Feature: Staking & Delegation - scenarios focusing on initial epoch

  Background:
    Given the following network parameters are set:
      | name                                              |  value  |
      | reward.asset                                      |  VEGA   |

      | reward.staking.delegation.delegatorShare          |  0.883  |
      | reward.staking.delegation.minimumValidatorStake   |  100    |
      | reward.staking.delegation.maxPayoutPerParticipant |  100000 |
      | reward.staking.delegation.competitionLevel        |  1.1    |

      | reward.staking.delegation.optimalStakeMultiplier  |  5.0    |
  
    And the average block duration is "1"
    And time is updated to "2021-09-10T00:00:00Z"
 
    And the validators:
      | id     | staking account balance |
      | node1  |         1000000         |
      | node2  |         1000000         |
      | node3  |         1000000         |
      | node4  |         1000000         |
      | node5  |         1000000         |

      | node13 |         1000000         |

  Scenario: No delegation in the first epoch (0061-REWP-additional-tests)

    
    Then the network moves ahead "172804" blocks

    And the parties receive the following reward for epoch 1:
      | party  | asset | amount |
      | node1  | VEGA  |     0  | 
      | node2  | VEGA  |     0  |

      | node12 | VEGA  |     0  | 
      | node13 | VEGA  |     0  | 

    Then the network moves ahead "86403" blocks

    And the parties receive the following reward for epoch 2:
      | party  | asset | amount |

      | node12 | VEGA  |     0  | 
      | node13 | VEGA  |     0  | 

    And the parties deposit on asset's general account the following amount:
      | party  | asset  | amount |
      | party1 | VEGA   | 111000 |

    And the parties deposit on staking account the following amount:
      | party  | asset  | amount |
      | party1 | VEGA   | 111000 |  

    #set up the self delegation of the validators (number of validators < min. validators parameter)
    Then the parties submit the following delegations:
      | party  | node id  | amount |
      | node1  |  node1   |  11000 | 
      | node2  |  node2   |  12000 |

      | node4  |  node4   |     99 | 
      | party1 |  node4   | 111000 | 

    And the parties should have the following delegation balances for epoch 4:
      | party  | node id  | amount |
