Previous systems that support the dynamic adaptation of Byzantine
Fault Tolerant (BFT) protocols have important limitations such as:
lack of robustness (dependence on central and trustworthy components);
low flexibility (constraining the adaptation strategies); and lack of
extensibility (making it impossible to add new policies). To overcome
these gaps, this dissertation proposes a generic BFT adaptation
manager which can be used to execute different adaptation
policies. This manager is independent of the target service which
needs to be adapted dynamically and is, by itself, also tolerant to
Byzantine Faults. The manager has been implemented using BFT-SMaRt, a
well known open-source library. The experimental evaluation of the
resulting prototype illustrates that it can be used to effectively
increase the performance of a target BFT service in different
