Thanks for the info. We already know what his script is doing, and still discussing it because:

Option I: We are all the same person as Ritual & Evil-Knievel, or we are different persons but we are in this scam together;
Option II: We are sado-masochists who love to waist everyone's time and money;
Option III: There's something very interesting in Evil-Knievel ideas, and we would like to talk a bit about it.

Pick your choice.

Is it on-topic, though? The topic of this thread is "OpenCL Based, Optimized BTC Private-Key Cracker", and it opens with misleading statements like "who knows, this tool is giving you good chances to get one of these lost 10 MILLION US$ accounts."

Those are alarming claims for people who care about the security of the blockchain.

Meanwhile, the tool (while it is clever) has no more chance of cracking a real key in the wild than a doorstop. Nobody disputes this, not even Evil-Knievel, who wrote it.

The logical thing is to close the thread so that it's clear to readers that the cracker has no practical use, there's no threat, and the security of the blockchain has not been compromised. For example, I was directed to this thread from somewhere else, and it took me considerable time to gain assurance that everything was OK. It's always possible to create new threads for other discussions.

Where did you get this number?  It looks wrong to me.

Sorry, you're right. Copy/paste error from a Python shell! prezbo gave the correct number.

The number I posted is the total number divided by 2560000000 -- in other words, 1 over this number gives you the probability of ever finding one of Evil-Knievel's so-called "weak" Bitcoin addresses in the wild. Practically speaking, these addresses are just never gonna happen.

For Evil-Knievel's demonstration to work, you need to use his pseudorandom number generator (PRNG): https://bitcointalk.org/index.php?topic=421842.msg4746108#msg4746108

His PRNG only generates from a set of 2560000000 possible values: https://bitcointalk.org/index.php?topic=437220.msg4809894#msg4809894

Meanwhile, there are 45231284858326638837332416019018714005014673546513634524455141852155 115792089237316195423570985008687907852837564279074904382605163141518161494337 possible Bitcoin keypairs.

The probably of his tool cracking a real public key, in the wild, is virtually zero. You are more likely to have a meteor land directly on your house, on the same day, four years in a row.

Evil-Knievel is insulting everyone's intelligence, wasting our time, and trying to con somebody out of 2 BTC.
