Special Announcement for Delegators

,

Dear Delegators

We have an important announcement regarding the StakePoolV2 on-chain function upgrade. The upgrade will begin on December 15th and is expected to be a complex process. We have prepared a list of potential impacts in the proposal.

Please take the time to review the information and follow our suggestions to avoid any impact on your owner rewards. The main time points to be aware of during this upgrade and the main impacts on you are as follows:

On December 15th at 8:00 AM UTC, the StakePoolV2 on-chain function upgrade will begin.

  • Suspend the heartbeat event of GK to suspend the issuance of computing power rewards.
  • Workers will no longer enter the unresponsive state. (During this time, worker registration, starting or stopping work on the chain can still be performed manually, and the transaction module on the chain will be normal.)
  • Temporarily cancel the mandatory Coolingdown function when the StakePool Withdrawal queue expires until the upgrade is complete.

On December 16th (specific time to be determined)

  • Suspend functions related to workers, StakePool, and delegation on the chain. At that time, it will not be possible to initiate any on-chain transactions for the above three parts.
  • Suspend Council Elections.
  • The Delegate and Mining pages on the Phala App will pause.
  • New versions of pRuntime and PRB will be released, and compute providers can start updating the pRuntime and PRB modules in their workers.

On December 21st (specific time to be determined), the upgrade on the chain will be complete

  • Reactivate on-chain functions related to workers, StakePool, and delegation. At that time, you can manually operate worker registration, start or stop mining through polkadot.js, and you can make StakePool/Vault management and Delegation adjustments.

On December 22nd (specific time to be determined)

  • the Phala App 2.0 will officially launch.

On December 23rd at 8:00 AM UTC

  • Restore GK’s heartbeat event.
  • After GK resumes, in the first heartbeat event of each worker, all computing power rewards during the entire suspension period will be reissued.

On December 26th (specific time to be determined)

  • Restore the forced Coolingdown function after the StakePool Withdrawal queue expires.

For these key time points, the following two points will have a special impact on you:

  1. From December 15th to December 23rd, you will not be able to receive delegator rewards in a timely manner. All rewards during this period will be distributed after the heartbeat event resumes on December 23rd. Please ensure that your delegation is in the StakePool on the 23rd and the next few days to avoid missing the reward distribution.
  2. From December 15th to December 25th, your delegation may not be withdrawn. Due to the suspension of on-chain functions, regardless of the situation in the StakePool, you will not be able to operate withdrawals and delegation from December 16th to December 21st. To make sure the delayed payment of rewards can be issued smoothly after the upgrade, we have decided to temporarily cancel the mandatory Coolingdown function in the StakePools. From December 15th to December 25th, if your delegation is in the withdrawal queue and there is no free delegation in the StakePool, it cannot be withdrawn. The mandatory Coolingdown function will resume on December 26th, and all StakePools with withdrawal queues exceeding 7 days will be forced to shut down.

The above two points are the core content that delegators need to pay attention to during the upgrade process. You do not need to perform any other operations during the upgrade process. In this upgrade, we will be launching the Vault function. Please actively participate."
