Vanitygen: Vanity bitcoin address generator/miner [v0.22]

Exactly. The "percentage left" is cut in half every x minutes, where x is the time it shows you for 50% when you start it.

This isn't making sence.

Are you saying IF a job were to take Five hundred hours to reach 50% it would take a further

• Five Hundred hours to reach 75%
• Two Hundred and Fifty hours to reach 75%
• D - Three Apples

If the answer is a further Five Hundred hours to reach 75%, (and half of 25 = 12.5% therefore 75% + 12.5% = 87.5%), would it be about (I said about people) a further two hundred hours to reach the next bench mark 80%? (not withstanding the 87.5% half of half of half of 100%)?

500 hours for 50% chance
500 more hours for 75% chance (1000 hours total)
500 more hours for 87.5% chance (1500 hours total)
etc.

I have been quite lucky, I found x8 that I searched for did take like 3 days to get them all but persistence pay's off!

As Missy says to me all the time...

Bonkers!

I suppose there's no point asking why it doesn't just make it a little more linear instead of exponential?

A chance to find something simply isn't lineair, as it will never reach 100% chance.
The chance always stays the same: if it's 500 hours for 50% chance, it's exactly the same chance after you've run it after a week. That's why you can just as well restart the the search at any moment.

Agree, i love vanity addresses so i studied on my own a lot. Because of that, i know you can restart your generation process how many times u want, and still have same chance to find address.

Just have a question. I don't have any graphic card installed and i want to do mining work on bounty pool but it gives me error OpenCl.dll missing which I guess is because I don't have any graphic card. So is there any way to do this work without having a graphic card??

You must have an onboard graphics card, right? My laptop has an onboard GeForce, so it can even be quite acceptable for vanity searching.
It's too slow though to be profitable for the mining pool, and if you're running CPU only, I doubt it will be worth your time and electricity.

[Velkro]

Well maybe there is, but it would be so slow that its not worth it. Currently there are many cheap graphic cards that could do the job for you.
If you will not "mine vanity addresses", you could switch later to mining with graphic card some alt coins. So depends on you how you want aproach it.

I want to run vanitygen and if address balance is not zero vanity tell me what may i do ?

when you run vanitygen it will create a new pair of keys ... so this kind of  problem should'nt never happend

 Not that you will ever have the opportunity but in the extremely unlikely case that this happens, only your conscience can tell you what to do.

It's much more likely to just guess Bill Gates' creditcard number, that's only 16 digits, and only numbers. Strangely nobody worries about that, but when it comes to bitcoin, all of a sudden guessing 70 characters seems like a possibility.

Yeah, I've been searching for a collision for like 3 years now, not a single one.

I would think that Electrum would be far less efficient than a purpose-made application that simply has a set datastructure designed for fast contains() operations containing all addresses with non-dust amounts (by searching the chain) attached to an iterated key generator would increase your efficiency (still extremely futile and not likely at all to find any collisions). Remember that people actually use the Electrum servers for real transactions they need to send and receive.

I am running a special made script through Electrum Python console that generates random Bitcoin addresses and then checks the balance on my local Insight server.

If an address has a totalReceived balance then it adds the address to the wallet using importprivkey(), will also send a pushbullet notification to my phone/laptop.

I still haven't implemented what I will do if I find a balance but I want to sign a message telling people where to contact me if this was their address.

If they sign back then I will refund the balance to an address of their choice as I don't intend on stealing from people.

It's well known that the odds of finding a collision are not favorable but I like challenges so I am destined to find one.

I should actually be counting how many addresses I have search so if I do happen to find one I will have a ratio to share.

I've been thinking about using machine learning to see if I can find a pattern in the key generation but I need to read more and I don't think there is enough storage to get even close to the amount of data I need to find a pattern.

[defcon23]

  yeah , i had already seen a runing script scanning the entire blockchain database to looking for non-dust amount .. and this script never got any collision too.. anyway that's always  interesting, as a challenge,  to try running these kind of scripts ,or better :  to try coding them ( in an ethical way, indeed  )  and, as mentioned above, only your conscience could tell you what to do in case of an "hypotetic"  collision ..

[Dabs]

The "pattern" from a previous "hack" targeted the random number generator, which was flawed. I don't think he looked for private keys, but rather he figured out the private key based on spent transactions and something or other ... he returned most of the coins to their owners.

Out of curiosity what kind of hash rate have you been getting over that 3 years? and how many addresses have you scanned so far? Also you say youve been looking for non dust addresses, does this mean youve found some with very small amounts?

thanks
