Le LaBRI (Laboratoire Bordelais de Recherche en Informatique) organise le Mardi 14 Novembre 2017 au matin un séminaire sur le thème des blockchains. À cette occasion, Dr. Marko Vukolic (expert Hyperledger, IBM Research, Zurich) fera un exposé présentant ses derniers travaux sur le sujet. Cet exposé sera suivi d’une table ronde avec plusieurs industriels et académiques déjà actifs ou potentiellement intéressés par cette thématique (ATOS, CATIE, Valorem, Région Nouvelle-Aquitaine, …).

Programme détaillé :

• 9h30-10h : Accueil café.
• 10h-11h : Présentation de Marko Vukolic “Hyperledger Fabric: a Distributed Operating System for Permissioned Blockchains” (détails ci-dessous).
• 11h-12h : Table ronde sur les activités autour de la thématique Blockchain. Interventions des industriels de la région bordelaise. 12h : Cocktail et networking.

L’inscription est gratuite et ouverte à tous mais obligatoire : remplir le sondage ici (avant le 9 Novembre).

Lieu : Amphithéâtre LaBRI, Université de Bordeaux, Bat. A30, 351, cours de la Libération, Talence. Date : 14 Novembre 2017 à 9h30. Contact : Daniel Négru (daniel.negru@labri.fr, 05.56.84.23.25).

Title:

Hyperledger Fabric: a Distributed Operating System for Permissioned Blockchains

Abstract: 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.

Bio: Dr. Marko Vukolić is a Research Staff Member at IBM Research - Zurich. Previously, he was a faculty at EURECOM and a visiting faculty at ETH Zurich. He received his PhD in distributed systems from EPFL in 2008 and his engineer’s degree in telecommunications from University of Belgrade in 2001. His research interests lie in the broad area of distributed systems, including blockchain and distributed ledgers, cloud computing security, distributed storage and fault-tolerance.
