v0.8.0-rc4

Fixed bugs:

• 0.8 rc3 - rewards still not working due to leader_logs.total or subsequent panic #1242
• update chain-deps and fix reward distribution panic #1246
• properly report error and failures of the terminating service #1243

⚠️ Breaking changes ⚠️ :

• update chain-deps and changed the UTxO signature #1246

v0.8.0-rc3

⚠️ breaking changes since 0.8.0-rc2: ⚠️

rewards were not properly distributed in 0.8.0-rc1 and 0.8.0-rc2. Because of this, the stake distribution will be different on a new node 0.8.0-rc3 starting with a blockchain 0.8.0-rc2 (or rc1). This will affect the leader schedules and the validity of the blocks.

house keeping

• don't add the block0 per-certificate fee if they are all not set (0) #1239

Bug fixes

• Node shutdowns are classified at wrong priority and exit successful #1236
• make the node actually return an error if a service was stopped because of error #1240
• don't fail the stuck notifier task if time is set in the future #1241

v0.8.0-rc2

Bug fixes

• 0.8.0-rc1: shutdowns, stability issues #1232

v0.8.0-rc1

New features/Breaking changes

• expose owner delegation certificate in jcli: jcli certificate new owner-stake-delegation
  this allows self delegation for account in a more efficient way.
• setting per certificate fees. Now it is possible to set different fees for the different kind of certificate (see genesis init documentation):

    # The fee calculations settings
  #
  # total fees: constant + (num_inputs + num_outputs) * coefficient [+ certificate]
  linear_fees:
    # this is the minimum value to pay for every transaction
    constant: 2
    # the additional fee to pay for every inputs and outputs
    coefficient: 1
    # the additional fee to pay if the transaction embeds a certificate
    certificate: 4
    # (optional) fees for different types of certificates, to override the one
    # given in `certificate` just above
    #
    # here: all certificate fees are set to `4` except for pool registration
    # and stake delegation which are respectively `5` and `2`.
    per_certificate_fees:
      # (optional) if not specified, the pool registration certificate fee will be
      # the one set by linear_fees.certificate
      certificate_pool_registration: 5
      # (optional) if not specified, the delegation certificate fee will be
      # the one set by linear_fees.certificate
      certificate_stake_delegation: 2
      # (optional) if not specified, the owner delegation certificate fee will be
      # the one set by linear_fees.certificate. Uncomment to set the owner stake
      # delegation to `1` instead of default `4`:
      # certificate_owner_stake_delegation: 1

• set the treasury initial funds and the treasury tax (the amount the treasury will take from the total reward pot, before serving the stake pools and delegators):

  # initial value the treasury will start with, if not set the treasury
  # starts at 0
  treasury: 1000000000000
  
  # set the treasury parameters, this is the tax type, just as in stake pool
  # registration certificate parameters.
  #
  # When distributing the rewards, the treasury will be first serve as per
  # the incentive specification document
  #
  # if not set, the treasury will not grow
  treasury_parameters:
    # the fix value the treasury will take from the total reward pot of the epoch
    fixed: 1000
    # the extra percentage the the treasury will take from the reward pot of the epoch
    ratio: "1/10"
    # It is possible to add a max bound to the total value the treasury takes
    # at each reward distribution. For example, one could cap the treasury tax
    # to 10000. Uncomment the following line to apply a max limit:
    # max_limit: 10000

• set the reward mechanism and how it will distribute rewards from the total reward supply:

  # Set the total reward supply available for monetary creation
  #
  # if not set there is no monetary creation
  # once emptied, there is no more monetary creation
  total_reward_supply: 100000000000000
  
  # set the reward supply consumption. These parameters will define how the
  # total_reward_supply is consumed for the stake pool reward
  #
  # There's fundamentally many potential choices for how rewards are contributed back, and here's two potential valid examples:
  #
  # Linear formula: constant - ratio * (#epoch after epoch_start / epoch_rate)
  # Halving formula: constant * ratio ^ (#epoch after epoch_start / epoch_rate)
  #
  reward_parameters:
    halving: # or use "linear" for the linear formula
      # In the linear formula, it represents the starting point of the contribution
      # at #epoch=0, whereas in halving formula is used as starting constant for
      # the calculation.
      constant: 100
  
      # In the halving formula, an effective value between 0.0 to 1.0 indicates a
      # reducing contribution, whereas above 1.0 it indicate an acceleration of contribution.
      #
      # However in linear formula the meaning is just a scaling factor for the epoch zone
      # (current_epoch - start_epoch / epoch_rate). Further requirement is that this ratio
      # is expressed in fractional form (e.g. 1/2), which allow calculation in integer form.
      ratio: "13/19"
  
      # indicates when this contribution start. note that if the epoch is not
      # the same or after the epoch_start, the overall contribution is zero.
      epoch_start: 1
  
      # the rate at which the contribution is tweaked related to epoch.
      epoch_rate: 3
