In a recent blog post dated May 21, Vitalik Buterin cautioned about the potential hazards of burdening the Ethereum consensus with excessive demands. The Ethereum co-founder has emphasized the importance of upholding the principle of consensus minimalism and averting the tendency to overload validators with extraneous tasks.
Buterin expressed particular apprehension about the concept of re-staking, an attribute that expands the role of Ethereum validators to include securing other blockchains. This over-extension, he suggests, could lead to an unnecessary complexity in the Ethereum consensus protocol, straying from its foundational design.
Buterin expressed unease regarding projects that might inadvertently infuse the ecosystem with unnecessary risks and overextend the responsibilities of Ethereum validators. He highlighted his concerns about “re-staking,” a mechanism being advanced by entities like Eigen Layer, which expands the role of Ethereum validators to secure external chains. Buterin voiced worry that such a move could jeopardize network security.
Ethereum is one of the most secure systems according to Vitalik
Through his post, aptly titled “Don’t Overload Ethereum’s Consensus,” Buterin communicates a clear warning. He underscores that leveraging Ethereum’s network consensus for other objectives may invite significant systemic risks that could pose a threat to the entire ecosystem. Such activities, Buterin firmly states, should be actively dissuaded and countered.
”The purpose of this post will be to explain in detail the argument why, in my view, a certain subset of these techniques brings high systemic risks to the ecosystem and should be discouraged and resisted.”Vitalik Buterin.
Vitalik Buterin points out that the Ethereum network’s consensus is among the most secure cryptoeconomic systems in existence. With approximately 18 million ETH, equivalent to roughly $34 billion, validators finalize a block every 6.4 minutes. This is made possible by executing numerous protocol implementations, which adds redundancy.
Buterin further illustrates that if the cryptoeconomic consensus were to fail due to a bug or an intentional 51% attack, there is a large community composed of thousands of developers and an even larger user base vigilantly monitoring to ensure the correct recovery of the chain. He highlights that the protocol’s rules are designed to ensure that in the event of a chain recovery, attackers are likely to face severe penalties.
Potential problems of re-staking
Buterin remarked that while re-staking can serve low-risk objectives, there are instances where it could imperil the security of the mainnet. Such situations could arise, for example, when Ethereum validators are subjected to slashing on third-party chains. Slashing is a disciplinary action taken against validators who partake in objectionable activities such as improperly managing their stake or incorrectly handling transactions.
Instead of extending the role of Ethereum consensus, Buterin advocates for the preservation of the chain’s minimalism and backing for re-staking applications that do not appear to lead to risky enlargements of its responsibilities.
