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.

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.

 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.

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.

  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  Smiley )  and, as mentioned above, only your conscience could tell you what to do in case of an "hypotetic"  collision ..

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

I average about 2 addresses a second due to having to check the balance against my Insight server, some times more depending on response time.

Scanned so far, billions, I haven't kept track.

I am looking for any address that has a totalReceived greater than 0.0, I haven't found a single one.

I probably won't ever find any this way due to the amount of possible addresses.

I have, however, found thousands of BTC addresses and keys by turning passwords into BTC addresses, brainwallets.

With the exception of brainwallets, generating a random address and checking the totalReceived or balance the odds are not favorable, at all.

So why do I do it? For fun, duh. And I am a persistent fuck, lol.

At 2 per second and only 31.5 million seconds per year, it'll be about 200 million checks in 3 years. Not so much, and indeed, very unlikely to find a double. Extremely unlikely. Impossible, I dare say Cheesy
I've read before that brain wallets are very insecure, when enough people use it, it becomes inevitable to have simple passwords, and brute-forcing you can find either one of them.
Finding thousands though is a LOT! How aren't these people all getting robbed?

Time is money my friend.

You can easily learn yourself.

Script to generate random Bitcoin address + Insight server.

It'll take you about 3 days to get the Insight server up to date due to blockchain.

That's if you are familiar with Linux and what ever programming language you choose to generate random addresses.

I considered making a "mining pool" for this but then thought it would be kind of sketchy, haha.

Interesting stuff. Think ill pull some resources and give this a go.
Its a fantastic way to provide that extra bit of security testing your own wallets just to be sure.

You say you have been testing this for 3 years with no collision?

What sort of hardware are you running that on?

Yes, 3 years, not a single thing.

To be honest, I may have hit one but I think I had it set to integer and the server returned a float so the application failed and yeah, lol.
