The blockchain generation apparatus 1 includes: a parameter calculator 122 that identifies a parameter type to be used for linkage of the new block, based on block approval method data 114, and calculates a value for the identified parameter type based on transaction datasets which are related to an identifier of a generating party; a block generation condition checker 125 that determines whether the generating party is qualified to generate the new blockchain data, based on the value calculated by the parameter calculator 122; and a blockchain generator 126 that tries to generate the new blockchain by referring to the shared data when the block generation condition checker 125 determines that the generating party is qualified. An identifier of the blend pattern included in the block approval method data 114 specifies a combination of the plurality of parameter types that conflict with each other.

Systems and methods for linking physical items to virtual content. Exemplary implementations may: receive a first request to verify whether a first activation of a first item has occurred; if not, transmit a notification in reply to the first request; receive, from a first user, a second request to effectuate the first activation of the first item and to make particular virtual content accessible to the first user; modify state of a smart contract on a decentralized database such that subsequent requests confirm the first activation has occurred; establish a link between the first item and the first user such that the particular virtual content is accessible to the first user; and responsive to the particular virtual content being accessible to the first user, transmit a second notification in reply to the second request.

A cryptographic blockchain computer network digital cryptocurrency loan system that rewards both the loan holder and the loan paying network users with system utility fund tokens for each loan payment made. System utility fund tokens entitle the system users to receive dividend distributions of passive income from a system digital cryptocurrency investment fund.

Cryptocurrencies may be used within the current Four Party Model to settle transactions between a merchant and a consumer who may use or accept fiat and/or cryptocurrency. An intermediary wallet entity may assume the risk of cryptocurrency transactions. For example, a fiat-fiat transaction may follow the usual settlement process of the Four Party Model. In a crypto-crypto transaction, settlement may occur in real time. But in a fiat merchant/crypto customer transaction, settlement may be made from the customer's crypto wallet to an intermediary wallet. Fiat settlement would then occur between the intermediary and merchant following the Four Party Model. In a crypto merchant/fiat customer transaction, a transfer may be made from the intermediary wallet to the merchant's crypto wallet. Fiat settlement between the customer's bank (issuer) and intermediary can happen in the usual settlement process.

A server system of an embodiment for transaction processing includes a virtual point-of-sale server to register data of a customer transaction based on data received from a first terminal operated by the customer in a selling area and a management server. The management server generates a machine-readable code including information for acquiring the transaction data and an electronic settlement method. The management server transmits the machine-readable code to the first terminal upon receiving a checkout instruction. Upon receiving information for acquiring the transaction data from a second terminal, the management server acquires the transaction data from the virtual point-of-sale server, and processes an electronic payment if the information regarding the electronic settlement method is received from the second terminal.

Arrangements for providing multi-party exchange functions are provided. In some aspects, a request for exchange may be received by a computing platform. The request for exchange may include identification of parties involved in the exchange, identification of goods, services, property, or the like, involved in the exchange, and the like. In some examples, the computing platform may determine a value of property, goods, or services associated with the exchange. The computing platform may request additional exchange data from one or more other parties. For instance, data associated with the exchange and another party to the exchange may be requested and received. In some examples, unique exchange identifiers may be generated linking each party to the exchange to the goods, services or property being exchange, a value, or the like. An indication of acceptance may be received and one or more exchange processing functions may be executed.

A system is provided for controlling privacy in an exchange of an asset. The system receives an offer query of an offeror that includes an offeror reveal condition, an asset identifier of the asset, and offeror terms of exchange. The system accesses an offeree reveal condition and offeree terms of exchange for the asset. The system determines whether the offeror reveal condition and the offeree reveal condition are satisfied and determines whether the offeror terms of exchange and the offeree terms of exchange are satisfied. When the offeror reveal condition, the offeree reveal condition, the offeror terms of exchange, and the offeree terms of exchange are satisfied, the system reveals the offeror to the offeree and the offeree to the offeror.

A system and method for pay-to-print printing allows a pay-to-print user to pay from any source currency to target currency through the use of a cryptocurrency service. A user selects a job to be performed on an MFP, and a job cost is generated and displayed. The MFP generates and displays a barcode on its touchscreen. The user scans the barcode and their smartphone is directed to a payment service portal, such as Google Pay or Apple Pay. The user directs payment to a crypto currency sever, along with payment target and target currency for the job. The cryptocurrency server converts payment to its cryptocurrency, and then to the target currency, and relays the target currency to target. The MFP completes the job once payment has been made.

A shared ledger operated by a group of network participants according to a set of consensus rules manages and resolves subrogation claims between a clamant and a defendant with arbitration. Evidence regarding the value of the subrogation claim is sent to the shared ledger by the parties to the subrogation claim, such as sending data to a smart contract deployed on the shared ledger. The parties to the claim may request arbitration, especially after attempts to settle the claim on-chain between the two parties have failed. An arbitrator may request evidence from the parties and/or request responses from the parties to accept damages calculations and/or settlement offers. Once the claim is resolved, the arbitrator may release funds on the chain to the prevailing party or may accept confirmation that any payments have been made between the parties off-chain.
