Submission Details
Severity:
The arbiter should not be either the buyer or the seller.
Summary
It is better to choose an arbiter who is neither the seller nor the buyer. If the arbiter acts as any one of them, then the integrity becomes questionable. Ensuring that the arbiter is another actor who can impartially judge both sides will give more integrity to the protocol."
