18 Years Ago, Bitcoin Arrived as One More Mailing-List Message

On October 31, 2008, Satoshi sent one more message to a cryptography list. The replies reveal skepticism, enthusiasm and the people testing Bitcoin before it had a market. Eighteen years ago today, the cryptography mailing list was talking about hash functions. A morning message weighed the cost of hardware for Skein. The preceding day's correspondence included a notice about a new SHA-3 discussion forum. At 2:10 p.m. Eastern on October 31, 2008, another message arrived. Its subject was “Bitcoin P2P e-cash paper.” The sender used the name Satoshi Nakamoto.
