Polkadot’s RFC-0092 proposal aims to reduce the unstaking period for staked tokens from 28 days to just two days, significantly enhancing user convenience. This new mechanism, introduced by Web3 Foundation researchers, involves a queue system that adjusts unbonding durations based on the queue size. If approved, the minimum unbonding time could drop to two days when the queue is empty, without exceeding the current 28-day maximum. This proposal addresses the high unbonding period in Polkadot, aiming to make staking more attractive and competitive​ (Blockchair)​.
