Tsutomu Shimomura / satoshi nakamoto ?
A Japanese citizen, Shimomura was raised in Princeton, New Jersey. He lives in the San Diego.
One of the first
white hat, he has consulted with a number of government agencies on security and computer crime issues.

1984 he worked at Thinking Machines Corporation, helping the Cambridge, Mass.-based massively parallel computer start-up company design a disk system to support the rapid movement of vast databases.
This company was latter taken over by sun microsystems and later by oracle. They where specializing in data mining soft and hardware.
Shimomura assisted Hasslacher in developing a radical approach to simulating the flow of fluids based on a new model of computation, known as lattice gas automata.
Where first mention of "data block" emerges.
Kevin Mitnick case may have triggered some second thoughts, remorse in him which resulted
in non profit work on blockchain technology

Just my personal speculation.
In my opinion Shimomura was probably has some important part in developing the bitcoin technology. Since it is very possible that the name Satoshi Nakamoto is actually a group of developers and not a single individual. But if he is part of the team he should make some innovations to solve the current issues on bitcoin so it could be useful to local shops when the confirmation will become more faster.
