The Creation of Bitcoin......Satoshi said he started working on it in 2007
Nick Szabo: “(assuming Nakamoto is not really Finney or Dai)”…..Only Finney (RPOW) and Nakamoto were motivated enough to actually implement such a scheme”.
There seems to be one other person with the motivation that Szabo says would be needed to create Bitcoin:
2007
Zooko quote: “I want to invent something else: a truly decentralized economic mechanism. Research that points in this direction includes the sub-field of “algorithmic mechanism design” within economic game theory, some peer-to-peer research such as GNUnet, Wei Dai’s and Nick Szabo’s ideas about “bit gold”, Nick Szabo’s “smart contracts”, and much more. Another inspiration is BitTorrent’s tit-for-tat mechanism, which is decentralized and minimal, but gets the job done within its limited problem domain.”
https://tahoe-lafs.org/pipermail/tahoe-dev/2007-June/000022.html 2007 Szabo applies BitGold(w/RPOW) and his “Scarce Object” theory to Zookos p2p hard drive node project with "Nanobarter" (THIS COMBINATION CREATES BITCOIN)
Szabo: “One possible answer to central mint vulnerability is bit gold — a currency the value of which does not depend on any particular trusted third party. Another alternative is (an object barter economy”Scarce Objects”).”
