Novel Byzantine fault-tolerant (BFT) state machine replication protocols improve scalability
for their practical use in distributed ledger technology, where hundreds of replicas must …

To acheive maximum performance, Byzantine fault-tolerant (BFT) systems must be manually
tuned when hardware, network, or workload properties change. This paper presents our …

This paper articulates our vision for a learning-based untrustworthy distributed database. We
focus on permissioned blockchain systems as an emerging instance of untrustworthy …

Consensus is a fundamental problem in distributed systems, involving the challenge of
achieving agreement among distributed nodes. It plays a critical role in various distributed …

This paper introduces HotStuff-1, a BFT consensus protocol that improves the latency of
HotStuff-2 by two network-hops while maintaining linear communication complexity against …

Over the last few decades, a large body of research was carried out covering Byzantine
Fault Tolerance (BFT) systems. This research has brought forward new techniques …

When put under stress, traditional state-machine replication protocols typically exhibit
response times that by far exceed the average level of normal-case operation. The common …

Byzantine Fault Tolerant (BFT) protocols serve as a fundamental yet intricate component of
distributed data management systems in untrustworthy environments. BFT protocols exhibit …

Blockchain promises to make online services more fault tolerant due to their inherent
distributed nature. Their ability to execute arbitrary programs in different geo-distributed …

Each application developer desires to provide its users with consistent results and an
always-available system despite failures. Boldly, the CALM theorem disagrees. It states that …
