The hash rmd160 is the same for almost all chains, yes you can derive the doge address from it the only change is the prefix byte.

i know it take milions years heh but it is good range ?

Half of the keys are in that range (actually is the half of the whole range)
3  Bitcoin / Development & Technical Discussion / Re: BitCrack - A tool for brute-forcing private keys on: January 07, 2023, 02:38:55 PM
how is possible that high puzzles already cracked in this high bit range

70 , 75 , 80 , 85 , 90 , 95 , 100 , 105 , 110 , 115

and why 120 and 125 and 130 unsolved

The author of the puzzles release the publickey by doing some small spending in those puzzles. Those were solved with kangaroo or some other tools. The 120 bit puzzle and above are really big and the cost to solve those puzzles is bigger than they worth.

BSGS mode is only for publickeys. That is why you get that speed.

For puzzle 66 is not possible yet because we don't have the publickey, with the publickey it will be solved in some 5-8 minutes in CPU.

I don't know anything about keyhunt-cuda, i think that program don't have BSGS mode but i don't know becuase i never use it.

BTW, NEVER run executables files from untrusted sources. My recomendation is always compile the programs from source code from the Original developer.

Regards!

i also can test keyhunt, if you tell me how to setup on windows and for #66 address. use python to keep track of your ranges, how to?

It is easy, make a python script to keep track of the ranges, and use os.system to call keyhunt with new ranges.

Regards.

But it doesn't have multithread, and it's not as fast as others.

The problem with multithread is that the output can be in different order than the Input file, if that doesn't matter to your output then it is OK.

Why you only need the output address or rmd hash ?

Regards!

I saved #115 on  0ctober 3rd the private key and timestamp and I never did find any other source before that, I may be wrong can I find the official record?

#115 ( 1NLbHuJebVwUZ1XqDjsAyfTRUPwDQbemfv ) Solved 16/06/2020: Priv=0x60F4D11574F5DEEE49961D9609AC6

You can find the timestamp directly in the blockchain

Interesting repository, I see some of my tools there but also some interesting codes, I will check some codes there because they implement libgmp.

Thanks
9  Bitcoin / Project Development / Re: List of all Bitcoin addresses with a balance on: December 24, 2022, 03:21:24 AM
Hi, I need Bitcoin Public Key Database with balance

I already ask if LoyceV has or can share that data but seem that it is a lot of work.

The best way is do this with an script, take your list of address of interest and get the publickey with an API if it is available.

Regards!

I have done implement parts of secp256k1 in pure asm

I would like to inform that perofrmence is fucking fast (for me):

100 000 000 performs modulo n on secp256k1 vals:

Can you explain what kind of numbers are those 100 Million inputs. What is your hardware and against what other implementation are you comparing your results?
11  Bitcoin / Bitcoin Discussion / Re: == Bitcoin challenge transaction: ~100 BTC total bounty to solvers! ==UPDATED== on: December 20, 2022, 09:29:44 PM
I just found 66

Good prove it making a signature here: https://reinproject.org/bitcoin-signature-tool/#sign

Consider speaking to a lawyer about your options. Remember that you are in charge - you do not have to deal with any of this if you do not want to.

I already talk with a lawyer, and he said that is a classic "I said, he said" without any proof of ownership those case are desestimed.

Hi guys sorrry for the late reply I was some busy in the work this week.

OP is actually a very experienced dev and Linux/FreeBSD sysadmin.

Well i know a few things but nothing special. But that is why a lot of users askme for some "help".

Someone who is regularly receiving extortion emails, offer emails like making you rich, emails from hot girls in craigslist, attention emails that your exchange is hacked, emails to receive free gifts and many more spams, will never react such way.

Those mails are handled by the Spam filter, it is rare for me to see it. In any case this situation was diferent it was someone that I was helping, I never imagine people going in that way shoting acussations without proof.

We're different people we'll handle aggressors using different ways. He's in a bad place it's affected him bad he didn't deserve threats or extortion.

Yes that is true everybody react different to this kind of situations.

I will be offline almost this week, im trying to get relax from this stuff, i get one week vacations from my job.

I was on vacations from monday 5 to sunday 11. That week was really a relief i stay at home and do workout, talk with my friends and do home stuff.

My stalker send me a telegram message (Already blocked) he is saying that i was on three weeks vacations, maybe he thinks that I was on dubai or something like that, looks that him is reading all this messages.



In any case since my vacations I already set a rule to delete all of his new incoming emails.

Listen M... If you are going to do something just do it, I don't care anymore, Proof your words signing a message with "your" wallet that will enough to proof your words (This is the link https://reinproject.org/bitcoin-signature-tool/#sign). I only will reply to you in this Topic

To everybody else thanks. I'm thankful you for reading me all this time. Thanks for the support.

...believe me these are all the collisions of #64

It is not a collision until all the 160 bits of the rmd hash match with the target....
15  Bitcoin / Bitcoin Discussion / Re: == Bitcoin challenge transaction: ~100 BTC total bounty to solvers! ==UPDATED== on: December 12, 2022, 09:54:02 PM
i think if 2 points on the curve produce first identical characters then its either a mirror or linear or diagonal or something

That is what you think.

Did you heard about the The Dunning Kruger Effect?

"First identical characters" means nothing, becuase it is the result of sha256 and rmd160 together. For that case you need first break rmd160 and then sha256 to be able to calculate the publickey for that puzzle.


