Hello,

is it normal after 2 days and 99.5% prob to do not find anything? Or Am I simply unlucky?



  Yes and presently yes.
Are you looking for only one prefix or are you using a list?  Lists make better use of your processor time.


I need only 1 specific address that starts with 1+7 chars. 99.7% now :|

29 Mkey/s is a good result for a R9 280x? (Yes it's fucking hot in my room since 2 days.)

I'd say you're going to get it soon.  Wink

I've seen mine get to 99.8% but I haven't watched it enough to see it pass that.

Ok it's enough. I give up. After 99.9% the Prob section disappeared and it's 12 more hours since then without results Sad

I suggest to try again, but with options -i -k. This way, at least you get to see some results during the search.

Interesting, have you confirmed it can find an easy address like "1Sap"? 

If you ran up to 99.9% and didn't find it, technically you should find it within 50% of the next try.  It's additive over time and doesn't restart searching through the same addresses it did last time.

Yep I did that check before and It has been successful in 10 seconds.

How can I be sure it will continue the work on restart? Does it save some hash/stuff somewhere? I will try another 50%. I'll let you know

EDIT: Ok i'm a naaab. I did the check with CPU and it was ok. Then with OCL I have a lot of CPU/GPU hash mismatch and I didn't know it's an issue. with -S option it seems running well but with half of Mkey/s.

Ok. I will dig deeper over amd driver problems after my vacation. I've found some threads from 2013, is there some solution for current AMD drivers (Windows 10)?

Definitely could be an issue with the driver. As for "continuing" the work - it doesn't resume as you're thinking, my understanding is five identical machines running to 20% would be the same as one machine running to 100%.

It will never reach 100%.

Think of it as throwing a dice trying to hit a 6 four times in a row. You can stop and continue at any moment, previous misses don't need to be saved, you just start at random again.

 Past a few lines of output so we can see if there is a problem.
Code:
c:\oclvanitygen>oclvanitygen -d 0:0 -k 1Sapiens
Difficulty: 51529903411245
[25.70 Mkey/s][total 629145600][Prob 0.0%][50% in 16.1d]
The difficulty of 1Sapiens is very high for an 8 letter prefix because the capital S after the 1 has a lower probability of a match than other possibilities.  Based on one of my machines running @ 25Mkeys/s the difficulty for 1Sapiens (case sensitive) is 51529903411245 and I'm looking at ~16 days for 50% probability.  For an 8 letter prefix, you've picked a doozey.

I want to ask a question can someone with this vanitygen random generated addresses or any other generator while trying to reach the address he want end landing on someone else adderess and private key , so i enter my wallet to find someone had shared it with me and for sure spent my coins ??!!

i think i understand your question.. if you made a bitcoin address say 1btc or something, and used it, how possible is it to try to make that same wallet again?

the simple answer is very not likely.

while you can make other addresses start with 1btc.. you will never find exactly the same one twice.

So it's mathematically can but not very likely , i think it's just like we want to find each other in the ocean ...it can be done but needs 10000000% luck, is that right

I would say for sure that it's almost impossible. Otherwise, Bitcoin wouldn't be that safe anymore right?

"To obtain the same address, the result of RIPEMD-160 hashing would need to be the same. Probability of that happening is 1 in 2^160.

In simple terms, if you were testing against 500k patterns at 25/Mkey a second, it'd take about 25 quadrillion years to get a few collisions. Factoring out the randomness of course, as the nature of randomness entails that it could take 2 seconds or 2 sextillion years.

Even if you put all the calculating power of the entire bitcoin network on it, it would still take 10^12+ years."

Yes it does.

Just used yesterday actually.

 Yeah you could use AWS but use split-key generation to make sure that your key isn't compromised.
If you're going to do that, there are members on here who will generate keys for fees. It might be a little cheaper than AWS costs.
 I think Shorena does it but I'm not certain.

Understood, does it sit at 99.9% until complete or does the % go away at that point?

Alas, I would have a question. Starting from a private key, can you generate another similar address?

Let me give an example:

Suppose I have the private key of the address:
1PasqAbbbbbbbbbbbbbbbbbbbbbcgehnE

I want to generate another similar address:
1PasqRbbbbbbbbbbbbbbbbbbbbbcsaSgf

Can you generate it from the private key of the first address so you do not have to "generate" keys by causality?

Thank you

 No!  If it worked that way, Bitcoin would be worthless.
The hashing algorithms used are one-way functions - you would never be able to find
1PasqAbbbbbbbbbbbbbbbbbbbbbcgehnE base58 decoded is 0004456E03A3A379310A0DAB1718A3463EDD73E0436DC23977
1PasqRbbbbbbbbbbbbbbbbbbbbbcsaSgf  base58 decoded is 0004456E07D8524025C216494E6313E49A11D579A0CD20FA28

 Now you can take off the last 4 bytes (checksum) and the first byte (network id)
1PasqAbbbbbbbbbbbbbbbbbbbbbcgehnE; 04456E03A3A379310A0DAB1718A3463EDD73E043
1PasqRbbbbbbbbbbbbbbbbbbbbbcsaSgf;  04456E07D8524025C216494E6313E49A11D579A0

to get the public keys, you have to undo the RIPMD160 hash and then undo the SHA256 hash on each of those results however, there is no known reverse function for either of those.
Even if you could get the public key this way, the public key doesn't map to the private key as this mapping is also a one way function.
