An nameless publish on the Cypherpunks mailing checklist from 21 years in the past discusses the thought of “ecash,” and the hypothesis within the crypto neighborhood is that it would belong to a pre-Bitcoin Satoshi Nakamoto.
“Cypherpunk” refers to a motion that emerged within the 1980s advocating cryptography and different privacy-enhancing applied sciences as instruments for selling social change. Lots of the early Bitcoin supporters have been a part of the Cypherpunks mailing checklist, together with Adam Again, Hal Finney, and Nick Szabo.
We have no idea with any certainty whether or not Satoshi Nakamoto was ever a part of the discussion board, however he absolutely would have been aware of the concepts percolating there. A lot of these concepts fashioned the idea for what Nakamoto finally finalized in Bitcoin.
When this outdated publish discussing “ecash” resurfaced, it was straightforward to attach the dots to present-day Bitcoin. Recall that the complete title of the Bitcoin whitepaper is “Bitcoin: A Peer-to-Peer Digital Money System.”
The nameless creator of the Cypherpunks publish discusses the mandatory stipulations of digital money, one function of which is named “blinding:”
“I would not say ecash has to make use of blinding, however I’d argue it might be a misuse of the phrase “ecash”, if one thing which was revocable have been dubbed ecash.”
“Blinding” probably refers back to the thought of a cryptographic blind signature, launched by David Chaum. It lets folks securely signal information with out revealing it, after which verifies that the information has not been tampered with. This performance has turn out to be commonplace within the wake of Bitcoin and different cryptocurrencies.
The creator of the nameless publish goes on to debate one other key impediment that any digital forex faces: the double spend drawback.
“One risk is to make the double-spending database public. Each time somebody receives a coin they broadcast its worth. The DB [database] operates in parallel throughout a lot of servers so it’s intractable to close it down.”
He concludes his publish by mentioning the 2 proposals for digital cash that have been referenced within the Bitcoin whitepaper: Wei Dai’s b-money and Adam Again’s Hashcash:
“One other doable type of ecash could possibly be primarily based on Wei Dai’s b-money. That is like hashcash, one thing which represents a measurable quantity of computational work to supply. It due to this fact cannot be cast. This could possibly be a really sturdy cost system and is price pursuing additional.”
In the midst of a 200-word publish, the nameless touches on each main situation dealing with a usable digital forex, and does so 10 years earlier than Bitcoin pulled all of them collectively. It’s definitely not sufficient to conclude that the creator is Satoshi Nakamoto, however the resemblance is hanging.
