Satoshi ↔ Adam Back Correspondence

I’m getting ready to release a paper that expands on your ideas into a complete working system.

I wanted to make sure I have the citation to your hashcash paper right.

[Satoshi included a link to a pre-release draft of what would become the Bitcoin whitepaper. The draft was titled “Electronic Cash Without a Trusted Third Party” and filed as ecash.pdf — predating the October 3 draft which was retitled to “Bitcoin: A Peer-to-Peer Electronic Cash System.”]

[Source: This email was entered into evidence during the COPA v. Craig Wright trial in London, February 2024. Adam Back filed the complete email chain as a witness statement.]

[Adam Back confirmed the citation and suggested Satoshi look at Wei Dai’s b-money proposal.]

[Satoshi subsequently replied: “Thanks, I wasn’t aware of the b-money page, but my ideas start from exactly that point.” He then contacted Wei Dai directly on August 22, 2008, and cited b-money in the Bitcoin whitepaper.]

Only the first two emails (Satoshi’s initial contact and Back’s reply) are archived here; the remaining three have not been published in full.]
