For example, when an item is added to a catalog system, the item information may be included in the creation element at the start of the ledger for the item. A certification authority may be included to verify that items received correspond to the item included in the catalog based on one or more certification rules. If a certification rule is satisfied, a record may be added to indicate transfer of the item from a provider to the catalog system. The certification information may be dynamically presented with item description information such as in response to searches of the catalog system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Distributed ledger certification","description":"Features are disclosed for an interface for verifiable tracking of an item through a supply chain using a distributed electronic ledger.
