According to Cointelegraph, at least five Ethereum liquid staking providers, including Rocket Pool, StakeWise, Stader Labs, Diva Staking, and Puffer Finance, have either committed or are in the process of committing to a self-limit rule. This rule states that they will not own more than 22% of the Ethereum staking market, in an effort to ensure the Ethereum network remains decentralized. Ethereum core developer Superphiz proposed the self-limit rule to address concerns of Ethereum staking becoming increasingly centralized. The 22% limit was chosen because 66% of validators need to agree on the state of Ethereum, meaning at least four major entities must collude for the chain to reach finalization. Finality is the point where transactions on a blockchain are considered immutable, ensuring that transactions within a block cannot be altered. Notably, the largest Ethereum liquid staking provider, Lido Finance, voted by a 99.81% majority not to self-limit in June. Lido currently dominates the Ethereum staking market, accounting for 32.4% of all staked Ether, while the next entity, Coinbase, accounts for only 8.7% of the market, according to data from Dune Analytics. The self-limit proposal has received mixed reactions from the Ethereum community, with some arguing it has nothing to do with 'Ethereum alignment' and others expressing concern over potential centralization issues.
