Consensus can also be achieved by trusting a 3rd party in a certain context. Funny that's precisely what BTC people are doing with their exchanges, with Lightning, and even with Bitmain & Cie owning the majority of the network.

Also, you should know historically the luddites were artisans who destroyed the machines (introduced by the bosses) that ruined their lives and work conditions. They were not loonies opposed to any form of technological progress. In that sense, maybe some of us from HN are in fact luddites, because we want the machine to help, not to ruin society and the environment.

Blockchain tech is unrelated to bitcoins/crypto's.

Just like Stackoverflow doesn't correlate with the value of the .Net framework or HN doesn't correlate with the value of the ARC programming language ( since it's build on that tech)

It's an example of the tech, but the value of blockchain does not have a correlation with any of the 8000 implementations as crypto.

Additionally, the implementation of El Salvador uses Lightning network and since that obfuscates transactions off-chain to a centralized authority. It's not what i'd call blockchain anymore.
