Abstract:
In some examples, an article may include a layer having a first surface marked with a first code. The article may include a second surface marked with a second code, the second code obscured by the layer to be unreadable through the layer. The first code and the second code may be associated in transaction data stored by a blockchain managed by a consensus network of nodes.
