Centrifuge 0.10.19 - Release Notes Highlights

Upgrade Priority: ❗️ High ❗️Collator Nodes should upgrade as soon as possible after the runtime upgrade has been enacted. Upgrading beforehand can lead to block production issues since EVM functionality was added.

  • Add block rewards as proposed in CP6 (#1198, #1342)
    • Time-wise, rewarding is tightly coupled to sessions (6h in block time) in contrast to epochs (12h) from CP6. Thus, the proposed amounts are halved and rewarded in 6 hour periods (see technical spec for more details)
    • Collator rewards = 16.65 CFG per collator per epoch / 2 sessions per epoch = 8.325 CFG = 8325 * MILLI_CFG per collator
    • Total rewards = 20,096 CFG per epoch / 2 sessions per epoch = 10048 CFG
    • Treasury rewards = Total rewards - Collator rewards
  • Add EVM wallet support (#1252, #1349)
    • Until we enable full EVM support soon™️, the production runtimes filter all non-root calls to the EVM pallet and disallow creating contracts via the EVM RPC calls
  • Upgrade to Polkadot v0.9.37 (#1241)

Breaking changes

  • Loans: LoanId out from ActiveLoan (#1367)
  • Loans: Add unchecked amount support by (#1368)
  • Loans: Add multiple triggers for write-offs (#1314)
  • Loans: Adapt to Oracle valuation implementation (#1311)

Migrations

This upgrade includes multiple smaller migrations.

  • Block rewards: Sets up the required block rewards storage for our current collators. (#1342)
    • Without this migration, none of the collators would be eligible to claim rewards.
  • Block rewards base: Mints ExistentialDeposit worth 1 µCFG to the sovereign account of the BlockRewardsBase (#1342)
    • Without this migration, not all rewards can be claimed from the reward recipients.
  • Session: Clones the existing AuRa session keys for every collator to the new block_rewards entry of SessionKeys (#1342)
    • Without this migration, all of our collators would have to update their session keys manually. E.g., none of the collators would actually be recognized by the session transition inside pallet_block_rewards because the block_rewards entry of SessionKeys is unset.
  • Loans: Updates the WriteOffPolicy storage as a result of #1314
  • Asset registry: Sets the AssetMetadata.location of all the Tranche tokens registered in the AssetRegistry to None (#1340)
  • EVM: Sets our parachain ID 2031 as our EVM chain id (#1349)

Altair 0.10.27 - Release Notes Highlights

Upgrade Priority: ❗️ High ❗️Collator Nodes should upgrade as soon as possible after the runtime upgrade has been enacted. Upgrading beforehand can lead to block production issues since EVM functionality was added.

  • Adds automatic payout of collator block rewards with amounts approved in RFC from December 2022

    • Time-wise, rewarding is tightly coupled to sessions (6h in block time) in contrast to epochs (12h) from CP6. Thus, the proposed amounts are halved and rewarded in 6 hour periods (see technical spec for more details)
    • Collator rewards: 12000 AIR per collator per month / 30.417 days per month / 4 sessions per day = 98.63 AIR = 98630 MILLI_AIR per session per collator
    • Treasury rewards = 0
    • Total rewards = Collator rewards * MaxCollators
      • Every session, total_collator_rewards = reward_per_collator * collator_count is minted into the Treasury and the remainder total_rewards - total_collator_rewards is automatically dropped since the Beneficiary is set to empty ()
      • Thus, total_rewards only serves as a theoretical upper bound which just needs to ensure it suffices for collator rewards

  • Add EVM wallet support (#1252, #1349)

    • Until we enable full EVM support soon™️, the production runtimes filter all non-root calls to the EVM pallet and disallow creating contracts via the EVM RPC calls

  • Upgrade to Polkadot v0.9.37 (#1241)

  • Loans: LoanId out from ActiveLoan (#1367)
