ChainCatcher News: 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 the total supply cap of DOT at 2.1 billion tokens; introduces DAP to replace the original treasury burn mechanism, with transaction fees, Coretime sales revenue, and slashing funds deposited into a permanent account for dynamic budget allocation; 13.14% of the remaining supply will be issued every two years, with the initial issuance phase reducing the current model by 53.6%.
Additionally, staking mechanisms will undergo significant updates: starting in mid to late March, validators will need to hold at least 10,000 DOT in self-stake that can be slashed, with 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 24-48 hours.
