A group of Ethereum staking service providers have agreed to a self-imposed limit which would restrict the amount of the staking market they control.

Superphiz, a member of the Ethereum staking community, said in an Aug. 31 post on X that RocketPool, Stakewise, Stader Labs and Diva Staking were all in the process of committing to an agreed-upon limit to not own more than 22% of all Ethereum validators.

The limit was determined because finalization requires 66% of validators to agree on the chain, meaning that at least four entities would need to collude to finalize a rogue chain under the proposed 22% self-limit, he explained. Finalization refers to the state of the blockchain which guarantees transactions within a block cannot be altered.

“This is a low bar, but a good start,” Superphiz said, adding that the first step was to make sure a staking service did not gain control of 33% of validators.

In the event that it happens, he noted that they would essentially have the power to prevent finalization if they chose, and even resist a forced slash by the network.

Some users pointed out that verbal commitments such as this one were easy to make when the likelihood of one staking service provider reaching 22% of market share was fairly low.

Others highlighted that Lido already controls 32.4% of the staking market, with the amount of ETH staked through the platform amounting to over 22% of the cryptocurrency’s supply. Interestingly, 99.8% of the Lido community voted against imposing a self-limit on its share of the staking market in June.
