This paper presents a novel user authentication framework that integrates Nano (cryptocurrency) micropayments to enhance security while simultaneously generating revenue. Traditional authentication methods often face challenges related to scalability, user convenience, and potential vulnerabilities. Our proposed system leverages blockchain technology to implement a decentralized, tamper-resistant authentication method where users validate their identities through micropayments in Nano. This approach not only strengthens security by introducing a cost factor for each authentication attempt discouraging fraudulent access but also creates a sustainable revenue model for service providers. We detail the architecture of the framework, including smart contract implementation, micropayment mechanisms, and cryptographic safeguards. Performance evaluations demonstrate the system’s efficiency, low transaction overhead, and robustness against common cyber threats such as replay and brute-force attacks. The proposed framework offers a promising pathway towards secure, user-friendly, and economically viable authentication solutions in digital ecosystems.

Global enterprises increasingly depend on cloud computing to power critical operations. However, escalating geopolitical tensions, cross-border data restrictions, and jurisdictional conflicts have exposed organizations to new forms of geopolitical risk. Geopatriation—the process of strategically redistributing workloads from global hyperscale providers to sovereign or regional clouds—offers a viable solution to mitigate these risks. This study synthesizes literature on cloud sovereignty, multi-cloud federation, and regulatory compliance to propose a conceptual framework for geopatriation. Using case-based insights from GAIA-X and sovereign AI models, the research identifies architectural enablers, compliance drivers, and risk trade-offs. The findings demonstrate that geopatriation can balance resilience, sovereignty, and scalability in a fragmented global technology landscape.
