[1.0] Blockchain 101: Who

Who created blockchain?

Satoshi Nakamoto. Satoshi Nakamoto is the name used by the unknown person or persons who designed bitcoin and created its original reference implementation. As part of the implementation, they also devised the first blockchain database.


The first distributed blockchain was conceptualised by an anonymous person or group known as Satoshi Nakamoto, in 2008 and implemented the following year as a core component of the digital currency – bitcoin – where it serves as the public ledger for all transactions. The invention of the blockchain for bitcoin made it the first digital currency to solve the double spending problem without the use of a trusted authority or central server. The bitcoin design has been the inspiration for other applications.


The blockchain was first mentioned in the Bitcoin whitepaper written by Satoshi Nakamoto, which is an alias of a person or a group of persons. The blockchain is revolutionary because it solved The Byzantine Generals’ Problem.



  • In December 2015, Wired and Gizmodo announced that Satoshi Nakamoto was the pseudonym of an Australian named Craig Wright: The Bizarre Saga of Craig Wright, the Latest “Inventor of Bitcoin” - The New Yorker
  • But in May 2015, Gizmodo declared that Nick Szabo was the author: Nick Szabo Is Probably Satoshi Nakamoto
  • Back in 2011, the New Yorker published the story of a reporter on the trail of Nakamoto. The story elaborates on the logic reporters have been using to narrow the field down to a crypto expert with just the right skills: The Crypto-Currency - The New Yorker


The first work on a cryptographically secured chain of blocks was described in 1991 by Stuart Haber and W. Scott Stornetta.[16] In 1992, Bayer, Haber and Stornetta incorporated Merkle trees to the blockchain as an efficiency improvement to be able to collect several documents into one block.
