Polkadot will adjust its economic structure starting from March 12, with a total supply cap of 2.1 billion DOT

By: rootdata|2026/03/02 20:45:00

Polkadot will implement several changes starting from March 12, 2026, including a new DOT issuance model, the introduction of a Dynamic Allocation Pool (DAP), and adjustments to staking, budget allocation, and network security mechanisms.

The proposal sets the total supply cap of DOT at 2.1 billion; it introduces a Dynamic Allocation Pool (DAP) to replace the original treasury destruction mechanism, depositing transaction fees, Coretime sales revenue, and slashing funds into a permanent account for dynamic budget allocation; 13.14% of the remaining supply will be issued every two years, with the initial issuance amount reduced by 53.6% compared to the current model.

In addition, the staking mechanism will also undergo significant updates: starting from mid to late March, validators will need to hold at least 10,000 DOT in a slashing-capable self-stake and set a minimum commission rate of 10%; from April, nominators will become non-slashable, and the unbonding period will be significantly shortened from 28 days to 24 to 48 hours.
