Once the manifest has been added to the blockchain, it can no longer be altered or removed. This means that the receiver can publicly acknowledge having received the goods it paid for, and won't be able to retract that acknowledgement.

The main point is that, unlike a situation where you would be using a centralized database, there is no need to have a central trusted party to operate the database - the source of trust is distributed among the mining power of all nodes in the network.
