1. A distributed network comprising:
a first node on the distributed network communicatively coupled to one or more additional nodes on the distributed network, the first node configured to:
receive information about a unique seal associated with a product in response to a query;
verify that (1) a block including information on a vendor associated with the unique seal has been appended to a distributed ledger by a trusted node, wherein the trusted node is one of the one or more additional nodes on the distributed network, and (2) the vendor is a certified vendor of the product to yield a verification, wherein the unique seal is uniquely associated with each of a plurality of vendors at different times based on movement of the product amongst the plurality of vendors through a supply chain; and
record the verification on the distributed network by updating the block to reflect the verification, wherein the block reflecting the verification is added to all nodes of the distributed network.
