An Efficient Divisible Electronic Cash Scheme

A “divisible” coin worth some amount of money, say $x, is a coin that can
be spent many times as long aa the sum total of all its the transactions does
not exceed $x. This property, divisibility, is very useful and convenient for a

Bit Commitment Schemes

Finally U proves to B that a value is correctly generated without revealing
committed information, by using some protocols to be described later.
To set up the commitment scheme, B generates prime P satisfying P - 1 =
2-Prime (Prime is a prime number), G and g whose orders in the multiplicative
group 25 are Prime. B sends P, G and g. U checks whether Prime = (P- 1)/2
is a prime by a probabilistic primality (or composite) test, and whether the orders
of G and g are Prime by checking that they are not 1 and GPrime E 1 (mod P)
U can commit to any integer s E Zprime by choosing R uniformly at random
and gPrime = - 1. (mod P).
in ZPrime and computing the commitment

What the fuck does this sound like? A computationally complex calculation, that anyone can easily verify, yet as it is a hash of the block other people cannot use your proof of work.

Detection of Overspending
Although, formally, the security including the detection of overspending is de-
scribed in Section 6, in this subsection, we will describe the detection procedure
of overspending.

You will shit your pants if you look at who wrote this paper:

Hmm this make my thought about bitcoin develop by NSA more concrete.

In cryptography, SHA-1 is a cryptographic hash function designed by the United States National Security Agency and published by the United States NIST as a U.S. Federal Information Processing Standard. SHA stands for "secure hash algorithm". The four SHA algorithms are structured differently and are distinguished as SHA-0, SHA-1, SHA-2, and SHA-3. SHA-1 is very similar to SHA-0, but corrects an error in the original SHA hash specification that led to significant weaknesses. The SHA-0 algorithm was not adopted by many applications. SHA-2 on the other hand significantly differs from the SHA-1 hash function.

There is another thread on this topic:  Tatsuaki Okamoto = Satoshi Nakamoto?

Newsflash; NSA is good at cryptography

Do you think it is just a coincidence that Satoshi and D.B. Cooper have never been seen together?  The plot thickens.

I cant see Satoshi jumping out of a plane, but anything is possible.

Nice to see Satoshi isnt just some random guy afterall bitcoins were invented for a different purpose than we originally thought. 

[franky1]

MIT, NSA, private individuals, businesses, hobbyists have all over the last few decades been trying to make electronic money. but one thing that the article the OP is trying to link to bitcoin is missing, is in 5.1 the crucial part.

the part that separates egold from bitcoin.
5.1 (or any of the paper for that matter) DOES NOT mention the whole peer-to-peer decentralization of the ledger as the double spend solution. neither does it mention mining/block creation. the MIT/NSA paper simply mentions a SQL centralized database.

this decentralized blockchain is the fundamental part that separates bitcoin from any other e-currency ever invented or theorized. and as such you might as well be shouting that e-gold was an NSA invention.

its public knowledge that 'satoshi' grabbed idea's and collaborated with other people, such as collaborated with hal finney, gavin andressen etc. and they grabbed idea's and concepts from nick szabo, and others, maybe even grabbed idea's from the 1996 nsa invention. but it was 'satoshi' that used all of these idea's and the idea of bittorrent and put it all nicely together into a seamless and effective secure transaction ledger white paper.

so just because NSA talk about cryptography does not make NSA the inventors of bitcoin.

thats like saying cavemen invented the automobile, simply because they made the wheel.

Exactly. It seems like this paper was written with the intentions of BANKS issuing digital currency, not a decentralized protocol.

Well this sure is an interesting thread.   

Definitely makes you go "HMMMMMMMMMMMMMM".

And doge? It was a trap from the beginning...
