Let me explain you all guy how one can reduce bit size from 2^130 to near to 2^103.
First of all you just focus on how much bits are reduced? around 26 bits right (The first one can always be subtracted from pub key). So how big is 2^26? 2**26 = 67108864
So these are the pub keys in which one of the key is under 2^103.
The moment to try to go one single bit further, things are gonna get a little bulky.
The trick is simple, you have 1 public key, add generator to it and now you have two public keys whose private keys for instance are 89 & 90 or 534354234384847 & 534354234384848.
Why we do this? because we want to divide our public key to reduce its size and we don't know whether it is odd or even so add one to it and and now you have both.
Now you divide both and you have one correct result and one incorrect.
In second step you repeat the process of adding 1 to both of them and dividing 4 of them..
So this is like dividing pubkeys, 2, 4, 8, 16, 32, .... yep,, you got it!!

Nice to see this puzzle is still on going. It’s been years and I totally forgot about this.

So the conclusion until now is that it is only possible to crack the keys with brute force and no formula was found?

Was thinking to start working on this again but when I think of the amount of brain cells that are going to be destroyed I just shake it off.

What I could eventually do is provide some funds for funding of hardware or something needed.

Anyone thinks that with the help of some funds it can help to crack the case?

I can crack it with few funds, please enable me to do that,,, 1AfQHpdtZtMyf4F1H4CrVuvCwtX41rTxob

I've been using Core i7 with two 1tb hard drive. If can get a change to upgrade my hardware to a decent GPU coupled with eight 1 tb hard drives, that would be enough for me to hunt this puzzle down... Please ENABLE ME to. Here is my wallet address again 1AfQHpdtZtMyf4F1H4CrVuvCwtX41rTxob

There is no hidden formula here. BSGS  

Thank you for your interest in the ongoing puzzle and your willingness to contribute to the efforts to crack the keys. You are correct in noting that the current conclusion is that brute force remains the only viable method for cracking the keys. However, this does not mean that progress has not been made or that there is no hope of success.

Advancements in hardware technology have made it possible to perform brute force attacks much more quickly and efficiently than in the past. By using specialized hardware and parallel processing techniques, it is now possible to greatly reduce the time required to crack a key.

Personally speaking, your contribution could help me fund the acquisition of such a hardware, thereby accelerating the pace of progress and increasing the likelihood of success. With your support, I could potentially make significant strides in cracking the keys and solving this puzzle.

Furthermore, the potential benefits of cracking the keys could be significant. It could pave the way for the development of new encryption methods and security protocols, which could have far-reaching implications for the security of sensitive data across industries.

I deeply admire and appreciate your consideration and hope that you will choose me to support my effort at 15Y5kMbf8Niu6ALFMUhgP9x9RVcVoeBknm to crack the keys and solve this intriguing puzzle.

And BSGS is not a math ? it's all math here bro. 

No, for those we have Pollard Kangaroo, and they are math too

Puzzle 129, 134, 139, 144, 149, 154, 160 are already solved, this means that this puzzle is rigged, but anyway, is it harder to solve puzzle 66 than mining a block?
