In the Deadliest Catch series, did you know they can tell what temperature and time, every load was caught, from the lobster pot, to the hold, to the cannery, to the processing plant, to the grocery store. If a batch of fish goes above a set temperature they can go back and tell when, and recall the batches ahead and behind that load. This is done with block chain, it is a distributed data base that can follow the fleet and fish batches to insure quality. We can do the same thing is our factories with sensors and data bases for our spare parts, and our production materials.
A distributed data base is different from a centralized data base like our banking system which we know can be hacked and is very slow to pass data from one central system to another.
This is why a decentralized data base system is so much better to handle money transactions quicker more accurately and cheaper than our central banking system. Blockchain is what is behind the currency controls of Bitcoin and other Crypto Currencies.
