Is this a late April Fools Joke? ![Huh](https://bitcointalk.org/Smileys/default/huh.gif) It's not joke as I used to copy some private key to test out. It shows the same address. At this moment, number is no important but management as one day, It will be cracked as tools are designed to be cracked. Whatever the author does, He just tells us if you don't follow the suggestions, then your precious may be stolen silently.

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 ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) . You'll likely witness the heat death of the universe before that happens. Here's some good reading about address collisions/exhaustion. https://bitcointalk.org/index.php?topic=3462.0;allhttps://bitcointalk.org/index.php?topic=27277.0;allhttps://bitcointalk.org/index.php?topic=26278.0;allIf 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 10 15 bytes. There are 2 160 possible BTC addresses, each of which is 160 bits == 20 bytes long. So to store all of them you need 2 160x20 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 10 35 addresses to find each spendable one. Suppose you can check a million addresses per second, this is going to take you more than 10 21 years. If everyone in the world is trying to crack this at the same time, it will still take around 10 12 years. And when someone finally cracks it, after paying the electricity bill for 10 12 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.

It is not the scam. Just a black humor to prove how bitcoin is secured by Mathematics.
The search text input is for searching Page Number ONLY. We have cancelled the private search text input in case people think that we will record the private key people entered.
It is scam. For example, 1) I visit page http://key.btc123.com/134384732473xxxxxxxxxxx294732473247968546 and import one of private keys on it to my wallet 2) I transfer some bitcoins to the address of this private key 3) You see the number 134384732473xxxxxxxxxxx294732473247968546 in your server logs and import ALL private keys from this page 4) Now you are able to steal my bitcoins. Profit! to all: NEVER USE PRIVATE KEYS FROM SUCH "DATABASES" FOR KEEPING YOUR FUNDS - THEY ARE NOT SAFE

It just list all the private keys in the key space. The site has a warning on it : NEVER expose or search your private key at any circumstance at any time. And this also means, if a private key is exposed, then NEVER use it. If we can benifit from this site, it is that this site increases the visiting users for site btc123.com, and in some extend advertises the new block explorer : b.btc123.com

I don't agree that this is FAKE. It is true. All the data is true. And a database doesn't have to store all the data if it can just display the data which the user requests. Besides, in a database not all the fields can be indexed and searched.

Besides, in a database not all the fields can be indexed and searched. It isn't a database. Using your (very loose) definition Google or Yahoo is a database of the entire internet (though they are closer to being so than your website). You're just using a sensationalist title to drive traffic to your website. If we can benifit from this site, it is that this site increases the visiting users for site btc123.com, and in some extend advertises the new block explorer : b.btc123.com

The site NEVER suggest visitor do so and NEVER guide visitor to do sth like this. "Do not think about monkeys". If you ask somebody not to think about monkeys - he will think about them It just list all the private keys in the key space. Create this list with javascript, not by server engine. And visitors will be safe to use it.

Who owns these addresses ?
Who owns any number? For example, who owns the number 983456928496583673940384? That's what private keys are - just very long numbers. Ownership of a bitcoin address is the result of the fact that out of a very, very, very large set of possible private keys, you have picked one in particular. The public key (and hence the bitcoin address) is very easy to calculate from the private key, but the reverse is not true. Indeed, the only known way to get the private key of a given bitcoin address is to try *all* private keys until you find one that matches this particular bitcoin address. This requires enough computing power to boil the Sun as the now famous graphic illustrates. Because only you know what that private key is, no one else can generate a valid transaction with the coins sent to that public address. Put another way, what you actually "own" is the knowledge of the particular private key can be used to sign transactions for your bitcoin address. It's like knowing the location of a treasure buried underground on an unimaginably vast plains. Everyone has "access" to the entire prairie, but without knowing the exact spot, no one can access your treasure, because it would take many millions of years of exhaustive digging.

Do the math :
If they store 1 bytes per page, they need 8,22752E+62 PETA Byte to store the whole database.
This is a scam, and whatever key you put in their input textbox surely recorded.
Exactly. 904625697166532776746648320380374280100293470930272690489102837043110636675 pages is impossible. Let's do the math to put it in perspective: assuming 99.9999% compression, at 16 kB of input data per page, you'd need 1.44 sexdecillion 1 YB (yottabyte) hard drives to store the data. Therefore, we can conclude that each page is being generated by an algorithm, not from a database. Therefore, it's most likely an attempt at Bitcoin theft.

HI, Not that it is really going to make that much difference A database is not 'magic' even with compression there can be a significant overhead in just storing the data, (record structure,pointers,indexes,disk headers etc)
Even if you don't need to store 16k of data per page……. just the secret key….. we all know (hopefully) that the public address can be re-generated from the secret key via an algorithm otherwise what is the point…..
A better way is going to be extract all addresses from block chain, sort them( plus date first used), then use a stat algo to see if there is any grouping, finally generate private keys see if it is in the 'range' of the grouping .. if so.. store for later. ( you require the blockchain rather than generate on your own kit as this would not highlight platform/implementation weaknesses in the systems)
