Bitcoin cannot be secured by public-key cryptography

Bloomberg columnist Noah Smith wrote an article[1]Bloomberg paywall link. about Bitcoin’s energy consumption. “Blogger” Nic Carter wrote a rebuttal to it. Noah Smith wrote a rebuttal to this rebuttal. Noah’s counter-rebuttal calls for its own rebuttal. Eventually, we will see why the following tweet from Nic follows quite naturally. “Proof-of-stake is just a fancy name for “exactly the same system that bitcoin was designed to be an alternative to”. – tweet by Nic Carter. ...

On NFT’s

In 1996, a federal mint employee was eating bananas near where US dollar bills were being printed, and a Del Monte sticker on one of the bananas fell into the printing press and got under a transparent layer of a $20 bill.

Of course, I am not talking about its price as measured in USD or INR. I am talking about the entire Bitcoin system, or Bitcoin, the protocol. Bitcoin is stagnant, ossified, set-in-stone, resistant-to-change, and any number of such synonyms you can look up in a thesaurus. There are a few obvious questions that come out of this: ...
