Marianna Belotti, industrial Ph.D. student in collaboration with French public bank Caisse des Dépôt et Consignations (CDC), will defend her Ph.D. thesis on December 16, 2021, at 4:00 p.m, in the “Boris Vian” Thesis Room (37.2.43) at CNAM, 2 rue Conté, 75003 Paris, France.
Marianna worked on strategic modeling of blockchain and Bitcoin node interactions, and she will then continue her career at the European Central Bank.
Thesis Title: Game Theoretical Analysis of Blockchain Users’ Behaviors
Thesis Title (French): Analyse via la théorie des jeux sur les comportements des utilisateurs blockchain
Abstract:
The disruptive technology born in 2008 with Bitcoin and known as blockchain represents a significant quality leap from the distributed database technology. Distributed systems theory provides then models and techniques to analyze some protocols characterizing the technology, however in order to analyze a blockchain system additional considerations on its users need to be done. This thesis aims at analyzing the different behaviors of the users operating in blockchains or more in general in DLTs (i.e., Distributed Ledger Technologies).The latter are considered as rational agents, fully aware of all actions available to them and capable of choosing the one they feel is the best for themselves. Game theory is then used to model situations where users are called to choose and perform certain actions within the DLT environment. This thesis analyzes different users as well as different blockchains with the scope of providing a general overview on the topic and formal results on their behaviors ; users may indeed be honest vis-à-vis of other users or they may behave maliciously (as Byzantine nodes) attacking the blockchain system.
