Satoshi emails Adam Back
Satoshi Nakamoto emailed Adam Back, the author of the hashcash paper, to check how he was citing it, and shared a draft of the whitepaper, which he said "finds a new use for hash-based proof-of-work as a way to make e-cash work". Back replied the next day, pointing him to Wei Dai's b-money proposal. The emails became public in 2024, in the UK High Court case that found Craig Wright is not Satoshi.

Satoshi emails Wei Dai
After Adam Back pointed him to it, Satoshi Nakamoto emailed Wei Dai about Dai's b-money proposal. His paper, Satoshi wrote, "expands on your ideas into a complete working system", and he asked when b-money was published so he could cite it; the Bitcoin whitepaper lists it as its first reference. The draft he linked was then titled "Electronic Cash Without a Trusted Third Party".
