This tutorial examines well-known algorithms for distributed consensus problems, from classical consensus to blockchain consensus. We discuss exact algorithms that are high-level as in pseudocode and directly executable as programs at the same time, focusing on how to quickly program, configure, run, and check these algorithms as well as distributed algorithms and systems in general.
The task of training deep neural networks on a large amount of data requires a lot of resources. The solution of such a problem is often impossible to carry out on one computing device in an adequate time. distributed...

The Internet of Things (IoT) has greatly benefited the technological advances of a variety of fields, such as manufacturing and medicine, to name a few. The context surrounding these use cases is, however, often widely different from conventional Cloud computing and web applications. Cyberphysical environments present us with major concerns and constraints surrounding the resilience of systems, which often rely on critical infrastructure and important workloads to prevent major losses for businesses or even the endangerment of individuals. The supervision of these infrastructures, outside the controlled and relatively safe environment of a datacenter, is therefore one of the major considerations for modern IoT systems. In this paper, we evaluate the core concepts around this thesis and propose an architectural and conceptual approach to improve the monitoring, scalability, and orchestration of IoT systems. We leverage and integrate different solutions inspired by modern IoT practices and the cloud ecosystem to optimize both software and hardware aspects. The solution revolves around an Edge computing approach, Event-driven communication (MQTT) in the Edge, the orchestration of containerized services using Kubernetes and KubeEdge, and Device Twins for the management of physical components. Through development, experiment, and evaluation, we propose an architecture and two complementary fault-tolerance strategies to address synchronization between cloud and edge components and improve the overall resilience of the system.

The evolution of intelligent transport systems (ITS) has significantly enhanced driving experiences in vehicular ad-hoc networks (VANET), crucial for improving road safety and traffic efficiency. Despite these advancements, challenges persist. Trust management solutions often assume user legitimacy without verification. Moreover, the need for reauthentication as vehicles move between RSUs adds computational complexity. VANET is relatively vulnerable to security threats from multiple parties given its highly dynamic topology and its wireless and heterogeneous communication mode. We have expanded upon Maria et al.'s schema by specifically targeting and resolving significant shortcomings in their research. More precisely, we improve the features related to confirming the identity of users, preventing vehicles from being used without authorization, and continuously monitoring their current location in order to strengthen the security of vehicles and increase user involvement. We suggest implementing a schema that utilizes QR code verification to authenticate vehicle users, specifically targeting these difficulties. In VANETs, blockchain has been adopted with the authentication process for fog computing. The result is that there is no need for trusted authority (TA) while achieving privacy within the blockchain network and ensuring of the vehicle user authentication and the integrity of messages. Several key benefits have been achieved, such as blocking malicious entities and the potential damage they cause, enabling the revocation of malicious vehicles by conditional anonymization, as well as simplifying conflict resolution. Likewise, the proposed work was characterized by achieving an effective balance between effectiveness and complexity, protecting privacy, conditional tracking, ensuring integrity, and anonymous authentication.
The recent advancement of pretrained models shows great potential as well as challenges for privacy-preserving distributed machine learning technique called Federated Learning (FL). With the growing demands of foundat...
