Not by using a random number generator.

no

What's the public hash of the address you found?

Even with everything that everyone says about hashes, we did get a duplicate GUID one time where I used to work. It caused major issues but from everything we could investigate, we really did get a duplicate. It's the only place where I have used GUIDs where it has happened, but it did happen once.

Nobody believes me and I have been called a thousand names on forums for mentioning it, but I can assure you it happened to us once.

A SHA256 collision is billions of times less likely than duplicate GUIDs.

i have been running a random number generator for over a week, over 100 hours and hit 1 wallet with $4.13. it might take a million years to target one address but there's not just one out there.
the only thing i have not done is log the private key that had cash in it the program just keeps running. but i will be changing that soon.

If you really hit an address, please make a big post about this and let people analyse it, unless there is some bad random number stuff / low entropy stuff like brainwallet involved this should not have happened.

why would i do that.

i started out thinking no way that this was going to work but then i had a hit. it might be just luck but its still running so i will wait and see.

edit its been running for 183 hours.

Why? It's a potential security exploit in bitcoin. If people abuse it before it gets patched, it's over.

If there is some random number generator insecure, then this is seomthing that could costs people millions.
(and even worse for the unlikely case that Bitcoin addresses aren't secure enough)

Care to share the generator for analysis?

Still, there are only 2^160 possible addresses from the 2^256 pool due to RIPEMD-160.

Sorry for hijacking, but I have another newbie question.

https://en.bitcoin.it/wiki/Technical_background_of_Bitcoin_addresses

If 2 different hashes at step 2 produce the same hash at step 3 (which is theoritically possible, although very unlikely, I know)
Then the final base58 address would be the same, though the ECDSA keypair would be different.

What happens, then, if someone sends coins to this address?
I'm guessing both ECDSA key pairs would be able to spend those coins?

It was just luck.

If someone wins lotto 4 times in a row that may happen, but you still want to analyse if there is any flaw in the system.
Especially the random number generator used in this case.

This is not possible. Sorry to disappoint you.

Yes it's 100% possible to build a generator.
Yes it's possible to hit a jackpot with it , but chances are 0.00000... my fingers hurt... 1%

Second , people like to cling on that 2^256 , which is not quite right.
Let's assume for instance there are only 10000 combinations. And the most advanced supercomputer is doing 1/second Cheesy

.
John has password 1823 , Jerome 5674 , and Maya 7777.
Well , it didn't take 10000 seconds for their passwords to get cracked right?

Same with passkeys , some will be safe till the dinosaurs are hit again by an asteroid , thousands of them are cracked right this second.
Also , do you know the amount of passkeys is not equal to the amount of addresses? Cheesy

Just a though about how secure your password might be.

Still, there are only 2^160 possible addresses from the 2^256 pool due to RIPEMD-160.

Sorry , I think I read above in this thread 2^256 and took that for granted without even thinking back.

It will take forever to ... what? Get them all? yeah! Get a few of them ? it's a nanosecond job.

If it was that easy, someone would do it.

Got to https://www.bitaddress.org , bulk wallet and there you go... you can generate 10000 adresses.
Chance on getting one with some bitcoins hiding there , close to 0 , but it's still a possibility.
It is not impossible.

That's incorrect. The private keys have so many possible combinations that it would take pretty much forever with the current processing power. That's as far as I'm acquainted with the subject.
