701  Bitcoin / Development & Technical Discussion / Re: BitCrack - A tool for brute-forcing private keys on: November 06, 2023, 08:12:33 PM
Hi guys,

I was reading this thread and found it interesting. Just a few questions get in my mind:
What if I find a zero-bit privkey address? How long would it take me to find a private key for this address, knowing only the address? Is it a million years, assuming that I don't have a public key?
Can you show us what you mean by zero bit private key? If it has "zero" bits then how can you derive an address from it? But there is a solution for you, it's not related to zero or 256, you can find 2^96 different private keys for every single address out there, under one condition, you'd have to brute force 2^80 keys to find one collision.(in theory)
Without public key, only having the address and knowing the exact range, you can go ahead and try puzzle #66, even if you halve the range, you'd still need to grind 2^65 keys.😉

found a way to reduce 1/6 total range.
python proto give a nice result for all known PK.

hope CUDA version will be a nice with 66..70 profit.

good luck!
Hi, who are you talking to, do you need someone help you cross the street? 😂

Since you cared enough to share your achievement verbally, could you be kind and tell us how did you managed  to reduce the range for an unknown key? You know sharing is caring right? But if you found a way to do range reduction for public keys, let us know about it, we might find some useful hints.😉

It looks more like coinmarket computer traveled in time, since if you go back in time and buy/sell Bitcoins, everything would appear normal for the rest of the world.  But if you wanted to go back, you could go back to 2009 mine alongside Satoshi and hide some information from now inside a block like an encrypted message, then you could decrypt it in your own time to prove you time traveled. Time flows in one direction which means you can't physically move to the opposite direction unless you are in quantum realm.

But yes it's possible for electrons inside atoms to jump back and forth in time, not that computer that generated the chart though.

Am I understanding this correctly that you have found seed collisions? Because I see different seeds with the same key as output, or is this something else?
This is not a collision. The one that was used is saved. With the -r 1 option you can select the fastest one.
If we get lucky.  Grin

I'm still unable to understand the process, what does it mean selecting the fastest one? Ok, let me get this straight, you are generating what, private keys from a seed? I wanna know how is it possible to generate 1 key from 2 different seeds, this should be impossible unless you are not using random, or you have just changed the key generator, but still doesn't explain how these 2 seeds generated the same private key:
Code:

As far as I know, importing mining equipments without permit is illegal, if they catch you, they will confiscate the goods. Mining requires a permit to avoid exploitation of electricity consumption, and when you get a permit, you can use industrial electricity with export price, I haven't heard that you have to sell to the government, I mean why would you even want to mine if they force you to give up your coins?
707  Bitcoin / Bitcoin Discussion / Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it on: November 05, 2023, 09:37:34 PM
Should add seed to be written in Results.txt
Code:
fprintf(f, "PubAddress: %s\n", addr.c_str());
fprintf(f,  "Seed: %s\n", seed.c_str());

Something like this. So that we can reproduce the same result Grin
Experiment with the least significant bits up to 2^30, which seed is more suitable in terms of solution speed. I like your ideas  Smiley
Added new code to mods on Github. Saving Seed to the Result.txt file.
Then run with the -s option
Code:
VanitySearch.exe -stop -t 1 -bits 28 -r 1 -s 45730C0CCA52F09AC21B00E4ADA360E9709152473494E91DFD74B6E11938BF30 12jbtzBb54r97TCwW3G1gCFoumpckRAPdY
The installed SEED works if the -r (rekey) option is present. Updated.
Without the -r (rekey) option, the start key is selected with the -start option.
file Result.txt
Code:
Seed: 45730C0CCA52F09AC21B00E4ADA360E9709152473494E91DFD74B6E11938BF30
PubAddress: 12jbtzBb54r97TCwW3G1gCFoumpckRAPdY
Priv (WIF): p2pkh:KwDiBf89QgGbjEhKnhXJuH7LrciVrZi3qYjgd9M82GSgY8p5EkUe

Priv (WIF): p2pkh:KwDiBf89QgGbjEhKnhXJuH7LrciVrZi3qYjgd9M82GSgY8p5EkUe

I want to ask, will the amount of smerit given to the merit source change every month? I see that there are differences in the smerit that the merit source has every month. What makes it different? Is if the smerit doesn't run out, will the next month's smerit be reduced?
You can read everything about merits here, if I remember correctly whatever you send in a month you'd get back the same amount the next month, Maybe I'm wrong.

I never can understand my monthly source supply.I am a merit source. I give a lot of merits. I also get about 200 merits from members in addition to my source.

Also my source merits seem to stagger in rather than 50 say on Nov 1 then 50 on Dec 1
Yeah, when you spend something like 10 today, you will get back around the same amount at around the same time if that hasn't been changed. I guess you answered the question correctly. Thanks for your contribution as a source.😉

Because it was a community involved quest; to find the fastest python code to gen and write to a file, 1 million addresses.
Not everything is about the puzzles/challenges.

