Scenario: Transactions are propagated through a network
     Given I have 8 seed nodes
     When I have a base node SENDER connected to all seed nodes
     When I have 8 base nodes connected to all seed nodes
     When I mine a block on SENDER with coinbase CB1
     When I mine 2 blocks on SENDER
     Then all nodes are at height 3
