My giantest transaction so far... at least in terms of number of outputs in a single transaction.

Thought it would qualify as something interesting to look at.

It is the loading of a stash of almost 2000 BTC worth of physical bitcoins in a single transaction.  Call me OCD, but I like making my transactions look interesting in block explorer as well.

EDIT: Just topped it: 1,042 outputs in this one.

Isn't this a security risk or something to openly say all of these adresses are coins?

I am trying to understand the structure of transactions at the moment, and it would be useful for me to see a hexdump of transactions for comparison to block explorer.  Is there an easy way to generate that?

The list of addresses is already published.

Even if not, this sort of transaction is unique enough that it could easily be scanned for in the block chain.  Finding BitBills is just as easy.

I find it particularly impressive that Bitcoin can move 1900 BTC to 312 addresses in only 10.8 kB.

does that represent one sale?

I think in the future a statement like this might be remembered fondly just as the 10,000 btc pizza.  =)

Is this why the price just dropped by 0.5 ?

No, someone dumped like 40k coins... way beyond the 2k Casascius mentioned.

ah, thanks!

where can we check this?

Nice!  I will be ordering more very soon. 

I know you hate making the damn little things, but I have a stack of them on my desk and I want more!

And in this case, I didn't dump the coins on the market, I pretty much removed the coins from the network - completely inaccessible until someone hand-types the private keys back into a computer.

That would have an upward pressure on the price, not downward, if anything.

Exactly.  Not sure people got the idea that doing an internal transaction (from address Cascius controls to addresses on Cascius' coins) would cause a drop in exchange prices.

Arent you taking a hit with the recent price drops tho?

Nice. I wonder if the coins I ordered a couple days ago are among them. :)

Interesting! I wonder who did that and why.

If someone sold 40,000 Bitcoins on Mt. Gox right now, he would make $78,350, getting an average price of $1.96 per Bitcoin. I wonder how much the fella selling his 40,000 BTC got per Bitcoin...

Can anyone track down the block that contains the deposit related to this sell? I assume we would be able to see the deposit to a Mt. Gox account in the block chain. Of course we can't know if it was a gradual deposit or a single 40,000 BTC one, or when it happened.

Do any tools exist that can be used for working with the block chain locally? Can I, for example, somehow do a search in the block chain for a block containing at least, for example, 40,000 BTC worth of transaction within the last 7 days? That would be really interesting to be able to do.

You can try...but it might be hard. You can import private keys to mtgox now, as well as use codes to transfer between accounts. You have no idea how long someone had funds in mtgox or if they got them from buying on mtgox in the first place.


yes, try here: https://bitcointalk.org/index.php?topic=50721.0

I see. I guess that can be seen as good - the available anonymity. I pulled some historical data from bitcoincharts.com to see what was going on, and have written a bit about it here if anyone is interested: https://bitcointalk.org/index.php?topic=51774.msg619470#msg619470 (https://bitcointalk.org/index.php?topic=51774.msg619470#msg619470)

Thanks a lot for the link to subvertx! Looks very useful. But I guess you are right in implying that large trades on the exchanges can't be - and maybe shouldn't be - effectively traceable in the block chain.

Just topped it: 1,042 outputs, 35.6 kB in this one.

Very nifty. I can take a good guess as to which output is your change, though. :)

The fact that none of the coins have been redeemed makes that kinda easy. :)

Hey Mike, some of those outputs have been redeemed, does that necessarily mean that someone ripped the hologram off and transfered the contents?

example: http://blockexplorer.com/address/17MdPjZN1HfmVStJhi8AKF8KAyQ2jzunrt

Exactly.

Seems to be the case with many of the 100 BTC bars. Have you compiled any statistics on the number of pristine/defiled coins or average deflowering time?

A couple of others have.

http://casascius.appspot.com <--- more accurate at the moment

Seems the bars get ripped open pretty quickly, presumably because the buyers just want the BTC (they are buying from MemoryDealers for USD, not from me)

Perhaps there's a market for higher denominations on the cheapest possible material. I am interested* in a graphs over time...

* not so interested to do it myself. :(

It does seem that if delivery of a physical product mitigates the risk of accepting Paypal/Credit Cards enough for companies to do it, that just mailing out private keys on paper ought to be sufficient for people who are just trying to buy bitcoins to have electronically. It seems the same thing to me, of course, but perhaps the fact of whether or not there's a real "coin" involved actually does make the payment companies look at it differently somehow.
