How do you know that it is impossible to generate a given point?

Do you have a proof that you reported it to the police?
I am not sure if there is anything YOU may do, but maybe police may contact chipmixers to ask if address belongs to them. If he left his IP it will be easier to find him. It will be difficult because probably it will be an international operation so it will require cooperation on different levels. Good luck anyway...

Maybe prepare/configure a hardware wallet and deposit at notary?
1784  Bitcoin / Development & Technical Discussion / Re: Help with 256 bit generator on: November 05, 2020, 07:41:07 AM
Hi guys I am trying learn the relationship between 256 bit encryption and bitcoins addresses and private keys. I remember something ages ago which showed the bits (256) corresponding with the private key. Can someone point me in the direction of such a resource.

Thanks

Maybe this:
https://btckeygen.com/
and sources for running on your computer: https://github.com/MrFreeDragon/VisualBTC


Or this: https://learnmeabitcoin.com/technical/
It shows the whole sequence of transformations: private key->public key->hash->address etc.

I have an electrum wallet and cannot remember the password.  I think I know the words i used though so can narrow it down. Could i use any of these things?

Do you know the seed? If yes - create a new wallet with the known seed.

If not: the procedure is identical like with wallet.dat files from Bitcoin Core.

If you suspect you know what could be the password - you may try to do it yourself.
(be careful with sites like https://www.onlinehashcrack.com/tools-electrum-hash-extractor.php)
Try to extract hash of password using the script from John the Ripper project:
https://github.com/openwall/john/blob/bleeding-jumbo/run/electrum2john.py

You should receive something like "$electrum$4*123456abcd...".
then you may use this hash with hashcat.

If in doubt - the best service seems to be https://www.walletrecoveryservices.com/ Email Dave, he will tell you what to do next.

I have a CPU, does 256 bit work? I need the full range to be a small probability of finding the key in a short time if I lucky

CPU? ehhhh

Dude, you have no idea how much 'luck' you will need. On the full big range this method is almost this same like randomly picking the numbers from 1 to FFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFE BAAE DCE6 AF48 A03B BFD2 5E8C D036 4140 and checking if you hit.

You think you still want to try?
Take 64bit puzzle and try to find the key - just throw 64 times coin and check if you find the key.

BitCrack should be ported for ASIC miners. That will change the game.

AFAIK it was already discussed several times - miners are not a good devices for hash cracking.

You've been warned, checking an address on list of address doesn't have O(1) complexity.

I don't understand what this means

i get like 100 address ?

dow can i dump with balance ?


Please, slow down. Think what you want to write and then use the full sentences, like in primary school.
Use google translator if you need.
For example:
"I have a Bitcoin Core wallet.dat with a 100 addresses inside. Is there a way to dump all the addresses with balance using one command?"

And then the answer could be: Check the manual of https://github.com/mikeborghi/pywallet or any other fork of pywallet.

Ah - and you may try to use google, duckduckgo, bing or any other search engine before you ask your question. It does not hurt.


Cheers!

1793  Bitcoin / Wallet software / Re: I forgot 6 words from my seed, any brute force tool ? on: October 06, 2020, 07:16:35 AM

The issue is that with each additional word, the problem becomes exponentially harder. If we use the benchmarks I described above, of 44 million years to crack 6 words, then it looks something like this:

1 word - 1 second
2 words - 90 seconds
3 words - 2 days
4 words - 10 years
5 words - 21 thousand years
6 words - 44 million years



Yes.... and no. What you wrote, is the time needed to check all the possible combinations of words, pessimistic approach. But in the real life it does not work like this. Retrieving the correct combination is not a 'reward' after the time spent on work. What I want to say - with these big numbers everything depends on luck, because it is possible that you will find the answer after 1 second - if you just hit the correct combination.

Hi guys,
Hope I have posted this in the right place. I just did a search and couldn't find an existing thread covering this.

I want to be able to buy a Domain Name and Web Hosting just using BTC / bitcoin.

I tried to buy a domain on NameCheap using Tor on Tails, but it didn't seem to like me just before the payment page, and sent me back to the previous page. I'm afraid I can't recall what the error said.

Any guidance would be greatly appreciated.


Did you try https://www.hostinger.com/payments ?
