Not here trying to toot my own horn...

I'm the one that first found 1BY8GQbnueYebq5d6CE1wDfbdAWWy33ZyW, sent it some change, and then sent that change to 67. If someone here is the one that gets 67 and you used the starting point I found and shared with you all, be cool and throw a coin my way, will ya?

Amongst the chatter in various Russian speaking Telegram groups, it looks like several 1BY8GQbnueY prefixes have possibly been found, but I haven't been able to verify any of them. Could be real, or not, but my hunch is that they're fake/disinfo. But I'm no longer monitoring those channels for updates, nor searching for 67, I've dropped out of the race... Thanks everyone and good luck out there.

I sent you a message.

Try, all math especially move from biger range  to smaller with more many pubkeys etc. No profit math in bitcoin bruteforce. Kangaroo description provide RogueCodee , JLP not say how select DP, without knowing how select DP right, you only spend time nothing also. If money interested, I think most profit is a join to private btc mining pool.

Very nice of you that you leave #135 for us puny plebs. Interesting though, none of the coins from #140, #145, #150, #155 and #160 have moved so far or am I only blinded by the overwhelming excellence of your pure math mind? Impressive... your achievement within only one month, show proof... I'm confused...

As albert0bsd said, sign messages or STFU!

It is easy to prove that you have the keys just by publishing a Signed text message that anyone can validate. So if you said that you solve these and you want that the users here believe you then you just need to publish such signatures.

Just like RetiredCoder did:



A lot of people here knows the math behind the ECDSA and right know the 2 best algorithms that we have to solve this have a complexity of Square root of N aka (meet me in the middle) [1]

- Baby step giant step
- Kangaroo (This one is the best because it don't have the memory limitation)

Hey guys, am new in bitcoin  and i discovered this puzzle about a month ago. Why are you guys brute forcing big numbers just wasting time, for me it just took me a month and now i already cracked 140, 145 150 155 and 160 by using maths, so you say no one  have discoverd the math behind bitcoin public keys?

Thank You all for your responses, I will look into this deeply before I start working on it.  Maybe we have to create another bot to compete with it as well, hehe

For what it's worth, Learning is Earning for me in the first place.

Once the public key of any puzzle up to say around 90-100 ish is out there kangaroo will solve it in minutes. It will not solve anything higher in minutes or even hours unless you're very very lucky.
People had been going at it for years for 120 and up.
The bots are run from users on this forum believe it or not.
One user on this forum in particular has the fastest bot in the world apparently i wont name them but just think about how the bots works and search this forum you will see for yourself.

Also mara is apparently the place to go to make a TX without broadcasting the public key.
There's a guide to it in this thread.
someone in this thread done a test and it worked. However that was with like $50 or so.
All the answers are in this thread.

From what I understand (correct me if I'm wrong), the flag is disabled by default. Miners would need to manually change the config file or something to enable it. Obviously, anyone who knows what they're doing would turn on the Full-RBF feature.

That's not really the point here, though. I'm not trying to start a debate about whether miners would set the flag of course they would. It was just a way of write  it, so sorry if it sounded dumb or confusing. Maybe it's just how it came out in my head since English isn’t my first language.

Why do you write "if the miners set the flag" for their node(s) to accept Full-RBF? They would be stupid to not enable Full-RBF for them by default. Every miner has a financial incentive to have Full-RBF enabled. I can't think of a reason why any miner or mining pool won't do this.

Do you have an example of a miner who doesn't?

It already was explained here is the post, but basically you need to trust to the Private service of Mara slipstream.

The main problem for those low entropy puzzles is the FullRBF feature of some versions of the bitcoin core, if the miners set the flag to accept TX that replace other TX without the RBF Flag

Search for slipstream.mara.com and you will find answers in this thread or the other one with 1000 BTC in the thread's title.

TL;DR is, you can't safely publish the withdrawal transaction where you expose the public key when you want to claim low-entropy puzzles after you managed to find the private key.

Bots will recognize your transaction, take the public key and find within seconds the private key with Kangaroo or whatever is really fast for this. They will then simply replace your withdrawal transaction with their own to their own address. Bots will compete against each other until some substantial amount of the puzzle's price will become transaction fee. Mining pools might participate in this race because they may benefit from the rising transaction fee that every Full-RBF replacement will cause.

