Hyperledger Fabric: a Distributed Operating System for Permissioned Blockchains

Hyperledger Fabric is an open-source system that provides a modular and extensible platform for deploying and operating permissioned blockchains (distributed ledgers). Starting from the premise that there is no ‘one-size-fits-all‘ distributed consensus protocol, Hyperledger Fabric is the first blockchain system to support pluggable consensus protocols which allows the system to be tailored to particular use cases and trust models. Hyperledger Fabric also features a radically different architecture compared to its predecessors, with the goals of facilitating blockchain performance, scalability, confidentiality and modularity. Unlike other blockchain systems that require their distributed applications to be written in domain-specific languages, Hyperledger Fabric allows the development of distributed applications/smart-contracts in general-purpose programming languages, without dependency on a specific cryptocurrency. Satisfying these requirements required an overhaul of state-of-the-art permissioned blockchain design and rethinking the way blockchains cope with non-determinism, resource exhaustion and performance attacks.

In this talk we discuss Hyperledger Fabric architecture, detailing the rationale behind various design decisions. We also briefly discuss distributed ledger technology (DLT) use cases to which Hyperledger Fabric is relevant, including financial industry, manufacturing industry, supply chain management, government use cases and many more.
