Wu Shuo learned that Polkadot posted on Twitter that Polkadot OpenGov is currently voting on a major adjustment to the network staking architecture, with Referendum 1890 proposing 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 slashing, and unbonding time being shortened from approximately 28 days to about 24 to 48 hours.
If the proposal passes, validators will directly bear the risk of slashing through higher self-bond exposure, while nominators can continue to earn staking rewards without exposing their principal to slashing risk, thereby reducing participation risk and speeding up exit.
