SPoS inherits PBFT's stability threshold: the three-phase pre-prepare, prepare, and commit protocol secures agreement despite Byzantine behavior, but formal analysis proves stability only while fewer than one third of nodes are faulty.

Source quote, verbatim

PBFT's three-phase protocol—pre-prepare, prepare, and commit—ensures agreement despite Byzantine behavior, with formal threshold analysis proving stability when fewer than n/3 of n nodes are faulty
