If I had a business and had to give a public address to get payments I guess it would be cool to have a vanity address so people can pay there, but then this address would need to split those payments into different addresses to make it more anonymous. I wonder if this can be done.

That's one longshot of a hope.  Imagine that I have a vanity address with one of those real word prefixes that this person has "squatted" on.  [...] Finally, why would the squatting help? [...] Why not just wait till someone else sends something there and then move those funds?
The way FirstBits works (or worked - it still works, just very few services support it) is that it looks for the first occurrence on the blockchain for the given prefix.  The only way it would appear on the blockchain if a transaction was made that fits that particular P2SH.  That's also how it is 'squatted' - you can generate 1word... all you want, but there can only be one 1word... that was the first.
There's pretty obvious extensions to this that would enlarge the address space and make it slightly less squattable - but FirstBits et al have gone way out of vogue Smiley

Well I was lucky to get this address while playing with vanitygen, I specified it to be Case-insensitive but the first address found was all lowercase besides the first character

I was going to make it Gr33khut but it would have taken much longer. So I now have a 7 Character (technically) case insensitive vanity address. my new personal wallet.

NEW: The example address

1xxxxxQkSqe6x1EnkG66ayMavz2cYV4zA

5JgkDpbk9ZrC42nFGhJoKj7k4w5v4b5hyWtR8dZvDKWNDUPhzam

Ha, I got totally confused by this one.  I thought you were trying to hide the address but showing the private key.  I was like "wtf, doesn't he know that the address is derivable from the private key?"

I dropped the private key into ku (https://github.com/richardkiss/pycoin) and what do I see:

Code:
Bitcoin address              : 12NugbnkyENs8iUEW5TzbzVZHAyvgY6LnS
Bitcoin address uncompressed : 1xxxxxQkSqe6x1EnkG66ayMavz2cYV4zA

Lol at me and a really fun address.  Now I'm wondering who's found the address with the most leading xs.



that is my entry with 5 x's . took less than 6 hours on my modest hardware, so i'm sure someone can top it.

Oh yah, I forgot that he connected it to firstbits.  I know how that works and I understand the connection now.

 Nice!  You had some luck too.  I've been trying to make my nick on and off for some time now but I can't get past the second x and that's using case insensitivity.  I'm either going to have to shorten my nickname or purchase another video card... or two Wink

 Nice address but it's not hall of fame worthy.  It isn't so difficult to generate addresses with just the leading 1 and the rest letters.
You can do plenty with a CPU - try this:  vanitygen64 -k -r "1[a-zA-Z]{33}"

Will I be able to search for prefixes using these options? Would this work? -k -r "1[a-zA-Z]{33}" -o [folder] 1Test

No

-r and unspecified are mutually exclusive.  You can do -r 1Test[a-zA-z]{29} though. ( Keep in mind that there's also shorter addresses, so you may wish to specify a range, rather than fixed 29)
-o requires a filename output, not a folder
-o and any other flags should be specified before the pattern, not after, or they'll be assumed to be part of the regex

 Well you would have to reword the regex search to "1Test[a-zA-Z]{21,30}" because the bitcoin address could be 26 to 35 characters in length (just in case you found a short one).  It wont be fast because you have to match the "1Test" string exactly.  Start with something easier to test it out like

 
Code:
vanitygen64 -k -r -o file.txt 1T[a-zA-Z]{24,33}

you can add more letters after the T but then shorten up the length like this

Code:
vanitygen64 -k -r -o file.txt 1Te[a-zA-Z]{23,32}

also you can check for case insensitive matches of first part like this

Code:
vanitygen64 -k -r -o file.txt 1[Tt][Ee][a-zA-Z]{23,32}

 These will match anywhere in the string so for the shorter matches on longer bitcoin addresses, you will not see 1Test at the beginning necessarily.

Ok I thought the pattern required to be after the -r flag like -o requires a file after it, thanks for the corrections for the wallet im looking forward to learning more customizable options with vanity gen

Interesting, using these I can hypothetically generate a wallet that has the pattern anywhere in the wallet by modifying these options?

That's right.  This will find the words Test and me separated by any number of characters:

Code:
vanitygen64 -k -r -o file.txt [Tt][Ee][Ss][Tt][a-zA-Z0-9]{1,29}[Mm][Ee]

We're looking forward to some hall of fame addresses from you now Wink

Haha thanks I will keep my machine running and see what I can get. I am hoping to find a lowercase wallet with the vanity pattern all uppercase. I think I know how to write the string to generate one, this along with the countless pages on the vanity gen thread helped alot.

Not a single address, but how about the "longest shared prefix"? Smiley

18eXmgR5Svoqqa6PaYVrKvbH6hvrp5xe3A
18eXmgR5Svoqqa6JXSMmbNaD4Cs5ThcV1P

(15 chars)

The hash160 shares 83bits:

53e1f4f491509f9012bd901be5147447f770018b
53e1f4f491509f9012bd825ce1e9599b253188ef

over half of the address.

The addresses are on the blockchain.  Proof of ownership:
"This address is controlled by basil00."

1MfiREDAWiEsUJhQWqkd5XySrrAkjGwtoU


 The trailing X's are pretty cool Wink
  
Addresses with only 1 number or even 0 numbers aren't very rare.  There are 4 "illegal" characters - capital o, capital I and a miniscule L and the number 0 - which leaves 49 letters to chose from and 9 numbers.  
So if we forget about the leading 1 and assume a 35 character address (they can be smaller) the probability, if matching only letters, would be [49/58]34.  

You will probably see only the leading 1 as a number in about 0.3237 percent of all Bitcoin addresses.  I just checked through a list of previously generated addresses and found 20 out of 1600 that had no numbers other than the leading 1 but those results are skewed in favour of the letters since I am looking for words.

 Now if you have all miniscule or all capital letters and few numbers, that would be hall of fame worthy!

Or an address with all (or almost all) numbers would be also very cool.
