Event description
CVV006 (“Enable Minimum Validator Fee Mechanism”) is a governance proposal on the Casper Network. It seeks to introduce a chain-level parameter that enforces a minimum commission fee that validators may charge to their delegators. Under current rules, validators may set their fee at 0%. The proposal is structured in two steps: first, update the codebase to enable enforcement of a minimum fee; second, a future governance vote will set the exact minimum percentage (e.g. 2%, 5%, etc.). The proposal entered the voting phase on 18 September 2025.
The Casper community has observed that many validators set 0% fee, leading to what the proposal describes as “unhealthy competition” that undermines validator sustainability.
Messari reports that CVV006 was formally live as a voting proposal on 18 September 2025, flagged for inclusion in Casper v2.2 release.
Community discussion has highlighted trade-offs: ensuring validator costs are covered vs. preserving competitive choice for delegators. Some community members express concern about new nodes joining under more restrictive fee floors.
If approved, the code enabling the minimum validator fee parameter will be merged into a future network upgrade (Casper v2.2) to provide the mechanism to enforce the fee.
A follow-up governance proposal will be submitted to set the value of the minimum fee (percentage) after the mechanism is ready.

Mixed-Positive — many in the Casper community seem supportive of the proposal’s goal to improve validator sustainability and avoid what some describe as a “race to the bottom” in validator fees. Others express concerns about how this might affect delegator choice and the ability of new validators to attract delegators under stricter minimum fee constraints.
Sample reactions:
“0% fee competition… leaves validators without revenue.”
“Validators will not be able to set their fee below this minimum.”
Changes to validator fee mechanics could impact delegator returns, validator behavior, and potentially staking dynamics. If the minimum fee is set too high, it may discourage delegation or hinder smaller validators; if too low, it may not resolve the sustainability issues.
Introducing a minimum validator fee is fairly uncommon in many PoS networks, which often rely on market forces among validators. This proposal reflects a shift toward more governance intervention to balance decentralization with validator sustainability.
The phased approach (first enabling mechanism, then setting value) helps reduce risk by allowing community feedback and empirical data before locking in parameters.
How this interacts with other economic proposals (like burning fees, inflation adjustments, or staking reward structures) will matter: validator income is one part of the economic model, and multiple levers are active.
