Speculations are growing, but it’s almost impossible to prove.
An anonymous message on the Cypherpunks mailing list 21 years ago discusses the idea of ”e-cash” / “e-cash”. With the emergence of this message, a speculation has occurred in the crypto community. According to the speculation, this message may belong to Satoshi Nakamoto.
“Cypherpunk” was a movement that advocated cryptography and other privacy-enhancing technologies as a tool to support social change in the 1980s. Most of the early Bitcoin supporters were part of the Cypherpunks mailing list, including Adam Back, Hal Finney and Nick Szabo. We have no exact idea whether Satoshi Nakamoto is part of the forum, but he would definitely be familiar with the ideas discussed there. Many of these ideas formed the basis of what Nakamoto finally concluded in Bitcoin.
When this old article, which discusses the concept of “e-cash”, reappeared, it was easy to connect the points to today’s Bitcoin. Recall that the full name of the Bitcoin whitepaper is “Bitcoin: Peer-to-Peer Electronic Cash System”.
It talks about its features
The anonymous author of the content in Cypherpunks also talks about what is called “blinding”:
“I can’t say that e-cash has to use blinding, but if something that is reversible is called e-cash, I think it will be misuse.”
“Blinding” probably refers to the idea of cryptographic blind signature developed by David Chaum. It allows people to sign securely without disclosing the data and then verifies that the data is not tampered with. This functionality has become widespread after Bitcoin and other cryptocurrencies.
The author of the anonymous article continues to discuss another barrier facing any electronic currency: the problem of double spending. “One possibility is to make the double spending database public. Whenever someone gets money, it publishes its value. The database runs in parallel on many servers, so it’s difficult to turn it off. ”
The author concludes his article by mentioning two electronic money offers referred to in the Bitcoin white paper: Wei Dai’s b-money and Adam Back’s Hashcash.
In a 200-word article, the author addresses all the problems that Bitoin solves. Therefore, controversy continues as to whether the author is Satoshi Nakamoto.
