Systems, methods, and computer-readable storage media utilized in math-based currency (MBC) exchange utilizing MBC transaction guarantees. One method includes receiving, from a merchant point of sale (POS) terminal, a payment reimbursement request comprising a guarantee identifier associated with an MBC transfer. The method further includes determining, utilizing the guarantee identifier, transaction information. The method further includes determining, utilizing the transaction information, the guarantee identifier is associated with a failed transaction based on accessing and analyzing a plurality of disputed transactions on an MBC blockchain. The method further includes, in response to identifying the failed transaction, initiating an MBC payment from the financial computing system to an MBC address of a merchant. The method further includes providing, to the merchant POS terminal, a payment confirmation.

A system is provided for performing transaction mixing between a plurality of users on a blockchain. The system is configured to carry out the steps of: selecting an initiator node to calculate a deterministic hash function using a chosen random number; distribute the deterministic hash function to a plurality of users on the blockchain; choose an amount of time each user is given to construct a payment channel, retrieve the random number, and submit an execution transaction to a blockchain network; choose a second time for when a payment to a user is submitted to the blockchain network; and establish a one-way payment channel between every pair of users in an ordered set of the plurality of users to establish a transaction chain linking all users.

In a method and computer system adapted for performing digital asset donation transactions for nonprofit organizations (NPOs), at least one of one or more computing devices ingests digital donation assets from one or more donors intended for a NPO, and then tokenizes the ingested digital donation assets using stablecoin to provide tokenized assets. The tokenized assets are then processed for transfer via ACH to the NPO.

An information processing method is provided and includes: acquiring a patient ID for identifying a patient, the patient's attributes, and the patient's answers to medical questions; acquiring a doctor ID for identifying a doctor; transmitting the patient ID, the attributes, and the answers of the patient to a doctor terminal device corresponding to the acquired doctor ID; receiving an input of medical examination data for the patient through the doctor terminal device on which the patient ID, the attributes, and the answers of the patient are displayed; receiving a request to transmit medical data including the patient's attributes and answers and the input medical examination data; outputting a hash value of the medical data to a blockchain system; receiving a request for disclosure of the medical data; and outputting the medical data to a researcher terminal device when the patient's approval for the disclosure request from the researcher is obtained.

A method, system, apparatus, and computer program product for accessing and communicating data between accounts, including incentives for their use. Consumers, businesses, creditors, and agencies may be allowed to create and manage a centralized collections account. Consumers may be able to pay, negotiate, and manage their past due debt accounts within the centralized collections account. Businesses, creditors, and agencies may be able to negotiate with customers, manage clients and sub clients, and set legal terms and conditions within the centralized collections account. Rewards may be earned for negotiating and paying off a collections account or assisting others in these actions. Businesses, creditors, and agencies may be able to electronically communicate amongst themselves and with consumers, potentially reducing postal and telephone expenses.

Payment methods and systems for processing a payment using a Central Bank Digital Currency (CBDC) without a double payment in an offline situation (e.g., in a situation in which a terminal of a user is unable to be connected) to a server through a network may be provided.

An Electronic Health Record (EHR) data blockchain system configured to allow multiple entities (e.g., pharmacy industry entities and healthcare providers that can act as data, service, product and service providers, and consumers) to connect to an EHR patient transaction blockchain (e.g., EHR-DATA-BC) and an EHR Data Patient Portal (e.g., EHR-Data-PP) to provide a centralized location for messages and subsequent edits to ensure uniform message data is presented. The EHR data blockchain system can include an EHR Data API, an EHR patient transaction blockchain API, and an EHR patient transaction blockchain. The EHR data blockchain system can provide workflow on the blockchain that can utilize smart contracts to define workflow processes, expected outcomes, and financial costs. When a prescription transaction is complete, it will result in the settlement of each of the smart contracts that were added to the prescription workflow.

Systems, methods, and computer-readable media disclosed herein relate to reducing computation and computing resources for certain blockchain related transactions. Specifically, software algorithms and architecture allow some transactions to avoid the need for recordation on a blockchain, which can be computationally expensive both for a requesting device and for various nodes on the blockchain. Thus, a computer system may receive indications of incoming transactions transferring digital assets to particular user accounts, and in response to requests from user accounts, the computer system facilitates one or more internal transactions between those accounts. In response to a request from a particular internal user account, the computer system may perform an outgoing transaction transferring one or more digital assets to an external user account from one or more internal user accounts. The incoming transactions and outgoing transaction are recorded on the blockchain, but the internal transactions are recorded on an internal ledger rather than the blockchain, saving computational power and improving computer operations.

A method for pooling and retrieving block rewards in a reward pool including an operator node and a set of member nodes in a distributed network extending a proof-of-space-based blockchain includes: submitting a transaction configured to generate a singleton in a set of singletons, the singleton including: an outer puzzle hash linking the singleton to a singleton puzzle hash; and an inner puzzle hash defining a pool address associated with the reward pool; generating a block including a proof-of-space and a block reward allocated to the singleton puzzle hash; detecting the block reward allocated to the singleton puzzle hash; identifying the singleton linked to the singleton puzzle hash; and submitting a transaction configured to: remove the singleton from the set of singletons; and transfer the block reward from the singleton puzzle hash to the pool address.

A software development kit (SDK) allow a user to be able purchase a gift card through an offer wall and, in return, the user can receive a reward in game currency, such as coins, diamonds, tokens or the like. Most mobile apps offer their users a way to purchase coins, diamonds, tokens, or the like, which is also known as an in-app purchase. The gift card offer wall can allow the game player to purchase a gift card from a choice of vendors, and, in return, obtain the desired game currency as a bonus. The system can include three elementsthe SDK for various platforms, an electronic wallet application and servers that communicate with both the SDK and the wallet application. The SDK is something that the app publisher can add to their own mobile application that will launch the gift card offer wall for the user.
