Wu Shuo learned that Polkadot posted on Twitter that Polkadot OpenGov is voting on a major network staking architecture adjustment, and Referendum 1890 proposes that Polkadot validators lock at least 10,000 DOT of their own funds as self-stake.

This reform is a mandatory prerequisite for the next major staking upgrade, which includes changes such as nominators no longer bearing the risk of confiscation, and the unbonding period being shortened from about 28 days to approximately 24 to 48 hours.
If the proposal passes, validators will directly bear the risk of confiscation through higher self-bonding exposure, while nominators can continue to earn staking rewards without exposing their principal to confiscation risk, thereby reducing participation risk and speeding up exit.
