Two PhD positions in distributed computing are open at Telecom Paris.


Large-scale distributed storage systems play an important role in the 
modern world, and their consistent and efficient operation is crucial.
The prominent blockchain technology aims at implementing a public 
”ledger”: a decentralized consistent history of transactions proposed by 
an open set of participating processes, with no static membership. In a 
static or properly reconfigurable system, the problem is typically 
solved using consensus-based state-machine replication algorithms, such 
as Paxos or PBFT. The crucial innovation of the Bitcoin protocol and its 
successors was to achieve strong consistency in the face of an adversary 
that can impersonate an arbitrary number of identities. The resulting 
protocols are, however, notoriously slow and energy-demanding, and an 
immediate question is whether these costs are unavoidable.

We intend to focus on consistency and scalablility of compositions of 
blockchain-like systems.  We intend to characterize the model 
assumptions that enable generic blockchain interactions in a consortium 
or an open system. We also plan to explore the space of consistency 
definitions that enable generalizations of  "cross-chain" transactions. 
Besides establishing provable complexity and computability bounds, the 
project intends to develop system prototypes that are not only formally 
proved correct but also studied experimentally.

Located in the Paris area,Telecom Paris (formerly known as ENST or École 
nationale supérieure des télécommunications) is one of the top French 
public institutions of higher education and research (Grandes Écoles), a 
founding member of Institut Polytechnique Paris. In collaboration with 
EPFL, it has established Institut Eurécom at Sophia-Antipolis.


The positions are open for three years starting in 2019-2020.

The positions are offered to both foreign and French students who hold a 
Master degree in computer science.Solid mathematical background, basic 
knowledge of distributed algorithms, basic concurrent programming
