Abstract: This talk will briefly recall my last decade in LASIGE/DI and overview some of our recent ongoing works on efficient, dependable large-scale systems. More specifically, I will describe our results from a recent theoretical study about auditable storage emulations, where we identified tight bounds and impossibility results for auditors reporting who has effectively read data in resilient information dispersal schemes. These results have immediate practical consequences since enabling such an auditability in most (if not all) of the existent information dispersal solutions demands f to 2f more objects than the minimal default configurations they foresee.
