Could blockchain have solved the mystery of the romaine lettuce E. coli outbreak?

Blockchain, for all its cloak-and-dagger associations, is basically a democratized accounting system made possible by advances in data encryption. Rather than storing proprietary data behind traditional security walls, companies contribute encrypted blocks of data to a “distributed” ledger that can be monitored and verified by each farmer, packer, shipper, distributor, wholesaler and retailer of produce. No one can make a change without everyone knowing, and agreeing to it.
