Bitcoin Forum

Tomorrow will be 1 year from laszlo's post that he was able to exchange pizzas for bitcoins.
I want to have at least 1 bitcoin from that pizza storry.

So please, if you can trace your coins back to this transaction and read this post (and want to double your bitcoin),
PM me and we have a deal.

This idea is amazing. But I think it's not really feasible, they have probably been thoroughly mixed with the rest of their little buddies :)

amazing, it seems a bitcoin is a bitcoin is not true. some are more valuable than others.

saw something in another thread about how newly mined "pure" bitcoins with no transaction history can have a premium over other bitcoins due to their potential non-traceability.

Now someone valuing certain bitcoins more than others due to their transaction history.

how about the bitcoin with the most number of confirmations? i.e. one that was mined or spent a long time ago and then just kept since then?

i believe it's doable. all transactions are linked, don't mind if i'll be 1000 transactions from that pizza, just want to have link to that transaction. that key would be dumped, removed from wallet and never spent. so much i love it. and pizza. and pipes. and moon. and zeppelins and light bulbs. i'll go and question blockxplorer to see how the bitcoins moved since then and estimate my chances to get my hands on them.

btw since bitcoins are divisible, i would pay 2 btc even for a 0.01 part of it. you know, collectible ...

go tell numismats all over the world they're all morons :)

in block 170 first transaction was recorded. satoshi -> hal.
keeping in mind that newly found coins need to mature 100 blocks to be spendable, they started to test the protocol pretty early. but that transaction does not interest me. i would maybe donate few cents to see a graph how that coins were spent but not really interested in owning them

well i mean that the 10k tx out might have been used as an in for other txes along with other ones.
Let's say the payee then spent 20k coins using two 10k ins and creating a single 20k out, then those 20k have half the original pizza smell

didn't mean to suggest that anyone was a moron. not at all. just the concept of bitcoin numismatics is amazing and fascinating.

hm, bitcoin meets homeopathy. i see the point now. but that makes looking for a bitcoin with anchovy even easier.
let's hope the buyer does not sit on the coins and they are available.

btw i can't search the blockexplorer by block number or date :( any workaround for that?

Yea I understand, that's also pretty much why I'm still mining solo, I want the delicious smell of a freshly printed pure money to appear in my house :D

The obvious person to ask is jercos, who received the payment from laszlo. I can't recall seeing him on the forum, but he has been on IRC. Even if he has been spending that money, he's highly likely to have some change transactions from it.

Thanks, i'm waiting for him there. Seems like biggest part of the problem solved. Thanks!

I currently have about 0.5 btc in my wallet.

If there's an easy way to trace them back let me know.

If you want to do the tracing, some of the links below have my address in them.

I'll sell all my pizza linked cents except one I'll hangon to.

I guess I could move them all to one address so its easy to locate all that's mine.

And you know they're all pizza linked, how?

I dont know, guess i should edit the post to make it more clear that if they wete linked id sell them, and i dont know a good way to determin if they are.  Theres a possiblity they are linked, as long as  papa johns spent them.

I successfully located the original pizza transaction in block 57043 (http://blockexplorer.com/block/00000000152340ca42227603908689183edc47355204e7aca59383b0aaac1fd8).

This is no more than a coin collector looking for a coin with a certain serial number or print.

I spent a couple minutes looking at transactions and was able to find 100 BTC at an address that came from the pizza transaction.

Original pizza transaction (http://blockexplorer.com/tx/a1075db55d416d3ca199f55b6084e2115b9345e16c5cf302fc80e9d5fbf5d48d#o0)

which were sent to two different addresses (http://blockexplorer.com/tx/cca7507897abc89628f450e8b1e0c6fca4ec3f7b34cccf55f3f531c659ff4d79#o0)

Tracking the larger transaction (http://blockexplorer.com/tx/3b8328fe7e53a8162cf023738a53c85a3cbf21efe517ab878e8cfecc3a2e22db#o0)

In this transaction the 5777 BTC and the 4333 BTC were joined back together along with many others (http://blockexplorer.com/tx/9e744590d196b63d02a1dd7ef596fd6082286f84295d66da411a9ffebfdd1957#o0)

Which was then split (http://blockexplorer.com/tx/1d001840a1eccd2d3f0505a6b54d60812cf9295a08a1afc48871cf21ad1147f8#o0)

and split again (http://blockexplorer.com/tx/6ac97d586d1bbcc71d5d735bacd4535a7bbfb5cb074eb7b562d7a49c258a61fa#o0)

and again (http://blockexplorer.com/tx/967e8c36a633d2451525f4a833c2fa7574f8f56932bc3d6e939c5a624cebf60d#o1)

and again (http://blockexplorer.com/tx/fae1d55a6d983536a2a34515d2dcc67f92e4535f645a82eded11e6ee3c19399e#o1)

and again (first block in 2011) (http://blockexplorer.com/tx/54d5f507d301a392f400c21b36eeba7f40446a45654de52f30cb291321d5d5e1#o0)

and again (http://blockexplorer.com/tx/12dd01067e7536cb8df01cf2faa28fcc11421893b15d0958b0e002eacdbdc78a#o1)

and again (http://blockexplorer.com/tx/5747cfe8c8e795d0e0e62dd2c058aab381ec3cbbcfd4ea6d7a4986eac12c9e7e#o1)

and again (http://blockexplorer.com/tx/d70e199e6195485f433944bc4833a061231d678a8182eb54f2bd73efec7a0b47#o1)

leaving us with 100 BTC yet to be redeemed from this transaction (http://blockexplorer.com/tx/f06aa5ddad1aca5c53eded0c2debe4961036a99b6f738364e3f9b19a6ccf9297#o0)


And since the 10000 pizza coins were included in a transaction with 11022 coins I guess you could say these 100 coins are 10000/11022 = 90.7276% "pure"  :D

Now to find this wallet! I'm sure there's many other BTC that can be traced back too someone just needs to put in the work I suppose.

this can make an interesting example of how bitcoin transfers may not be 100% anonymous all of the time. 

I finally managed to figure it out! ;D

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?

Phew!

how on EARTH did you manage todo that...

I sure as hell didn't do it by hand. :D

I did it by making a python script, largely based on bitcointools (http://github.com/gavinandresen/bitcointools)

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).

Appropriate address... ;D

/me 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

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!

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. ;D

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

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

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 :)

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

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.

so, I'm guessing block 170 http://blockexplorer.com/b/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).

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

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?

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

This is why we need clients to have address differentiation.
As it is, the client gives no option for spending specific coins, so if 1BTC is from pizza history and 199 are from other history, it will be difficult to pick the correct one.
Of course merging all 200 to one address could work, but then it gets watered down. . .

Client should give option of which received address BTC to send. . .

you have a handful of options
- new wallet for new incomming coin to your collection
- wallet for the whole collection but you shall not spend from it & new address for new payment is a must
- keep accepting them as usual, spend them when the time will come

if you're skilled enough (and a collector), you can remove the private key of the address with the valuable coin
and -rescan to update the balance of your account. this is actually the bitcoin, the key to it is everything.
this way you should be safe not to spend it by chance (the client would not have the signing authority over the bitcoins)
