>So it actually seems that in the logistics line of things like manufacturing / production / etc. there is a place for blockchain, mainly due to the immutability and decentralized distribution properties. What could take a whole week to track down using older methods, takes seconds if all the data is recorded on the blockchain...for example, food production. You want to find out exactly which animal your food comes from, and all the things involved (use of antibiotics? which factory? how did the product travel before ending up at your grocery store? etc.). The usual shitty dismissive HN response to this would be something like "but that doesn't require a block chain it could just be a database". To those people I would ask who is running that database? What are their incentives? Forget about the currency uses of block chains for a moment. The fact that you have this distributed network, controlled by nobody in particular but with their incentives aligned to keep it running and keep it secure, means that you have a platform you can build other stuff on top of. An Ethereum smart contract is a type of append only database, the code of which is strongly open source and very battle tested (basically everyone is using openzeppelin), where you do not have to care about where or by who it is being hosted, with an uptime that puts every hosting provider in existence today to shame.
