Question 2
Why is Bitcoin able to reach consensus in practice despite this being a generally difficult problem? (check all that apply)
Financial incentives cause participants to work together (Correct, without the 25 BTC I won't go competiting for creating blocks)
Only small groups of nodes have to reach consensus rather than the network having to globally reach consensus (Wrong, that's not the goal, the goal is for all correct node to agree on a single truth)
The order of blocks doesn’t matter for consensus (Wrong, they also have to agree on order)
Consensus only has to be reached over long time scales (Correct)
