Setting minimum Validator commission to 10%
Dear community,
This proposal aims to set the minimum validator commission to 10%. This change aligns with the Polkadot 2.0 roadmap. It's a necessary response to the economic shift we've seen since March 14th “Polkadot Halving” (Referendum #1710), and the upcoming 10,000 DOT validator self-bond requirement.
Motivation: As outlined in the official roadmap and recent WFC Referendum #1827 and the community discussion in Polkadot Forum, Polkadot is undergoing a fundamental transition toward the Dynamic Allocation Pool (DAP) model.
On January 28, 2026, the community ratified Phase 1 of the DAP in the previously mentioned WFC Referendum #1827, which introduced a more agile issuance model and redirected treasury burns and slashes into the DAP account. However, a critical piece of this transition remains pending.
While the network issuance was significantly reduced on March 14, 2026, the corresponding protective measures for validators, specifically the 10% minimum commission, were originally bundled with the 10,000 DOT self-stake requirement scheduled for late April.
The case for immediate implementation: There is a growing consensus within the Polkadot community and validator groups that the 10% commission floor should have ideally coincided with the issuance reduction. Waiting until the end of April creates an unnecessary sustainability gap for node operators.
Besides that, the long-term DAP vision (Phase 2) will eventually provide validators with fixed income for operational costs and vested DOT rewards. Until that phase is fully live, the 10% commission floor is the primary mechanism to ensure validators remain viable following the 53.6% reduction in total issuance.
This proposal seeks to remedy the timing mismatch by enacting the 10% floor now, rather than waiting for the broader April referendum.
Post-enactment enforcement: We want to make this transition as smooth as possible, so once the proposal passes, we’ll trigger a one-time batch update (staking.forceApplyMinCommission) to automatically bring anyone currently below 10% up to the new minimum. This keeps the playing field fair for everyone from day one and saves node operators the trouble of having to update their settings manually.

Thanks for taking the lead on this and getting it on-chain. You have my supporting.
I also have further comments on the DAP v2 structure and allocative efficiency of resources to support 600 active validators. I plan to share that here -> https://github.com/paritytech/polkadot-sdk/issues/11032#issuecomment-3876860478 soon TM.
Policy choice disguised as economic necessity. if validators truly couldn't survive, they'd raise commission naturally. You don't need governance to enforce it.
