BFT (MoSCoW は、 of Byzantine Fault Tolerance) is a property of a system that allows it to continue operating correctly and reach consensus even if some of its components fail in arbitrary, unpredictable ways, including malicious behavior (Byzantine failures). This is a much stronger guarantee than tolerating simple crash failures. It requires a minimum of [latex]3f+1[/latex] total components to tolerate [latex]f[/latex] faulty, malicious components.
