what kind of address is this?

https://blockchain.info/address/1111111111111111111114oLvT2

Is it a bot or some hack activity underlying it?

[jwinterm]

Looks like a burn address. None of the outputs are spent. So, people send money to in order to buy-in to some new project or something probably.

there's already an old thread on that topic

Normally the process of creating a Bitcoin address is:

1) Create the private key
2) From the private key calculate the public key
3) From the public key calculate the Bitcoin address

The Bitcoin address in question was created as follows:

1) Create a bogus Bitcoin address

Notice that the private key and public key were not created, and they can never be calculated or recovered so:

Any Bitcoins sent to that address will be lost forever.

Very interesting Bitcoin wallet.  May be a voting address.

No, it is simply the Bitcoin address that you get when you create a Bitcoin address from the 160 bit number

0000000000000000000000000000000000000000

That is all it is.

Why people send BTC to any address that simply burns it forever is another question.

Interesting indeed and no idea what is going on there, why do people keep sending money to it? The last transaction was sent yesterday and the address who sent the coins yesterday seems to be including that address in all of the transactions. Very odd..  There's more than 3 Bitcoins there right now and by today's price that would be around $700 and if no one ever finds the key to that address (which no one will)  that's $700 just thrown away for no reason??

Also, what's with this message "Unable to decode output address" every transaction shows that, what does it mean?

The address is a "burn" address, which is an address that is chosen by hand and has an unknown public and private key. Bitcoins sent to it cannot be recovered. Why people are sending bitcoins to it, I don't know.

The undecodable output is data that the sender is storing in the block chain. Blockchain.info just doesn't know how to interpret the data.

for me the most interesting weird bitcoin addresses is this one:
https://blockchain.info/address/1BitcoinEaterAddressDontSendf59kuE
the address (name in it) says it all.

making these sorts of bitcoin addresses without private keys is not that complicated. you just have to put together a series of letters and then correct the value that i think is called checksum or like that.

Check out all the outputs from this transaction:

They read:

There is a bunch of cool stuff written here:

But my favorite is the one that I created:

Which reads:

11SpeakersAtMyFeetAPairofXXTyrHor 0.00000001 BTC

11ALwaysPLayTheGratefuLDeadWdq4Xo 0.00000001 BTC
                                  0.00000004 BTC

Yes, the characters at the end of each address are the checksum so you have to take what you get for that part of the "string" when you create these addresses.

All BTC sent to all addresses created like this are lost forever.

I think that it was generated through vanitygen?
It has an option but this address the number of "1" is just to long.
The difficulty in this case would be so hard to generate, is it possible?

NO.  It is not possible.

These addresses are not generated by vanitygen.

Addresses generated by vanitygen have valid known private keys and public keys.

As stated many times, all of the addresses talked about in this tread do not have known private keys or public keys and never will.

[ashour]

It looks like a custom made address, it was probably generated with a javascript script. It is probably used for a burning process since non bitcoins have been spent.

[Yerm]

Normally the process of creating a Bitcoin address is:

1) Create the private key
2) From the private key calculate the public key
3) From the public key calculate the Bitcoin address

The Bitcoin address in question was created as follows:

Notice that the private key and public key were not created, and they can never be calculated or recovered so:

Any Bitcoins sent to that address will be lost forever.

wait, so the address doesnt have an owner?. that means if someone randomly created a private there's a thin thin chance they could end up with this address.

Your "thin chance" is at least one in 1,461,501,637,330,902,918,203,684,832,716,283,019,655,932,542,976.

So, NO.

If someone could end up with this address then they could end up with yours, or better yet an address with thousands of Bitcoins, right?

If you are going to randomly end up with someone else's address might as well dream bigger.

How can i have an address like this it's so funny to have one.
Also the outputs from the address that you mentioned.
How are these created, i know through vanitiygen its to hard at least for my rig.

[BurtW]

Again, they are not generated by vanitygen - that would be impossible.

The way they are created it to select a string you want to have, for example:

11ALwaysPLayTheGratefuLDead

Then calculate the 160 bits that will encode to that string by reversing the following calculation:

https://en.bitcoin.it/wiki/Base58Check_encoding

Then calculate the correct checksum and properly add it to the end.

It is not quite that simple but you can figure it out.

In my example the number 0007ccc123012ca1eefc2a65126de365965bfa6d encodes to 11ALwaysPLayTheGratefuLDeadWdq4Xo

Finally to record it in the block chain you simple send some Bitcoin that will be forever lost to the address.

[DannyHamilton]

NO.  It is not possible.
