Abstract:
Resilient computing is attracting attention, driven by the increasing number of systems and applications that no longer take as a given: static architecture configurations, known and fixed number of participants, stable system assumptions like synchrony, moderate or predictable threat/fault behaviours, or unconditional trust in stakeholders/third parties. I will briefly discuss a research approach to resilient (distributed) computing, which has allowed my lab CritiX to tackle several application areas using the same coherent set of enabling techniques and paradigms.
Blockchain being one of them, the bulk of the talk will exemplify that philosophy, addressing the challenges faced when you go about conceiving a distributed fault/intrusion tolerant and resilient system … that ends-up implementing a blockchain. More exactly, a high-speed permissionless blockchain protocol secure against attackers with way more than 51% network computing power, and resilient to all attacks known at date of publication.

Paulo Esteves-Veríssimo is a Professor and FNR PEARL Chair at the University of Luxembourg (UL), and head of the CritiX research group at UL's SnT Centre (http://wwwen.uni.lu/snt). He is adjunct Professor of the ECE Dept. of CMU (USA). Veríssimo is Fellow of IEEE and of ACM. He is past Chair of the IFIP WG 10.4 on Dependable Computing and Fault-Tolerance and past vice-Chair of the Steering Committee of the DSN conference. He is also associate editor of the IEEE Transactions on Emerging Topics in Computing. He is interested in resilient, secure and dependable distributed architectures, middleware and algorithms for: resilience of large-scale systems and critical infrastructures, privacy and integrity of biomedical and blockchain data, security and safety of real-time networked embedded systems. He is author of over 200 peer-refereed publications and co-author of 5 books. Check his pubs on GSC: http://scholar.google.com/citations?user=aMHx8aUAAAAJ