One could say what is the point of providing a bunch of info on add sub div without concrete examples, from start to finish with result, but some do it anyway.
I know it was a "community challenge", I was wondering if it has any significance to nomachine's code when you said 1M address.
Also do you remember few month back when I could find public keys similar to #125 key? Well I will tell you this but it's not going to help you or anyone else.

Here is a new angle to work with subtraction only, try to subtract #130 from end range to get this :
Code:
0308360beeb0177961b04eccc33decdf63e23d205abc8ef6355d659d1313459ba7
Now if you just subtract 1 from it:
Code:
026a0747b3229f32ce2f0f7bd77a7bd306f6c95d27e7c5bee22a417938d9988605
Now if you add it to #130, you will have :
Code:
03e067911ebf6bacf87a8088ab9344c95843aed80b070eed09f9d947c98dfc0249
00000000000000000000000000000003ffffffffffffffffffffffffffffffff
Now if you subtract the above instead of 1, you get this:
Code:
035dee726b0fe623224fa1f4d79af66a9a1829213ec675875c619266a5f184e7d1
Once again, if you add the above key to #130, you won't get 1,  instead you are actually adding -1 of #130 to #130, you can confirm that by subtracting it from #130.

Ok, why did we get a different result in our first addition? Because we just subtracted 1 from our offset the first time, so no -n result, but when we subtracted a larger key than our offset, the second addition should have given us 1, but why it added -1 of #130 to #130? Because I knew which key was greater than the other, but if you subtract the larger key > 3fffff..... from our offset, the second addition would have resulted in G.

I don't know why I'm explaining modular effect here, this is useless, unless you know a few tricks.😉
712  Economy / Reputation / Re: Should Ratimov be in DT1? on: November 05, 2023, 06:14:59 AM
OK, but to be fair I took a look at the first page of your sent feedback, and you've left negs on people for promoting closed-source HW wallets, which I find to be inappropriate.  A neutral might be fair, but why in the world would you give a red trust to somebody for that reason?  Account selling, fine.  You and I both agree that can seriously affect the forum in a negative way, but I'd suggest reevaluating some of the red trust you've left before complaining about the red trust you've got.

I recently added DaveF to my trust list and I see that he was one of the members who negged you.  I might have to take a look into that.
My ratings won't show, so it doesn't matter, but since you mentioned it, they were promoting a phishing/fake wallet/link, that's why the topic was removed by mods. About DaveF, you can read his original reason here, but recently he did it again, to defend "forum members", just a typical bully, you have to deal with bullies with brute force, just like what happened here, but even though I don't think OP's main concern is to punish a "cheater" or trust abuser, this is deeper and you have to find the root.

Otherwise why nobody else tagged Ratimov for trust abuse and plagiarizing on top? Why are most of the DT members refrain from tagging other DTs for reasons as trust abuse, "trolling" "harassing"? Because of the possibility of retaliation.

No worries though, I have no official complaints, God willing sooner or later their wealth will hang on my reputation, how they say it? If you spit upwards, it lands back on your face, or something like that.😉
713  Bitcoin / Bitcoin Discussion / Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it on: November 05, 2023, 04:23:40 AM
That's something.
1 / 0.00011618 = 8607 Keys/s. But in fact it is more. To reduce measurement time, you need to generate more than 10,000 hashes in a cycle, preferably tens of millions. Then the measurement time is not actually counted, and the result will be more plausible.

Redo the wheel, nomachine, LOL.

citb0in has already done benchmark tests on fastecdsa, iceland, etc. generating and writing 1 million addresses to file. They have a whole thread dedicated to the test.
What is the use of saving a million "addresses" to a file? Can we not see any more base58 encoded addresses mentioned ever again when we are talking about brute forcing puzzles? Base58 used anywhere, whether to generate vanity or find a puzzle will slow down the speed by at least 5%.  Now imagine if we could instead increase the speed 5% more, difference would be like saving $100k from $1M.  Or for example if you could spend $50k to solve a key in 6 month, with 10% more speed you can save $5k.

These small numbers/percentages might sound insignificant for most people, you can only appreciate them when even 1% means millions to be saved.
714  Bitcoin / Bitcoin Discussion / Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it on: November 05, 2023, 12:38:40 AM

About ~30x faster than normal ecdsa in python Grin
Why only 1 hash? 1 hash can not determine the overall speed, if you want to see the actual speed rate, you'd have to benchmark your code by going in a loop, set a range and generate 1 billion rmd160, then check the time, after all you are going to generate trillions of them when brute forcing. Base your upgrades on bulk generation of hashes, if your speed is 100M/s, 2M more or less is not significant. 5M, 10M? That's something.
715  Bitcoin / Bitcoin Discussion / Re: Compilation of fake/unsolvable puzzles/challenges on: November 04, 2023, 09:27:25 PM
There is one legit/solvable puzzle which actually has a purpose and that is the 1000BTC challenge, solving that has some meaning  behind it, The rest are just distractions, useless because they don't contribute to advancing the science.
So far all the evidence suggests that we are dependent on very old algorithms to solve DLP, and the 1000BTC challenge will hopefully contribute in achieving new algorithms/formulas to solve DLP faster. This will of course help to keep decentralization of money strong so it could last for many generations after we are gone.

