Doesn't this require you to trust the source? And if you trust the source, there is no need for a blockchain?

[atq2119]

Well, even if you trust the source, you still need to be able to access the transaction records.

You don't really need a distributed ledger for that,a centralised database run by an industry clearinghouse could serve the purpose just fine.

But maybe there are cases where a distributed ledger is easier or cheaper to establish than such a clearinghouse.

It allows you to know the source, which enables you to make a data-informed decision about whether or not you trust the source.

As opposed to the current status quo, where you can never even know the source so trust doesn't even come into the picture.
