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.

Resumen de: US2025378511A1
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.

Resumen de: AU2024258351A1
This invention pertains to the fields of distributed ledger, cryptocurrency, and decentralized physical infrastructure network. It solves the problems of the blockchain trilemma and cryptocurrency's lack of a real-world value that is recognizable to the mainstream population. Those two problems have prevented any cryptocurrency from gaining mass adoption. The Golf Ledger is distributed across a network of computers that are installed at up to 40,000 golf courses to leverage the existing decentralization of the world's golf courses and their ownership entry barrier and therefore does not need to sacrifice scalability for decentralization and security. The Golf Token as the native cryptocurrency of the Golf Ledger network is rewarded to golf courses for their contributing more and more computing resources to make the network more scalable. Their customers can use the Golf Token to pay golfing fees and get a discount, which is an obvious real-world value.
