Musk addressed the mystery of the bitcoin creator's identity during a podcast published Tuesday. During the appearance, the host asked whether it was a "feature or a bug" that bitcoin's creator has never revealed themselves, prompting Musk to provide his theory on the situation.

A prominent cryptocurrency advocate, Musk argued that computer scientist Nick Szabo is most "responsible" for bitcoin's development.

However, he stopped short of naming him as the creator of the cryptocurrency itself.

"You can look at the evolution of ideas before the launch of bitcoin and see who wrote about those ideas," Musk said on the Lex Fridman podcast.

"Obviously I don't know who created bitcoin for practical purposes, but the evolution of ideas is pretty clear before that. It seems as though Nick Szabo is probably, more than anybody else, responsible for the evolution of those ideas."

"He claims not to be Nakamoto but that's neither here nor there. He seems to be the one more responsible for the ideas behind bitcoin than anyone else," Musk added.

Szabo has long been viewed as a potential candidate for Nakamoto. The computer scientist created a bitcoin predecessor called "bit gold" in the late 1990s.
