With the growing commercial interest in blockchains, permissioned implementations have
received increasing attention. Unfortunately, the BFT consensus algorithms that are the …

Byzantine Fault-Tolerant (BFT) protocols cover a broad spectrum of design dimensions from
infrastructure settings, such as the communication topology, to more technical features, such …

The byzantine fault-tolerance model captures a wide-range of failures-common in real-world
scenarios-such as ones due to malicious attacks and arbitrary software/hardware errors. We …

This chapter presents a state-of-the-art in the area of Byzantine consensus and its
application in blockchains. Bitcoin's blockchain is a secure, unmodifiable, append-only, log …

We propose WedgeChain, a data store that spans both edge and cloud nodes (an edge-
cloud system). WedgeChain consists of a logging layer and a data indexing layer. In this …

Blockchain as an enabler to current Internet infrastructure has provided many unique
features and revolutionized current distributed systems into a new era. Its decentralization …

Byzantine fault-tolerant protocols cover a broad spectrum of design dimensions from
environmental setting on communication topology, to more technical features such as …

The Practical Byzantine Fault Tolerance (PBFT) consensus in permissioned blockchains is
known for its strong consistency and engineering feasibility. However, research on dynamic …

Byzantine Fault-Tolerant (BFT) protocols have recently been extensively used by
decentralized data management systems with non-trustworthy infrastructures, eg …

Bandwidth is an essential resource for blockchain systems since BFT protocols require a
series of communication steps to reach a consensus. Reducing available bandwidth will …
