouched at 3Emiwzxme7Mrj4d89uqohXNncnRM15YESs

 Tongue

It makes sense, if @Etar is right in his calculation, that is at least 6 x 42U racks that suck some 80-90 kWh. Probably somebody that
already has some kind of business (industrial warehouse, proper power supply, etc) that makes good money, so all the expenses from the puzzle operation could be offset against company income and reduce taxes. No need to even touch the puzzle money.

BTW, congrats on the win! Well done.

I'm finished my own brute forcer that run all calculations purely on GPU (CUDA), I started some tests and looks ok but the challenge is to be fast as possible and actually it only can be achieved by using multi gpus.

next step is prepare it for multi gpus focusing on #66

if anyone with dozens of gpus woud like to TRY it, we can do a fair partnership to share the money.  Smiley
There are a few of such programs, first you need to link to your github page, make it open source so everyone can verify the safety, and in time if there is a need for improvement, other devs will improve it. 😉

A friendly message to @Satoshi aka puzzle designer ;

You owe puzzle solvers nothing, once they find a key and withdraw bitcoins out of it, the mission is accomplished, you can then reveal the private key for public, of course you could give them a month or so in order for them to withdraw those garbage coins out, if they decide not to, it's  because they don't want them.

We have worked as much as the solvers, even more so and we deserve to have a look at the keys we were trying to find for months, otherwise working on these puzzles is a waste of time for those not having lots of rigs to kangaroo the keys.

Since you know the keys and you don't owe the solvers, it'd be great if we could have #120 and then #125 private keys. Please.

It is probably high speed custom GPU's with lots of ram adapted to BSGS. To be honest I was surprised at how little BSGS under loaded my processor. In any event the finders have not pulled any of the alt-coins from the related addresses out. Maybe they found a pattern to the public key in 5 step and are focusing on just that.

and for the solvers of puzzle 120 and 125 we kindly plead that you publish the private keys of these puzzles respectfully. It is only fair to give us the keys for us to better understand the puzzle. Thank you. We don't need to know who you are if you solely choose to stay anonymous then that is fine. you could just create a random account and post the keys then you can go ahead to delete the account.

My guess is it's a lurker with large amounts of stupidly expensive GPUs such as A100.
Could be. But A100s are not as good as 4090s yet their costs are greater.

Will be interesting, if we ever find out.

  I will volunteer 190 GPUs minimum of A40 and I have a few numbers of 3090 too about 50 pcs of 3090 and 50 pcs of 4090 there are 45 A40s and 45 A5000s. I need the next instructions on what to do

If you have that many and can run them for the long haul, then we may need to just run #130 in its original range. I could run tames and you and others run wilds.

Agree about posting elsewhere (not just this place) I have discord and telegram set up.

If we/others can agree on a plan, I’ll put things into motion.

Agreed. Let's create the force. Let's join forces. No going back

Let's think before do something. We need to find puzzle #130 before the rivals.
Suppose they have 512 GPUs like 3090 (what they have 256 is exactly clear) in average they need ~306 days to solve #130.
If we reduce to range 2^119 bit and rent GPU we need 16 GPUs 3090 to solve 119 bit range in 306 day for every public key.
Price for 4x3090 $0.7/h or $67.2/d * 306 = $20563 Someone willing to shell out 20K for the theoretical possibility of winning?
Don`t forget that we should search 1024 public keys. So we need 1024 participants with at least 16 GPUs 3090 cards everyone.

Using tame and wild kangaroos separately is a good idea. Because we only need to generate tame kangaroos once.
Another point is that to launch only wild kangaroos, we needed tame kangaroos in an amount of at least x2-3 from the expected.
And the supply of tame kangaroos must cover the number of wild kangaroos for the worst case.
For 119bit expected op = 2^60.55 with DP size 27(~470Gb) need at least 2^33.55 Tame Dps to run only wild kangaroos.
I'm not criticizing, but just arguing whether it's worth starting at all without having the resources.
In fact, there are not many hunters here, especially those who have several dozen video cards of the RTX 3090 level.
Just reasoning.
I agree. Needs reasoning. Many people say they will do x y and z but then quickly fall off. I may just run tames in the 2^129 and if people want to run wilds, they can, and compare to my tames list. Or chop it down to 124 bit range (since I have many tame DPs already) and then people can run 1-32 pubs and try to find a match.

Or maybe breaking it up into 32, 128, 256, etc ranges would be better?! I’m on the fence.

well what if there are some of us willing to take that chance and all we have to do is join forces together. where do we start from and how do we start and most importantly how do we join forces so we don't make mistakes and communication cannot be only on this platform in case we need to share some funds.

We can use fraction-kangaroo or just a python script that will divide #130 puzzles into 2^20 pieces.
Each hunter will look at least for 1 key in the range of 109 bits.
What if we divide the pubkey by x amount. we will say divide #130 pubkey by 10; that gives us 1,024 pubkeys and reduces the range to 2^120/2^119.
I will run tames and then we just need 1,024 people (or less if multiple people run multiple pubkeys) to run wilds. I will post tame points (text files with all tame points) and then all who run wild points just need to verify if they have a match. If there is a match, we can share/split the reward. This way 2 people will share prize and people can run as many pubkeys as they want to.
We can decide on the best number to divide by, if interested.

Example tame points:
