A settlement device includes an application reception unit that associates and stores a user ID for specifying a user and application information indicating an application to grant a privilege at the time of purchase of a target commodity in a storage unit when the user ID and the application information are acquired, a token generation unit that generates a settlement token and transmits the settlement token to a user terminal when a request for acquiring the user ID and a settlement code is received from a user terminal, a settlement information reception unit that is configured to receive the settlement information used to perform settlement of commodities, the settlement token, and privilege target commodity information for specifying a commodity which is a privilege target from a store terminal that is configured to read the settlement code according to the settlement token, and a privilege granting unit that is configured to grant the privilege corresponding to application information to the user when the application information associated with the user ID corresponding to the received settlement token corresponds to the received privilege target commodity information.

Provided is a method for distributed payment processing using a centralized payment processing platform. The method includes creating, using an application, an account associated with the centralized payment processing platform; creating, using the application, a virtual payment card associated with the account; receiving a selection of a balance for the virtual payment card within a limit of the account; receiving a selection of a recipient for the virtual payment card; generating a token associated with the virtual payment card; and transferring the token to the recipient. The payments made with the virtual payment card are processed by the centralized payment processing platform.

A system for crypto token linked assets in at least one of a game, a fantasy sport, and a wagering opportunity, the system including a token server storing at least one transaction of at least one licensor crypto token over a network, the token server being programmed to create proof of ownership for at least one of a unique digital asset and a unique physical asset of at least one licensor, analyze the at least one transaction, and associate the at least one licensor to the at least one licensor crypto token, at least one licensor apparatus being programmed to generate and distribute the at least one licensor crypto token, and send the at least one licensor crypto token to the token server, and at least one licensee apparatus being programmed to request use of the at least one licensor crypto token on the token server, and obtain a license to use the at least one licensor crypto token in response to completing the at least one transaction.

Methods and systems are presented for providing a framework for facilitating multi-party computation within a sharding environment. After a blockchain is divided into multiple shard chains, a multi-party computation system obtains attributes associated with a first shard chain. The attributes may represent characteristics of the first shard chain, characteristics of transactions recorded in the first shard chain, and characteristics of the computer nodes configured to manage the first shard chain. Based on the attributes, the multi-party computation system determines a multi-party computation scheme that specifies a minimum threshold number of nodes required to participate in a transaction validation process and at least one required node required to participate in the transaction validation process for the first shard chain. The multi-party computation system configures the computer nodes configured to manage the first shard chain to perform the transaction validation process according to the multi-party computation scheme.

The present disclosure provides a system constructed by connecting a mobile terminal and a service providing device, and a service providing method, wherein the service providing device and the mobile terminal are directly connected via an interface of the mobile terminal; the service providing device provides a service independently or through collaboration between the service providing device and various parties such as the mobile terminal and/or the background server based on the service information parsed and extracted the code information, identification information of any one or more parties among the user, the first mobile terminal, and the service providing device, and/or information bound to the identification information. Through active code scanning or passive code scanning or a combination of the two, the present disclosure may conveniently and quickly implement sensing access and effectively enhance security for operations such as mobile payment, etc.

Method of certification including receiving user data at a device of a certifying entity. The method includes generating a salt that is unique. The method includes hashing the data combined with the salt to create a generated hashed data. The method includes generating a certification record based on signing the generated hashed data using a private key of the certifying entity to create a signed certification of the data. The method includes hashing the certification record. The method includes transmitting the hashed certification record to a blockchain for storing. The method includes receiving a certification tx-ID of the hashed certification record. The method includes generating a certification data block including the certification record and the certification tx-ID. The method includes storing the certification data block to a side chain.

A payment method by a processing server to process payment that is independently performed between a user equipment and a payment channel server is provided. The method includes: generating, by the processing server, a payment order bound to a merchant order generated by a merchant device by determining a corresponding item ID, of a service and/or a product for purchase, that is registered with the payment channel server, the merchant order corresponding to the service and/or the product provided by the merchant device; obtaining, by the processing server, a payment voucher corresponding to the payment order; matching, by the processing server, based on the payment voucher, the merchant order bound to the payment order; and transmitting, by the processing server to the merchant device, based on the matched merchant order, a service/product providing notification for providing the service and/or the product to the user equipment.
