> So, the great amazing disruptive technology that is going to completely change the world... broke as soon as a tiny fraction of the world start paying any attention to it. This is shifting the goalposts massively. The original comment was that there was no use-case for Blockchain. You are also talking about a component of cryptocurrencies as if they were the whole. The issue with the viability of cryptocurrencies is not tied to the blockchain but rather human investor behaviour. > Literally none of those applications require blockchain, and blockchain solves literally none of the problems in those domains. I'm not sure what you've imagined the applications in question are but you appear to have invented them and decided they don't work; I didn't provide any specific examples. If you want a specific example of where it's addressing things and is being put to use: Provenance. If you don't mind a bit of dry reading the ieee has a decent writeup on the value this provides and the problems it can address: https://ieeexplore.ieee.org/document/8909921 https://ieeexplore.ieee.org/document/8909921

Indeed, you didn't. Because blockchain apologists very rarely do, since for 100% of cases the proposed blockchain solution doesn't solve the posited problem. What you did say though was "Then there's the applications for areas like logistics, supply chain, that are all under development".

Let me quote from an article [1] === start quote === An illustration of the difference: In 2006, Walmart launched a system to track its bananas and mangoes from field to store. In 2009 they abandoned it because of logistical problems getting everyone to enter the data, and in 2017 they re-launched it (to much fanfare) on blockchain. If someone comes to you with “the mango-pickers don’t like doing data entry,” “I know: let’s create a very long sequence of small files, each one containing a hash of the previous file” is a nonsense answer, but “What if everyone keeps their records in a tamper-proof repository not owned by anyone?” at least addresses the right question! ... It’s true that tampering with data stored on a blockchain is hard, but it’s false that blockchain is a good way to create data that has integrity. ... Blockchain systems do not magically make the data in them accurate or the people entering the data trustworthy, they merely enable you to audit whether it has been tampered with. A person who sprayed pesticides on a mango can still enter onto a blockchain system that the mangoes were organic. === end quote === Bute yeah, the article does have a high "bullshit hype per number of words" ratio: Blockchain!
