I hate you and hope you die

You have just modified the javascript in your own browser. The javascript is the bitcoin client and if you modify the client then of course you can change it to print the password or private keys etc. It would be trivial to modify the Bitcoin-Qt source to add an alert box which prints the password in a similar fashion.

This is how the service works, client side.

For a single coin, casascius.com charges BTC 1.50 and prohibitively high shipping cost to anywhere outside of the US.

Offers like this one fill that niche.

For example:

1 coin shipped to germany from casascius official page will cost you BTC 1.9 (incl. shipping) and take about 10-15 days.
1 coin shipped to germany from me will (using currently highest bid) cost you BTC 1.418 (incl. shipping) and take about 2-4 days.

So it can make sense depending on circumstances.

I'm mainly doing it for fun and to spread the beautiful coins and of course bitcoin itself.

The ip address the wallet was last updated with.


With the sharedKey two factor authentication can be disabled.

Every version of a wallet is stored (every time it is updated). The users has been sent those backups, with instructions to import them into another client or a new blockchain wallet.

There isn't really any ability lock a wallet, but yes with access to the sharedKey and some custom crafted http requests he could have achieved that affect. Nethead has an email associated with the account so he will have been automatically emailed backups. With backups the extortion would be easily circumvented by importing the wallet into Multibit or any other client. This is one of the reasons why it's always a good idea to keep your own backups.

What other information could be used to identify a wallet
We store the ip address a wallet was created with and the ip address a wallet was last updated with.

A wallet can be looked up by SMS number or email if that information has been added in [Account Settings].

Nikolaos,

I looked up your address with Blockchain, and %100 for sure the funds were sent to a Bitcoin address that you control.

Here is the proof of the link to your account corresponding with Bitcoin address: 1H4UR5M72Ybpo4zrqWe8JKKYSeN1gxqBcU

500k/block would be necessary if 300,000,000 people used it.  That would keep the currency at roughly parity with the dollar (which makes sense, in order to avoid the psychological "less is not more" barrier).

It is also necessary to continue with block rewards, so that the currency doesn't go into a deflationary spiral (which WOULD happen - see "The Great Depression").

I also believe that, with the current Bitcoin client, transaction fees will not be high enough to maintain a sufficient number of miners to keep the network secure.  Once we hit 25 BTC rewards, the number of miners will drop in half.  Same thing when we reach 12.5 BTC rewards, etc.  The end result is that we wouldn't have enough money being spent on mining to keep the network secure, which I'll explain in further detail.

If we assume there is no growth in bitcoins from now until the reward is effectively gone (and thus no value increase), then miners will see a reward of 0.05 BTC/block or so.  Which means that the network would be secured, theoretically, by 1/1,000 of the number of miners that currently secure it.  We'd have 20-50 GPU's securing the entire network worth $210M.  In order to maintain the same level of network security that we have today, on a "hash-per-market-cap" basis, we'd have to have 1000 times the number of transactions in each block that are currently had.  That's just not going to happen unless worldwide adoption becomes a reality, so we will always have a discrepancy between the hashing power securing the network and the total value of the network.  Sure, if prices reach $1,000, then we might have 2,000 to 5,000 GPU's securing the network, but that network would be worth $21B.  So 2,000 to 5,000 GPU's probably isn't going to be enough at that point either.  At the current transaction rate, the network will not be sustainable in the future.

See the problem?

It's not inflationary - it's stable.  Well, eventually anyway.

Once the number of coins generated equals, roughly, the number of coins accidentally lost, then the currency is stable.  It shouldn't increase or decrease in value.  Up to that point, it would be inflationary, but the hope would be that the adoption rate of the currency would keep up.

Why was he banned?

Hey guys, just short a bitcoin from a purchase I'd like get on Silkroad.

I can repay 3 BTC about a month after my purchase [Around Jan 19, 20, 21]

PM me for information.

Thanks.

So what are the next steps?  How is this all going to get settled?
