I'm pretty sure that Byzantine General protection has been advised for more than 15 years.  It's in the NTPv4 RFC, so it is at least just short of 13 years. <https://www.ietf.org/rfc/rfc5905.txt>

I meant to include this quote:

        /*
         * There must be at least NSANE survivors to satisfy the
         * correctness assertions.  Ordinarily, the Byzantine criteria
         * require four survivors, but for the demonstration here, one
         * is acceptable.
