Various embodiments provide management of virtual goods. In some embodiments, a gaming platform can be used to provide a secure ledger system for recording money transfer, play action, bets, analytics, gaming statistics, and the like, which are associated with virtual goods. Non-limiting examples of virtual goods comprise: characters; badges/icons; gameplay attributes; virtual money; cryptocurrencies; tokens; digital gifts; gameplay levels/add-ons; and prizes, among other examples. In some examples, gaming systems can directly interact with the distributed multi-ledger architecture for secure and transparent transactions which can also be accessed by auditors, tax authorities, partners, and/or other entities. Some examples may use private and/or public blockchains as part of the distributed multi-ledger gaming architecture. For instance, multiple distributed network nodes may be utilized to manage transaction records.

An encryption method and apparatus based on homomorphic encryption using a composition of functions. The encryption method includes generating a ciphertext by encrypting data, and bootstrapping the ciphertext by performing a modular reduction based on a composition of a function for a modulus corresponding to the ciphertext.

A management method and apparatus for a system configuration independent of a smart contract for a blockchain is provided. The method includes that: a blockchain node receives a new proposal, where the new proposal includes at least one transaction; the blockchain node determines whether a special transaction exists in the at least one transaction, where the special transaction is used for storing system configuration content without service logic; the blockchain node verifies the special transaction according to a preset verification rule to obtain a verification result in response to determining that the special transaction exists in the at least one transaction; and the blockchain node performs, in response to the verification result indicating that the special transaction passes verification, update management on a current system configuration according to the system configuration content.

The present invention relates to a graphic-blockchain-orientated sharding storage apparatus, at least comprising a first sharding module and a second sharding module, wherein the first sharding module shards nodes having different resource capacity levels based on ledger data organized using a DAG structure, and the second sharding module assigns transactions to the shards matching with execution difficulty levels of the transactions, so that each said transaction is processed and stored in the shard corresponding thereto. The present invention incorporates the sharding technology into a graphic blockchain to provide a graphic-blockchain-orientated sharding storage method, so as to reduce pressure in terms of data storage and transaction processing on nodes of the graphic blockchain system. In addition, nodes, transactions, and data are dynamically divided according to resource heterogeneity among nodes, so as to further enhance performance of the graphic blockchain system while achieving efficient use of resources.

The present disclosure describes transaction-enabling systems and methods. A system can include a facility including a core task including a customer relevant output and a controller. The controller may include a facility description circuit to interpret a plurality of historical facility parameter values and corresponding facility outcome values and a facility prediction circuit to operate an adaptive learning system, wherein the adaptive learning system is configured to train a facility production predictor in response to the historical facility parameter values and the corresponding outcome values. The facility description circuit also interprets a plurality of present state facility parameter values, wherein the trained facility production predictor determines a customer contact indicator in response to the plurality of present state facility parameter values and a customer notification circuit provides a notification to a customer in response.

Systems and methods for securely verifying integrity of application responses are disclosed. One example method includes receiving, from a client, an application encrypted in accordance with a fully homomorphic encryption (FHE) algorithm, generating, with a trained machine learning model associated with the FHE algorithm, a plurality of first application labels, each first application label indicating a true or false response associated with the application, inverting a randomly selected portion of the plurality of first application labels, generating a first randomly sorted list including the plurality of first application labels, transmitting the first randomly sorted list to the client, receiving a first decrypted list from the client, performing a validation of at least the first decrypted list, the validation based at least in part on the plurality of first application labels, and in response to the validation being successful, providing the client with a response to the application.

A system is provided for end-to-end electronic data encryption using an intelligent homomorphic encrypted privacy screen. In particular, the system may be configured to use homomorphic encryption on sensitive data displayed on a screen of a computing device. An augmented reality (“AR”) device may be used (e.g., a user) with the privacy screen such that the sensitive data that appears on the screen may be selectively decrypted. In this way, an authorized user may be able to view and interact with the encrypted data whereas an unauthorized user may not.

An autonomous distributed wise area network (AD-WAN) includes several nodes, where each node connects a local area network to an open wide area network, and provides tunnels over the open wide area network to other nodes in the AD-WAN so that computing resources behind each node can communicate as if they were located on a common intranet. Each node has a blockchain wallet and receives updates to a private permissioned blockchain ledger for that AD-WAN. The updates are provided by a control node. Set up, and subsequent change to the AD-WAN are commenced via a customer portal which provides order information to the control node, where the control node processes the order information and generates a blockchain update that informs the affected nodes in the AD-WAN as to what changes are to be made. As a result, the blockchain provides both control plane and order management operation of the AD-WAN.

A computer-based method is provided for managing a transaction including provision of a process intelligence engine comprising a workflow aligner and process tool box, receiving deal parameters at the process intelligence engine, defining transaction subjects, each requiring the participation of at least one network partner, where each transaction subject is a requirement for achieving the objective of the transaction, defining, for each transaction subject, a plurality of subject goals to be addressed by a network partner, and defining, for each subject goal at least one action item required for satisfying the subject goal. The subject goals are then sequenced by the workflow aligner by defining prerequisites for at least one subject goal and transaction modules are defined based on the sequencing. During execution of a deal using the method, subject goals are not made available until prerequisite subject goals have been completed.
