1. A computer-implemented method of facilitating a value exchange, the method comprising:

  • establishing, between a value exchange system and a mobile device associated with a first entity, a communication connection;

    performing, by the value exchange system with the mobile device using the communication connection, a synchronization process that includes;

    receiving a request from the mobile device;

    determining that the received request is a value exchange request that was initiated by the first entity using the mobile device while the mobile device was disconnected from the value exchange system;

    authenticating, by the value exchange system, the value exchange request using at least one transaction certificate that is included with the value exchange request;

    determining, from the value exchange request, an identifier that corresponds to a second entity and that was provided in the value exchange request while the mobile device was disconnected from the value exchange system;

    determining, from the value exchange request, a value to be exchanged between the first entity and the second entity that was provided in the value exchange request while the mobile device was disconnected from the value exchange system; and

    sending, to the mobile device, updated transaction information for a previous transaction that is unrelated to the value exchange request, wherein the updated transaction information for the previous transaction was generated by the value exchange system while the mobile device was disconnected from the value exchange system and in response to a clearing of the previous transaction, and wherein the updated transaction information is configured to cause the mobile device to remove the previous transaction from a transaction log included in the mobile device;

    sending, by the value exchange system, a notification of the value exchange request to the second entity using the identifier that is associated with the second entity; and

    modifying, by the value exchange system based on the value exchange request, a first balance of a first account provided by the value exchange system and associated with the first entity.
