Polkadot has announced a vote on Referendum 1890, proposing significant changes to its network staking architecture. The proposal requires Polkadot validators to lock at least 10,000 DOT of their own funds as self-stake. This reform is a prerequisite for the next major staking upgrade, which includes eliminating slashing risk for nominators and reducing the unbonding period from approximately 28 days to 24-48 hours. If passed, validators will bear slashing risks through higher self-bonding exposure, while nominators can continue earning staking rewards without exposing their principal to slashing risks, thereby reducing participation risk and expediting exits.
