Test Design

• Create a network with 15 Nodes with fast Epochs (1 Minute ?) 15 Nodes means 13 Nodes as sweet spot and 2 reserve nodes that are able to gather bonus scores. With the static early epoch end fault tolerance of 2, early epoch ends wont get triggered if 1 nodes passes out, but it triggers if 2 nodes pass out.

• Nodes will gather Bonus Score fast.

• After some Epochs, a node with a Bonus Score will get into the validator set.

• Shutdown 1 Node for this Epoch, verify if

  • The Validator looses the defined Bonus Score
  • The Validator does not get rewards

• Following Epoch, 13 Nodes out of the remaining 14 are chosen.

• Shutdown 1 Node: no Early Epoch should trigger

• Shutdown second Node: Early Epoch End should trigger.
