Exemplary systems, methods, and computer-accessible mediums can include, for example, receiving a first location of a user(s) and time information associated with that location, initiating a record for the user(s) based on the location and the time information, receiving a second location of the user(s), where the second location can be in a second bounded area, storing in record, a transaction(s) associated with the user(s) based on the second location, and automatically initiating a single payment for the transaction(s) when the user(s) leaves the first location.

Provided herein are systems, devices and methods for transferring cryptocurrency from a limited access cryptocurrency wallet. The limited access cryptocurrency wallet may create, in advance, provisional account(s) allocated for respective recipient(s) and transfer a predefined overall value of cryptocurrency from its associated account associated to the provisional account(s). The limited access cryptocurrency wallet may further generate, in advance, a plurality of signed transactions for transferring a plurality of predefined partial values of cryptocurrency from the provisional account(s) to receiving account(s) associated with the recipient(s) and transmit the plurality of signed transactions to a network connected cryptocurrency wallet. Later, in real-time, the network connected cryptocurrency wallet may transmit one or more of the plurality of signed transactions for transferring cryptocurrency from the provisional account(s) to the receiving account(s) without physically attending to the limited access cryptocurrency wallet.

Embodiments of the application provide a method, apparatus, and electronic device for implementing blockchain-based transactions. The method comprises: determining a transaction amount to be remitted from a remitter's blockchain account into a receiver's blockchain account, wherein a commitment of the remitter's balance is recorded with the remitter's blockchain account in a blockchain, a commitment of the receiver's balance is recorded with the receiver's blockchain account in the blockchain; obtaining a commitment of the transaction amount by using the homomorphic encryption algorithm according to the transaction amount; and submitting to the blockchain a transaction comprising information of the remitter's and the receiver's blockchain accounts, and the commitment of the transaction amount, for the commitment of the transaction amount to be deducted from the commitment of the remitter's balance and the commitment of the transaction amount to be added to the commitment of the receiver's balance.

A transferable value or rights token where the value or rights can be passed from entity to entity as required in a secure fashion. The value or rights passed in the tokens is held by the users in pockets directed by means of a controller device. The tokens are anonymous but the users need to be authenticated in order to gain access to their pockets. The tokens can be stored off-line and passed between users as required at which point the final receiver can go on-line to load or verify the token.

A transaction processing system may include: a plurality of leaf chains including a first leaf chain and a second leaf chain, the first leaf chain and the second leaf chain including a first leaf chain manager contract and a second leaf chain manager contract, respectively; a root chain comprising a root chain manager contract for the root chain, a first leaf chain contract for the first leaf chain, and a second leaf chain contract for the second leaf chain; and at least one relayer located between the root chain and the plurality of leaf chains, and configured to process a remittance request from the first leaf chain to the second leaf chain.

A method for a fully distributed privacy-preserving multi-lateral netting between parties is disclosed. The method comprising collecting pending transactions between at least a part of the parties, publishing a commitment of pending transactions to a bulletin board, secretly sharing de-commitments among the parties, and publishing, by each party, its determined liquidity status, to the bulletin board. Furthermore, the method comprises upon determining a failure in the publishing of any liquidity status, performing the following MPC by determining whether all pending transactions are settable maintaining positive liquidity for each party, and upon determining a failure in the determining, for each party, whether all pending transactions are nettable determining an optimized subset of transactions that are nettable without violating liquidity requirements for each party.

A computer-implemented system and method uses a processor of a device of an expiring virtual currency (EVC) wallet user. An EVC transaction is retrieved that is associated with a blockchain and addressed to an address associated with the EVC wallet. The EVC transaction comprises an expiration date for the EVCs, as part of virtual currency user rules (VCURs). If the expiration date of the EVCs has passed, the method automatically, and without user intervention, transfers the EVCs to a transferee designated in the VCURs.

A method for querying information in a visual smart card, comprising: a micro control unit receiving, by means of an input device, a query request inputted by a user (S1); the micro control unit determining information queried by a user request according to a received query request (S2); if first information, the micro control unit reading a first information record which is stored thereby, and parsing the first information record to obtain the first information, the first information being displayed by means of a display device (S3); if second information, the micro control unit sending an application selection instruction to a smart card chip, receiving an application selection response returned by the smart card chip, then sending an information record reading instruction to the smart card chip, receiving a second information record returned by the smart card chip, and parsing the second information record to obtain the second information, the second information being displayed by means of the display device (S4). A visual smart card applicable to said method overcomes the shortcomings in the existing technology wherein the assistance of other devices is required, while carrying out querying by means of operating a smart card directly facilitates a holder of a smart card understanding information in the smart card, improving the ease of use of smart cards.

An object-oriented synchronization pattern for synchronizing a mobile application and a corresponding enterprise application is provided herein. The synchronization pattern uses service invocations to convey application state differential from the mobile device to the enterprise server and object-based database synchronization for conveying application state differential from the enterprise to the mobile device. Service invocations may be conveyed in batch or individually separately and using a variety of service types.
