Couple weeks ago I woke up and started wandering who and when the term blockchain was first used to describe the technology behind bitcoin. There is a lot of history about blockchain on the internet, but I'm curious when the term blockchain first started being used, and who called it blockchain? Was it an expert such as Nick Szabo? Was it the bitcointalk community?
I've read the bitcoin white paper numerous times, and I know Satoshi does not refer to it as blockchain, though he does use both terms block and chain in his paper.
I've also read Mastering Bitcoin by Andreas M. Antonopouos, and though chapter 9 is dedicated to blockchain, Andreas focus is on construction of the blockchain, and not where it came from.
I've also reviewed all the sources that the Bitcoin white paper references, and none of them use the term blockchain. Though many would agree the paper, "S. Haber, W.S. Stornetta, "How to time-stamp a digital document," In Journal of Cryptology, vol 3, no 2, pages 99-111, 1991." is an early form of blockchain.
I've searched bitcointalk, bitcoin wiki, and even watched Banking on Bitcoin but did not find what I was looking for.
Google search has given me multiple articles which all talk about "experts" beginning to shift focus from bitcoin to blockchain around 2014. But this does not answer my questions.
Can somebody point me in the right direction so I can finally sleep again?
Thanks!!
