Blockchain study finds zero success rate and vendors don't call back
Blockchains make no sense when the &quot;asset&quot; they are tracking have to be imported from the outside world because they lose the trustless property which is the whole point.<p>For example supply line tracking blockchains. &quot;Look this piece of beef was at place X on time Y with temperature Z, I have a hash and everything&quot;. Yes but how do I know that you didn&#x27;t swap the barcodes or you didn&#x27;t fiddle with the GPS or the thermometer was working or a million other things ?<p>Blockchain only makes sense if the asset is internal (i.e it gets created in it) because that makes it publicly auditable and you don&#x27;t have to trust anyone. Cryptocurrency is the perfect use case and the reason they were invented.
