Let's finish this endless argument; "Who is Satoshi Nakamoto?". I have crystal-clear reasons that Satoshi Nakamoto is Isamu Kaneko, the creator of Winny. First of all, we have four clues to identify Satoshi Nakamoto.

He developed Bitcoin and released 2009, and he was running the mining for Bitcoin within a year by alone
He can write(not speak) in English fluently, and most of his posting time was daytime in American continent based on the research by Stefan Thomas.
He has clear and strong awareness of the current central governance system which controls our currency system.
He still don't sell his 1M BTC at all.

Isamu Kaneko's back ground as a computer scientist

Let's start from 1st one. The fact that he was the only miner for Bitcoin within a year after the initial release means he created Bitcoin "by alone". If Satoshi Nakamoto is a group of people, multi miners did exist after the initial release. Thus, his creativity as a computer scientist and his expertise as a programmer is insanely outstanding. This must be minimum requirement to identify Satoshi Nakamoto. Kaneko-san is very famous guy in Japan especially in MITOH community in which I have some friends, too.

From Wikipedia - Isamu Kaneko - Born in July 1970 and died July 6th in 2013, is a programmer and computer scientist. His speciality is about operating system and computing simulation. His last job was to run R&D to create a high performing computer in the research division for super computer in The University of Tokyo. Also he was known as code name "Mr.47" as the creator of Winny, a well-known P2P file sharing software. He was interested in programming since his elementary school days, and acquired Ph.D of Computer Science in Ibaraki University, a national university located in Ibaraki Prefecture in Japan in 1999. After graduation, he worked for The Japan Atomic Energy Agency as a postdoctoral fellow to run R&D project to simulate Earth environment. From 2000 to 2001, he joined a software development project supported by MITOH programs, also became the founder and director for Skeed, a content fire sharing software startup, and their origin came from "Winny", his innovative product. He died in July 6th in 2013 because of acute myocardial infarction. Jun Murai, the pioneer guru of internet in Japan, sent a memorial message with his will: "I'll strongly commit myself to make our world better place where innovators like him can create an amazing technology."

Yes, he is a top-tier computer scientist in the world.

Typing fluent English is not difficult for genius.

For the second, actually, there is no need this has to be himself. He can ask his real or virtual friend who can understand his mother language and is an English native speaker. So, if he had a cooperator for his project, this was the guy. However, base on my experiences to learn English, to develop the skill to "write" fluent English is much easier than to "speak" fluent English. Thus, it is possible enough for the guy like Satoshi Nakamoto, an insanely smart talent, to acquire typing in English fluently. Moreover, for those people who earned the doctoral degree and had experience to issue a patent, to write a white paper, a kind of casual thesis compared with doctoral thesis, is a peace of cake. So did I on my white paper at Orb. In addition, for a programmer who has basic skill level, it's easy to delay the timing to post his messages to the dev community to disguise his actual lifecycle. Thus, it's a cock-brained thought to assume he lives in North America base on the analysis.

Winny trials led him to get deep interest in "government"

For the third, the motivation to create Bitcoin. To me, it looks unusual for a programmer to create such product challenging currency system which is directly connected to government system. I do believe Satoshi Nakamoto must have a strong motivation to create Bitcoin based on his life experience. Like lean start-up team formation such as Steve Jobs and Steve Wozniak could be ideal, but, no idea whether he could have such amazing encounter on his life. However, for those people who tried to create an innovative product or invented such product, it is easier to imagine that programmer itself has a strong motivation to create the one. Letter press printing technology invented by Gutenberg is a good example. Thus, he must have such life experience which led him to deeply realize that we need a technology like Bitcoin in our world. And, Isamu Kaneko exactly experienced the one.

What's Winny copyright infringement criminal case?

