Topic: Bitcoin puzzle transaction ~32 BTC prize to who solves it - page 84. (Read 230098 times)

If the first transaction is set to RBF False, the second transaction has no chance of being committed if it uses the same inputs as the first transaction. This is because the Bitcoin network does not allow double issuance. So even if the second transaction has a higher fee, it cannot be committed if the first transaction is still in the mempool and has not been canceled or committed. The first transaction has priority in this case. Glad I could help

To steal something implies that there was a legitimate owner of that something. Be it a physical thing or intellectual property.

Now, if someone is stupid enough to think that they own information which is computable in a way that holds no patents or rights, then they very much deserve a lesson in what "property" means from a legal (social-enforced) perspective.

Now, do you understand what "public" means in the compound term of "public key"?

It means that some bits of information is known to everyone, and it is information that does not have any owner or rights attached to it.

Now, back to basics. Let us say you create a "private key" and you declare yourself as its owner. What rights do you have over it? ZERO.

Did someone buy the rights to use the bits 0 and 1 to represent information and we didn't get the memo?

There is no such thing as an owner of a private key. There is only the art of trying to protect a freaking mathematical number to remain undisclosed.

Now - did someone buy the rights to use numbers? Did someone bought an actual number, and has the legal right to be the single entity in the society that has the rights to ever use it? We didn't get the memo on that as well.

No one ever fought a class suit process because somebody else used some number they wrote on some piece of paper.

EVERYONE owns ALL the numbers that can ever exist. You cannot "steal" a number from someone.

But it is true that stupidity costs a lot. We have a saying in my country: the one who's stupid is not the one who ASKS, but the one who GIVES.

So, if you give out your number, and you worked a LOT to get at it, guess what? You never owned it.

Check out Etarkangaroo if you haven't, it seems to have some improvements, albeit small.

Max range width up to 192 bits and (on my setup at least) it's 1Gk/s faster than JLP's.

I have no idea if it's fully optimized but I'm guessing it could be a better starting point for further improvements, although one potential downside is that it requires PureBasic to compile, which has to be bought.

Steal a prize with RBF fee bump? Nah, I’m just making sure transaction gets there faster than a kid on Halloween running to the house giving out full-sized candy bars! 🤡

Amazing, and now you are doing setup to steal someones prize with RBF fee bump... ?

Believe it or not, I used Pollard's Rho algorithm to crack a Windows XP CD for the first time.

Running it on a P3-450  , it took about 19 hours.

The parameters were completely different, but the principle was the same.

There's no hashing for kangaroo, just plain point addition as fast as possible. Which translates to 256-bit arithmetic mambo-jambo.

JLP's kangaroo for example is definitely not fully optimized when it comes to this. But SHA and RIPEMD hashing were heavily studied and lots of hand-written optimized code exists, so the optimization upper bound is likely reached since long ago and nothing better (faster) is likely, just linear speed-up with better hardware. And even if it is, why the hell would one search for a key that, once public, is broken in a matter of seconds anyway? This is a logic fracture...

This is not the case with secp256k1 P + Q, since the longer the private key, the time to break it increases exponentially, but the computations are the same for any length. So it makes sense for scammers to try to convince naive people to contribute the results of some 256-bit mambo-jambo gymnastics (e.g. the bill they pay for running a GPU at full load) for their own benefit (e.g. build a msssively contributed kangaroo jump points database and simply scan for wild-tame collisions). A true non-scam collaborative effort would require that the finder of the key cannot know what the key is, and the owner of the pool cannot know what the key is, but that anyone can verify that the key is correct. So at spend time, a correct prize is distributed. So something like a ZKP protocol for miners.

I think the puzzles are the least problems of agencies, they definitely have access to special-purpose hardware that is beyond our imagination. If FPGAs to break RSA were already built in the 1970s, imagine how things look for them in 2024. We have chips with hundreds of billions of logic gates in our smartphones and call that high-end. How much processing power would, let's say, some processing "chip" that has the size of a basement?

It depends on how big the .BLM file is. If it is too big, it can take a long time. I think 16GB is enough for #66

I did take that into account.

Even with the -S parameter it takes more than one minute to load in with my machine.

In my particular case almost 2 minutes to initialize Keyhunt, 20 seconds for BSGS-CUDA.

Bitcoin wasn't very valuable back then. Also, no one bothers for 0.64 bitcoins and finally, the software, technology bots etc. at that time. It was not as developed as it is now.

There are currently 6.6 bitcoins, the reward is very high and the software bots are also quite advanced. Once Pubkey appears, there will be a lot of chaos.

Keyhunt does not take long to load, it takes a long time because you do not save the files.
If you add the -S command, your next run will take a very short time.

The 10 minutes is the average time and this is a pretty stupid circumstance. At this stage, the transaction has entered the mempool and remains 'Pending,' waiting for confirmation.

It only takes a matter of seconds to obtain the private key, after which you can replace the still-unconfirmed transaction in the mempool.

By using Replace-by-Fee (RBF), you can bump the transaction fee and forward the coins of #66 to any other address. RBF is a feature in Bitcoin that allows you to increase the transaction fee on an unconfirmed transaction, making it more attractive for miners to prioritize.

In summary, the logs for RBF transactions can be stored indefinitely or for a limited time, depending on the system's configuration and policies. If there are no logs - we can look into the glass ball what happened..

If puzzle 64 was recently solved, how to actually check if the puzzle in the end was drained also by bots or its the solver himself who got the prize?

If it was the solver himself who got the prize, why didn't the bots / scripts had gone in and taken the prize?

I cannot physically measure the benefits of this collaborative puzzle-solving. Who cares if it's 100, 500, or 1500 Mk/s? It's the same slow hashing shit, even with all possible fixes. Without something groundbreaking, it's a dead end.

They will work on it for at least two years, and eventually, someone will collect all the prizes using a bot script. It is likely that only resellers of cloud and GPU hosting will benefit.

And if some genius discovers something groundbreaking, do you think they will publicly open-source it? I'm not sure about their safety after that..Which comes to the next point... being slow is what makes them (agencies with three letters) secure. They don't want it to be fast.

I think for this purpose you could achieve even faster results by using BSGS-CUDA, if you can.

In my experience Keyhunt takes much longer to load in. With BSGS-CUDA; around 18 to 20 seconds to initialize.

Of course, it can vary from one setup to another. This is what I've observated with my rig.

Nice script, the people hating clearly have no idea what they are talking about. 

Yes, I have about ~4 Ekeys/s on PC with 64GB RAM.


But it's a blast to solve Puzzle 65, 66, 67, 68.  It takes about 60 seconds once we identify the public key from the blockchain.

Simple program for puzzle 66 below.

If you want to search from a specific private key number both ways up and down, just use it:


Here I set p for previous puzzle pvk and double it.
Middle is the variable from where the search will start.

Your K value should be around 3072 but if your working on puzzles 130 and above I would recommend using Etarkangaroo or another modified kangaroo because they find privkeys much faster with bigger ranges compared to bsgs.
The best way I think you could use bsgs would be to search in-between kangaroo jumps.

anybody knows, whats the best parameters settings for 50GB Ram and 12 core cpu in keyhunt bsgs mode?
