A data processing method based on a blockchain includes: receiving, by a first node device associated with a first blockchain, a cross-chain transaction request sent by a service terminal, invoking an on-chain service verification contract in the cross-chain transaction protocol, to verify whether the target cross-chain service is legal according to the service description information, to obtain a service verification result; invoking, in response to the service verification result indicating that the target cross-chain service is legal, an on-chain service execution contract in the cross-chain transaction protocol to execute the target cross-chain service, to obtain cross-chain transaction data; and sending the cross-chain transaction data to N cross-chain relay devices associated with the cross-chain transaction protocol.

A fully decentralized, audit-resilient sovereign ecosystem (BEI24HWS) empowering every individual, household, industry, and region to truly own, govern, mint and inherit their time, identity, and digital resourceswithout reliance on traditional DNS registrars, centralized identity providers, or recurring renewal fees. The system is built upon three Sovereignty Pillars (Time, Identity, Resource) and seventeen modular components, and includes a turnkey Domain-to-Module mapping of all registered top-level and second-level names to demonstrate immediate, fee-free deployment across 365 industries and 82 billion global nodes.

This invention is a money convertible to agricultural products and a system to construct it. The agricultural products are stored in a storage facility, and their quantity and quality are controlled using a computer. Based on the storage data of the agricultural products, the money is issued and circulated. The amount of the agricultural products in storage always matches the amount of the money issued, which is controlled by computer. Transactions of the money or the conversion of the money to the agricultural products are matched by the computer and network. In addition, provide a system in which the quality of agricultural products deteriorates and depreciates over time, which is reflected in the money convertible to agricultural products, and in which the money depreciates, and/or in which the money has a time limit on its use.

Provided is a device supporting financial services, and an integrated system that incorporates technologies such as QR codes, blockchain, distributed finance (DeFi), non-fungible tokens (NFT), and metaverse into financial services. Furthermore, the present disclosure relates to a method and a device for providing blockchain-based financial services and, more particularly, to a method and a device for providing services of making a payment or exchanging money through blockchain-based cryptocurrency that is performed in real time without a delay in processing time. Further, the present invention relates to: an ATM device that determines forgery/falsification of an ID card in an account opening process and authenticates the identity of an ID card holder by comparing the face of the ID card holder with the face of a photo of the ID card; and an operating method therefor. Moreover, the present disclosure relates to an electronic access management system using QR codes.

Systems, methods, devices, and non-transitory, computer-readable storage media are disclosed for execution of an order including a first portion and a second portion. A trading computer system includes a routing system and a processor configured to: determine that a leg of the first type is satisfied at a first computer network destination and a leg of the second type is satisfied at a second computer network destination; transmit a second electronic message to the first computer network destination and a third electronic message to the second computer network destination; receive a confirmation electronic message indicating that the leg of the first type and the leg of the second type were executed substantially simultaneously; generate an execution report that indicates that the leg of the first type and the leg of the second type were substantially executed simultaneously; and transmit the execution report to a portable electronic device.

The technology disclosed describes a Quantum Utility Exchange (QUE) framework for managing and trading Quantum Utility Exchange Traded Resources (QU-ETRs). Providers define quantum resource packages (with time windows, usage limits, and resource specifications) and list them in a Recorded Database. Entities granted usage rights can trade these packages on the QUE through buy, sell, swap, or bid transactions, with all ownership transfers recorded and expired/consumed packages delisted. A Pending Database supports offers to buy or sell, searchable with AI/ML tools. The exchange uses secure blockchain-based communications, encrypted private tunnels, and verification processes to ensure integrity. Interfaces for providers and consumers enable package submission, searching, bidding, and downloading through a networked computer system. QU-ETRs can be traded under flexible contract types (buy now-use now/later or swaps), with transaction, validation, and alert mechanisms built into the system. Overall, the method establishes a secure, structured marketplace for allocating and exchanging quantum computing resources.

A network-based computing system can implement a transaction service in which digital wallets of client transaction entities are dynamically monitored to maintain a balance within a liquidity tranche unique to each transaction entity. The computing system can further execute a smart liquidity model that parses transaction requests into smaller clips and execution timing intervals such that risk of transaction failure is minimized or eliminated.
