Got my hands on a 5870 real cheap ($120 shipped). ^_^

Running at over 28 MKey/s unoptimized. Any advice on getting more keys out of my card? Using the built in Catalyst OC I get to 30 MKey/s maxing out the clocks.

Question: Why does the vanityminer only search for 1 specific address from the bounty pool? Wouldn't it be better if it were to compare the calculated address with all the ones requested in the pool?

They must be hashed independently per pool customer due to the key of the customer being part of the generated address, so only the customer can spend from the vanity address.

From a glance-through read, it would appear that one would only be able to generate addresses for a single client at a time. Am a wrong, that the hashing and checking will find an address that would work for just one client. Currently, you hash once and see if the public address has any matches from an arbitrary list.
This is a challenge...

In case anyone can not be bothered to get the old versions of the driver installed you can always use us at:
https://bitcoinvanity.appspot.com/

We just reduced prices another 20%.
And short addresses still free.

I mined addresses in the vanity pool without using the miner application (simply using a wordlist via gen). I'm assuming I'm not eligible to redeem them because I didn't use the public keys provided; Either way, if anyone wants 1PussyCum or 1Stunna1 (both were in the pool), I have keys for them. Of course, they're not generated using split-pairs, but nonetheless. :S

Why are some addresses harder to find than others when you change only 1 characters case. For example at the vanitypool there's work for a 1bitpoin, and my computer says it will find one for it in ~10 days, but when I search for 1Bitpoin it can find it in 5 minutes...?

That seems like a large variation for changing 1 digit.  Normally the max is around 50X change.  Maybe 10 days down to 5 hours?

It's due to the weirdness of the encoding system.

This is probably more detail than you want Smiley.

Your prefix gets converted into a 25 byte integer range.  The first byte is the network prefix (zero for BTC).  The next 20 are the hash of your key and the final 4 are the checksum. 

The first byte has to be zero (to give the leading one in all bitcoin addresses).  This happens automatically.

The next byte can't be zero, or your address would be 11......  Note: for prefixes of the form 11something, the calculation has to be adjusted.

So, your address must be a number with the first byte zero and 2nd byte at least 1.  This means it has to be between these 2 numbers.

(Numbers are hex and _ is just a spacer every 4 bytes/8 characters)

00_FFFFFFFF_FFFFFFFF_FFFFFFFF_FFFFFFFF_FFFFFFFF_FFFFFFFF
00_01000000_00000000_00000000_00000000_00000000_00000000

Other than that, your number depends on the actual letters used.  If you add an extra letter the allowed range drops by 58.

Another feature is that if a number gives the right prefix, if you multiply it by 58, it will give the same prefix (though the address will be longer).

"Bitpoin" has the following allowed ranges

Max: 00_759d92ad_aa9cbac1_7b8e094d_c5ae2dbe_ed97d9e9_5fffffff
Min: 00_759d92ad_a95fe99b_8977a9c8_b4d2895e_e5968fe0_bc000000

Max: 00_0207216c_ecdf6452_c8c03df4_197a2ced_390fdc08_6fffffff
Min: 00_0207216c_ecd9edf5_70b70757_5290df0e_e0a5e7ff_76000000


The bottom range multiplied by 58 gives the top range.  Both have the first byte as zero and the 2nd byte as non-zero, so they are both valid. 

If you divide by bottom one by 58, the first two bytes would be zero, so it is illegal.  Likewise, if you multiply the top one by 58, it would have the first byte as non-zero.

"bitpoin" has the following allowed range

Max: 00_06911d18_3fbe86a5_63524509_2534ef9a_74fdec84_6fffffff
Max: 00_06911d18_3fb91048_0b490e6c_5e4ba1bc_1c93f87b_76000000


If you mutiply it by 58, it goes above the top limit and if you divide by 58, it goes below the lower limit.

According to the encoding system, "b" is worth 34 and "B" is worth 10.  If you multiply the lower limit of Bitpoin by 3.4, you get bitpoin's range (since "b" is 3.4 times greater than "B").

This is the first reason that bitpoin is harder, it has only one target range. 

Another reason is if the middle of a range is a larger number, the size of the range is generally larger.  The Bitpoin top range is bigger than the bitpoin range, so again, Bitpoin is faster.

Question: Is there a way of making a deterministic vanity wallet?

Answer: I believe there is a way of supplying a randomly generated root / chain / whatever key, then a specific deterministic method of address generation, and outputting a sequence of vanity addresses that is the same each time. However, the sequence will take as much time as needed for every single vanity key.

Example: 100 vanity bitcoin addresses all beginning with 1dice, 1Dabs, 1whatever will take on average 100 times it takes to generate a single one.

More food for thought: This might be extended to make vanity public addresses (watch only) without knowing the private keys. Some wallets can already do this on non-vanity addresses using a master root / chain key (that knows the private keys) and a public root / chain key that knows the equivalent public bitcoin addresses only.

Request: Use compressed keys by default for all future projects.

Sorry for not wanting to search through 60+ pages of text for a answer someone could click three times to quote the answer to my problem. My bad, how selfish of me.

I'm quite interested - is this basicaly bruteforcing? Also, what happens to all the adresses that are generated? Are they just going to a waste forever or do they "recycled", also, how many addresses can be brought into total existance? I generate a LOT of keys per second and I'm curious, am I wasting a lot of addresses?

As far as I understand it, all addresses 'already exist', so to speak.  It's just a matter of having a private key.  If you 'generate' a key, youre not magically making it appear, youre just doing the math that gives a private key that happens to correlate to whatever its address is.  Same way you could just smash in some keys (within constraints that would make a valid address) and send coin off to the nethers of a random address, lost unless someone happened to come upon a private key for that address.  'Generating' a vanity address is really just spam checking random address/private key combos until you happen to find an address you deem interesting.

The search box at the top of the forum will search only the thread or board you are currently viewing. The key is to type in creative search terms, a phrase that revealed the answer for me quickly is "lower case".

Nine character non-caps patterns arn't so hard to find. Now try and find a 13+ character "1" pattern short address.

hi everyone,
does oclvanitygen support multiple gpus ? or do i need one instance per gpu?
i have a 6x 7950 rig that i want to test.

you have to run multiple instances.
do you use win or linux ?
you have to use 12.10 drivers (on both).
and disable BFI_INT in source code for 7xxx cards.

No, just do -D 0:0 -D 0:1 -D 0:2... and so on...  and you an run multiple gpu's in one instance for example:



Works for me great on my 660ti's

Dunno about AMD.