16  Bitcoin / Project Development / Re: ecctools - a small collection of tools written in C on: December 12, 2022, 06:14:17 PM
I just add verifymsg to the reposity

This is a tool to help to vefiry the signatature of a bitcoin message :

Code:
./verifymsg -m 1E9YwDtYf9R29ekNAfbV7MvB4LNv7v3fGa -a 1NChfewU45oy7Dgn51HwkBFSixaTnyakfj -s "HCsBcgB+Wcm8kOGMH8IpNeg0H4gjCrlqwDf/GlSXphZGBYxm0QkKEPhh9DTJRp2IDNUhVr0FhP9qCqo2W0recNM="

The signature match with the address and it is valid

-----BEGIN BITCOIN SIGNED MESSAGE-----
1E9YwDtYf9R29ekNAfbV7MvB4LNv7v3fGa
-----BEGIN BITCOIN SIGNATURE-----

-----END BITCOIN SIGNATURE-----


Also it have some VERBOSE mode -v it give you the calculated publickey of the address, also the values RSZ for this signature.

Code:
./verifymsg -m 1E9YwDtYf9R29ekNAfbV7MvB4LNv7v3fGa -a 1NChfewU45oy7Dgn51HwkBFSixaTnyakfj -s "HCsBcgB+Wcm8kOGMH8IpNeg0H4gjCrlqwDf/GlSXphZGBYxm0QkKEPhh9DTJRp2IDNUhVr0FhP9qCqo2W0recNM=" -v

No matters, no pattern.

Exactly there is no pattern. Anyone can found some matches with some characters and the those aren't related to target address in any way.
18  Bitcoin / Project Development / Re: old Bitcoin addresses as 'NFT' on the Bitcoin blockchain - 'signature chain' on: December 11, 2022, 01:36:03 AM
albert0bsd provided a 2011 Bitcoin address 1H3TAVNZFZfiLUp9o9E93oTVY9WgYZ5knX to take part in the 'signature chain' project.

first seen transaction was on block 128,482  04/Jun/2011 03:54 AM UTC

Yes that was my first bitcoin address  Grin

It is a pity that i don't stake more bitcoin. Anyway lets to check the development of this project.

Interesting project
19  Economy / Reputation / Re: I have been subjected to harassment on: December 06, 2022, 03:11:52 PM
The lawsuit he has threatened is frivolous, and you have no cause for concern since his arguments are ridiculous.

Yes right now I am thinking the same

You also have every right to file a lawsuit against him for harassment. You should consult a lawyer before you take that step, but I think it would be perfectly legal and appropriate.

Well since I don't know where is he from, i think that will somekind of useles because that what mention in some other reply look:

Legal assistance probably will just waste your time and money, especially when you don't know nationality of the harasser.


Please take a break and don't think about it because you know you never did anything you've been accused of by the user.

Thanks you, that is what i will do, I ask for this week as vacations one month ago. I am more in calm now.

Do you think there is a possibility you are being threatened by someone not for the 'stolen' Coins but for developing keyhunt?  Anyone who could feel threatened by your tool and act like this to try and bring you down mentally?  Just a thought.

Interesting thought, it never imagine that, but i really don't know and there is now way to know that.

Mind sharing the date of your first ever communication?

November 11th



He knows your email address, forum profile. Does he know your real name, home address, bank account details or any sort of personal details or any of the person your know who is common between you and him?

Maybe just my name, i was careless i didn't notice that my email send my name in every mail, i already fix it. but that is some other point to me, If I am supposedly a scammer or a thief, why do I publish my name in my emails, why i should use my personal email insteat of some other fake email?

In any case i'm cleaning any PI from me and reviewing all my networks all this becasue i don't want this kind of harassment in the future.

Thank you all guys for reply, seriously the replies means a lot for me, it they give me more clearity on this stuff

I will be offline almost this week, im trying to get relax from this stuff, i get one week vacations from my job.

Regards!

First, thank you all for reply.

If it helps, you can post the addresses in question (only) in public so that the community can also verify that the address(es) are some random scammers' address via a website like https://www.bitcoinwhoswho.com/

The address is 1LfV1tSt3KNyHpFJnAzrqsLFdeD2EvU1MK

Yes that person claim to be the owner, that is very funny.

It's a random person on the internet sending random emails with random files. Why are you caring so much?

Well at the beggining I really don't care about it, but He start talking about some sue and he start to be more rude in his emails.

Check:



that email keep going like a bible...

And here is the last one, this last email pushme to  open this topic.



That "thank you and Kind regards" make me laugh a bit, but i was shaking while i read it


Honestly, I would take this very seriously and you should react as soon as possible and seek adequate help. No matter how difficult your current situation seems to you, it is certain that there is a way out of the problem. take it seriously, because obviously, this is your call for help.

Yes I've talking with one of my closest friends I'm more calm now. Thanks

if everything is as you say, it seems that you took the whole thing too personally. To me it looks like another way for fraudsters to get money. they don't care. ignoring is perfectly fine.

Yes, like I said before, at te beggining i don't care but I start to worry about it becasue his emails.

how would that translate into considering to take my life?

those are thoughts that sometimes appear, but I discard them and try not to think about it, that way out is for cowards and I am not one of them.

Do you know the alleged personality in person? Doesn't he reside in your neighborhood?

No, i really don't know where is he from.

Well, if they believe you moved the money in the wallet, they should be one ones to first make a thread against you here in the forum. If your life is not threatened, consider to ignore them.

I will ignore him from now.

Again thank you to all for reply.
