Technology scaling and a continual increase in operating frequency have been the main
driver of processor performance for several decades. A recent slowdown in this evolution is …

We are increasingly relying on online services to store, access, share, and disseminate
critical information from anywhere and at all times. Such services include email, digital …

Byzantine fault-tolerant state machine replication (BFT-SMR) replicates a state machine
across a set of replicas, and processes requests as a single machine even in the presence …

We present two asynchronous Byzantine fault-tolerant state machine replication (BFT)
algorithms, which improve previous algorithms in terms of several metrics. First, they require …

When provided with more powerful or extra hardware, state-of-the-art Byzantine fault-
tolerant (BFT) agreement protocols are unable to effectively exploit the additional computing …

We demonstrate a framework that simplifies the performance evaluation of fault tolerant
State Machine Replication in the permissioned model. ABCperf offers a message passing …

Protocols for state-machine replication (SMR) often trade off performance for resilience to
network delay. In particular, protocols for asynchronous SMR tolerate arbitrary network delay …

Researchers have made great strides in improving the fault tolerance of both centralized
and replicated systems against arbitrary (Byzantine) faults. However, there are hard limits to …

Byzantine fault tolerance (BFT) can preserve the availability and integrity of IoT systems
where single components may suffer from random data corruption or attacks that can expose …

Emerging networking technologies have complex network interfaces that have renewed
concerns about network reliability. In this paper, we present an effective low-overhead fault …
