A Variable Node Optimization Model For Byzantine Fault Tolerant Systems, Ian Robert Fulton
A Variable Node Optimization Model For Byzantine Fault Tolerant Systems, Ian Robert Fulton
Masters Theses
“Byzantine Fault Tolerance (BFT) has been a major subject of study over the last two decades with increasing societal dependance on secure, correct, and reliable computer systems and online services. This research presents a model for high-level optimization of emerging systems that rely on these BFT algorithms and use a variable numbers of decision nodes. The model highlights the relationship between the security of a system and its efficiency. Two experiments were performed to determine system performance by varying the number of compromised nodes, decision nodes, and total nodes. They examine the probability that a transaction will be compromised based …
