Elli Androulaki,Artem Barger,Vita Bortnikov,Christian Cachin,Konstantinos Christidis,Angelo De Caro,David Michael Enyeart,Christopher Ferris,Gennady Laventman,Yacov Manevich,Srinivasan Muralidharan,Chet Murthy,Binh Nguyen,Manish Sethi,Gari Singh,Keith Smith,Alessandro Sorniotti,Chrysoula Stathakopoulou,Marko Vukolic,Sharon Weed Cocco,Jason Yellick +20 more
TL;DR: This paper describes Fabric, its architecture, the rationale behind various design decisions, its most prominent implementation aspects, as well as its distributed application programming model, and shows that Fabric achieves end-to-end throughput of more than 3500 transactions per second in certain popular deployment configurations.

Hyperledger Fabric: A Distributed Operating System for Permissioned Blockchains.
Elli Androulaki,Artem Barger,Vita Bortnikov,Christian Cachin,Konstantinos Christidis,Angelo De Caro,David Michael Enyeart,Christopher Ferris,Gennady Laventman,Yacov Manevich,Srinivasan Muralidharan,Chet Murthy,Binh Nguyen,Manish Sethi,Gari Singh,Keith Smith,Alessandro Sorniotti,Chrysoula Stathakopoulou,Marko Vukolic,Sharon Weed Cocco,Jason Yellick +20 more
TL;DR: The Fabric project as mentioned in this paper is a permissioned blockchain system for distributed applications written in standard, general-purpose programming languages, without systemic dependency on a native cryptocurrency, which allows the system to be tailored to particular use cases and trust models.

Mir-BFT: High-Throughput BFT for Blockchains.
TL;DR: Mir is a generalization of the celebrated and scrutinized PBFT protocol, with changes needed to accommodate novel features restricted to PBFT liveness, and achieves unprecedented throughput on WANs without sacrificing latency, robustness to malicious behavior, or even performance in clusters.
Proceedings ArticleDOI
State machine replication scalability made simple
TL;DR: This work presents Insanely Scalable State Machine Replication, a generic construction to turn leader-driven protocols into scalable multi-leader ones and improves the peak throughput of PBFT, HotStuff, and Raft by 37x, 56x, and 55x, respectively, at a scale of 128 nodes.

Mir-BFT: High-Throughput Robust BFT for Decentralized Networks
TL;DR: Mir-BFT as discussed by the authors is a robust Byzantine fault-tolerant (BFT) total order broadcast protocol aimed at maximizing throughput on wide-area networks (WANs), targeting deployments in decentralized networks, such as permissioned and Proof-of-Stake permissionless blockchain systems.
