I want firstbits key pair for 1gig

[CIYAM]

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).

of course, it may also be possible to generate a new 1gig address and ask firstbits to change 1gig to your one, making the case that you would actually use it.

what you think about is something like btc.to

I cannot imagine it would be hard to add the ability to do as I said, and if I was running the site I would do it, But then, I would have had it from the start, to deal with copyright claims and the such which will come as bitcoins grow in popularity, if 1coke is already gone do you think coke would just allow me to list 1coke as an address that isn't theirs? not to mention if there was a demand I could monetise the registration of firstbits on top of the "ruleset"
And for something like 1gig that is useful to the OP but being taken up by an unused and possibly lost address... Its just silly to say "THEMS THE RULES"
I also never said blockchain.info queries firstbits, no idea what you are smoking with that one

of course, it may also be possible to generate a new 1gig address and ask firstbits to change 1gig to your one, making the case that you would actually use it.

Would you rely on firstbits if someone could change it?  Vanity addresses are a bad idea but firstbits only works if the addresses are deterministic.  1gig will always be the first address beginning with 1gig that had a tx in the blockchain.

If it is stuck on an unused account and changed to a used one, sure its fine to change them, in the case mentioned above where it could be monetised, "unregistered" firstbits would be listed as such, and subject to change should someone register it
"Vanity addresses are a bad idea"? and firstbits only work if the addresses are deterministic? what? ... please explain.

OK, I agree, now it is silly.  

But what ever happened to the addresses that start with 3? Did that BIP ever pass?  Is it deployed yet?  What is the schedule?

Who owns 1GiGKdNCywjPxdXEg6PbPtXWYNZStFoSfr?

I am interested in this address and the keypair that goes along with it.

Who owns this address?

If I had the key and gave it to you, you would have to trust me to destroy it and not use it to steal your funds at some point in the future.

speaking of firstbits, someone reserved a shit ton of them with some common words back a year ago

just found it by querying some of mine vangen addies. gotta move few satoshies to few that didn't show up yet.

[rjk]

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

Who determines "stuck in an unused address"?  Say I have FirstBits address 1Crypto. I go to jail for 20 years but during those 20 years people keep sending funds to 1Crypto.  When I get out I learn that oops 19.9 years ago someone got 1Crypto changed to a different address.

Now lets make it more complicated.  Right now the way firstbit works is every client, website, user who uses firstbits SCANS the blockchain to find the first usage of an address matching the prefix.   There is no communication required to a central authority or a list of unregistered addresses.  

Say genuinely 1gig could be reassigned.  How do you notify every user on the planet using a variety of websites, exchanges, clients that 1gig not points to a different address?  What if some of those users are running clients which aren't updated?  They keep sending funds to the wrong address?

"Vanity addresses are a bad idea"?

They break the psuedo-anonymity of the bitcoin address scheme.

and firstbits only work if the addresses are deterministic? what? ... please explain.

deterministic as in from now until the end of time the "firstbit" of every single bitcoin address can be determined with nothing but an algorithm and the blockchain.  If addresses could be reserved, or assigned, or reassigned that wouldn't be possible.

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)

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,

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.

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

I think my best one is 1e111.

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.

Incorrect.  Had a brain fart this morning.

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

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.

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.

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.

[SgtSpike]

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.
