Another 31 character bitcoin address

Hey, guys,

I have just discovered this thread, because I find the topic about different "self-created" addresses very interesting anyway.
I hope it's okay if I revive this thread, after almost exactly one year ago...
Maybe I am not the only one who has experimented, and new beautiful or funny addresses are to see here from others!

I recently took a closer look at it, because I really wanted to have an address fits to my username, by which one can immediately recognize that she belongs to me.  
Of course, this address is more a fun project.
Because this address is only used for forum purposes (highest possible privacy) and so far only entries are in it anyway.
As far as I know, these addresses are called "vanity addresses", because the owner has the private key for, i.e. has calculated them!

Here are a few examples from myself (from which i have private keys):

This is my personal forum address:

Of course it is important to know that these so-called "burn addresses" are usually only "compiled", so that they match the algorithm of Bitcoin!
But nobody has or ever had a private key for this addresses...
With today's possibilities, it would be almost impossible (for a private person), to calculate the key of such an address...
Whereby, I can imagine, that with "Google's Super Computer" something might be possible!

As far as I know, 5-6 characters after the 1 (which is always the beginning of a simple Bitcoin address), is the end for a normal private user...
I had read something about 3 characters more = ~3500 years time it can takes to calculate the key... blatant!  

For this kind of addresses I had already written a contribution, where also nice addresses were included:

Also an example which I've created   (without private key, but funded and immortalized in the Blockchain):

Very true - eight alpha/numeric take weeks and weeks to do - I have literally hundreds of words or combinations that I've searched for - alas I haven't had my graphics cards going for many months now due to the boxes age, but am planning on getting a new install with all new cards etc.

You *can* get custom ones that long done using split key.   As to price... I really would have to wait until I have a new box made up and see what kind of length of time a solution would take.

Bitcoin 101: your Bitcoins are only yours if you and only you know the private keys! You should never rely on a private key generated by a third party.

Nice 1, how much would you ask for it, if you were selling?
What else do you guys have?
BUMP

Well i saw transaction like this one:
4e6da853ca210092dc05b409cba70582d275519aa4176ce755e7b0c011c78933


As new year donation . Its pretty high level skill to do such transaction.
Its hard to show real cool transaction that happened actually. Not hard to write 1whateveryoulikeinaddresswhileItDidntEverHappenedf89w34

 Read the post directly above yours for the answer!

1YesThatWorksThankYouXhomervUVfQs!

I used the site you suggested for sha256, and this site for base58:
http://lenschulwitz.com/base58

Obvious, but just to be clear, this is only useful for anyone needing a burner address - you cannot generate the private key.

 You have to use the binary data rather than the string value.  Probably the tool you are using doesn't convert the string to a hex number so it will use the ASCII code for each character in the string as input.

Try this site -  https://anyhash.com/sha256 and make sure to select the hex checkbox to the right.

 

Is there a step missing between 4 and 5?

And as I understand, sha256(sha256(N)) would simply mean "hashing a hash" - correct?

000A52498DB787B09EEC7C428B8B0C853EA1C2702C (from step 3) sha256'd is:
414852558A27373137680508E28F0C3E35481EF766D72CDDFA27084EECBFFAA3
... and when this ^ is sha256'd I get:
3649A20CD93B0A51FDFFF9831E8DC4EBB9FE0883708D2969E79E70AE78FF51B1

Where does BD0F8969 come from in step 4, in this example?

I used this site to hash: https://passwordsgenerator.net/sha256-hash-generator/

That is so cool... thanks for that.

1) create a template of your desired address ie 1waLLobserverburnaddressxxxxxxxxx ^{(the last few characters will eventually be random due to checksum)}

2) Base58 unencode your burn address into hex - 000A52498DB787B09EEC7C428B8B0C853EA1C2702C4E117611

3) remove the last 4 bytes from the result and call what's left N - 000A52498DB787B09EEC7C428B8B0C853EA1C2702C4E117611

4) sha256(sha256(N)) - BD0F89693417148626446F3E1EA43A69453FBCF72A024600FB54A2BC34F23387

5) take the first 4 bytes of step 4 and stick it on the end of N - 000A52498DB787B09EEC7C428B8B0C853EA1C2702CBD0F8969

6) base58 encode step 5 - 1waLLobserverburnaddressxxy1oWwkk

done


 

Search for a burn address generator, this one for instance: http://gobittest.appspot.com/ProofOfBurn

How do you add a check sum? Might come in handy later.

I can hardly wait for a full address. Now it makes me want to keep trying on my wallet to be able to find a rare address for myself, but it's not possible now because it's all with the wallet that's out there. I have the first one (on my sig). So I sent some of my inactive CPUs (on my mining machine) to the task and found it in a few weeks.

Jesus, that must have taken forever to bruteforce, what kind of hardware were you working with? Must have been an absolute beast, or you simply got completely lucky and cracked one early with low power hardware.
