Techniques for utilizing trusted hardware components for mitigating the effects of equivocation amongst participant computing devices of a distributed system are described herein. For instance, a distributed system employing a byzantine-fault-resilient protocol&#x2014;that is, a protocol intended to mitigate (e.g., tolerate, detect, isolate, etc.) the effects of byzantine faults&#x2014;may employ the techniques. To do so, the techniques may utilize a trusted hardware component comprising a non-decreasing counter and a key. This hardware component may be 'trusted' in that the respective participant computing device cannot modify or observe the contents of the component in any manner other than according to the prescribed procedures, as described herein. Furthermore, the trusted hardware component may couple to the participant computing device in any suitable manner, such as via a universal serial bus (USB) connection or the like.
