This is a really nice explanation. Thanks for writing. I listened to the Walmart+IBM talk on supply chain a while back, and one question I still have is — can’t you solve this problem more easily with centralized tech? If I’m Walmart and I can dictate terms to upstream suppliers, why don’t I just build an app with a conventional ledger and make everyone use it? The odds of that middle party that wants to lie being a high end hacker and forging data in the database are slim, no?
