just in case someone misunderstands your post: in Russia, passport for international travel is called "foreign" passport to disambiguate it from the internal ID, which is also called "passport".

There was a law recently passed in Russia that criminalizes development, production and distribution of skimming devices. So the Russian guy selling those is probably trying to make it less likely that authorities will go after him.

Doesn't seem obvious to me at all. As a result of bankruptcy proceedings we know that Mtgox has lost primarily BTC deposits, not fiat (on mobile now, but IIRC only $27 million USD was lost which is peanuts compared to the value of

It's definitely not a problem right now. With the current block size limit (and blocks are currently filled less than 50%), it will take at least 20 years to surpass 1 terabyte. Bitcoin has to become much, much more successful (think h

Huh? 1tb hdd was released in 2007, 2tb in 2009 and 4tb in 2011. Looks exactly like Moore's law to me though we've been set back by Thai floods of 2011.

In order to make a successful attack against a merchant accepting zero-confirmation transactions, the attacker has to: 1. Submit transaction A to miners 2. Submit another transaction B (spending the same coins as A) to the vulnerable mercha

Average time between blocks is 10 minutes. Your transaction will be in the middle between two blocks which results in a 5 minute average wait.

Let's say you accept bitcoin but immediately convert it to USD. In future one of your suppliers also decides to accept bitcoin. Now you can pay your supplier directly without the USD conversion step. This wouldn't have happened wi

The parent comment said direct transfer. Bank wire involves intermediate parties, is subject to various capital limits, account closures, funds freeze etc.

To see how absurd this logic is, start with buying bitcoins first: 1. Buy 1% of bitcoins 2. Price increases 3. Sell your bitcoins for more than you bought them 4. Goto 1

If you accept a 0-confirmation transaction and listen the network for a few seconds to ensure no double-spending transactions are broadcast, this is a reasonably secure way to accept those small transactions where 10-minute delay between bl

In theory, each coin (called transaction output in bitcoin lingo) can be traced through a chain of transactions to its originating block. In practice, this is useless because there is no correspondence between bitcoin addresses and individu

I think this is just as unlikely as the idea that Facebook is a law enforcement honeypot to track terrorists' social graphs. Your arguments sound somewhat plausible now, but back in 2009 bitcoin was just a cypherpunk's toy and no

It's absolutely huge. If 2/7 of the world population owned bitcoins, there would be at most 0.01 BTC per person.

Why lunacy? You need a huge amount of computing power to make a distributed currency resilient against attacks by the likes of NSA, hostile foreign states, etc. And to answer your question, no, the chips cannot be repurposed for anything el

Some nitpicking: the passphrase is not as good as it seems. It consists of two parts ("horse in a box" and "riding a fish") both of which can be found in e.g. Google's n-gram corpus [1]. The Google's corpus has

My first thought when reading the article was to prohibit RIAA and MPAA from visiting torrent trackers etc. You can even preemptively send them a C&D letter in pretty legalese.

I agree with Steko that being case insensitive is not a big deal. If you force users to use randomly generated passwords, 12+ characters is safe whether case sensitive or not. On the other hand, if users choose their passwords themselves...

They didn't use an Android exploit specifically, they simply scanned the blockchain for vulnerable private keys. They probably didn't even know that Android was the culprit - it could be hardware wallet, a buggy homebrew client or

This is exactly what the standard bitcoin client does - it creates 100 addresses when installed.
