A computer-implemented method of operating an electronic draw system, the method comprising: obtaining a bit sequence in one or more blocks of one or more different blockchains; generating a seed value based on the bit sequence in the one or more blocks of the one or more different blockchains; applying a random number generator algorithm to calculate a sequence of random numbers using the seed value as input; and converting the sequence of random numbers to an electronic drawing output of the electronic draw system.

Method and system of performing transactions with a payment card in a managed integrated payment environment comprising an integrated circuit are disclosed comprising interacting with an integrated circuit on a received payment card to obtain card data by a payment terminal and determining whether full online transaction processing of the card data is required. If full online transaction processing of the card data is required, the card data is sent to a point-of-sale terminal, which sends the card data and a transaction total for the transaction to a merchant gateway, which obtains approval or denial of the transaction. The approval or denial is provided to the PIN pad by the merchant gateway via the point-of-service terminal. The PIN pad also receives transaction data and sends the transaction data and card data to a services processor to collect metadata, perform fraud and security checks, and/or encrypt the card data.

The instant disclosure illustrates how the privacy and security of activities occurring on distributed ledger-based networks (DLNs) can be enhanced with the use of zero-knowledge proofs (ZKPs) that can be used to verify the validity of at least some aspects of the activities without private information related to the activities necessarily being revealed publicly. Methods and systems that are directed at facilitating the tracking and recovery of assets stolen on ZKP-enabled DLNs while preserving the confidentiality of the tokens are presented herein.

An integration system for a system of platforms includes an orchestration platform, a blockchain transactional platform, a digital transactional platform, a merchant system, a user trust platform, and one or more user devices connected to each other and a distributed ledger and/or a secondary mesh network via one or more networks. The blockchain transactional platform performs accesses and performs actions on the distributed ledger and/or the secondary mesh network. The digital transactional platform maintains transactional data indicative of an amount of first-domain value correlated to a user. The blockchain transactional platform maintains blockchain transactional data indicative of an amount of second-domain value correlated to the user. The orchestration platform manages data exchange, synthesis, fusion, analysis, and transformation between the components of the system, including the orchestration of credit terms using currency balances.

The present invention relates to an electronic voting system and an electronic voting method. The system for electronic voting includes an operation computer including at least one processor and a memory coupled to the processor, wherein the processor causes the system to: perform user authentication of voting participants who wish to participate in the online electronic voting; anonymize information of the voting participants whose the user authentication has been completed; give unique identification information to each of the voting participants who have completed anonymization process; and collect the voting information that the electronic voting has been conducted using the unique identification information given to the voting participants, and count the collected voting information as voting results.

The present disclosure discloses an information processing method, device, system and computer-readable storage medium, and relates to the field of information technology. The information processing method includes: determining a second user associated with a first user from users corresponding to distribution tasks of a distributor, wherein a state of goods of the second user is Shipped; generating reconsignment information to be provided to the first user, wherein the reconsignment information comprises information of the first user and goods information of the second user; generating distribution task information to be provided to the first user in response to the first user acquiring the reconsignment information and sending a confirmation of the reconsignment information; and changing the state of goods of the second user in the distribution task of the distributor to Delivered after acquiring a confirmation of completion of reconsignment sent by the second user.

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 for assigning value to a digital asset is disclosed. In some embodiments, the system is configured to link the monetary valuation for a digital asset to a sport team's performance. In some embodiments, the monetary valuation for a digital asset associated with a sport team can increase or decrease based on historical performance or live performance. In some embodiments, the system includes a dashboard that displays various sport teams and the value of associated digital assets. In some embodiments, the system includes functionality that allows a user to buy, sell, and/or trade digital assets associated with a sports team. In some embodiments, the system includes a digital wallet configured to store the digital asset and/or a crypto key that enables access to the digital asset on a blockchain. In some embodiments, the digital asset is a digital token or a digital coin.

System and method are described for creating and validating identities across multiple blockchains. According to an embodiment, a system uses decentralized resources to receive an enrollment request comprising entity information to create a multi-chain identity of an entity and create an account with a global identifier for the entity and one or more decentralized identities (DIDs), each associated with a cryptographic blockchain of a set of supported cryptographic blockchains. The system maintains a mapping of the global identifier and the one or more DIDs created, share the global identifier and the one or more decentralized identities in a digital wallet associated with the entity. In an embodiment, the digital wallet is implemented as an application to be run on a computing device associated with the entity. The digital wallet stores the global identifier, the one or more decentralized identities, and corresponding cryptographic keypairs associated with each of the one or more DIDs.
