you’ve just demonstrated your lack of depth of understanding of blockchains. congratulations, your opinion was correct about 15 years ago. the technology has moved on
and the “solutions” are all objectively worse security wise. And by thinking blockchains need proof of anything, you too misunderstand what a blockchain even is. Proof of whatever is needed by the concensus algorithm, not the blockchain.
no; they all have trade-offs and that’s different… you can have trust less proof amongst semi-trusted parties like a consortium of banks: they don’t entirely trust each other, but trust each other enough to keep an eye on the other members of the consortium
there are plenty of situations like this that are non-public
they are objectively, mathematically weaker.
Joining ethereum now implies trusting a complete stranger to get you up to speed. It is objectively subjective.
You say so but I guess it’s hard to convince a lot of people who recognize it’s folly to try to fix a social/human problem with a technological solution.
Git is a merkle-tree based system like a blockchain. People have no problem with the tech. They’re just tired of the hype train.
