Making CRDTs Byzantine fault tolerant
Proceedings of the 9th Workshop on Principles and Practice of Consistency for Distributed Data, 2022 It is often claimed that Conflict-free Replicated Data Types (CRDTs) ensure consistency of replicated data in peer-to-peer systems. However, peer-to-peer systems usually consist of untrusted nodes that may deviate from the specified protocol (i.e. exhibit Byzantine faults), and most existing CRDT algorithms cannot guarantee consistency in the presence ...

Stall‐Free Asynchronous State Repartitioning With a Proactive Workload Tracking Window
Concurrency and Computation: Practice and Experience, Volume 38, Issue 3, February 2026.ABSTRACT High‐throughput stateful applications rely on dynamic data repartitioning to adapt to changing workloads, but this process presents significant challenges. This paper provides a detailed analysis of such challenges, drilling down into the tradeoffs between adaptation, computational overhead, and service availability. We identify that a primary

Scaling Byzantine Fault Tolerance
, 2019 Online services are becoming more and more ubiquitous and keep growing in scale. At the same time, they are required to be highly available, secure, energy-efficient, and to achieve high performance. To ensure these (and many other) properties, replication and distribution of these services becomes inevitable.
