    Efficient Checkpointing in Byzantine Fault-Tolerant Systems
    (Tagungsband des FB-SYS Herbsttreffens 2019, 2019) Eischer, Michael; Distler, Tobias
    Distributed Byzantine fault-tolerant systems require frequent checkpoints of the application state to perform periodic garbage collection and enable faulty replicas to recover efficiently. State-of-the-art checkpointing approaches for replicated systems either cause significant service disruption when the application state is large, or they are unable to produce checkpoints that are verifiable across replicas. To address these problems we developed and evaluated deterministic fuzzy checkpointing, a technique to create consistent and verifiable checkpoints in parallel with request execution.

    Systems Support For Efficient State-Machine Replication
    (Tagungsband des FB-SYS Herbsttreffens 2019, 2019) Habiger, Gerhard; Hauck, Franz J.
    State-Machine Replication (SMR) is a well known approach for the deployment of highly fault-tolerant services. Recent research has focused on efficiency improvements, performance optimisation and novel approaches to underlying concepts of SMR, such as consensus with trusted components, dynamic weights for quorums, or parallelisation of application code. To increase adoption of SMR as a basic fault-tolerance technique, we see the need to improve the current state of the art of SMR even further, and provide four specific ways in which our research contributes to this goal. In particular, we present two approaches which make the development and deployment of SMR services both easier and more efficient, and talk about two further areas of improvement concerning internal mechanisms of common SMR architectures. The goal of this paper is to provide our current understanding of important issues of current SMR systems as well as to outline possible future solutions to them.