From Wikipedia - On November 28, 2003, two Japanese users of Winny, Yoshihiro Inoue, a 41-year-old self-employed businessman from Takasaki, Gunma Prefecture and an unemployed 19-year-old from Matsuyama, were arrested by the Kyoto Prefectural Police. They were accused of sharing copyrighted material via Winny and admitted to their crimes. Shortly following the two users' arrests, Kaneko also had his home searched and had the source code of Winny confiscated by the Kyoto Police. On May 10, 2004, Kaneko was arrested for suspected conspiracy to commit copyright violation by the High-tech Crime Taskforce of the Kyoto Prefectural Police. Kaneko was released on bail on June 1, 2004. The court hearings started in September 2004 at Kyoto district court. On December 13, 2006, Kaneko was convicted of assisting copyright violations and sentenced to pay a fine of ¥1.5 million (about US$13,200). He appealed the ruling. On October 8, 2009, the guilty verdict was overturned by the Osaka High Court. On December 20, 2011, Kaneko was cleared of all charges after a panel of judges agreed that the prosecution could not prove that he had any intention to promote the software for illegal use.

Calmly thinking, we can see the reasons for the prosecutions by Kyoto Police are totally non-logical. They asserts that Isamu Kaneko intentionally help criminals to use Winny to infringe copyrights. But, in the first place, software is just a tool, thus, we can use it in either way: good or bad. Much easier use case is Samurai sword. Here is a swordsmith. And, if his sword was bought by Yakuza, and Yakuza killed the man by the sword. Could we say the swordsmith intentionally helps Yakuza kill the man because Samurai sword is clearly to kill humans, not vegetables or meets?I never heard that Japanese polices arrest swordsmith because of such reasons. How can they convince us swordsmith is not guilty but, a software creator is guilty. It's understandable that Sean Parker and Shawn Fanning, the creator of Napster, got sued by content holders on civic courts, but, it's insane that Isamu Kaneko was accused by polices on criminal trials. This is just like "Big Brother" in "1984" by George Orwell. I believe Winny trials gave Isamu Kaneko strong motivation to invent Bitcoin. Creators typically make their products based on pain points and interests which they realize in their daily life. So do I. I do believe Winny trial gave him strong interests in "government". Also, P2P technology community in Japan is very small. Isamu Kaneko knew Kenji Saito who used to be Chief Architect on Orb, and also the creator of i-WAT, next generation P2P based barter trading system of economic resources also supported by MITOH programs. i-WAT was the digitalization of WAT system which was created by Eiichi Morino, a most well-known social activist of Post Capitalism and Gesell Money in Japan. I firstly knew Morino-san in the 4th year of my college study. Kenji published his paper of i-WAT in 2006. Just during the moment of Winny trials. But, Kenji did not know that Isamu Kaneko was working on Bitcoin because Kenji was not the initial minor of Bitcoin. However, Kenji used to told me that when he researched the technology of Bitcoin, especially blockchain, "looks like blockchain was inspired by i-WAT". Thus, it must be right Isamu Kaneko deeply researched i-WAT. I do believe that Isamu Kaneko naturally realize that government system and currency system is closely connected each other on their past historical development by researching Kenji's work.

Kenji Saito - Senior Fellow at Keio University SFC Research Institute.He was born in 1964. He acquired MS of Computer Science in Cornell University in 1993 and Ph.D of Media and Governance in Keio University in 2006. He used to work for Hitachi Solutions. In 2003, he started to digitalize community currency system named "WAT system" created by Eiichi Morino by using P2P technology, and published his doctoral paper -"Internet based WAT system", and developed the software supported by MITOH program.

Eiichi Morino, he is well-known social activist for Post Capitalism and Gesell Money. Since he does not actively show himself on mass media, we don't have much information about him, but, here is the URL for his research project about Silvio Gesell Gesell Research Institute

From Wikipedia - Silvio Gesell (German: [ɡəˈzɛl]; 17 March 1862 – 11 March 1930) was a German merchant, theoretical economist, social activist, Georgist, anarchist, libertarian socialist, and founder of Freiwirtschaft. In 1900 he founded the magazine Geld-und Bodenreform (Monetary and Land Reform), but it soon closed for financial reasons. During one of his stays in Argentina, where he lived in a vegetarian commune, Gesell started the magazine Der Physiokrat together with Georg Blumenthal. In 1914, it closed due to censorship. The Bavarian Soviet Republic, in which he participated, had a violent end and Gesell was detained for several months on a charge of treason, but was acquitted by a Munich court after a speech he gave in his own defence.

