Topic: Vanitygen: Vanity bitcoin address generator/miner [v0.22] - page 69. (Read 1153678 times)

Bitcoin mining is not hard either, it all depends on the difficulty. The bigger the set of chars in a vanity address, the bigger the difficulty

Why is generating a vanity address so hard... It's basically bitcoin mining after you get past a certain amount of set characters...

then if a quantum computer, does not help solve the fastest hashes, the only option would be to find a weakness in the elliptic curve generated by the EDCSA is that correct?

But from what I've read about this algorithm, it uses a random value generated by k, but random really.

Also I have to say I read about a weakness that affects wallets that are generated in Java, it is not impossible, but from what little I've read still relies on very robust protocols

Thanks again for your time, I just want to understand a bit more all related to btc

A quantum computer can not speed up vantiy address generation as its not efficient at sha256 or ripemd160 and thus can not calculate the private key from an address. A QC is not a very fast computer, it is capable of performing certain algorithms like shor's which is better at solving certain tasks. This does not magically enable it to do all calculations faster.


Similar to mining you make no progress towards your goal. Vanitygen just randomly generates a private key, checks if it matches the pattern and keep it if it does. If not the key is not stored. Considering 1 million addresses per second and ideal storrage (32 byte per priv. key, no overhead) you have to store 2764800000000 byte or 2.5 TiB per day. Thus you cant check for doubles. Even if you could, knowing the result of one round does not bring you a step closer to the solution. To make sure you have all solutions you have to try all combinations. For bitcoin those are 2²⁵⁶ private keys for 2¹⁶⁰ possible addresses.

I downloaded the most recent version from github and tried to install it on my Mac. When I enter the folder and do a 'make' then I got the following error:

pattern.c:32:10: fatal error: 'pcre.h' file not found

Any suggestions?

OK i see really interesting the possibilities of vanitygen we just miss one thing a quantum computer.

we work with a really big numbers so the possibility of a collision is minimal.

I just wondering to know how long will take discover all the address with the 11L pattern.

with my equipment i just get 1.000.000 of address with the 11L in 4 hours but not sure about the maths.

How we can scalate the efficiency of vanitygen i mind i can rent a supercomputer and put vanitygen to work (amazon cloud, google cloud etc)

if i put 10 grafic cards to work in the same motherboard all the power will be used by vanitygen?

why paterns as 111111 take longer than 1abc?

any chance to ad the rendezvous points to find more quickly the The Elliptic Curve Digital Signature Algorithm (ECDSA)

thanks for your time

looking for a collision"!!!!!!

Ignoring that it is no use to find a complete bitcoin adress. :-)

You can not put the whole bitcoin adress in vanitygen.
the adress is a base58 of a hash+checksum.
You will have unbase58; remove the checksum, then rebase58 and try and find that sequence.
When found, that checksum part will be regenerated by vanitygen when it presents the result.... in a couple of million years.


try:
vanitygen 1 -k -o test.log

As far as I know the flags cannot combined.

Go back about four or five pages ... and read the flaming manual! (That and use the


switch...

Great choice of Vanity addresses BTW, I have also generated some 6-character specific vanity addresses previously with the help shorena and Timelord2067. They might help you out too. Good Luck!

I can help you with this, but I need to know how the pub key is used in vanitygen.

/?

Can anyone help me creating 3 Vanity addresses starting with the following:

1. 123456
2. 111111
3. 111BTC

And here's my pubic key part:


Thanks in advance

BTW, are bitcoin addresses starting with numbers like this easily hack-able via brute force?

Really good the aplication i pointed 4 servers to the pool to help bit.

Now i have a question

1MPmZ99f52t8cYchJMcD19QqeZnwVo2S8v


I want to bruteforce this btc adress, I own already the private keys but i wanna do some test.

shall i introduce my btc address as pattern and wait for the solution?

Edit:

I wanna create thousands of btc address with vanity but something give me a error

vanitygen 1 -ko test.log

what im doing wrong?
