Blockingto

Blockchain did not give us that.

It only moved the goal post.

As long as you can't guarauntee that the data you put onto a blockchain is trustworth in the first place, whatever you put on a blockchain is not 'tamper-proof'.

Therefore the ONLY thing you can handle on a blockchain 'tamper-proof' is stuff only existing on the blockchain itself. Which means basically nothing.

And there is a second goal post which was moved: the ignorance about a blockchain being 'tamper-proof'. 51% attack are real, you don't know if a country just owns and controls a lot of nodes and the latest rumor: NSA was involved in blockchain creation. You don't know if something is hidden in the system which gives one entity an edge over others.
