Eine bisher unveröffentlichte E-Mail des unbekannten Schöpfers gewährt einen Einblick in dessen Inspiration und Bitcoins frühe Tage.
Bis heute ist die wahre Identität des Bitcoin-Gründers Satoshi Nakamoto ein Mysterium. Die wenigen Anhaltspunkte zu seiner Person: E-Mails und Foren-Beiträge, die er bis zu seinem Verschwinden im Jahr 2011 verfasste. Eine jüngst aufgetauchte E-Mail offenbart nun mehr über die zuvor wenig bekannte Entstehungsgeschichte von Bitcoin. Es ist das älteste, bekannte Schriftstück des Bitcoin-Gründers. Eine Nachricht vom 22. August 2008 an Wei Dai.

Wenige Monate später, am 31. Oktober 2008, veröffentlichte er das Whitepaper zu Bitcoin. Einen ersten Entwurf davon fügte er der Mail an Dai hinzu.

Subject: Citation of your b-money page
I was very interested to read your b-money page. I'm getting ready to
release a paper that expands on your ideas into a complete working system.
Adam Back (hashcash.org) noticed the similarities and pointed me to your
site.
I need to find out the year of publication of your b-money page for the
citation in my paper. It'll look like:
[1] W. Dai, "b-money," http://www.weidai.com/bmoney.txt, (2006?).

anyone else you think would be interested.
Title: Electronic Cash Without a Trusted Third Party
Abstract: A purely peer-to-peer version of electronic cash would allow
online payments to be sent directly from one party to another without the
burdens of going through a financial institution. Digital signatures
offer part of the solution, but the main benefits are lost if a trusted
party is still required to prevent double-spending. We propose a solution
to the double-spending problem using a peer-to-peer network. The network
timestamps transactions by hashing them into an ongoing chain of
hash-based proof-of-work, forming a record that cannot be changed without
redoing the proof-of-work. The longest chain not only serves as proof of
the sequence of events witnessed, but proof that it came from the largest
pool of CPU power. As long as honest nodes control the most CPU power on
the network, they can generate the longest chain and outpace any
attackers. The network itself requires minimal structure. Messages are
broadcasted on a best effort basis, and nodes can leave and rejoin the
network at will, accepting the longest proof-of-work chain as proof of
what happened while they were gone.
