J'ai résumé mais Satoshi s'est fait d'un seul coup très rare puis a disparu totalement à l'instant où Finney s'arrêtait de programmer et de communiquer (à cause de sa paralysie).
Certains ont émis l'hypothèse que Satoshi était tellement affecté par la maladie de Finney qu'il a décidé de se refermer sur lui même et d'arrêter de communiquer. Cependant je trouve que l'hypothèse Satoshi=Finney est bien plus logique.

I thought I'd write about the last four years, an eventful time for Bitcoin and me.

For those who don't know me, I'm Hal Finney. I got my start in crypto working on an early version of PGP, working closely with Phil Zimmermann. When Phil decided to start PGP Corporation, I was one of the first hires. I would work on PGP until my retirement. At the same time, I got involved with the Cypherpunks. I ran the first cryptographically based anonymous remailer, among other activities.

Fast forward to late 2008 and the announcement of Bitcoin. I've noticed that cryptographic graybeards (I was in my mid 50's) tend to get cynical. I was more idealistic; I have always loved crypto, the mystery and the paradox of it.

When Satoshi announced Bitcoin on the cryptography mailing list, he got a skeptical reception at best. Cryptographers have seen too many grand schemes by clueless noobs. They tend to have a knee jerk reaction.

I was more positive. I had long been interested in cryptographic payment schemes. Plus I was lucky enough to meet and extensively correspond with both Wei Dai and Nick Szabo, generally acknowledged to have created ideas that would be realized with Bitcoin. I had made an attempt to create my own proof of work based currency, called RPOW. So I found Bitcoin facinating.

When Satoshi announced the first release of the software, I grabbed it right away. I think I was the first person besides Satoshi to run bitcoin. I mined block 70-something, and I was the recipient of the first bitcoin transaction, when Satoshi sent ten coins to me as a test. I carried on an email conversation with Satoshi over the next few days, mostly me reporting bugs and him fixing them.

Today, Satoshi's true identity has become a mystery. But at the time, I thought I was dealing with a young man of Japanese ancestry who was very smart and sincere. I've had the good fortune to know many brilliant people over the course of my life, so I recognize the signs.

Bitcoin is an implementation of Wei Dai's b-money proposal http://weidai.com/bmoney.txt on Cypherpunks http://en.wikipedia.org/wiki/Cypherpunks in 1998 and Nick Szabo's Bitgold proposal http://unenumerated.blogspot.com/2005/12/bit-gold.html

The original author of P.G.P., Philip R. Zimmermann, quickly became the target of federal prosecutors, who believed that the software broke United States laws against exporting military-grade encryption software.

While the investigation went on and became a major cause for civil libertarians, Mr. Finney played a more quiet role in P.G.P. to avoid becoming a target himself. Mr. Zimmermann said in an interview that this decision meant Mr. Finney did not get proper credit for some of the important innovations he had made in the development of P.G.P.

Well, his fictional character was much closer than it might appear. Less than two miles from his house lived another scientist named Dorian Prentice Satoshi Nakamoto. It is possible that Finney took Nakamoto’s identity to conceal his own. I mean, what are the odds that both of them lived in Temple City, a small town with just 36,000 people? One cryptographic genius and another named exactly like the creator of bitcoin: too big a coincidence?

Pas mal ta petite enquête Saint-loup ^^ Après j'ai un anglais trop pourris pour me permettre de comparer leurs styles d'écriture  

Mais d'ailleurs j'y pense, Theymos lui il sait vraiment qui est Satoshi ?

He also became the first coder to work with Phil Zimmermann on Pretty Good Privacy or PGP, the first freely available strong crypto tool, and designed the software's "web-of-trust" model of verifying PGP users' identities.

He worked almost a full-time job’s worth of hours developing PGP 2.0, widely considered to be the first truly secure version of the program, and pioneered its "web of trust" model of key-signing, a method to establish trusted identities through the peer-to-peer vouching of a community of users. "The trust model was a very complex part, and this was of crucial importance to PGP's success," says Zimmermann. "Hal made an enormous contribution."

"Hal was motivated by the highest ideals of human rights," Zimmermann said last week. Finney helped devise a "web of trust" to protect a user from being electronically impersonated.
