I like this idea so much. The problem is quality control.
Uber Eats here in UK really struggles to delivery an accurate order. And where there is a problem the driver blames the restaurant, the restaurant blames the driver, and Uber or the restaurant (it’s frequently not clear where to begin) may or may not issue a refund and perhaps an apology, but that doesn’t solve the problem which is you don’t have the food you were promised and that you paid for. No one takes responsibility for that.
Who in a decentralised system can or should take responsibility?
Amazon, for all their many faults, claim to be trying to make the most customer-centric company on earth. A lot of their early success came from a stellar returns policy, shouldering responsibility for products they dispatched, as well as excellent prices. Not so much now, but certainly during their incredible retail growth period.
How do you code for that in a federated system? And, if you can, how do you compete in a wider marketplace with an Amazon monolith?
Is this just the backend, or is it UI too? Is there an easy way to find this out myself in future?
