Polkadot plans to implement an economic model reform starting March 12, with the total supply of DOT to be capped at 2.1 billion.

Foresight News reports that Polkadot will implement a series of economic architecture adjustments starting March 12, 2026. The core of this reform includes: setting the maximum supply of DOT at 2.1 billions; introducing a Dynamic Allocation Pool (DAP) to replace the original treasury burn mechanism, with transaction fees, Coretime sales revenue, and slashed funds deposited into a permanent account for dynamic budget allocation; issuing 13.14% of the remaining supply every two years, with the first phase issuance reduced by 53.6% compared to the current model. In addition, the staking mechanism will undergo major updates: from mid to late March, validators must hold at least 10,000 DOT in slashable self-stake and set a minimum commission rate of 10%; starting in April, nominators will become non-slashable, and the unbonding period will be significantly shortened from 28 days to 24 to 48 hours.
