Abstract: A computer-implemented method (100) and system (1) for controlling the performance of a smart contract. The method includes storing a contract on or in a computer-based repository. The contract is associated with a licence between a first user (U1) and a second user (U2). The method further includes receiving, over a communications network, a transaction comprising a transfer of a token from an agent (A) to the first user (U1) or the second user (U2). The transaction comprises metadata that includes an identifier indicative of a location where the contract is stored. The method further includes querying a peer-to-peer distributed ledger (i.e. blockchain) to determine whether the transaction comprises at least one unspent output (UTXO). The method further includes, responsive to querying the peer-to-peer distributed ledger, determining whether to modify performance of the contract. The blockchain may be the Bitcoin blockchain.

Abstract: Self-sovereign identity systems and methods for identification documents are disclosed herein. An example method includes transmitting data obtained from a near-field communications (NFC) chip of an object to the service provider. The data can include identifying information for an owner of the object. The method can include receiving a user identity packet from the service provider that is generated by the service provider based on verification of an identity of the owner and validity of the NFC chip, storing the user identity packet on a computing device, receiving a request from a first requesting device or service for the data stored on the NFC chip of the object and transmitting the user identity packet from the computing device to the first requesting device or service instead of the data.

Abstract: Embodiments of the invention include a method of performing a payment transaction comprising receiving transaction data by a PIN pad terminal from a point-of-sale terminal, and receiving tender from a customer, by the PIN pad terminal. Tender data and the transaction data are sent to a service gateway, by the PIN pad terminal. The service gateway collects metadata from the tender data and the transaction data. The tender data is sent by the PIN pad terminal to the point-of-sale terminal, which sends the tender data and the transaction data to a merchant gateway for approval or denial of the tender data. The tender data sent to the POS may be encrypted. The service gateway may provide customer and merchant analytics based on the metadata, as well as perform security/fraud checks, BIN management, PIN pad management. Systems are also disclosed.

Abstract: A data broker platform may store one or more data sharing preference settings of a subscriber for the subscriber data of the subscriber in a corresponding subscriber preference record of a subscriber preference blockchain ledger. The platform may further store one more access policy settings with respect to the subscriber data in a corresponding access configuration record of an access configuration blockchain ledger. The platform may receive a data request from a computing device of a third-party entity to access a set of subscriber data of the subscriber. Accordingly, the platform may provide the computing device of the third-party entity with access to the set of subscriber data when the platform determines using records in the subscriber preference blockchain ledger and the access configuration blockchain ledger that the third-party entity is permitted to access the set of subscriber data.

Abstract: Healthcare transaction validation systems and methods are presented. Healthcare transactions associated with a stakeholder are compiled into a chain of healthcare transaction blocks. The chain can be considered a chronicle of person's healthcare path through life. When a transaction is conducted, the corresponding healthcare parameters (e.g., inputs, outputs, clinical evidence, outcomes, etc.) are sent to one or more validation devices. The devices establish a validity of the transaction and generate a new block via a proof-of-work principle. Once the new block has been calculated it can be appended to the stakeholder's health care blockchain.

Abstract: Systems and methods for determining and executing complex multi-route transfers of digital assets are described. A multi-route transfer of a source asset for a destination asset may be determined by analyzing a graph representing a plurality of assets and exchanges to determine a plurality of unique transfer paths. A transfer path may reflect a direct transfer in which the source asset is swapped for the destination asset, or it may reflect a series of intermediate transfers in which the source asset is swapped for intermediate asset(s) that are swapped for the destination asset. Dynamic programming can be used to select the transfer paths to include in the multi-route transfer, how to distribute swaps across those transfer paths, and how to distribute swaps for each transfer of a transfer path—thereby optimizing for the total amount of the destination asset received while accounting for transaction fees.

Abstract: A game reward system is described herein that pays players to play a video game. The system does this by utilizing the unused resources of the player's computing device to perform cryptographic hashes and mine one or more cryptocurrencies. The game reward system generates a jackpot based on the cryptocurrency that has been mined, allocates some amount to the system operator for profit of running the system (e.g., 10%), and divides the remaining amount among the players of enough rank as a reward. Instead of charging people to buy a game, the game maker using the game reward system can make the game free for players to play. Thus, the game reward system completely changes the business model of games, makes games more fun, and rewards players in a new way for playing games.

Abstract: This invention relates generally to methods and apparatus for providing secure services using a mobile device, and in particular for securely making transactions, such as payments, using mobile phones and smartphones.

Abstract: Described herein are systems and methods for virtualizing policy enforcement amongst participants of an overlay network. In some embodiments, each of the participants may maintain a separate blockchain network. The overlay network may receive smart contracts or other policy documents that include information on interactions with a particular participant or between participants. A controller, which may be implemented on any node of the overlay network, may then extract an interaction algorithm from that smart contract that may be stored in policy data to be used in completing transactions between two participants of the overlay network. In some embodiments, the policy data may include cost data which may be used to determine how two entities may interact.

Abstract: A computer can monitor network traffic on a blockchain computing network. The computer can determine a current level of network congestion on the blockchain computing network. The computer can execute a first machine learning model that predicts a timeseries of future transaction costs based on historical data and the current level network congestion level of the blockchain computing network. The computer can also execute a second machine learning model to predict a timeseries of future transaction sizes and UTXO types for the distributed ledger-based account based on historical transaction data. The computer can select one or more UTXOs to use to complete the transaction of the transaction request. The computer can append a block instance containing an identification of the selected one or more UTXOs to the blockchain to complete the transaction.

Abstract: A decentralized hybrid system for collecting, storing, and managing sensitive data, such as medical record data. Data is stored as multiple atomic records in a centralized database. A non-fungible token (NFT) is associated with each data record and assigned to a cryptographic wallet of a party owning the data in the data record on a blockchain ledger. A user key based on the wallet is stored in a centralized user database to identify the data owner to the system. Ownership tokens are granted for each data record and distributed to parties have an ownership interest in proceeds from the sale of data. When data is purchased, the proceeds are distributed, pro rata, based on the ownership tokens.
