Reddit users have been looking back with no small amount of nostalgia at a forum post by the Bitcoin (BTC) founder Satoshi Nakomoto that dates back to August 7, 2010 – and sees the network architect change a skeptic’s mind about the energy efficiency of mining BTC.
The post comes from the Bitcoin Talk forum, in a thread created by a user named Gridecoin.
In their original post, Gridecoin opined that while they considered BTC to be a worthy project, energy issues would likely plague it.
“The marginal cost of gold mining tends to stay near the price of gold. Gold mining is a waste, but that waste is far less than the utility of having gold available as a medium of exchange. I think the case will be the same for Bitcoin. The utility of the exchanges made possible by Bitcoin will far exceed the cost of electricity used. Therefore, not having Bitcoin would be the net waste.”
And Nakomoto went on to defend Bitcoin’s proof-of-work model. However, Gridecoin disagreed with the idea that the very high computational burden of coin generation is in fact a necessity of the current system:
“As I understand it, currency creation is fundamentally metered by time – and if that is the fundamental controlling variable, what is the need for everyone to ‘roll as many dice as possible’ within that given time period? The ‘chain of proof’ for coin ownership and transactions doesn’t depend on the method for spawning coins.”
But the BTC founder responded that “Proof-of-work has the nice property that it can be relayed through untrusted middlemen. We don’t have to worry about a chain of custody of communication. It doesn’t matter who tells you a longest chain, the proof-of-work speaks for itself.”
And that drew a positive response from Gridecoin, who wrote,
“I love that proper conversation and change of opinion was still possible in 2010. Discussions were not motivated by political bias and ultimately ending in ad hominems, but by the actual will to learn and understand things. It is so refreshing to look back at.”
