Consensus algorithms are applied in the context of distributed computer systems to improve
their fault tolerance. The explosive development of distributed ledger technology following …

Recent developments in blockchain technology have inspired innovative new designs in
resilient distributed and database systems. At their core, these blockchain applications …

A blockchain is an append-only linked-list of blocks, which is maintained at each
participating node. Each block records a set of transactions and their associated metadata …

Blockchain serves as a replicated transactional processing system in a trustless distributed
environment. Existing blockchain systems all rely on an explicit ordering step to determine …

Recently, we saw the emergence of consensus-based database systems that promise
resilience against failures, strong data provenance, and federated data management …

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 recent surge in federated data management applications has brought forth concerns
about the security of underlying data and the consistency of replicas in the presence of …

The problem of distributed consensus has played a major role in the development of
distributed data management systems. This includes the development of distributed atomic …

Most methods for Byzantine fault tolerance (BFT) in the partial synchrony setting divide the
local state of the nodes into views, and the transition from one view to the next dictates a …

Recently, stateless blockchains have been proposed to alleviate the storage overhead for
nodes. A stateless blockchain achieves storage-consensus parallelism, where storage …
