People win all the time because the chance to win is equal to the number of tickets sold. It's not rare that someone wins, it's rare that you win.

Then I misunderstand the Powerball, because I'm talking about matching the numbers randomly pulled. Your chances of matching random numbers would be unaffected by the random numbers that others have chosen. Their "guesses" do not make your guess any more or less likely to be correct. Again, I might not understand how lotteries work I guess, but this is how I understand it. How are the chances equal to the tickets in a lottery of random numbers? More tickets makes it more likely that someone wins, but it wouldn't make your chances vary.

Quote from: LoyceV on June 10, 2018, 01:45:31 PM

When comparing Bitcoin to the Powerball lottery, I think it's safe to say you're more likely to win that lottery without buying a ticket, than finding a collision on a private key.

You're over exaggerating, unless we're operating on the assumption that you can win with a stolen ticket, or something? I do see your point though.

It's easy to confuse a theoretical chance with a real chance.

Apparently, because I do not know the difference. I've thought on this for hours and I cannot figure out the riddle. Help me understand theoretical chance Vs. real chance, genuinely, I am interested.

Example: You can randomly generate my phone number, call me, and tell me my creditcard number. Although this sounds far fetched, it's still 1461501637330902918203 times more likely than finding a private key collision.

Show your work for this math problem. What are the odds of me randomly generating your phone number, credit card and catching you at a good time for a phone call? Wink

Since I'm illiterate on vocabulary and semantics, collision = randomly generating a previously randomly generated Private Key, right?

Quote from: LoyceV on June 10, 2018, 01:45:31 PM

That's why it's very important to generate your private keys at random. If your random isn't random, someone else can reproduce it.

Humans are almost as bad at programming random number generators as they are typing random numbers.

Pretty awesome, no?

It would be pretty awesome indeed, if this private key wouldn't have been published 10 months ago already.

How very curious. Because that short blog post doesn't mention WHY they use that private key in their example.

What's cool about this one?

It received 21 ETH from the genesis block! Check the first transaction on the blockchain (link above).

How did we find it? Wordlists, math and blockchain APIs (our own scripts).

Pseudocode:

keccak-256sum("ABC123*") = 64e604787cbf194841e7b68d7cd28786f6c9a0a3ab9f8b0a0e87cb4387ab0107

(* The phrase is actually NOT "ABC123", but you should be able to reproduce this one quite swiftly, with a basic wordlist.)

From there, it's two relatively simple operations, including elliptic curve, to derive the public address.

Pretty awesome, no?

I'm having an existential crisis right now. Maybe it's because I have a poor understanding of math, but the chances of winning the Powerball lottery are something like 1 in 300 million and it happens all of the time. Statistical improbability does not equal impossibility, in fact it's tangibly the opposite. I could type random keys on my keyboard and potentially end up with an old Satoshi address at my disposal. The chances that someone pops a Private Key increases each time more people are attempting to do so, and increases exponentially when any of these attackers is using a method more effective than simple random generation or brute-force. Sophisticated hacks have a better chance than these figures would suggest.

Did any of you try to access wallets by guessing the seed? I think it might be easier to create a program that randomly checks various seed combinations than trying to find a private key with a positive balance. As time goes by there will be so many seed combinations that a modified password guesser linked to a dictionary might do the job. And this time if you'll able to find something it might not be a single address but a bunch of them. You might even get lucky and get into a wallet owned by a treasure hunter like yourself Wink

Electrum has a dictionary size of 1626 words and uses 12 of them randomly, producing 1626^12 possible combinations, which is close to 10^38 combinations. Good luck finding a collision. It will take quite a while. Example:

If somehow could test 1 billion combinations per second (arbitrary number I just came up with), we need 10^(38-9) = 10^29 seconds to try them all. That is approximately 3.17*10^27 years.

The universe has existed for about 13.8*10^9 years.

You see where this is going... right?

I think that the last few words are a checksum, so your chances are slightly better than that (but still impossibly low).

No, what they talking about (in this thread) are those neglectfully stored wallet.dat files, private key backups, paper wallet images or other forms of backups which potentially have funds.
History can tell that some people are stupid enough to store those (not only wallets but passwords and sensitive info too) directly in the internet without "hiding" the files with a disguised file name, file type, etc.

Winning a big lottery also has a small chance, you will never know unless you try. The numbers do not work always like that, technically you have two options you can find one with balance or not. Why there are doing this? Because they can.

The vast majority of the privkeys I've discovered are NOT from brainwallets (i.e. weak SHA256 hashes). Image search for QR-codes was nice for a while though, but those days are over. I have a couple of other techniques that I'm fairly sure anyone else hasn't thought of.

Every privkey in my database corresponds to a BTC address with at least two transactions on the blockchain. I throw away all "empty" privkeys.

I have a large Bitcoin Core wallet containing all my discovered privkeys. Five smaller transactions happened within the past week.

Anyways.... I was thinking maybe someone here has the same hobby as I do? Care to hook up and share some thoughts and strategies?

Nice thread, I'm a treasure hunter myself

And yes, like everyone here i know is 100x time more possible i end up fucking scarlett johansson than actually finding anything by bruteforcing.

I have however, found some keys with balance using unconventional methods. Thats the key (no pun) to find private keys. Methods come and go (Bruteforced brainwallets for example). Lots of other methods are dead and so will be a lot more in the future, just a matter of innovating!

Right now i thought, for fun, to develop a script to do old school bruteforcing, shooting in the dark without any specific order, just to see what pops up.

I began by running directory.io clone on a vps, modifying it a bit to display keys so a python script can pick them up and compare it with around 2m known addresses with funds. This beta version is doing around 6000 kps (keys per second) so its quite trashy at the moment, as it does around 500m keys per day

Currently modifying it to:
use 100% cpu, its using barely 30% atm. Multiprocessing, etc.
Convert the golang script to python so it can generate/check on the fly instead of retrieving an html page with the keys
Once this is done, modify the script to become a sort of botnet/pool that can check and upload to a server once it opens in a computer.

The funniest thing is that even that way, i wont find anything Grin

!!!

I then guess you are aware of the Large Bitcoin collider. At the time of writing, running at 673.11 Mkeys/s. They've found a few collisions. The odds are not in your favor, diplomatically.

Pure bruteforcing is a dead end.

Think of ways that significantly reduce entropy is my tip. There are a number of ways. People have posted a few, and I have come up with one or two methods myself. Overall however, mining is still much more profitable than going after dust* bruteforce-stylee.

* Yeah, MOST addresses with a positive balance on the blockchain contain dust, hardly worth the effort.

I managed to scale it to 1Mk/s with some tweaks on a few spare vps's I have, they aren't doing anything so is not like im investing on it or anything, it was a fun project to make though. I'm aware of the LBC, i ran it for a few minutes but preferred to make my stuff instead ;P

But of course, its better to find human-fault keys. I have had luck with ETH keys too

You see where this is going... right?

Of course, but it's the same when you're trying to bruteforce a private key. The combinations are endless, but that's not what this is all about. Nobody is trying to test all possible combinations, but find a couple that are in use and give access to active wallets. There's a quite high possibility that if you'll start picking 12 random words out of those 1626 and start messing with them in different combinations you will get a single hit. Isn't that what those "treasure hunters" are hoping for?
Why did I ask about the seeds? Because finding a single one can lead to unlocking a wallet with multiple private keys instead of a single one which the collision dudes are trying to find.
