> a transparent ledger

The only useful application of crypto/blockchain tech I've ever seen simply takes advantage of the transparent ledger as a way of tracking receipts.

One of the perfect applications is in shipping and logistics where receipt validation, transparency, and certification, is an essential part of the business.

Is there somewhere that explains this concept? When I "receive" something, there still must be trust that I correctly mark it so. By that point, doesn't it require trust, and therefore you may as well just use a trusted third party data store?
