Question 1
Which of these factors make distributed consensus hard? (check all that apply)
Nodes may crash (Correct, sad fact of life)
Nodes may be taken over by malware (Correct, that happens)
Encrypted messages may be intercepted and decrypted (Wrong, see below)
There is latency on the network (Correct, nodes cannot agree on sequences of events by timestamp)
if encrypted message can be decryted by attacker easily, we are in big trouble. And even if it does happen, that is not the reason why distributed consensus is hard.
