Title: Re: http://www.directory.io Post by: zestypepper13 on December 02, 2013, 07:10:40 AM 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 :-X
What does that mean? Title: Re: http://www.directory.io Post by: anti-scam on December 02, 2013, 07:17:51 AM 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 :-X 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. Title: Re: http://www.directory.io Post by: BadBear on December 02, 2013, 08:35:09 AM what the hell is this site, and how does it relate to the security of my bitcoins? 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. Title: Re: http://www.directory.io Post by: niothor on December 02, 2013, 08:40:41 AM I found https://bitcoin-checker.appspot.com/ which let me search for my private key and gave me a link on http://directory.io which contained it and my public key :-X What does that mean? Right , so right now i'm going to insert my "private" key in your website. Title: Re: http://www.directory.io Post by: BadBear on December 02, 2013, 09:46:35 AM Here's some good reading about address collisions/exhaustion.
https://bitcointalk.org/index.php?topic=3462.0;all https://bitcointalk.org/index.php?topic=27277.0;all https://bitcointalk.org/index.php?topic=26278.0;all 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.

Since people have trouble putting that in perspective, there are only 2^63 grains of sand on all the beaches of Earth. Yes, it seems it's a joke. Here is an interesting comment from reddit: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.

You'll likely witness the heat death of the universe before that happens. "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." http://www.reddit.com/r/Bitcoin/comments/1ruk0z/dont_panic_directoryio_thing_is_fake/cdr18tp Title: Re: http://www.directory.io Post by: terry205 on December 02, 2013, 01:46:26 PM 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 :-X What does that mean?

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. Title: Re: Post by: polarhei on May 03, 2014, 08:05:34 AM 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. Title: Re: Post by: Farmer17 on May 03, 2014, 09:50:56 AM So, what's the deal here? You can find exactly what the site is, if you read BadBear's posts above, or simply the last line in the posts.

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? Title: Re: http://www.directory.io Post by: DannyHamilton on September 17, 2014, 10:54:34 PM 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. Title: Re: http://www.directory.io Post by: no141 on September 18, 2014, 12:40:32 AM 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.

Title: Re: http://www.directory.io Post by: ironbit on December 14, 2015, 06:02:06 PM I know this, but it does not answer my question whether there is another similar service like directory.io :D
Actually, Directory.io is a worthwhile demonstration of how strong the Bitcoin protocol is. Your chance to find bitcoin in directory.io is almost 0. Maybe you could find bitcoin if you collect all private key there & use program to import those private key automatically :P More info : http://www.coindesk.com/bitcoin-protocol-hack-joke/ (http://www.coindesk.com/bitcoin-protocol-hack-joke/) Unfortunately, the site is offline and the cloud service shows an error message. Any good alternatives to directory.io? Generate bitcoin address by yourself in PC as much as you can ::) Or use online service and generate a lot of bitcoin address |
