Decentralized systems are symmetric distributed systems, where each participating node can in principle assume any of the required tasks. Such systems have enjoyed tremendous interest in recent years, sparked by the fact that decentralization is an enabler for new paradigms like cooperative computing (e.g., peer-to-peer systems), ad hoc networking applications, and highly resilient network services.
These application domains present formidable new challenges to decentralized system design. Practical systems must be self-organizing and extend to planetary scale. They must tolerate heterogeneity, dynamic membership and mobility. And, they must provide provable guarantees and consistency despite complex, correlated failures, mutual suspicion, lack of trusted authorities, and selfish or malicious participants.
In this talk, I will outline the state-of-the-art in modern decentralized system design, sketch existing and future applications and identify key challenges that remain.

Pascal Déchamboux , Ph.D., is a senior architect at the research centre of France Telecom.
His research work concerns middleware support
service delivery environment. He has been the manager for several years
research team that focuses on two main middleware topics:
- work on component support that lead to the proposition of the Fractal component model and its Julia implementation, complemented with management capabilities.
- work on persistence support that lead to the proposition of several frameworks such as mapping subsystem managing typed I/Os (e.g., O/R mapping), transactional data manager, cache manager or concurrency manager, for building persistence supports complying with different standards like EJB or JDO.
He has been involved in many national and international collaborative projects, especially with Bull and INRIA. He is one of the co-founders of the ObjectWeb open source community within which results of the previously mentioned works can be found and used with no restriction!
