Provisioning a data rate includes receiving a digitally signed request from a requester device for data and appending the request to a distributed ledger. At least one set of digitally signed data is received from at least one data provider system. Each data set is appended to the ledger and a particular data set is selected from the at least one data set. The selected data set is provided to the requester device. A digitally signed command to provision the selected data set is received from the requester device. The command is digitally signed using the public key of the requester device. The command to provision the selected data set is appended to the ledger, causing the data provider system to be notified, and the selected data set is provisioned.

Network provisioning systems and methods

Disclosed is a method for providing fraud protection and transaction tracing for gift card accounts through use of a public blockchain ledger. Digital gift cards are associated with tokens which are passed between user accounts. The users do not obtain direct access to the debit codes assigned to the gift cards and are instead provided with variable authentication codes for use in merchant purchases. The variable authentication code is used by a merchant to obtain a reference to an actual debit code held by a web server. Numerous types of transactions are published to the blockchain ledger including initial purchases, reserving/claiming of debit codes, transfers of tokens between accounts, and depleting of gift card value associated with a token. Transactions published to the blockchain occur substantially simultaneously with a merchant purchase such that users may look up gift card values at any time to be assured each gift card is valid.

System and method for establishing a public ledger for gift card transactions

Disclosed herein are certain embodiments of systems and methods for standardizing a plurality of digital wallet credits, into one digital wallet system. Expenditures of merchant issued credit stored in digital wallets are supported by tokenization of assets. Assets are encoded and represented by currencies tracked on public ledgers. Data is mined from the public ledger, decoded, and presented to users with a unified interface which allows users to view balances at any time of all digital wallets in their possession.

Systems and methods for securing digital gift cards with a public ledger

A system and methods are provided for operating and building graphically XML processing programs, guiding the user in development of the program, preventing and detecting development errors as the program is being designed, ensuring that the program is valid, i.e. satisfies required input and output constraints at all times, i.e. from the time it is developed to when it is deployed in a production environment, ensuring the automated change management if the internal logic of the Web service, or data sources called by the service or the schema that underlies the Web service are modified. The system includes a graphical XML Programming system where XML processing programs are built and represented in a graphical fashion, a real-time metadata computation and visualization method for each selected execution point in the visual program that provides guided programming, error prevention and detection, and change impact analysis and change management, and, an automated execution path exploration method that enables overall program validation and error identification. The system and methods allow a user to reduce by at least a factor of 2 the costs of development and maintenance of reliable XML processing programs such as Web Services.
