ChainCatcher reports that Polkadot will implement several changes starting March 12, 2026, including a new DOT issuance model, the introduction of Dynamic Allocation Pools (DAP), and adjustments to staking, budget allocation, and network security mechanisms. The proposal sets a maximum total supply of 2.1 billion DOT; introduces Dynamic Allocation Pools (DAP) to replace the existing treasury burn mechanism, directing transaction fees, Coretime sales revenue, and slashes into a permanent account for dynamic budget allocation; and issues 13.14% of the remaining supply every two years, with the initial issuance volume reduced by 53.6% compared to the current model. Additionally, staking mechanisms will undergo major updates: starting mid-to-late March, validators must hold at least 10,000 DOT of slashable self-stake and set a minimum commission rate of 10%; beginning in April, nominators will become non-slashable, and the unbonding period will be significantly shortened from 28 days to 24 to 48 hours.

Summary
On March 12, 2026, Polkadot will adjust its economic framework, capping the DOT supply at 2.1 billion. The update introduces a Dynamic Allocation Pool to replace the treasury burn mechanism and reduces initial issuance by 53.6%. Staking rules are updated, requiring validators to hold 10,000 DOT in slashable self-staking and imposing a minimum 10% commission. Nominators will gain non-slashable status in April, and unstaking periods will be shortened to 24–48 hours. These changes align with broader CFT initiatives and aim to strengthen Polkadot’s positioning as a risk-on asset.
