As somebody who works in the space, you've just hit a topic that annoys me to no end. The term "Blockchain" has a very specific meaning, and that is just a specific type of data structure (that also happens to be used in Git, as you describe). The whole meme around anything that's even remotely like a large scale distributed (not even decentralised, as Bitcoin is!) system being called a "blockchain" is literally worse than useless, because it has no precise meaning, and has robbed a word from a perfectly fine, well-defined meaning.

And you're proving my point...

if "blockchain" is so bad - why do I never hear any actual proposals for anything that is GOOD?

STFU about blockchain and say someting of positive impact as opposed to constantly bitching about blockchain.

I am not pushing blockchain, I am pointing out that people who "work in the space" clearly have nothing, else theyd stop saying "blockchain sucks!" and say "See, what you really want in a situation like this is..."

if this "works" why hasnt it been embraced/shown as example?

Your comment doesnt hold up to the evidence of history...

Wow, XKCD is now being cited as evidence. What a world we live in.

Hah. Not evidence... anecdotal poking of fun...

Dont take things too seriously. ;-)
