My friend, I didn't mention any binary. I said that he didn't provide the source code and therefore I don't know what he used to compile VBCr.exe in the end. Since I don't want to get his source code at all, I asked if he could recompile the code he has using os.random if that's not the type of random that the executable uses Simple, friend
The .exe file is a binary. I answered to the second part of your question already. Please take your time to check.
So there you go...yes, the binary for direct execution (.exe) can be compiled using the source code that the author has in his possession. What part of my question that my friend didn't understand? :/ and my original question was to the author WanderingPhilosopher and he should understand what I asked him, and he is the one who must know the correct answer to what I asked him, if he can recompile the VBCR.exe with os.radom from source offcourse If VBCR.exe was compiled with os.random for key generation, then everything is fine and I don't need it to do anything. This was my question from the beginning, but I possibly explained myself badly because I neither speak nor write English.

I still don't fully understand — if a low-bit privkey public key is exposed, how could someone potentially derive the private key from it? Could someone please explain how that's possible?
Brute-forcing using the public key is much cheaper than brute-forcing using an address only.
if he didn't use it, he could go back and compile an .exe with o.random.
This is not how development works. You can't just "compile a binary" after sticking "o.random" somewhere and expecting it to work.

Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it
Taking advantage of wallets 71 and 72, I'd like to ask WanderingPhilosopher - author of VBCR.exe - if he could release a compilation of the executable but with os.random, if he hasn't used this type of random. Is that possible, friend?
It does not look like it's using Python. Most likely it's C++ with CUDA. At least, the Linux version uses /dev/urandom, so most likely the Win binary is doing something similar.
Since his source code isn't available on GitHub, I don't know what he uses, but it must be C++ and Cuda. But if he uses o.random, then random character generation is fine. That's why I asked if, if he didn't use it, he could go back and compile an .exe with o.random.

