This dude looks like a God. Ciro Santilli does not understand his stuff, but just based on the names of his theories, e.g. "Yoga of anabelian algebraic geometry", and on his eccentric lifestyle, it is obvious that he was in fact a God.
Alex Elbanna Updated 2025-07-16
Shady shady owner of "vistomail.com" sine November 2023. He sends emails as satoshi@vistomail.com without any disclaimers, Godlike.
He or someone with the same name is having some fun with the SEC: dockets.justia.com/docket/florida/flmdce/8:2023cv01638/416506 for "Securities Fraud".
The complaint: www.sec.gov/files/litigation/complaints/2023/comp25785.pdf (archive). Some pearls:
41. Elbanna told investors several other lies to gain investors’ trust. These included his claim that he had served in the U.S. Marines, when in reality he was discharged after just fifteen days of their thirteen-week recruit training. Elbanna claimed that he had worked at the U.S. National Security Agency (“NSA”). He further claimed that the NSA was aware of and participating in the Digital World Exchange enterprise. All of these claims were false.
42. Perhaps most incredibly, after claiming that he had “been in blockchain technology since the beginning” and “in the cryptocurrency space almost since its inception” in the May 2018 and March 2019 Whitepapers, respectively, Elbanna told investors in a chat program in April 2019 that he “was one of the first 4 creators of BTC.” He went so far as to tell another investor that he was the pseudonymous inventor of bitcoin, Satoshi Nakamoto himself. These statements were also false. Elbanna later admitted that he was not involved in blockchain technology from its beginning, and that he “didn’t even really know much about crypto” in 2018, the year he launched the Digital World Exchange enterprise.
The documentary Bitconned from Netflix comes strongly to mind, www.imdb.com/title/tt30317302/. It is unbelieveable people would fall for that kind of thing, the founders are not even sophisticated. And on top of that he agrees to appear on a documentary!!! OMG.
Algebra Updated 2025-07-16
Not to be confused with algebra over a field, which is a particular algebraic structure studied within algebra.
Algebraic number field Updated 2025-07-16
The set of all algebraic numbers forms a field.
This field contains all of the rational numbers, but it is a quadratically closed field.
Like the rationals, this field also has the same cardinality as the natural numbers, because we can specify and enumerate each of its members by a fixed number of integers from the polynomial equation that defines them. So it is a bit like the rationals, but we use potentially arbitrary numbers of integers to specify each number (polynomial coefficients + index of which root we are talking about) instead of just always two as for the rationals.
Each algebraic number also has a degree associated to it, i.e. the degree of the polynomial used to define it.
Algebraic structure Updated 2025-07-16
A set plus any number of functions , such that each satisfies some properties of choice.
Key examples:
  • group: one function
  • field: two functions
  • ring: also two functions, but with less restrictive properties
