Abstract: Computer-implemented digital communication using cryptography is disclosed. The computer-implemented methods are used to perform digital communication for minting and transfer of digital commodities using short message service (SMS) messages. The cryptographic system disclosed generates graphical user interfaces and executes operations on a backend apparatus. When the backend apparatus receives the SMS messages, the backend apparatus retrieves the digital commodities and interacts with a storage apparatus to store the digital commodities, identified by a uniform resource locator (URL).

Abstract: Systems and methods for authenticating products, such as products from original manufacturers and/or resellers, that provide a trusted and reliable mechanism for buyers and sellers to prove the authenticity of a product and for authenticators to establish an authentication that can be relied on during downstream transactions is provided. In some embodiments, a blockchain-based product authentication system is provided that allows entities within a chain of commerce (e.g., suppliers, manufacturers, distributors, retails, consumers, consignors, resellers) to verify the authenticity of items by way of trusted authenticators and trusted audit processes. The product authentication system enables users to rely on product authentications via off-channel sales with the use of cryptography, blockchain, digital assets, and tagging hardware and software.