716  Bitcoin / Development & Technical Discussion / Re: the dilemma of division in ECC-secp256k1 on: November 04, 2023, 07:17:42 PM
You don't necessarily need to brute force all the possible values of n, you could figure things out another way, but the complexity could be much more, because when we are dealing with unknown numbers, we have to guess and try almost all the keys.

However sometimes there are some relations where we can use to our advantage, this is just an example:
I used 20 decimal precision for the following :
Code:
226918604445/47 =
4828055413.7234042553
1/47 =
0.021276595744680851064
1/47 * 34 =
0.72340425531914893618
Target/47 - 1/47 * 34 =
4828055413

No fraction, if you want to know more about the possibilities, you have to do experiments with numbers. If you can do the same with other numbers, finding how many times you have to multiply n/x to reach the fraction for other numbers being divided, and if you can create a table of say 1 billion keys, then you could in theory divide many different keys by different numbers and start subtracting from them and you might find of the 1 billion keys while doing your subtraction like 4828055413.7234042553 if you have 0.7234042553 saved among the 1 billion keys, subtracting the bold part could solve a key when you land on 1/47 * 34, though this is just a demonstration.
717  Bitcoin / Bitcoin Discussion / Re: What are the odds of guessing someone's private key or seedphrase? on: November 04, 2023, 07:20:20 AM

A total Bitcoin private key is 10^77 and the total atoms in the universe is 10^80.......snip.......
You need to open a Pandora Box with super luckiness to find a Bitcoin private key.
Who says BTC keys are 10^77? Secp256k1 elliptic curve group order is :
Code:
N = fffffffffffffffffffffffffffffffebaaedce6af48a03bbfd25e8cd0364141
If you add this to N
Code:
14551231950b75fc4402da1732fc9bebf
You will reach 2^256, and nobody can count the atoms in the universe, even that estimation is around 863 times greater that 2^256, but that's not the point, also pandora box only brings misery and despair if you open it, not luck.
The only physically possible way to find a private key( other than taking it by force ), is through working on public keys, and guess what? Public key cryptography is counting on the difficulty of doing that, it says "here I'm open in the public, throw your best at me" and it is safe because throwing the best is proven to be difficult to do, SO far.

I didn't send my findings to you, you obviously have a bad grudge against me, that you make me look like a hacker or a thief!
You are a thief who took another person's email, added a number and thought you were clever. The sewing needle also thought it was sharp and smart, it was in this thought that the thread went into its hole...
Ok, for clarification, I never contacted you, one day I received a PM from you asking me to join telegram and whatnot, I said share whatever you have here, then you sent another PM with your email address asking me to email you, which I did, then after a week and after a few email exchanging, you asked what type of file is more convenient for me, THEN I said if you want to send any file, upload it on a file sharing service on the cloud.
After that you said some bs about my email address, which is totally irrelevant because you don't even know me and I never gave you my  name etc, so accusing me of impersonation and theft is a shame on you not mine.
Now if you have nothing to hide, why don't you share your findings here for all to see?
Remember what I said about whacking anyone touching people's coins? Now thread your needle carefully.😉

@WP, lets not give "Diagran" a chance, after all people in here should know a few things about modular operations to know that won't work, at least not that simply.

hi "nomachine"
It is not possible to send private messages.
Please email me if possible.
To anyone doing research, working to find solutions etc, please remember not to open any file sent over email, always use precautions to avoid getting infected. I'm not insinuating anything here, this should apply to all matters. As this is a safety precaution. Anyways, good luck.


Good luck everyone with your spam free, troll free thread.😉
720  Bitcoin / Bitcoin Discussion / Re: What are the odds of guessing someone's private key or seedphrase? on: November 04, 2023, 12:40:33 AM
The system always has ways of generating a Bitcoin address and a private key in such a way that even if 100 addresses are generated in a day with the same wallet app, it can never give an address with the same private key.
The system you are referring to actually has the ability to generate almost all the possible addresses, I'm just not sure exactly how many addresses a master private key can generate, but deterministic wallets which everyone is using nowadays are useful for that they can regenerate all your addresses by feeding them with the correct seed phrase.

And even if you could generate 100,000 trillion trillion addresses per second, it'd be possible to see the end of the universe than generating the same private key twice.

But theoretically you could generate 2 different private keys unlocking the same address after generating 2^80 keys.
