The person that has the info can use any reliable escrow they want and I will transfer the BST to the escrow. Once the info is passed to me I will be allowed 48 hours to verify it before escrow can release the BST. If it does not check out then escrow can proceed with giving the submitting person time to prove that it is.
Wait, what? You're getting the info before releasing the escrow funds? That's not how escrow works buddy

Well i certainly am not stupid enough to take the word of the person submitting the info. Besides, the submitting person can use an escrow agent they trust.
