Yes, the writing styles of Szabo and Satoshi are the same. Apart from the British spelling. And the different punctuation habits. And the use of British expressions like mobile phone and flat and bloody. And Szabo’s much longer sentences. And the fact that Szabo doesn’t make the same spelling mistakes that Satoshi does. Ooh and the fact that Szabo’s writing has a lot more humour to it than Satoshi’s.

Szabo has extensively studied British history for his legal and monetary theories (it's hard to miss this if you've read his essays), so I do not regard the Britishisms as a point against Szabo. It's perfectly easy to pick up Britishisms if you watch BBC programs or read The Economist or Financial Times (I do all three and as it happens, I use 'bloody' all the time in colloquial speech - a check of my IRC logs shows me using it 72 times, and at least once in my more formal writings on gwern.net, and 'mobile phone' pops up 3 or 4 times in my chat logs; yet I have spent perhaps 3 days in the UK in my life). And Satoshi is a very narrow, special-purpose pseudonymic identity which has one and only one purpose: to promote and work on Bitcoin - Bitcoin is not a very humorous subject, nor does it really lend itself to long essays (or long sentences). And I'm not sure how you could make any confident claims about spelling mistakes without having done any stylometrics, given that both Szabo and Satoshi write well and you would expect spelling mistakes to be rare by definition.

so I'll forward them to you to post on your website.

Thanks.

I didn't mean that he doesn't know C++. Given that he was a computer science major, he almost certainly does know C++ or can easily learn it. What I meant is that he is not known to have programmed much in C or C++, or known to have done any kind of programming that might have kept one's programming skills sharp enough to have implemented Bitcoin (and to do it securely to boot). If he was Satoshi I would have expected to see some evidence of his past programming efforts.

I see. Unfortunately, this damages my defense: I can no longer say there's no evidence Szabo doesn't even know C/C++, but I have to confirm that he does. Your point about sharpness is well-taken, but the argument from silence here is very weak since Szabo hasn't posted any code ever aside from a JavaScript library, so we have no idea whether he has been keeping up with his C or not.

why would Satoshi say "expands on your ideas into a complete working system" to me, and cite b-money but not Bit Gold in his paper, if Satoshi was Nick?

Good question. I wonder if anyone ever asked Satoshi about what he thought of Bit Gold?

An additional reason that I haven't mentioned previously is that Satoshi's writings just don't read like Nick's to me.

I've seen people say the opposite! This is why I put little stock in people claiming Satoshi and $FAVORITE_CANDIDATE sound alike (especially given they're probably in the throes of confirmation bias and would read in the similarity if at all possible). Hopefully someone competent at stylometrics will at some point do an analysis.

I've been getting an increasing number of interview requests from reporters and book writers (stemming from my connection with Bitcoin). In the interest of being lazy, instead of doing more private interviews I figure I'd create an entry here and let them ask questions publicly, so I can avoid having to answer redundant questions. I'm also open to answering any other questions of LW interest here.

In preparation for this AMA, I've updated my script for retrieving and sorting all comments and posts of a given LW user, to also allow filtering by keyword or regex. So you can go to http://www.ibiblio.org/weidai/lesswrong_user.php, enter my username "Wei_Dai", then (when the page finishes loading) enter "bitcoin" in the "filter by" box to see all of my comments/posts that mention Bitcoin.

I was asking a serious question.

I sometimes wonder if Bitcoin was invented not so much to become the global reserve digital cash currency, but to prove to others that the technology can work. It was more gateway rather than final destination

Have you read Satoshi's original emails?

1 - I didn't take any steps to code up b-money. Part of it was because b-money wasn't a complete practical design yet, but I didn't continue to work on the design because I had actually grown somewhat disillusioned with cryptoanarchy by the time I finished writing up b-money, and I didn't foresee that a system like it, once implemented, could attract so much attention and use beyond a small group of hardcore cypherpunks.

2 - It's hard for me to tell, but I'd guess that it was probably a mixture of technical challenge and wanting to change the world.

3 and 4 - Don't have much to say on these. Others have probably thought much more about these questions over the past months and years and are more qualified than I am to answer.

5 - I haven't seen any indication of this. What makes you suspect it?
