Notice: For safety considerations, we recommend that all PoS staking nodes change their PoS keys once after the v2.2.0 upgrade (November 17th).
Guide
How to change PoS Key
1.Unlock all locked votes at https://governance.confluxnetwork.org/en/pos/
2.The part that has been staked for 13 days will be unlocked 1 day later. The part that is staked no more than 13 days will be unlocked 14 days after staking.
3.Once the PoS staked votes go to 0, you can generate a new PoS key with the latest node (after v2.2.0) and re-register it (PoS node tutorial: Running a PoS node on AWS - Server Setup & Node Configuration).
Note: For mining pool nodes, please find: Announcement and Guide for mining pool PoS node operators changing PoS keys:Announcement and Guide for mining pool PoS node operators changing PoS keys
In the near future, we will publicly disclose the details of the security update to v2.2.0, and PoS keys that have not been upgraded may be at higher risk by then.
