Abstract: A method includes initiating, by a first computing device, ownership acquisition of a good from a second computing device using a digital exchange item. The method further includes determining, by the second or a third computing device, whether a first warranty is applicable to the good. When the first warranty is applicable, the method further includes obtaining, by the second and/or the third computing device, a representation of the first warranty. The method further includes executing, by the second and/or the third computing device, the ownership acquisition of the good by the first computing device using the digital exchange item, wherein the executing includes updating a digital chain of custody of the digital exchange item. The method further includes updating, by the second and/or the third computing device, the digital chain of custody to include affiliation of the first warranty to the good and to the first computing device's user.

Abstract: A method includes obtaining, by a first computing device, a digital exchange item. The method further includes sending, to a server, a request to share the digital exchange item with a group of computing devices. The method further includes determining, by the server, whether the digital exchange item can be shared based on one or more of: an issuer agreement and exchange item rules. When the digital exchange item can be shared, the method further includes the server establishing secure custody rights for each computing device, determining haring rights regarding the digital exchange item, and generating replications of the digital exchange item. The method further includes the server uploading the replications and the sharing rights to digital wallets associated with the computing devices of the group.

Abstract: A method begins with a server in a data communication system identifying an instance for a user computing device associated with an exchange item to utilize the exchange item for acquisition of a particular item, where the particular item has an acquisition value. For the instance, the method continues with the server determining whether a quantifiable value of the exchange item compares favorably to the acquisition value, where a set of exchange item rules includes rules established by an issuing server regarding use of the exchange item with respect to the particular item. When the quantifiable value of the exchange item does not compare favorably to the acquisition value, the method continues with the server determining an alternative exchange item utilization protocol to facilitate the acquisition of the particular item and when requested, executing the alternative exchange item utilization protocol to facilitate the acquisition of the particular item.

Abstract: A method begins with storing, by an enterprise storage, an exchange item database, an agreements database, and a rules database. The method continues with an enterprise server initially validating exchange items and creating records in the exchange item database for validated exchange items, where each of the exchange items includes data regarding a quantifiable value, a serial number, and issuance information. The method continues with the enterprise server securely transferring a selected exchange item from a first computing device to a second computing device in accordance with an offer for sale of the selected exchange item and securely applying the selected exchange item to a closed loop digital transaction between two computing entities in accordance with an agreement of the agreements database. The method continues with the enterprise server securely modifying the data of the selected exchange item in accordance with an applicable set of rules from the rules database.

Abstract: A method begins with a server in a data communication system establishing an initial validity of an exchange item that includes data regarding a quantifiable value, a serial number, and issuance information, where the initial validity authenticates the exchange item and the data. The method continues with the server executing a secure custody protocol to establish that a first computing device has secure custody of the exchange item and to maintain validity of the exchange item. The method continues with the server transferring the secure custody of the exchange item from the first computing device to the server or to a second computing device. When the exchange item is in the secure custody of the server the method continues with the server modifying the data of the exchange item to produce a modified exchange item and transferring secure custody of the modified exchange item to the first computing device.

Abstract: A method begins with a server recording conditions for an exchange item. The method continues with the server determining whether a corresponding condition of the exchange item is compliant with one or more rules of an applicable set of rules. When the corresponding condition of the exchange item is compliant with the one or more rules, the method continues with the server establishing a secure communication with a computing device affiliated with a current owner to take control of the exchange item. While having control over the exchange item, the server securely modifies a quantifiable value of the exchange item based on the one or more rules to produce a modified exchange item and prevents the computing device or another computing device from accessing the exchange item. The method continues with the server releasing control of the modified exchange item to the computing device affiliated with the current owner.

Abstract: A method begins with a marketplace server authenticating value of an exchange item to produce an authenticated value of the exchange item and continues with the marketplace server obtaining control over a secure exchange item package, where the secure exchange item package includes identity of the exchange item. The method continues with the marketplace server receiving, from a buyer device, a request to purchase the exchange item and securely passing, to the buyer device, control over the secure exchange item package. For use of the exchange item, the method continues with the buyer device securely passing, to a merchant server, control over the secure exchange item package. The method continues with the merchant server executing use of the exchange item by updating the value of the exchange item, generating an updated secure exchange item package, and securely passing, to the buyer device, control over the updated secure exchange item package.

Abstract: A method begins where a processing module receives, from a seller computing device, a request to sell an exchange item and verifies information regarding the seller computing device. The method continues where the processing module verifies information regarding the exchange item and adds the exchange item to a digital exchange item marketplace. The method continues where the processing module receives, from a buyer computing device, a request to buy a selected exchange item from the digital exchange item marketplace and verifies information regarding the buyer computing device. The method continues where the processing module verifies payment information, processes payment, removes the selected exchange item from the digital exchange item marketplace, and adds the selected exchange item to a digital wallet associated with the buyer computing device.

Abstract: A machine and process for making and for using a machine. The process includes receiving, by the computer over a network, a notification of a payment comprising an amount of cryptocurrency and a first cryptocurrency address, and effectuating, by the computer, the purchase by using the amount and the cryptocurrency address from which a first public key can be derived, and applying the computer system to verifying that a digitally represented human or entity purporting to have made a purchase with cryptocurrency is entitled to obtain value for the purchase.

Abstract: A method includes receiving, by a warehouse server, flash sale data file from a retail-type server. The method further includes storing, by the warehouse server, the flash sale data file in a database that functions as a virtual warehouse of flash sales. The method further includes interpreting, by the warehouse server, the information of the flash sale data file to determine flash sale parameters. The method further includes determining, by the warehouse server, whether a computing device has customer-device data that corresponds to the flash sale parameters. The method further includes, when the computing device has the customer-device data that corresponds to the flash sale parameters, generating, by the warehouse server, a customer specific coupon regarding the flash sale. The method further includes transmitting, by the warehouse server, the customer specific coupon to the computing device.
