You don't need to know all the details, because time and time again I have seen blockchain hyped up by people who don't fully understand it (or who are selling it) and the following runs it's course:

1. People get excited about blockchain because it's the "it thing" and people have some vague notion that it can apply to a distributed trust problem.

2. In nearly all cases, blockchain is a poor solution for the actual business need. This article, https://blog.smartdec.net/you-do-not-need-blockchain-eight-p... , which was discussed at length on HN a couple months ago, has a detailed section on why blockchain is a bad fit for "object authenticity guarantee".

3. So then what happens is people usually basically end up solving their use case with a kind of "franken-private blockchain" that more often than not is just a cryptographically signed ledger DB.

So yeah, I don't really care if the CTO is Jesus, as far as everything described in the article (which basically just describes a used-goods marketplace, gosh I've never heard of those before), blockchain is a "marketing-speak" solution.

Here is why EY believe in blockchain so much. Maybe it will change your view a bit:
