will pay 2 BTC for 1 BTC with traces of that pizza on it

[SomeoneWeird]

I finally managed to figure it out!

Here is a 75-long chain of transactions all the way from the pizza exchange to the coins I got for the "cryptographic keys" T-shirt at Square2Wear (which I still have). Obviously there's a lot of mixing due to multiple inputs, so it isn't strictly speaking "pure", but I hope that is forgivable. Are you ready?

how on EARTH did you manage todo that...

Oh ok, sweet, care to share?

Oh ok, sweet, care to share?

Ok, copy all the files into the bitcointools folder:

This one is a small modification to a bunch of functions found in bitcointools that makes my life easier: http://dl.dropbox.com/u/28441300/deserialize_unfinishe.py

Here is the first program that I used to find out whether any of my unredeemed coins were actually descended from the pizza transaction: http://dl.dropbox.com/u/28441300/bitcoin_descendants.py

Next, seeing that I had some at one of my addresses, I made another program to find the exact path:
http://dl.dropbox.com/u/28441300/bitcoin_descendants_pizza.py

It's kind of sloppy (I wasn't planning on releasing it), so you'll have to change a few things to use it for a more general case (parent_block, parent_transaction, my address, the restriction for only transactions with 1 BTC or more).

* ptmhd back from holiday

catching up with the bitcoin latest events
thanks for the amazing work on block explorer

and i'd be happy with diluted pizza bitcoins
so any coins linkable are fine for my anchovy pub key project

[unfinishe]

Ok, just tell me what address to send it to.

[Binford 6100]

Ok, just tell me what address to send it to.

wow, you really got one?
i'll create a new address for this one transaction to make sure it can be dumped from wallet safely
and stored in my coin collection display
i'm using bitcoin only from home, please allow few more hours for reply

yay!

[unfinishe]

Just to be clear, whenever you're ready, I will send 1 BTC (or however much you want... the prices have been pretty crazy lately) from my account with the T-shirt coins (the ones at the end of that huge chain I posted earlier in the thread), to another one of my addresses (just so I can make sure that the chain looks good), and then I'll send from that address to yours. So, all you'll need to do is add two more transactions to make a grand total of 77 transactions from the legendary pizza to you.

[Binford 6100]

whenever you're ready

ready I am, offer to exchange 1 : 2 still valid is

was offline yesterday after leaving the office, no new wallet created
the long chain from pizza to me does not disturb me
those coins might not be XF or uncirculated but still very important for me
i might be the first bitnumismatic eva ; )
thanks for the bump, please do not spend them all. i'm setting up a reminder for today

edit: if i wanted moar, let's say 50, would you ask for 51 or for 100?
i was lucky with zimbabwe dollar exchange so i have a few bitcoins i can put aside and never use

[unfinishe]

Well, I only have 3.5 to give, but if you wanted it, I suppose I'd be willing to trade for 4.5.

[Binford 6100]

i wanted to post the adress here but then i might receive unrelated bitcoins if some funny guy would like to spoil the wallet with tasteless coins. pm sent and please reply where i should send you mine. once again thank you very much, a dream comming true

[Binford 6100]

solved, issue closed. was great fun and now I have a piece of the legend
thank you all for contribution especially to unfinishe for a nice exchange

btw if you stumble over the coins from satoshi to hal from tx in block 170
please leavme me a message, i might be interested as well

[error]

I look at block 170 all the time while I'm writing code to parse the block chain. If I come up with anything I'll let you know.

[k]

so, I'm guessing block 170 http://blockexplorer.com/b/170 is the first transfer from one address to another?

had a look at some of the previous blocks (but not all 170) and didn't see any transactions.

Is this going to turn into the bitcoin equivalent of Six Degrees of Kevin Bacon?

Yes, block 170 contains the first Bitcoin transaction (other than generation, of course).

[Binford 6100]

true. mined coins must mature at least 100 blocks or so, to be spendable. it was not possible to send any coins in the first 100 blocks

I look at block 170 all the time while I'm writing code to parse the block chain. If I come up with anything I'll let you know.

hal actually is active on the forum, i just might ask him directly. but if you stumble upon the coins, i welcome any info

seven degrees of bacon pizza?

[Binford 6100]

seven degrees of bacon pizza?

more like ordinary passion for coins. I doubt that people check their coins history and see if they are connected to pizza or first transaction
