Is there any analysis out there about how well these systems work, and why a blockchain works better than a traditional inventory management system? All I can find on these implementations are by blockchain startups who have a pretty obvious interest in making blockchain solution look good. But…how is this better than a good old database? They say “trust”, and I guess that’s true in the sense you can verify the changes to the ledger. But isn’t the lack of trust in the original producers? How is it more trustworthy if they catalog this with a blockchain versus a database?
