A system and method for secure and real-time converting a volatile asset into another asset in a quantum-resistant blockchain network using an Artificial Intelligence (AI) model. The method includes receiving a volatile asset conversion request and user preferences from a user through a user device, which may be user interface 400D. The AI model is then personalised by identifying patterns and correlations between the user preference, and the real-time behavioural patterns and the historic data of the user. A value of each volatile asset over time is then predicted using the personalized AI model and an optimal time to convert each volatile asset based on the value predictions is determined. Each volatile asset is converted into another asset preferred by the user, at the determined optimal time and a smart contract is generated on the quantum-resistant blockchain network to secure each volatile asset's conversation into another asset. 4D

A data processing method, a data processing system, a data processing apparatus, a computer program product and an electronic device, relating to the technical field of network security. The method may comprise: verifying a business information check value in a data block (S110); when the verification has passed, broadcasting a verification result (S120); and, when the number of verification results reaches a preset number, the data block can be uploaded to the chain (S130). Thus, in the case of a failure occurring in a business execution process, the present disclosure can avoid the problems of low fault tracing efficiency and low service activation efficiency due to a non-trust relationship between management domains; that is, the characteristics of multi-node storage and tamper-proofness of block-chain technology can be used to ensure that all operations can be traced, and operation records cannot be tampered with, thereby facilitating enhancing the efficiency of failure tracing and service activation. Furthermore, the present disclosure can improve the resistance of entire networks against malicious attacks and information tampering, thereby improving trust between different management domains.

According to examples, an apparatus includes a processor and a memory on which is stored machine-readable instructions that when executed by the processor, cause the processor to scan an application programming interface (API) for a specified label in the API, in which the specified label includes a counter that increments based on an API interacting with a computing resource for a caller of the API. The processor also reads a value of a counter in the specified label and records the read value of the counter and an identifier of an entity associated with the caller of the API onto a decentralized blockchain. The computing resource usage by the entity may thus be securely recorded, such that the computing resource usage may be used for any of a number of purposes, such as invoicing, usage tracking, and/or security.

The invention relates to a computer-implemented platform for managing the leasing of real estate assets through automated tenant-landlord verification, dynamic risk scoring, and smart contract execution. Tenant and landlord accounts are established via Know Your Customer (KYC) protocols. Tenant creditworthiness scores are computed using financial, employment, and behavioral data, and matched against landlord-defined eligibility thresholds. Lease agreements are executed via blockchain-based smart contracts, ensuring immutable, enforceable records. Rental deposit requirements are dynamically calculated based on tenant risk profiles and lease conditions, and may be fulfilled either through a real-time, event-driven insurance instrument or through financing from an authorized third-party financial institution. The insurance instrument is calibrated algorithmically to reflect changing risk exposure, behavioral history, and contextual data, thereby enabling dynamic collateralization of lease obligations. The platform further comprises modules for structured damage reporting, automated maintenance escalation, dispute resolution workflows, and landlord reputation scoring. All transactional events are logged in a tamper-evident ledger. The system also supports data export and third-party integration with financial institutions, insurers, and regulatory platforms via secure APIs and analytics dashboards.

A system and method for facilitating collection of Road User Charges (RUC) using a digital currency within a Distributed Ledger Technology (DLT) network are disclosed. The system generates secure digital wallets for Road Users and Facility Owners, receives trip, position, distance, and cost data from vehicles, sensors, and facility systems, and encodes settlement logic into smart contracts. These contracts automatically execute jurisdiction-specific disbursements across blockchain, directed acyclic graph (DAG), or hashgraph frameworks, ensuring scalability and auditability without reliance on centralized tolling infrastructure. An AI Activity Module processes multi-source telemetry—including vehicle sensors, GNSS/PNT data, roadside infrastructure, and third-party traffic feeds—to detect congestion, forecast conditions, optimize routing, and dynamically adjust segment-level RUC pricing in real time. The integration of AI-driven adaptive pricing with distributed ledger settlement provides a decentralized, infrastructure-agnostic framework for secure, transparent, and verifiable road use fee collection across multiple jurisdictions, distinct from conventional tolling systems.
