Byzantine node

WebCall a node common if val'(w, i) = val'(w, j) for all non-faulty i, j. Lemma above says wk is common if k is good. With n ≥ 3f+1, taking majorities ensures any parent of only common nodes is also common. Observe that every path has a common node on it, since a path travels through f+1 nodes and one of them is good. Web–Node crashes –Network partitions • A RSM w/ 2f+1 replicas can tolerate f simultaneous crashes Byzantine faults • Nodes fail arbitrarily –Failed node performs incorrect computation –Failed nodes collude • Causes: attacks, software/hardware errors •Examples: –Client asks bank to deposit $100, a Byzantine bank server substracts ...