Simple answer: you can't publish the withdrawal transaction publicly, you risk loosing the replacement race and thus the puzzle's prize.

How did he help him with the transaction? I have been reading this thread for quite some time but I think I missed the part about BOTs where someone tries to steal the sats after when someone withdraws the BTC.   Is there someone who can reply to this explanation of what really is going on?  If we really find out the private key then how can we claim it safely by not getting trapped by the Bots?

Yes my friend, thank you for your explanation.

The goal is not 1024 wallets anyway, there are 4 wallet in the target.
There is already a range close to 2**56 between these ranges.
But it is definitely not 2**56, there are even 2**52 in it.

My target point was 4, so I used 4, but my 2 target is very far. If you ask how I determined these targets, with a very old 7-year-old excel data calculation.

Example

147573952589676000000 = 7FFFFFFFFFFF9B300

147573952589676000000 / 0.5467 or 0.5468 / 2
134967946396264861898= 7510E7828155490CA
134943263158079736649 = 750B6C6E1D9664B49


no wallet will appear up to 160 bits in the calculation range above. 147573952589676000000 is an example.

68 Wallet
295147905179352000000 = FFFFFFFFFFFF36600 instead of this, 68 is definitely not in this range. 69-70-71..... none of them.

Obviously I am progressing with Decimal calculation. Then I scan them with a certain numerical combination.

I forgot to give another example, sorry.

13zb1hQbWc3MrSxUhXkXQCb5JVCwASfZZR
Hex: 2E394A6F45691482A
Decimal: 53292403858936514602

13zb1hQbWc3UCetc7A7EvAGSVxiL1QWifS
Hex: 2E37B9DF452FEAFCD
Decimal: 53285357088854159309

Decimal difference is 7046770082398210 - average is around 2**52-53.

In puzzle #67 there are approximately 1024 keys that start with that prefix (approximately), statistically every 2**56 bits it is repeated, so if you want to find another pattern you should subtract or add 2**56 to the private key of this one and look near that result, among one of those 1024 ranges, is the desired private key (probably), then what I would do is discard the 2**56 before and after that pattern because it is unlikely to be there.

this is pure statistics, but it is not crazy to try, as Einstein said "Insanity is doing the same thing over and over again and expecting different results."

130 bits wasn’t solved in two months. It’s just a psychological trick he’s playing on people like JLP and Zielar or many other who also have access to hundreds of GPUs. He’s just playing psychological tricks on them so they won’t work on the higher range and cut down his competitors.

This topic is increasingly reminiscent of the rat race movie. maybe it's worth stopping and starting a dialogue and rallying to achieve the goal? I don't have the ability to properly set up a kangaroo. but, there are people who can provide a lot of GPU. for the price of electricity. suggest options...

It's technically possible to solve 160 by tomorrow if we start today, as long as there are enough GPUs in existence.

But yes, one of the issues with RC's claim is he used 500 to 1000 GPUs in just 2 months (500 was the overly optimistic case of him being extremely lucky (much more luckier than just his method working as stated) AND without considering any DP overhead AND with using his super-double-fast-than-possible CUDA kernel no one thinks can exist AND assuming his entire distributed system worked perfectly without any bugs, issues, etc. which is always unlikely in the real world). There's better chances winning the lottery than achieving so many advancements in different problem areas.

So, the issue here is that the smoke could be easily lifted on him, because it's not like an every day customer (or employee?) that seeks out renting/"managing" hundreds of GPU instances for months in a row.

Someone who wants to lose his tracks would do it over a very extended period of time, with fewer GPUs. This would also make the attack cheaper, because of spot prices & price per teraflop decreasing over time.

If someone calls this jealousy or being a cry-baby, maybe they should put on their glasses. Creating a curtain of smoke is part of the game, you should think about what's under the curtain, and I think it is about extracting information, under the sense that it might no longer be useful. Don't be fooled that psychology is not part of a very interested organization's toolbox.

We have no hate against anyone's success—in fact, we genuinely wish him the best and hope he breaks the world record for solving #135. But let’s not forget that he’s the one who started all the trolling and later deleted his messages to avoid the backlash.

1. How when the bot got the pubkey was able to find the secret number in seconds?
2. What is the secret number [46346217550346335726]?
3. What are the DPs?

sorry for the trivial questions, but I am new and still trying to grasp some terms and how they are related to each other
thanks
