# 1.3 Trust certification: know what you’re borrowing

To build confidence, users can validate their items with different levels of trust certificates. This involves registering an image of the item when they document it on the blockchain. More proof means higher trust certification:

* **Bronze**: awarded for a clear photo of the item
* **Silver**: shows the user with the item
* **Gold**: shows the user with the item, plus a receipt, to guarantee authenticity.
