Scalable byzantine fault-tolerant storage

, 2011
—Byzantine fault-tolerance is costly, both in terms of increased latency and limited scalability. Most recent contribu-tions in the area have addressed the latency aspect, leaving the throughput scalability problem largely untouched.

Reducing the Energy Consumption in Fault-Tolerant Distributed Embedded Systems with Time-Constraints

, 2007
In this paper we address the problem of reducing the energy consumption in distributed embedded systems associated with time-constraints and equipped with fault-tolerant techniques. A greedy heuristic is presented to reduce the energy during task mapping

Hashgraph Over the Edge: Achieving Byzantine Fault Tolerance in Decentralized P2P Frameworks

IEEE Access
This paper explores the integration of the Hashgraph consensus protocol into two widely used peer-to-peer (P2P) communication frameworks: Secure Scuttlebutt (SSB) and libp2p. SSB operates within a local-first architecture, prioritizing offline-first data
