    A centrality analysis of the Lightning Network
    (2023) Zabka, Philipp; Förster, Klaus-T.; Decker, Christian; Schmid, Stefan
    Blockchain technology has a huge impact on our digital society by enabling a more decentralized economy and policy making. This decentralization is also pivotal in payment Payment channel networks (PCNs), including the Lightning Network, have emerged as a promising solution to the scalability challenges that many blockchain-based cryptocurrencies, like Bitcoin, grapple with. These PCNs, while innovative, also inherit the rigorous dependability demands of the blockchain. A pivotal aspect of this dependability is the need for a high degree of decentralization, essential for mitigating liquidity bottlenecks and on-path attacks.

    COVID-19 and the Internet: Lessons Learned
    (Emerald Publishing Limited, 2023) Stocker, Volker; Lehr, William; Smaragdakis, Georgios; Whalley, Jason; Stocker, Volker; Lehr, William
    The COVID-19 pandemic has disrupted the ‘real’ world and substantially impacted the virtual world and thus the Internet ecosystem. It has caused a significant exogenous shock that offers a wealth of natural experiments and produced new data about broadband, clouds, and the Internet in times of crisis. In this chapter, we characterise and evaluate the ­evolving impact of the global COVID-19 crisis on traffic patterns and loads and the impact of those on Internet performance from multiple perspectives. While we place a particular focus on deriving insights into how we can better respond to crises and better plan for the post-COVID-19 ‘new nor- mal’, we analyse the impact on and the responses by different actors of the Internet ecosystem across different jurisdictions. With a focus on the USA and Europe, we examine the responses of both public and private actors, with the latter including content and cloud providers, content delivery networks, and Internet service providers (ISPs). This chapter makes two contributions: first, we derive lessons learned for a future post- COVID-19 world to inform non-networking spheres and policy-making; second, the insights gained assist the networking community in better planning for the future.

    EU Cyber Resilience Act: Socio-Technical and Research Challenges (Dagstuhl Seminar 24112)
    (2024) Dalla Preda, Mila; Egelman, Serge; Mandalari, Anna Maria; Stocker, Volker; Tapiador, Juan; Vallina-Rodriguez, Narseo
    This report documents the program and the outcomes of Dagstuhl Seminar "EU Cyber Resilience Act: Socio-Technical and Research Challenges" (24112). This timely seminar brought together experts in computer science, tech policy, and economics, as well as industry stakeholders, national agencies, and regulators to identify new research challenges posed by the EU Cyber Resilience Act (CRA), a new EU regulation that aims to set essential cybersecurity requirements for digital products to be permissible in the EU market. The seminar focused on analyzing the proposed text and standards for identifying obstacles in standardization, developer practices, user awareness, and software analysis methods for easing adoption, certification, and enforcement. Seminar participants noted the complexity of designing meaningful cybersecurity regulations and of aligning regulatory requirements with technological advancements, market trends, and vendor incentives, referencing past challenges with GDPR and COPPA adoption and compliance. The seminar also emphasized the importance of regulators, marketplaces, and both mobile and IoT platforms in eliminating malicious and deceptive actors from the market, and promoting transparent security practices from vendors and their software supply chain. The seminar showed the need for multi-disciplinary and collaborative efforts to support the CRA’s successful implementation and enhance cybersecurity across the EU.

    Measuring Mobile Broadband: Challenges and Implications for Policymaking
    (2023) Frías, Zoraida; Lehr, William; Stocker, Volker; Mendo, Luis
    Mobile broadband networks constitute essential infrastructure to enable a wide range of innovative services and use cases anticipated for our digital economy future. Measuring performance is essential in many ways. First, to allow service providers to manage and develop their networks. Second, for the efficient operation of markets, and third, for evidence-based policymaking. In the rapidly evolving digital economy, capabilities for collecting more fine-grained measurements and analytics that deliver insights to enable real-time network management and localized control are expanding. As the fundamental methods used to collect measurement data are changing, the ecosystem of stakeholders with strategic interests in mobile measurement is growing and becoming more complex, posing challenges and opportunities for policymakers. Against the background of this growing complexity, this paper aims to discuss some basic features of a capable and reliable measurement ecosystem for mobile broadband. We document how the mobile broadband measurement ecosystem has changed and discuss its implications on a number of important broadband policy issues.

    Next-generation networks: Necessity of edge sharing
    (2023) Lehr, William; Stocker, Volker
