Poll: How many of you did actually read Satoshi's paper?

[hahahafr]

I was wondering that, I'm into Bitcoin since 2012 but didn't actually read it.

Can someone post an accurate précis please so I can bluff my way through this question the next time I'm asked?

[niko]

Try reading it. Surprisingly, there is very little technical detail, only broad strokes. Most of Bitcoin has been invented and developed by Satoshi and many others, after the paper was published.

Someone should post it here.

This is the paper that convinced me that Bitcoin was legit. Read it many times since then.

Haven't read it yet but will be in the next couple weeks.

[freedomno1]

Read it said Damn got interested

[TippingPoint]

I have read it, and I imagine that a high percentage of the people who spend time in this forum have read it, but do we expect all future users of Bitcoin to read it?  Do most people read the terms of their credit card agreement, or even their mortgage?  Do they read all the warnings that come with their computer?

[lixiaolai]

I repeatedly read this paper, and it's a masterpiece.

[ffssixtynine]

Yep, and so should everyone else. It's pretty easy to understand and gives you an insight into how the fundamentals work.

[Rampion]

It's a genius work. The real question is the following: who didn't read YET the fundational paper of BTC? Go read it, then.

[Damme]

somehow voted no  -> yes!

Satoshi trivia: he wrote Bitcoin's code and THEN he wrote the paper.

I actually did this kind of backwards.  I had to write all the code before I could convince myself that I could solve every
problem, then I wrote the paper.  I think I will be able to release the code sooner than I could write a detailed spec.

I found that mailing-list thread to be as good a read as the white-paper. A must-read in bitcoin-land, IMO.

Satoshi has got a unique writing style, on one hand he is very concise and to the point, my favorite:"The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes." On the other hand he is not as rigorous as many academics when it comes to language, and he didn't easily throw around terminologies and jargons, like he can't be bothered with it. I am not sure if he invented this writing style as a camouflage and if not, how difficult it is to use pattern-matching to uncover his real identity(not that I want to).

It is actually quite interesting on a number of levels.

Normally such a paper would be frowned upon, because most of the citations are at least 10 years out of date and as for going back to 1957 for reference material... very dodgy..... esp. as there has been a lot of work in probability theory since then.

It is as if the citations were 'thrown' in as an afterthought with an underlying lack of research.

Yeah, the 1957 one was supposedly the probability textbook he used, it's like saying:"I happened to have this book on my desk so that's what I used", he didn't make any attempt to put up any pretense to make it look better.

Agreed. His explanation of the blockchain is classic for its conciseness:

I'm quoting this wonderful piece of text from the mailing list:

James A. Donald wrote:

The proof-of-work chain is a solution to the Byzantine Generals' Problem.  I'll
try to rephrase it in that context.

A number of Byzantine Generals each have a computer and want to attack the
King's wi-fi by brute forcing the password, which they've learned is a certain
number of characters in length.  Once they stimulate the network to generate a
packet, they must crack the password within a limited time to break in and
erase the logs, otherwise they will be discovered and get in trouble.  They
only have enough CPU power to crack it fast enough if a majority of them attack
at the same time.

They don't particularly care when the attack will be, just that they all agree.
 It has been decided that anyone who feels like it will announce a time, and
whatever time is heard first will be the official attack time.  The problem is
that the network is not instantaneous, and if two generals announce different
attack times at close to the same time, some may hear one first and others hear
the other first.

They use a proof-of-work chain to solve the problem.  Once each general
receives whatever attack time he hears first, he sets his computer to solve an
extremely difficult proof-of-work problem that includes the attack time in its
hash.  The proof-of-work is so difficult, it's expected to take 10 minutes of
them all working at once before one of them finds a solution.  Once one of the
generals finds a proof-of-work, he broadcasts it to the network, and everyone
changes their current proof-of-work computation to include that proof-of-work
in the hash they're working on.  If anyone was working on a different attack
time, they switch to this one, because its proof-of-work chain is now longer.

After two hours, one attack time should be hashed by a chain of 12
proofs-of-work.  Every general, just by verifying the difficulty of the
proof-of-work chain, can estimate how much parallel CPU power per hour was
expended on it and see that it must have required the majority of the computers
to produce that much proof-of-work in the allotted time.  They had to all have
seen it because the proof-of-work is proof that they worked on it.  If the CPU
power exhibited by the proof-of-work chain is sufficient to crack the password,
they can safely attack at the agreed time.

The proof-of-work chain is how all the synchronisation, distributed database
and global view problems you've asked about are solved.
