[ARCHIVE] Bitcoin challenge discusion

[iparktur]

It depends what expenses you have. I'm using my small rig to heat my home so actually it's paying itself by just generating heat. Everything else is just pure profit.

Just like the old days of mining Bitcoin.

I live in a warm temperate to arid area, so the excess heat is usually unwanted, except in the coldest parts of Winter. The temperature today is going to peak around 35 degrees C.

...surely there must be a more efficient way to heat your house? Your GPU is basically like a simple foot heater, so its efficiency is very low compared to something like reverse cycle A/C.

Good answer - I like it.

I apologize that my question is a little off topic.
For addresses that have an output transaction, people retrieve R, S and Z values from a  Bitcoin Transaction.
The process of obtaining (extracting) R, S and Z values from a Bitcoin Transaction is known and understandable to me.
Another thing is not clear - the practical application of the parameters R, S and Z. Is there a thread on this forum that discusses the practical application of these parameters R, S and Z?
And secondly, the 2coin.org resource often freezes and does not work.
Is there any other resource similar to 2coin.org?
Perhaps there is a stand-alone script or software option on GitHub?
Tell me.

This is the general principle of digital signatures. Having the private key the owner can sign any message (as well as the outgoing transaction). Signature of the message is a point. After that anybody can verify this signature with the public key.

Here is the general description:

Tell me.

What is your main goal? If you just need to take r, s values from raw transaction - you can easily do it. The structure of the transaction is described in the links provided earlier by me.
If you want to understand how these values are calcualted - the description is also in the links above.

For more details, google for "DER signatures".

Thank you for the advice, but It is difficult for me .
I don’t know how to work it.
Here, probably, you need to work in Python, but I do not know programming.
I need ready-made software, script or website.

As I understood, you need R, S, Z values from the raw bitcoin transaction. Just out of curiosity, what are you going to do with these values if you do not know programming? Tell your final goal - probably you need not signature value from transaction but smth else, and the advice here could be more helpful for you.

Do you want to extract the private key from a transaction? possibly get the private key from a transaction but only when the same signature (k) was generated in at least two different transactions. But all these addresses are empty for a long time. Having extracted the private key from the address with different signatures for each transaction is IMPOSSIBLE.

Yes, that's right - I wanted to test this theory of two transactions with the same signature. Just one person began to pass this method as his invention, but I found information about this method dated February 2018.

I honestly said here that programming is not mine.
Something I can do, but my knowledge is very small. It's too late for me to learn programming.

vimp666 - I don’t know what kind of programmer you are, but I’m 100% sure that if someone gives you software with the "get rich" button, you will click this button (just like me). And what's the difference between us ?

why programmer ? running python scripts is not so difficult. I’m not telling you what you need write a script.scripts on github and without us are enough.I think almost all transactions with the same signature are a blockchain android wallet failure (a few years ago), which for several hours produced the same value of (k).

I don't have python.
Even if I download python, I don’t know how to use it correctly.

2iparktur And why would someone just give you the "get rich" button that works only once for one wallet?
2vimp666 Not all addresses that have transactions with the same K are empty. But from these transactions, it is not possible to create the correct private key.

You have a very interesting position.
Imagine you are sitting on the chair with 1USD note sticked from the bottom. If you want this 1USD note you should get off your backside, stand up and take it.

Better write here your bitcoin address and promise to pray for the luck, and some lucky private key hunter will send you bounty once find the key  I guess you will have better chances.

[iparktur]

iparktur - "And why would someone just give you the "get rich" button that works only once for one wallet?"

This was written in the original post from  vimp666 in my address, but then vimp666 edited it.

vimp666 - "Not all addresses that have transactions with the same K are empty. But from these transactions, it is not possible to create the correct private key."

Well, why not try it?

At first :
I do not intend to beg alms !

Secondly :
I think that you are very much simplifying and reasoning from the perspective of a programmer. Try to teach some grandfather programming in any language. I'm talking about programming, not about working on a computer with ready-made programs (Word; Excel; clBitCrack, etc.)

This is a useless discussion and off topic.

Yes, this is offtopic here. The main topic is about 100BTC transaction challenge, but not about finding for reused R values (as I understood you want to scan transactions for R, S, Z values in order to find the reused random number).
In order to close this discussion here I just want to give you the link to related topic where R reuse discussions were made: https://bitcointalk.org/index.php?topic=581411.0

What do you want to know? Z values for known private keys in this transaction?
I have them.
