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: 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.
Book ChapterDOI
An Information-Theoretic Model for Steganography
TL;DR: An information-theoretic model for steganography with passive adversaries is proposed and several secure steganographic schemes are presented; one of them is a universal information hiding scheme based on universal data compression techniques that requires no knowledge of the covertext statistics.
Book ChapterDOI
Computationally private information retrieval with polylogarithmic communication
TL;DR: A single-database computationally private information retrieval scheme with polylogarithmic communication complexity based on a new, but reasonable intractability assumption, which is essentially the difficulty of deciding whether a small prime divides φ(m), where m is a composite integer of unknown factorization.

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.

Blockchain Consensus Protocols in the Wild
Christian Cachin,Marko Vukolic +1 more
TL;DR: The process of assessing and gaining confidence in the resilience of a consensus protocols exposed to faults and adversarial nodes is discussed, and the consensus protocols in some prominent permissioned blockchain platforms with respect to their fault models and resilience against attacks are reviewed.
