# Connect the nodes as a "chain". This allows us
# to split the network between nodes 1 and 2 to get
# two halves that can work on competing chains.
#
# Topology looks like this:
# node0 <-- node1 <-- node2 <-- node3
#
# If all nodes are in IBD (clean chain from genesis), node0 is assumed to be the source of blocks (miner). To
# ensure block propagation, all nodes will establish outgoing connections toward node0.
# See fPreferredDownload in net_processing.
#
# If further outbound connections are needed, they can be added at the beginning of the test with e.g.
# connect_nodes(self.nodes[1], 2)
