Abstract: Electronic transaction systems and methods are operable to conduct transaction verification and authorization process for an electronic transaction. An exemplary embodiment determines location of a personal electronic device of a consumer during an electronic transaction; determines location of an electronic transaction device that the consumer is using to conduct the electronic transaction; determines a distance between the personal electronic device of the consumer and the electronic transaction device; compares the determined distance with a predefined distance; and verifies and authorizes the electronic transaction when the determined distance less than or equal to the predefined distance.

Abstract: Electronic transaction systems and methods are operable to generate a plurality of branch blockchains using selected transaction information that is provided by a trunk and branch transaction block generation system. An transaction block generator system comprising a rate monitor module, a blockchain rule module, a transaction receiver module, an order module, and a block generation module is described which generates a trunk blockchain and one or more branch blockchains to overcome transaction saturation problems as well as for other reasons such as for multi-tenancy, including handling of different financial processing systems, protocols, privacy, security, and the like. In one embodiment a branch transaction block generator system can checkpoint some portion or all of its blockchain into a parent transaction block generator system.
