Finally! He can melt all the ice-cream and destroy his customer.

No, Bob's misconduct would potentially be provable in court based on the trustless data ledgers in the blockchain.

Really, this example just shows one way how developers could use blockchain technology to develop applications that utilize trustless data.

Imagine this same technology applied to the transfer of human organs, rather than easily replaceable ice cream.

Challenge yourself to think of other scenarios in business where trustless data might make a difference.

Maybe you'll have a valuable idea in this wide open space.

I’ve heard many scenarios like “transfer of human organs” as a scenario for blockchain, but I’m skeptical that blockchain solves problems in the tangible world all that easily. It is my perception that blockchain is great for trustless information assets, but not great for trustless tangible assets.

Blockchain can’t stop a human from stealing an organ and replacing it with a different organ. Even tracking shipping containers, which was high profile a few years ago, only requires a human to make a mistake in loading a boat to throw off the database.

In tangible-world-to-information-storage scenarios, the hard part is not the information, but the guarantee that information matches the real world. In my view, the claim that blockchain solves for a trustless tangible world is naive.

[Donzo]

It's hard to imagine a solution to these problems because we are so far away from highly functional examples of this tech in action in the "real" world.

That said, engineers live to solve problems in better, smarter ways.

I personally believe it is naive to bet against innovation in this sphere, but we both shall see if we are so fortunate.

If you have trust in a court, you don't need a trustless system, by definition.

[Donzo]

Slippery slope: I can trust the court if I don't have to trust the data. I can't trust the court if I have to subjectively prove my arguments.

[vertex-four]

But you can't trust the data if the systems providing - creating - that data are tampered with, by definition!

[Donzo]

You are very interested in defining things.

This is a case where imagination is needed.
