Blockchain beyond bitcoin etc. - Who is mining?
These days there's a lot of new systems being shipped - or marketed even before that - that came with 'blockchain' attached somehow. We're not sure how and why someone would set up a blockchain for logistics transactions, to stay on your example. Most of the news about 'adopting blockchain technology' we see on the media fails to explain why they need a blockchan at all - or are afraid to say they will anchor data on Bitcoin or Ethereum chains.

One can design a database with hashes and digital signatures in blockchain's fashion and call that a 'blockchain', without mining. They can even have ming with no reward or token of value, and call that a 'blockchain'. There's no one to stop them.

But the meaning of 'blockchain' as it's used in Bitcoin, is something where mining is hard and needs incentives like block reward to happen. That's the design originally proposed by Satoshi Nakamoto in his solution for the Bizantine Generals Problem.
