Although more than one alleged Nakamoto has appeared in recent years, they have ended up described as fraud and without sufficient evidence. Theories are not lacking, and this one by Mark Essien, a Nigerian developer who published his list of "evidences" on his personal blog, suggests that Satoshi Nakamoto is actually Bram Cohen, the founder of BitTorrent.
What we know about Nakamoto:
Satoshi Nakamoto is the name used by those who designed bitcoin, implemented the first blockchain and deployed the first decentralized cryptocurrency. In 2008, this being published a document describing the bitcoin and said that he had started writing the code in 2007.
In a profile on P2P Foundation, Nakamoto said he was a man living in Japan and was born on April 5, 1975. He created the bitcointalk forum and posted the first message in 2009 under the pseudonym satoshi.
Nakamoto created bitcoin.org and continued to collaborate with other developers in bitcoin until mid-2010. The bitcoin public transactions record shows that Nakamoto's address contains approximately one million bitcoins.
Few in the world could be Satoshi.
Knowing all this, Essien based his theory that there are only a handful of people in the world with the necessary skills to have created the bitcoin. And, by taking into account those specific skills and the information we have about Nakamoto, Bram Cohen ends up fitting very well into the profile.
It is very unlikely that bitcoin is the first software that its creator has published. It could not have been his first hit.
For Essien, Satoshi has to be a person between 35 and 50 years old, who has been active on Usenet, shown interest in HashCash or any monetary platform on the Internet in the past, and who has developed software for Windows in a professional manner.
Someone who has also shown interest in mathematics, physics, encryption and computational algorithms. And, he has written some important software in the past, bitcoin was not his first hit.
In his article, Essien cites a Usenet discussion that Bram Cohen had in 2000 (9 years before the release of bitcoin) with the creator of HashCash, a system that has been described as an inspiration for bitcoin.
The name of the Cohen website: BitConjurer.org.
Essien then goes on to expose a list of things that link Satoshi to Bram Cohen:
Bram was born in 1975, Satoshi said he was born in 1975.
Bram invented some successful software called BitTorrent, so that's where the experience is.
Bram is from a time when it was common to name variables in a certain way in Windows, basically writing code with the same Satoshi style.
Bram was expelled as CEO of BitTorrent in 2005, and the Bitcoin.org domain was registered in 2008. Three years would be more or less the time needed to develop this.
Bram has shown regular interest in encryption, math, and algorithms.
When Satoshi started posting about bitcoin, Bram's posts on his blog were drastically reduced.
Bram wrote a post about hiding online in 2010, which shows that he has been interested in online camouflage.
Both Bram and Satoshi were talking about digital signatures in 2009
It may be that Essien is seeing a relationship where there is not and it is mere coincidences, he admits that everything is circumstantial and in reality there is no proof of anything.
Its main argument is based on the assumption that there are few people with the necessary gifts to have invented the bitcoin and that there are no clues of them online. They have also shown interest in the subject as far back as in the year 2000, and that they share similar opinions as Bram and Satoshi, and that they have also published other software before.
