Network, method, and non-transitory computer-readable medium for certification of vendors using distributed ledger technology

A method of verifying vendors, comprising:

• receiving, at a first node on a distributed network communicatively coupled to one or more additional nodes on the distributed network, information about a unique seal associated with a product in response to a query;
• verifying 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
• recording 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.

One or more non-transitory computer-readable media comprising computer-readable instructions, which when executed by one or more processors at a first node of a distributed network, cause the first node to:

• receive information about a unique seal associated with a product in response to a query, wherein the first node is communicatively coupled to one or more additional nodes on the distributed network;
• 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.
