Vitalik Buterin, the co-founder of Ethereum, has expressed concerns about decentralized autonomous organizations (DAOs) gaining a monopoly over the selection of node operators in liquidity staking pools. In a blog post on September 30, Buterin warns that as staking pools adopt the DAO approach for governance over node operators, it can expose them to potential risks from malicious actors.
Buterin emphasizes that if a single staking token dominates in a DAO approach, it could lead to a single governance gadget controlling a significant portion of all Ethereum validators, making it vulnerable to attacks. He cites the example of Lido, a liquid staking provider that uses a DAO to validate node operators. He acknowledges that Lido has implemented safeguards against this type of attack, but he cautions that relying on just one layer of defense may not be enough.
Looking at Rocket Pool, Buterin explains that the platform offers the opportunity for anyone to become a node operator by depositing 8 Ether (ETH), which at the time of writing is valued at approximately $13,406. However, he notes that this also comes with risks, stating that the Rocket Pool approach allows attackers to carry out a 51% attack on the network and force users to bear most of the costs.
Buterin acknowledges the necessity of having a mechanism to determine who can act as underlying node operators, as an unrestricted approach would enable attackers to join and amplify their attacks using users’ funds. To address this issue, he suggests encouraging ecosystem participants to utilize a variety of liquid staking providers. This would decrease the likelihood of any provider becoming excessively large and posing a systemic risk.
However, Buterin cautions that relying solely on moralistic pressure to solve problems is not a stable long-term solution. While using multiple providers may mitigate risks, he believes that a more robust and sustainable approach is needed. The increased adoption and integration of various security measures and technological advancements could help protect staking pools and prevent them from being compromised by malicious actors.
In conclusion, Buterin raises valid concerns about the potential risks associated with DAOs having a monopoly over node operators in liquidity staking pools. He highlights the need for multiple layers of defense, emphasizing the importance of utilizing a variety of liquidity staking providers to mitigate the risks of attacks and systemic failures. However, he also acknowledges the long-term instability of relying solely on moralistic pressure, urging for the development of more robust solutions to ensure the security and sustainability of staking pools.