Here is also an episode which showed his responsible attitude toward content publishing industry for his creation. In September 2005, he applied the patent: the idea to enable users to identify whether a specific content is distributed by original servers by applying digital signature and public key and private key based verification system. This patent was finally approved by November 2009. The genesis block of Bitcoin was mined in January 2009, and his patent based on digital signature and key based transaction verification was applied by him in September 2005, thus, I believe he created Bitcoin by leveraging his patent idea. It is very natural for me to think Isamu Kaneko has enough technical capability and expertise to create Bitcoin by alone with his achievement in creating Winny which has strong anonymousness and his patent idea of digital signature and key based verification model. Especially, his patent idea - to identify the original source of published contents by the rule that all publishing contents must publicly broadcast their information toward all nodes on P2P network, thus, anyone in the network can clearly identify the original of contents, is very close to the idea of blockchain to avoid double spending attack on Bitcoin. When I found his patent idea, I finally convinced myself that he is Satoshi Nakamoto. Also, since he released Winny with anonymous name "Mr. 47", it is natural for him to take the same way for Bitcoin with his considering Japanese government attitude toward him. Therefore, he make Satoshi Nakamoto just look like a group of people and they will be non-Japanese. Then, In March 2013, bank deposit blockade in Cyprus finally initiated serious capital flight into Bitcoin. He would be extremely surprised and excited with this incident because this is exactly he had imagined by creating Bitcoin. If you wanna deeply understand his death by heart attack, you should read the Old Testament which described many episodes with "God only knows". But, when I realized Kaneko-san is Satoshi Nakamoto, one phrase stroke into my mind - "I believe Japan will initiate actions to solve our fundamental problems of money" by Michael Ende.

From Wikipedia - Michael Andreas Helmuth Ende (12 November 1929 – 28 August 1995) was a German writer of fantasy and children's fiction. He is best known for his epic fantasy The Neverending Story; other famous works include Momo and Jim Button and Luke the Engine Driver. His works have been translated into more than 40 languages, sold more than 35 million copies, and adapted as motion pictures, stage plays, operas and audio books. Ende is one of the most popular and famous German authors of the 20th century, mostly due to the enormous success of his children's fiction. He was not strictly a children's writer, however, as he wrote books for adults too. Ende's writing could be described as a surreal mixture of reality and fantasy.

His last creation was "The last word by Ende" on NHK in 1999 in Japan. This was very first time for me to think about Post Capitalism in the 4th year of my college study. I could say this TV program set my life direction. In the show, he introduced us the idea of natural depreciation currency and free land theory created by Silvio Gesell. Ende's TV program moved Eiichi Morino to create community currency WAT system. Then, his idea inspired Kenji Saito to create Internet based WAT system, then finally the idea bore fruit as Bitcoin invented by Isamu Kaneko. All are "connecting dot" story in small world.

Died man cannot sell his 1 million BTC

Thus, it is natural that Satoshi Nakamoto don't or can't sell 1 million BTC with his private keys because he is not here. To me, all people who are self-proclaimed "Satoshi Nakamoto" are completely a lie. It extremely sound strange that the creator of Bitcoin who is enormously talented computer scientist who loves anonymity lost his private keys, isn't it? But, if the creator already passed away before the media was starting to chase him, it is very natural that he never show up himself or sell his 1 million BTC. Some wanna find out his private keys. This reminds me James Halliday, the creator of OASIS, in Ready Player One directed by Steven Spielberg in 2018. But, I do believe the thing is "God only knows".

With the memory of Isamu Kaneko

I do believe the invention of Bitcoin and blockchain is social innovation bear comparison with Letter Press Printing Technology invented by Gutenberg. Because, with his blockchain, human civilization started shifting into completely new paradigm of social system. It deserves as "world 1st innovation in millennium century". To me, that was quite unfortunate I could not get a chance to encounter with him. But, my heart and my will is always with his soul.
