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

http://blockexplorer.com/tx/2e1400626bf6076177ed221ca3f75eb3289a80d8952d54c122206e3114e96aed#i3271326

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.

Companies claiming they got hacked and lost your coins sounds like fraud so perfect it could be called fashionable.  I never believe them.  If I ever experience the misfortune of a real intrusion, I declare I have been honest about the way I have managed the keys in Casascius Coins.  I maintain no ability to recover or reproduce the keys, not even under limitless duress or total intrusion.  Remember that trusting strangers with your coins without any recourse is, as a matter of principle, not a best practice.  Don't keep coins online. Use paper wallets instead.

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.

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.

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.

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.

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

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.
