Headline: Ethereum dev warns validator-funded grants could hand power to a staking “cartel”
Lefteris Karapetsas — founder of Rotki and an Ethereum developer — has pushed back hard on a new funding idea that would let validators redirect a slice of staking rewards to support public goods, infrastructure and core protocol work.
What the proposal would do
- Called Validator Redirected Revenue, the plan would let validators choose to send 0%–10% of their staking rewards to a set of projects.
- If a majority (more than half) of validators opt for a non-zero rate, that contribution would be applied across the entire validator set.
- Validators would nominate recipient addresses and a “splitter” contract would route the collected funds to selected projects.
- Proponents estimate a 5%–10% redirect could raise on the order of 50,000–70,000 ETH per year for ecosystem funding.
Why Karapetsas objects
- After reading the proposal and the reactions to it, Karapetsas warned the mechanism risks creating “a cartel of the top stakers.” If large staking operators coordinate, they could effectively divert up to 10% of the network’s validator rewards and impose funding choices on the wider validator base.
- Because the contribution would apply network-wide once a majority of validators agreed, smaller or dissenting validators could be forced to fund decisions they dislike.
- He also tied his opposition to broader concerns about Ethereum core development: he believes core teams have drifted away from the needs of protocol users and developers, that the ecosystem has accumulated unnecessary technical complexity (citing RLP, SSZ and RLPx), and that funding changes could accelerate consolidation of research and development — cementing an existing development culture he does not want to keep rewarding.
Supporters’ case and governance worries
- Backers frame the proposal as an answer to Ethereum’s free‑rider problem: many projects benefit from shared security, tools and public infrastructure while only a few groups pay directly. Validators, who stand to benefit from Ethereum’s long-term value, are presented as natural funders.
- The proposal itself acknowledges tricky incentives: staking operators might set distribution preferences while ETH holders — who actually bear the yield reduction — have limited say.
- Karapetsas also questioned ideas like a pre-approved funding list, asking who would decide which projects make that cut.
An alternative and the road ahead
- Karapetsas said he’d prefer funding via burned ETH fees rather than siphoning validator rewards, while acknowledging that fee-burn approaches have their own problems tied to gas usage patterns.
- Importantly, Validator Redirected Revenue is still a research forum proposal, not a protocol change. The next steps hinge on researchers resolving governance and incentive questions without eroding staker confidence.
Bottom line
Karapetsas’s critique adds a clear warning to the debate: funding Ethereum’s public goods is an urgent problem, but any reform must avoid concentrating control over collective rewards in the hands of the largest stakers. The community now faces the challenge of finding a mechanism that supports public infrastructure without creating outsized influence for a few operators.
