@NicolasDP NicolasDP released this Dec 11, 2019

new features

  • GraphQL/Explorer mode exposes new objects like treasury balance and settings #1242 #1247
  • jcli debug block to see the content of a block (or the leet feature) #1337
  • new incentive parameters to encourage stake pool creation: #1338
    # set some reward constraints and limits
    #
    # this value is optional, the default is no constraints at all
    reward_constraints:
      # limit the epoch total reward drawing limit to a portion of the total
      # active stake of the system.
      #
      # for example, if set to 10%, the reward drawn will be bounded by the
      # 10% of the total active stake.
      #
      # this value is optional, the default is no reward drawing limit
      reward_drawing_limit_max: "10/100"
    
      # settings to incentivize the numbers of stake pool to be registered
      # on the blockchain.
      #
      # These settings does not prevent more stake pool to be added. For example
      # if there is already 1000 stake pools, someone can still register a new
      # stake pool and affect the rewards of everyone else too.
      #
      # if the threshold is reached, the pool doesn't really have incentive to
      # create more blocks than 1 / set-value-of-pools % of stake.
      #
      # this value is optional, the default is no pool participation capping
      pool_participation_capping:
        min: 300
        max: 1000

⚠️ Breaking changes: ⚠️

  • remove useless block0 parameter: BFT Slots Ratio #1293
  • BlockContent Size: finally set the right value for number of fragments #1288

I.e., in the genesis file it is now required to set:

blockchain_configuration:
  # set the maximum block content size (in bytes)
  block_content_max_size: 1024000

and the following value is no longer possible to set:

 blockchain_configuration:
   # ...
 
- max_number_of_transactions_per_block: {default_max_number_of_transactions_per_block}

-  # Genesis praos parameter D
-  #
-  # default value: {default_bft_slots_ratio}
-  bft_slots_ratio: {default_bft_slots_ratio}

Implemented enhancements:

  • Add proper depth #1295
  • spawn blockchain process to allow for more concurrent action to happen #1290

Fixed bugs:

  • jormungandr v0.8.0-rc7 got stuck on synchronisation #1284
  • jormungandr 0.8.0-rc5-cecea4d got stuck on synchronisation #1273
  • Spamming the test net appears to break it or at least cause multiple node stalls long after the spamming stops #1235
  • 0.7.5 (or nightly testnet) - generated blocks are not added to the blockchain #1221
  • 0.7.4 - Blocks not getting added to chain #1220
  • 0.7.1 Frequent Warning - WARN blockchain is not moving up.... #1183
  • prevent panic if the given chain advance is removed from concurrent processing #1296
