Prefix '3GiG' not possible
Hint: valid bitcoin addresses begin with "1"

Vanitygen doesn't support 3 addresses AFAIK, because they use a different type of hashing. You're going to have to write your own program to do it.

I have said it before and I will say it again!

KAKA!

Nothing personal, but I don't trust firstbits any more than online wallets. Vanitygen is cool, but vanity really isn't my thing.

I don't think anyone should trust it any more than an online wallet, unless they calculate the firstbits themselves.

Hmmm... that might be a decent standalone app. Given a block001.dat, calculate the firstbits of a given address.

And a block002.dat, don't forget.

Good to know I am not the only one going nuts!

Shit storm? You call this thread a shit storm? Have you ever visited other part of this forum? Lending for example? This thread is a rational breath of fresh air!!!

Not sure why. I think all of your questions have been answered. What exactly do you want to know?

To add to what FreeMoney said, the firstbits of an address will never change, and the address related to a particular firstbits will never change. The only exception to this would be if there was a major reorg of the blockchain (rewriting at least 7 prior blocks), but I think we would have more serious issues with Bitcoin to deal with if something like that were to happen.

Would 3gig be good enough for you? Just curious.

there are addresses that start with 3?

It has been a while since I looked into it but a while back that was the designation for a script based address. If still true then eventually there will be addresses that start with 3. Others that keep up on these things more than I can answer the question.

There are 3-prefixed addresses in common use. For example, this one. 3gig is not yet taken.

that's ridiculous. e.g. sites like blockchain.info don't query this "firstbit database". there is a set of rules which determine the firstbit address and that's it.

I don't think that this is correct as I have created vanity addresses whose "firstbits" don't show up on blockchain.info until sometimes as many as 10 confirmations (which is when they seem to first appear on firstbits.com).

The only way a firstbits address can changeis a blockchain reorganization. Firstbits.com waits for confirmations because we don't want to tell you your firstbits until it's very solid, like Gox doesn't want to credit your account until so many confirmations, they have the coins, and your address has it's firstbits, we're just not telling you yet.

To be super clear. Firstbits.com or any other correct implementation (like blockchain.info) does not decide your firstbits, we just report what the algorithm comes up with after looking in the chain.

Yep, my 1Freenode address covers a few other prefixes that weren't there when I generated it.

How long did that one take you to find?

Less than a day on a 3x5870 rig, I actually found 2 of them.

Personally I'd go for 1gigabit. It's not in the chain yet and has a 50% chance of being found within 9 days on my mining rig. So that would cost me 3.69 BTC. Nah, not going to bother.

It would require also finding and funding an address for 1gigabi first. If you found a 1gigabitxxxxxxx address and funded it then it would be assigned the firstbit of 1gigabi. Since finding a 1gigabi is less computationally intensive one could find an address with that prefix and send it a satoshi to act as a placeholder. Luckily 1giga, 1gigab already exist otherwise they also would need to be found.

If you put money on 1gigabit..... then you would automatically also have 1gigabi since it would be the first occurance of all these partials. You can always use more characters in your firstbit than needed as long as they match your real address.

D&T is right. There is no database for firstbits.
It is simply the first address found in the blockchain that fully matches the firstbit prefix (non case sensitive). An address is reserved by sending coin to it so that it gets included in a block.

I remember when FreeMoney first came up with the idea and made the site. It was right around the time I first heard of bitcoin. First described here,

Silly would be... 1gigg1e - 50% chance in 6 hours and not currently in use.

I think my best one is 1e111.

Sooo.. with all the spam from people reserving "first"bits, how about creating a service for "second"bits? Grin

I know you are joking but I think other people do have this misconception that you "reserve" a first bit address. You don't. Every new address added to the blockchain can have their first bit address calculated based on a set of rules.

Simplistically to find the firstbit (F) for any address (A):
1) scan the blockchain for A. If A is not in the blockchain or doesn't have 6 confirmations on its first tx then it has no firstbit. F = null
2) Find the first tx of A and record the block number (b) that it occurs in.
3) Create the smallest potential firstbit pattern (f) for A. f = 4 leftmost digits of A.
4) Scan the blockchain (from block 0 to block b) for any address which matches the pattern f.
5) If a match if found then add one digit to f and goto step 4
6) If no match is found then F(A)=f (the pattern f is the firstbit for address A)
