Re: Redesigning Trust: Blockchain for Supply Chains

Quite a few times I've heard the line that blockchain can revolutionize supply chains, but I still don't understand it. Since you're dealing with physical goods, you're relying on the participants of the system to enter data truthfully and accurately, which defeats the purpose of a "trustless" data store like blockchain.

You're missing the IoT component. The devices themselves do the data "entry" on the blockchain so the whole system is automated, distributed and tamper proof (assuming you don't hack the devices, of course).

I don't remember who first said it but blockchain has exactly one killer feature, Bitcoin. If you try to adapt it anywhere else you're probably abusing the tech.

I would argue that Ethereum smart contracts are much more useful than bitcoin itself. PoW, on the other hand, is a complete waste of resources.

How can you ensure the devices are not hacked though? If someone has physical access them, would it be possible to limit them from tempering with them?

But the IoT device will have to be attached to the actual good. How can you know the device is attached to the actual good and not something else?

No it's not. It all still depends on people honestly and accurately implementing the IoT component. It's just pushing the problem back a step.

All of these schemes ultimately fail because they face two challenges that inherently involved messy humanity and physical reality: the oracle problem and the enforcement problem.

But if you have to trust that the devices aren’t hacked why can’t you just use a database and give each device a private key?
