Abstract—Replication is a well-established approach to increasing database availability. Many database replication protocols have been proposed for the crash-stop failure model, ...
In this paper we demonstrate how stateful Byzantine Fault Tolerant services may be hosted on a Chord ring. The strategy presented is fourfold: firstly a replication scheme that di...

Byzantine fault-tolerant (BFT) replication has enjoyed a series of performance improvements, but remains costly due to its replicated work. We eliminate this cost for read-mostly ...
A fault-scalable service can be configured to tolerate increasing numbers of faults without significant decreases in performance. The Query/Update (Q/U) protocol is a new tool t...

Traditional agreement-based Byzantine fault-tolerant (BFT) systems process all requests on all replicas to ensure consistency. In addition to the overhead for BFT protocol and sta...
