To manage property records using a multi-layered hybrid distributed ledger architecture, identification information for a particular property is obtained and transmitted to at least one participant in a public distributed ledger network for a public distributed ledger layer. Ownership information for the same particular property is obtained and transmitted to at least one participant in a federated distributed ledger network for a federated distributed ledger layer. Transaction-related documents for the same particular property are obtained and transmitted to at least one participant in a private distributed ledger network for a private distributed ledger. The distributed ledger layers are different layers of a property distributed ledger each having a separate set of consensus rules for appending distributed ledger data to the respective layer. This allows for the immutable preservation of royalty terms and conditions for a property or asset using the distributed ledger.

A method for securing an interblockchain transaction includes receiving, from a first user application, a registration request including a first permissioned blockchain public key and a first permissionless blockchain public key. The method also includes performing, by the processing circuitry, receiving, from a second user application, a second registration request including a second permissioned blockchain public key and a second permissionless blockchain public key. The permissioned blockchain public keys are valid on the permissioned blockchain and the permissionless blockchain public keys are valid on the permissionless public blockchain. In addition, the method includes receiving, from the first user application, a transaction identification, the transaction identification identifying a first transfer transaction executed on the permissionless public blockchain. The transaction identification identifies the first and second permissionless blockchain public keys.

A method for securing a cryptocurrency transaction on a permissioned blockchain, which involves cryptocurrencies of a permissionless public blockchain, includes receiving a join request including a transaction identification. The transaction identification identifies an enroll transaction involving a public smart contract deployed on the permissionless public blockchain, the enroll transaction identifying a permissioned blockchain public key being valid on the permissioned blockchain and transferring a cryptocurrency balance to the public smart contract. The method further includes verifying that the enroll transaction was properly executed, crediting an account corresponding to the permissioned blockchain public key with the cryptocurrency balance, and receiving a send request identifying a second cryptocurrency balance and a second permissioned blockchain public key being valid on the permissioned blockchain. The method also includes transferring the second cryptocurrency balance from the permissioned blockchain public key to the second permissioned blockchain public key.

A secure cryptocurrency transactional system for actuating transactions involving electronic gaming machines and cryptocurrency wallets.

A system and method for payment of services, especially health care services, at fixed prices allows a user to purchase a service card that is accepted by a service provider for full payment of a service. A card manager holds funds from the sale of the card and releases the funds to a service provider when documentation that the service has been provided is received.

A computing system includes a first computing platform and a virtual exchange computing platform, where the first computing platform provides an application and a first electronic value token and the virtual exchange computing platform is communicatively coupled to the first computing platform. The virtual exchange computing platform receives the information corresponding to the first electronic value token and calculates, via API functions linking to banking as a service (BaaS) functionality processed by a valuation computing platform, a valuation of the first electronic value token. The virtual exchange computing platform causes presentation, via a network and on a first user device, a user interface screen presenting a visualization of a value of the electronic value token and comprising an input and triggers, based on a received trade input from the user interface, a virtual exchange of value involving the first electronic value token.

There are provided systems and methods for a carbon neutral blockchain protocol for resolving carbon offsetter payments for cryptocurrency transactions. A service provider, such as an online transaction processor, may provide a green wallet and network protocol that provides carbon offsetting fees and payments to carbon offsetters in order to account for carbon emissions and usage when processing cryptocurrency transactions on a blockchain network protocol. A green wallet may be provided, which allows registration of carbon offsetters and use of green addresses to cause cryptocurrency to be processed in a green transaction. A user's digital wallet may sign an initial cryptocurrency transaction and provide the fee to the green wallet. The green wallet may then resolve the cryptocurrency transaction by further signing the transaction and transmitting the fee to a digital wallet of the carbon offsetter over another cryptocurrency processing network.

Systems and methods for complex process flow approval using distributed ledgers are disclosed. The method may include generating a process initiation message based on input from a second service provider or a user. The method may include recording the process initiation message on a first distributed ledger. The method may include monitoring the first distributed ledger for an indication of an approval event. The method may include generating a settlement event based on the indication of the approval event. The method may include recording the settlement event on the first distributed ledger. The method may include communicating a settlement event message to a second distributed ledger. The method may include generating a virtual payment instrument associated with the settlement event message, the indication of the approval event, and the process initiation message.

A computer-based system collects data associated with a user activity. The data is transmitted from an app running on a computing device with a user account authenticated by the computer-based system. A carbon footprint of the user activity is calculated based on the data associated with the user activity. The system calculates a proof of environmental impact in response to a function of the carbon footprint and a baseline value. An amount of cryptocurrency is generated based on the proof of environmental impact by writing a transaction for the amount of cryptocurrency to a blockchain in response to proof of environmental impact. The amount of cryptocurrency is assigned to the user account authenticated with the computer-based system.

Particular embodiments determine, at least in part by a computing device of a payment service, to associate a data object with a user account that is associated with a stored balance managed by the payment service. The computing device associates an amount of the data object with a distinct stored balance associated with the user account. The distinct stored balance is associated with a condition of use. The computing device monitors transaction data associated with users of the payment service. The computing device identifies, from the transaction data, a transaction associated with an identifier associated with the user account. Based on a determination that the transaction satisfies the condition of use, processing payment for the transaction using at least a portion of the distinct stored balance prior to using the stored balance.
