Polkadot cuts DOT issuance from 120M to 55M, lowers inflation to 3.1%, and introduces a fixed supply cap of 2.1B tokens.
Polkadot has introduced a major change to its token economy after approving a new governance proposal that limits the total supply of DOT and reduces yearly token issuance.
The update marks a structural shift in how the network manages inflation, staking rewards, and treasury funding.
The redesign introduces a fixed supply cap of 2.1 billion DOT and lowers inflation as the network adjusts its long-term economic framework.
Polkadot Introduces Fixed Supply and Lower Inflation
Polkadot has officially introduced a maximum supply cap of 2.1 billion DOT, ending the network’s earlier open issuance model.
The change was approved through Referendum 1710, which received around 81% approval from governance participants.
Along with the supply cap, Polkadot reduced annual token issuance from about 120 million DOT to 55 million DOT starting on March 14, 2026.
This update lowers inflation from nearly 10% to about 3.1%. The new design reduces the pace of token creation and aims to stabilize long-term supply growth.
More than 62% of DOT is currently staked for network security, which removes a large share of tokens from active trading.
The supply reduction event occurred on Pi Day, a reference to the mathematical value of pi. The number also appears in the formula used for the new issuance schedule.
Issuance Reductions Follow a Gradual Model
The new system does not follow the sudden block reward halving model used by Bitcoin. Instead, Polkadot uses a gradual reduction schedule.
Under the new model, the remaining supply scheduled to be minted will decrease by 13.14% every two years. The percentage refers to the first digits of Pi.

Because the reduction applies to the remaining issuance rather than total supply, the absolute number of new tokens will decline over time.
This approach creates a gradual slope instead of sharp supply cuts. As the reductions continue, inflation is expected to fall below 1% in the early 2030s.
The design aims to gradually slow token expansion as the ecosystem matures.
Dynamic Allocation Pool Replaces Treasury Burns
Polkadot also replaced its previous treasury burn mechanism with a system called the Dynamic Allocation Pool (DAP). The earlier model destroyed unused treasury tokens.
Under the new structure, surplus funds are collected and placed into a governance-controlled pool instead of being burned. The pool receives revenue from several network sources.
Funds entering the pool include newly minted DOT, validator slashes, transaction fees, and coretime sales revenue. Coretime represents the block space market within the Polkadot ecosystem.
Governance participants can distribute funds from the pool to several areas. These include validator rewards, nominator rewards, ecosystem development, and a strategic reserve.
The strategic reserve is a new funding category that allows the network to store funds for future ecosystem needs.

Staking Changes Affect Validators and Nominators
Polkadot will also implement updates to its staking system during 2026. The changes affect both validators and nominators.
Validators will be required to maintain 10,000 DOT in self-stake, and the funds must remain slashable under network rules. The network will also enforce a 10% minimum validator commission.
Validators who fail to meet the minimum stake requirement may face permissionless removal through a process known as chilling. Any network participant can trigger this action if requirements are not met.
Polkadot is also introducing a StakingOperator proxy structure, which allows operators to run validators on behalf of stakers without controlling their funds.
Changes for nominators are scheduled for Q2 2026. Under the new system, nominators will no longer face slashing penalties tied to validator actions.
The network will also shorten the unbonding period from 28 days to about 24–48 hours, allowing participants to access their staked tokens more quickly.
