My totally non-repeatable grep|sed|uniq -c script couldn't find conflicts even with these four char vanity prefixes. The fact that all of these four char vanities all begin with capitals makes me suspect their creators had no firstbit aspirations. I would think it's early enough in the game that there's no pr... famous last words. I'm curious what you come up with.

Code:

Duplic's Block:Prefix

"String required to differentiate an address from all addresses in the SAME and previous blocks"

+1 from the peanut gallery. I had been searching for exactly such a case (I have seen some strange vanity addresses in the same block which might qualify). Are you aware of any real world cases on this ambiguity?

Writing something that will find any/all.

I definitely prefer the same or previous rule, but is it worth changing if it changes many FB?

I assume you are calculating them independently?

yes, they should be fully compatible with firstbits.com though.

Very cool, glad to have a separate implementation.

One little possible wrinkle though. We have been ordering two transactions that would otherwise have the same firstbits if they were not in the same block according to their appearance in the block data (first to appear being first). We are investigating switching to giving them both the longer firstbits. An example:

Block 1:
1asd1234567...

Block 2:
1asd2fkkkgrt...
1asd2sqp434...

Currently 1asd2fkkkgrt... would have FB of 1asd2 and 1asd2sqp434... would have FB of 1asd2s.

It seems like it might be better to not need the extra rule of tiebreaking with order of appearance and instead to give each the FB as if the similar address came before. In this case giving 1asd2fkkkgrt... a FB of 1asd2f. It seems more elegant to use a rule of "String required to differentiate an address from all addresses in the SAME and previous blocks" and have nothing about order in the block.

Very sorry for not addressing this before or publishing our exact code. Would like your input on this issue.

Right now I'm drunk as hell. FirstBits helped me transfer 10 BTC between my computers. An admirable service, in my opinion.

Wonderful. Very glad it's helpful and easy enough for a drunk to use. :-)

It took a few tries >_>

(3 seconds later) OH GOD WHY AM I MISSING 10 BTC?!?! hehe

Well why use a website. Wouldnt it be best to code this into the client?

Do I hear a bounty? Seriously! Has this been proposed to the dev team? are they open to the idea?

(I might make a stab at the node.js project, but I can't make heads or tails of Satoshi's code).

First bits really ought to be the standard in the clients. It *might* even compress the local blockchain. The address is only a hash of the key. We don't really need the 32-char address except as.. well.. an address.

You have to be always drunk. That's all there is to it—it's the only way. So as not to feel the horrible burden of time that breaks your back and bends you to the earth, you have to be continually drunk.

But on what? Wine, poetry or virtue, as you wish. But be drunk.

And if sometimes, on the steps of a palace or the green grass of a ditch, in the mournful solitude of your room, you wake again, drunkenness already diminishing or gone, ask the wind, the wave, the star, the bird, the clock, everything that is flying, everything that is groaning, everything that is rolling, everything that is singing, everything that is speaking. . .ask what time it is and wind, wave, star, bird, clock will answer you: "It is time to be drunk! So as not to be the martyred slaves of time, be drunk, be continually drunk! On wine, on poetry or on virtue as you wish."

Hello Firstbits aficionados.

I have posted an idea that combines Firstbits with people's names on the "Development and Technical Discussions" forum.
(I probably should have put it here but did not think of that until too late).
The topic is:

https://bitcointalksearch.org/topic/firstnames-combining-peoples-names-with-firstbits-for-short-bitcoin-addresses-38664

The subject line for the idea is:
" Firstnames | Combining people's names with Firstbits for short bitcoin addresses"

I really, really am not trying to hijack this thread but would be very interested in your feedback on this idea. If you could post any comments on that thread all the comments will be in one place.

I am hoping if you like Firstbits you will also like the related idea of "Firstnames".

Thanks in advance.

Bug report: for some reason, copying and pasting an address gave weird results in this machine, so I partially copied it, then pasted it and manually typed the remaining characters. I unavoidably

mistyped the last one, and entered "y" instead of "Y". I didn't get the message "This address isn't in the chain", but I got "Your firstbits address is:" instead, without any firstbits address after that message.

Bug is fixed, thanks for reporting!

To be clear, I am in favor of other people making other systems, just not calling them firstbits. Anything calling itself firstbits should use our exact algorithm and opening the code will help people do that.

thank you freemoney for keeping with the basic algorithm. i know a lot of people here are all about "marketsmarketsmarkets", but this really is a technical matter, not an economic one.

i also, personally, think that if firstbits.com integrated this, it would dig its own grave. not that you make any money out of it, afaik.
