Ethereum 'tax' debate erupts over proposal to redirect portion of staking rewards to ecosystem funding

The Ethereum community has been engaged in a heated debate over a potential mechanism that would redirect a portion of staking rewards toward ecosystem development — a move some have dubbed an Ethereum "tax."

In a post titled "Validator Redirected Revenue" published Sunday on the Ethereum Research forum, Kleros founder Clément Lesaege (clesaege) wrote that validators could collectively vote to redirect a small portion of their staking rewards — capped at 10% — to fund public goods. 

The post suggests that if a majority of validators support redirecting a share of staking rewards, the approved redirect rate would become mandatory for all validators.

"Ethereum is stuck in a coordination failure: everyone benefits from shared improvements but no single actor wants to pay when others can free-ride," the developer wrote. "This creates a persistent deadweight loss that weakens Ethereum's long-term competitiveness."

"Economies that reduce deadweight loss tend to outperform those that cannot," he wrote. "Successfully coordinating shared investment is essential to compete with both traditional economic systems that use coercive measures like taxation to reduce their deadweight loss and corporations that reinvest earnings back into future growth."

Lesaege said the goal of his post was not to reach consensus on a solution but to spark discussion around protocol-level underfunding. "We seek further feedback before working on a technical implementation to put forth as an Ethereum Improvement Proposal," Lesaege wrote.

Heated debate

The post quickly drew criticism from several prominent Ethereum contributors.

"Absolutely f**king not," said banteg, a pseudonymous developer, arguing that the mechanism could "bring politics into consensus layer" and make it more fragile.

Crypto attorney Gabriel Shapiro echoed that view and noted that any form of Layer 1 "devmine" or "tax" would require robust onchain governance. "[It] never works, never, because the people who are getting the money are also the ones designing the system," he wrote.

"Ethereum simply lacks those muscles and mechanisms, and suddenly having millions of dollars and existential investor optics at stake at a time when ETH investability is already majorly questioned, is not the time to build them," Shapiro added.

Cartel risks

A major concern over the proposal centers around cartel formation. Lesaege acknowledged in his post that if a majority of validators collude, they could "theoretically crank up the redirect rate and redirect those funds back to themselves."

However, Lesaege said under the proposed voting mechanism, cartel behavior would not be stable. "That is to say, if we assume that validators are purely driven by greed and seek to use this process to funnel more money to themselves, the 'king of the hill' option will never settle to a stable distribution that gives any validator more than they would get under the current status quo," he wrote.

Banteg warned that the most likely outcome would be someone deploying an autonomous cartel contract that redirects rewards to participating validators, effectively taking the 10% from those who opt out and boosting those who opt in. He added that no clear defense mechanism against this had emerged.
