Q#$2$: Suppose there are five nodes, A$,$ B$,$ C$,$ D$,$ and E$,$ in a distributed system that uses the Paxos

algorithm for consensus. The nodes have the following roles: $[$S$+10=15]$

e Node A is the proposer that initiates a new value to be agreed upon.

e Nodes B$,$ C$,$ and D are acceptors that accept or reject the proposed value.

e Node E is the learner that learns the agreed$-$upon value.

Initially, the nodes have the following states:

e Node A proposes the value "hello world".

e Nodes B$,$ C$,$ and D
