Polkadot locks a cap of 2.1 billion DOT, with inflation decreasing starting from 2026.

【Crypto World】A key proposal in the Polkadot ecosystem has finally been finalized. After WFC #1710 (Hard Pressure) was approved, this blockchain's economic model has a clear set of long-term rules—no more arbitrary adjustments.

The core of these rules is simple but hardcore: first, the total supply of DOT is permanently locked at 21 billion tokens; second, the issuance rate will automatically decrease every two years, with each reduction fixed at 13.14% of the remaining issuance. What is the biggest benefit of this design? No human interference, operating entirely based on an automatic mechanism.

Specifically, starting from March 14, 2026, Polkadot's annual issuance will officially enter a decreasing cycle. The first adjustment will occur then, reducing the annual inflation rate to around 3.11%. In other words, this blockchain finally has a tangible, measurable, and unchangeable growth expectation. For token holders and ecosystem participants, this predictability itself is valuable.
