Blockchain is a technology making the shared registry concept from distributed systems a
reality for a number of application domains, from the cryptocurrency one to potentially any …

Byzantine fault-tolerant (BFT) state-machine replication makes it possible to design systems
that are resilient against arbitrary faults, a requirement considered crucial for an increasing …

The core technical component of blockchains is consensus: how to reach agreement among
a distributed network of nodes. A plethora of blockchain consensus protocols have been …

Fabric is a modular and extensible open-source system for deploying and operating
permissioned blockchains and one of the Hyperledger projects hosted by the Linux …

Recent advances in the industrial Internet of things (IIoT) provide plenty of opportunities for
various industries. To address the security and efficiency issues of the massive IIoT data …

The surprising success of cryptocurrencies has led to a surge of interest in deploying large
scale, highly robust, Byzantine fault tolerant (BFT) protocols for mission-critical applications …

Current blockchain platforms, especially the recent permissioned systems, have
architectural limitations: smart contracts run sequentially, all node executes all smart …

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

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 …

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 …