for 18 characters import os random_bytes = os.urandom(9) random_hex = random_bytes.hex().upper() print(random_hex)
Since GPU farm is worthless, 71 has almost no chances of being solved this year. Maybe in next years, unless someone is very lucky or the price goes to 200k.
And about withdrawing the funds. Mara is the only option right now, either you trust it or not.
Once a transaction is confirmed by a miner, there should be no more funds in the source address that a bot or anyone else can resend at a higher fee, right?
´ This question actually makes a lot of sense because if we use a fee of 0.10014251 and withdraw 7 BTC to the new wallet, then why not use the mempool even with 71? Funds = 0 so there is no more than 1 RBF
I think this is a game that benefits others, not the solvers!! When more inventory was added to these puzzles, each Bitcoin was worth about $27,000. Have any of you thought about why the finder of puzzle 69 lost inventory?
Let me remind you of a few principles: Bitcoin can only consider a transaction as completed after receiving 6 confirmations in the next blocks in the blockchain network chain, and before 6 confirmations, that asset is not in your possession, and the block containing the transaction confirmed by miners may be completely removed from the blockchain chain before reaching 6 confirmations, which are called orphan blocks.
lost because he used the mempool instead of Mara. Big mistake when it's already been discussed here on how to avoid losing those funds.
Although using a private mining pool instead of a public one can prevent RBF, but who can guarantee that the private mining pool will not embezzle the money? This is not difficult at all technically. Normal transfers with high fees may still have a chance of success, but if they cheat through a private mining pool, you will never get your property back. I think the decentralization of Bitcoin does not allow you to hand over transactions to private mining pools. And I have not seen any evidence that No. 67 and 68 were successfully transferred through Mara.
If you have any questions, why dont you try Mara by yourself? Ill make myself clear: im not specialist in bitcoin not even in coding. But I already have tested Mara and it`ll worked out in the end. At no time in this process the private key is revealed, you only need a hex of a signed transaction which contains just numbers, and past it in Mara. I dont see how they could get the private key and trick you leaving you with nothing. I could be talking bullshit since im not an expert about all of this, Im just talking about what I did and tested with 5 dolars.
If I'm not thinking incorrectly, the assumption or theory behind not trusting MARA is entirely based on the hex of a signed transaction, the idea that someone there, whether it's the miner or someone else, could access the public key information before anyone else and, thinking "well, this is a Bitcoin puzzle anyway," could take the entire amount for themselves.
There only 2 way. Collusion inside 😅. Or setup huge mount of miner at mara pool and hope lucky the public key pass to your miner ..
But why .. .. better to find way to solve it 🙃😅
If it fail trough mara , then mara reputation will fall i think. Cause the solver will surely go bonker 🙃
My discussion is not about attacking or removing confirmed blocks for profit; it is about why some puzzles - whose existence is recorded at the time of their creation - become very valuable and popular, but when these puzzles are solved, the rewards are not distributed to the solvers and are stolen? The answer is quite clear: we all know that it is completely ridiculous and illogical to believe that bots can obtain the private key in a very short time, given the public key. The only logical and 100% probable case is that those bots already have that key before you yourself have access to your private key. "Yes, of course the number of these bots is the same as the number of puzzles left. These bots all have the keys to the puzzles and are designed to monitor and investigate unsolved Bitcoin puzzles and monitor Bitcoin transactions across the blockchain. If you have access to a full node on the Bitcoin network, you can examine the transactions associated with orphaned blocks at the time and date of previous puzzle solutions and see how many of these thefts occurred there."
Summoning KtimesG and nomachine. Let see their comment 😅🙏
And by the way, everyone knows that our company has a lot of computing power and cannot solve the puzzles in a very short time. So, have you ever wondered why it didn't do this? In the news and reports about our company's monthly income, it is stated that last month the company's net income was 900 bitcoins. In your opinion, why doesn't our company solve these puzzles so that it can earn more income than the previous month?
I am Iranian and I translate texts using Google Translate, and if there is a mistake in the writing, I am not to blame.
Cause for puzzle 71 it is gamble. Cost of bruting the entire puzzle is more than the prize in current technology. thats my opinion.
What if we send the transaction with Wasabi Wallet? Can bots still hack it? Does anyone have experience with it?
The secret to all this is that the wallets are low-bit, and the important thing is that the public key doesn't become public before you receive the funds in your new wallet. That's all. Don't make the public key public

at 1 bilion keys/s all range 4000000000000000000 to 500000000000000000 takes 12 years to scan it takes 24 years to scan if it is up to 5ffffffffffffffffff
I think you mean 9359 years. Unless of course the non-n00bz manage to break the hardware limitations via a combination of ideas and proper techniques (the 27th time's the charm) and crack open the lame mathematical limitations of the last 30 years..Or is it maybe of the last 5000 years? Or maybe since forever, and forever?
i know in sequential mode we need almost 100k GPU 5090 to scan all 400000000000000000:7fffffffffffffffff
lol i start searching today,using 4 Nvidia L4 each scanning at 335 m/k x to 312 m/k x sec is all about lucky? But i believe the key is around 7............ why because Puzzle 70 was done in 2019-06-09 and since then nobody have find the key for 71 how many people have being scanning for key 71 since 2019-06-09 so must be around 6....... or 7............ what do you guys think?
because nobody has scanned for 71 until 69 was found 70 was found because the pubkey was intentional leaked.. but the latest found was 69
That’s not true. I’ve been working on Puzzle 73 for months and have scanned everything up to prefix 14 from 1000000000000000000 to 14fffffffffffffffff. Higher puzzles like 71+ are absolutely being searched, even if they haven’t been solved yet.
comme on ) how long and what power did you scan from 10 to 14.. for puzzle 73 )
You know how it goes, share too many details and in 2 minutes someone calls you a liar anyway 😉 Let’s just say it took time, decent firepower, and good software. If you know, you know.
liar or no liar you wrote you been working on puzzle 73 for months and scanned EVERYTHING from 10... to 14... witch i think is bigger than puzzle 71 range so .... no need to continue
10 to 14 left 15,16,17...........at to 1F

Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it
Imagine you're trying to find a single specific grain of sand on all the beaches on Earth. There are about 2^62 to 2^63 grains of sand on all beaches combined. Puzzle 71 is like trying to find not just one grain, but a Puzzle 71 (2^70) = 157.4x Earth's sand. Even if you could check a billion grains every second, it would take you thousands of years to go through them all.
What if it is puzzle 135 and we know the public key?
The eternity of 135 is the same as that of 130.
Either everything is not explained, or eternity does not apply to the author of the discovery of the key to 130
85 seconds for puzzle 48, equivals to aproximately 45 years for puzzle 71 at, think about it
Your estimate is for sequential calculations within a range, right? The lottery is either a lottery or it never comes or it could be now because it doesn't follow any range only luck
It has been debated to death (and proved in all shapes and forms): "luck" is not affected if you scan either sequentially vs. some picked untested key (either at a random position, or via whatever other made-up logic, like prefixes).
What gets affected though, is the efficiency of the computations, and there is absolutely nothing currently that is known to be more efficient (e.g. that costs less or runs faster) than a full-on sequential scan. That is, if one wants to solve anything in the most efficient manner possible, not playing bingo with the elliptic curve and two uniform hash functions.
Well, I'm not interested in spending money on rentals to find a 71-bit key within the time I can live
That way I have fun and luck and chance remain with me.
I think the electricity company makes payment variations so that the consumer doesn't notice it too much. That way I know that I'll pay more or less within that amount, whether the AC is on or not, or whether or not an extra 3060 is on that must be it. My whole life has been like this... I'm 54 years old now and the electricity is always within those values, whether it's cold or hot. Im in Portugal..but i beleave is different country to country
You mean when they average monthly payments based on your full year's consumption? Yes, some of them do. In this case it's harder to track what you use even though you pay the full price anyway, right.
True. I have access to my monthly expenses in watts, but I confess that I don't even care about that anymore. In the winter I turn on everything I need to turn on to heat the house and in the summer everything to cool it down. My TV is also on 24 hours a day and I can't even sleep without it on. I think the TV helps me fall asleep. Well... that's how it is in my house... everything is on and I pay what I expect to pay... whether it's more or less than what I should pay, it's always within the usual amounts for many years This is all due to using my 3060 for these puzzles. I already used it for trivial PC stuff, but now it's in full swing looking for wallet 71 maybe I'll get as lucky as I did with wallet 48

At the end of the month, electricity always costs between $80 and $150. And when summer comes, it can reach $200 with the AC on in the room. I can made pay
Got it. I guess you don't load your PC all the way up if you pay between 80 and 150 only. If you do, that's like one more AC running all the time.

Toda a vida foi assim...ja tenho 54 anos e a luz é sempre dentro daqueles valores faça frio ou calor.
true...but it won't affect me at all whether I spend 100 watts a day or 270 watts a day. At the end of the month it won't be very significant. Of course, for those who invest heavily in this, I believe they need to do a lot of calculations to know if it will be worth it or not
When you crunch 24/7 using 3060, that's a way more than 270 Watts per day. Just the 3060 alone draws about 150-200 Watts, that's not including CPU, RAM, Mobo, Monitor, etc. If you use 3060 for 24 hours (a day), that's like 4000 Watts*h per day without including other components. 15 times more than "270 Watts per day". If you don't pay for your electricity or have a flat fee, that's different.
I just gave an example of how it wouldn't affect me because I've had my PC on for over a decade and have had several PCs throughout my life. I usually turn my PC on and only turn it off when there's a power outage or something breaks in the hardware. Maybe not everyone can do that, but as I said, I don't care if I pay 100 watts, 270 watts or those 4,000 you mentioned. At the end of the month, electricity always costs between $80 and $150. And when summer comes, it can reach $200 with the AC on in the room. I can made pay
