Abstract: A method for exchanging loyalty points includes storing one or more user loyalty profiles including a user identifier and one or more merchant identifiers associated with a loyalty point total; receiving a transaction request from a computing system including at least a user identification, a merchant identification, and a transaction amount; identifying a user loyalty profile including a user identifier that matches the user identification; in response to identifying the user loyalty profile, determining the merchant identification matches one of the one or more merchant identifiers; determining the loyalty point total associated with the matching merchant identifier is lower than a loyalty point total required to cover the transaction amount; and exchanging a first amount of loyalty points associated with a different merchant identifier of the one or more merchant identifiers for a second amount of loyalty points associated with the merchant identifier that matched the merchant identification.

Abstract: A method and system for cross-network transactions includes a processor for storing a blockchain having a non-fungible token (NFT) associated with a physical asset, the NFT having metadata including at least a product identifier and product details. The processor may store one or more user account profiles each including a user identifier and a blockchain wallet address. The processor may receive a product verification request message including a machine-readable code from a first user computing device, execute a query on the blockchain to identify an NFT including a product identifier matching the machine-readable code and in response to identifying an NFT including a product identifier matching the machine-readable code, determine the product associated with the machine-readable code is verified. The processor may generate a verification result indicating that the product associated with the machine-readable code is verified code and transmit the verification result to the first user computing device.

Abstract: Systems and techniques for facilitating microtransactions are described. The described systems and techniques leverage certain capabilities of the blockchain while maintaining a conventional transaction experience and/or interface. A method includes receiving, at a digicent service on a blockchain, a digital currency microtransaction request to transfer a particular amount of digital currency from a first digicent wallet account to a second digicent wallet account, the microtransaction being a fractional fiat currency transaction. The digicent service verifies the digital currency microtransaction request, including by confirming that a first tokenized payment source is associated with the first digicent wallet account and exists as a valid smart contract on the blockchain; and confirming that a second tokenized payment source is associated with the second digicent wallet account and exists as a valid smart contract on the blockchain.

Abstract: A current-conducting pin for a hermetic terminal is disclosed. A bimetallic pin includes an exterior jacket of a first metal material and an interior core of a second material. A recess is formed in at least one of the opposite ends of the pin and a sealing material is disposed in the recess and hermetically seals a annular interface between the exterior jacket and the interior core of the pin.

Abstract: A power terminal feed-through includes a housing, at least one current conducting pin and a sealing glass hermetically sealing the at least one current conducting pin to the housing. The at least one current conducting pin defines a peripheral indentation in the surface of the current conducting pin. The sealing glass fills in the peripheral indentation when fused to both the current conducting pin and housing.
