I found [malware removed] which let me search for my private key and gave me a link on  http://directory.io which contained it and my public key  

What does that mean?

It means that you are trying to scam dumb people into giving you their Bitcoins by entering their private key into a shady site.

I'm not sure what the purpose of that site is, unless it's a joke. It isn't a database (that would be impossible), it's generating the pages in response to queries. So possibly an attempt at a scam, as in you look for your private key, and the holder of the list uses the generated pages to narrow down the possible addresses that have actually been used (there are 2^160 possible addresses, or 1,461,501,637,330,902,918,203,684,832,716,283,019,655,932,542,976). Since people have trouble putting that in perspective, there are only 2^63 grains of sand on all the beaches of Earth.

The total number of bitcoin addresses in use is so much smaller than the amount of possible addresses, that something like this is completely and utterly useless, and it would also be trivial to expand the number of possible addresses in the future. I laughed when I saw that website, cause I just know people who don't know the math are furiously putting page numbers hoping to find one . You'll likely witness the heat death of the universe before that happens.

Right , so right now i'm going to insert my "private" key in your website.

Here's some good reading about address collisions/exhaustion.

If every person on Earth makes ten addresses per second for 20 years (2x10¹⁸ total addresses), then the probability that two of these addresses collide is about 1.57x10^-12.

A committed individual or organization could easily aquire network storage in the Petabytes.  I think that would be more than enough to get a sizable operation started.

1 petabyte is 10¹⁵ bytes.

There are 2¹⁶⁰ possible BTC addresses, each of which is 160 bits == 20 bytes long.

So to store all of them you need 2¹⁶⁰x20 bytes, which is 29,230,032,746,618,058,364,073,696,654,325,660 petabytes.

Bear in mind, we are not looking for a single address among the clouds here.  We are looking for -any- address containing BTC.

Suppose each of the 7 billion people in the world has 1000 unspent addresses. On average you would need to try more than 10³⁵ addresses to find each spendable one. Suppose you can check a million addresses per second, this is going to take you more than 10²¹ years.

If everyone in the world is trying to crack this at the same time, it will still take around 10¹² years. And when someone finally cracks it, after paying the electricity bill for 10¹² years, they might be disappointed to find that the key unlocks just 0.05 BTC from the Bitcoin Faucet. Even if it's ten million bitcoins, it's not going to pay the electricity bill for 7 billion computers running for a trillion years.

In short, don't worry about it.

Yes, it seems it's a joke. Here is an interesting comment from reddit:

"I'm the owner of directory.io. This isn't an attempt at a scam. The first entry isn't "fake". It is the a private key with the value of 0. The next private key is 1, after that comes 2 etc.

The original thread has not been deleted. It is right here: http://www.reddit.com/r/Bitcoin/comments/1rua34/all_bitcoin_private_keys_leaked/

All of these keys (apart from 0) are valid. It is simply a joke. Remember when you've been told that it is almost impossible to generate a key-pair identical to somebody elses? This is a visual representation of that improbability. Look how many pages there are!

The original thread covered the fact this was a joke pretty well. No need to pretend this is a scam."

There is just one page and A simple function to GET value (page number) to PK.

You don't need the hellish amount to record all. It only shows how strong the system is. Even I have tried to deploy an experiment for searching private keys with wget's trick, still too slow.

Your best bet may be vanitygen.

[polarhei]

So, what's the deal here?

You have a little chance to get private key from public key known.

I have deployed experimental shell scripts to test out. It looks like I will have to find a way for searching many CPUs before perform reasonably.

Interested? PM me for details.

You can find exactly what the site is, if you read BadBear's posts above, or simply the last line in the posts.

In short, don't worry about it.

Sorry for digging up an old thread but how can we be certain that this many bitcoin addresses exist if we are not able to generate and store them? Are most bitcoin addresses just theoretical?

[DannyHamilton]

Sorry for digging up an old thread but how can we be certain that this many bitcoin addresses exist if we are not able to generate and store them?

A bitcoin address is simply a number between 0 and 1.46X10⁴⁸ represented in base 58 with a version number pre-pended and a checksum appended.

We know they all exist in the same way that we know that all the numbers between 0 and 1.46X10⁴⁸ exist even though we are not able to generate and store them.  That's the power of mathematics.

(In reality, I'm not sure that it's been proven yet that all possible values between 0 and 1.46X10⁴⁸ can be generated by the RIPEMD-160 hash function.  As such, while the addresses "exist", it is possible that some of those addresses have no associated private key and therefore any bitcoins sent to them may not ever be spendable)

Are most bitcoin addresses just theoretical?

In the same way that most numbers that nobody has ever counted to are just theoretical.

[no141]

I was just joking, but I have really have thought about the possibilities before. It's a really bad comparison, but someone always eventually wins the lotto, so no matter the odds, things can get lucky like that.

[Remember remember the 5th of November]

Now I'm scared

Nope, now you just proved you have not read enough about Bitcoin and just how big 2^256 is, or even just 2^160.

[no141]

And now you've joined my ignore list.

Plonk.

Now I have to wonder how I qualified for such a placement so simply.
