Gmail would be just as good. Have them send you an email as part of the handoff process. Time/date/photo will be documented in a source of Truth

If you know anything about email headers, this is a bad solution. Are you suggesting that everyone has a shared Gmail account with one password? What happens when an email gets deleted?

What are you talking about? The suggestion was that the transporter simply send an email with the same data. The receiving party would get the email, and when an email is sent the sending party has no access to change it.

Yes, in that case the receiver and all other custodians in the party would need shared access to the same Gmail account, or many emails would be sent to the ever expanding list of custodians, leaving a nightmare of 1000+ email long chains of unsearchable information. It's not a feasible solution.

I suppose email is searchable, especially if it includes an order ID.

I'm not discouraging you. Just to say your blockchain backed solution is a fair solution but it's not the only solution.
