Ethereum Founder Vitalik Buterin Cautions Against Overloading Consensus

In a recent blog post, Vitalik Buterin warned against overloading the network’s consensus. While Ethereum’s consensus is highly secure, Buterin said overloading it would expose the ecosystem to high systemic risks.

Buterin’s post follows massive congestion on the Bitcoin network, which led to a surge in transaction fees.

Possible Risks of Consensus Overload

Crypto assets like Bitcoin and Ethereum use the consensus mechanism to validate transaction authenticity and maintain the security of the underlying blockchain.

This consensus mechanism influences how a blockchain network verifies transactions while determining network fees, transaction speed, and more.

Amid surging transaction fees on the Bitcoin network due to congestion, Buterin asked users not to overload Ethereum validators to preserve the consensus mechanism.

In his blog post, the co-founder warned against the dangers of overworking Ethereum’s consensus. He said some proposals suggested using Ethereum consensus for other purposes, such as price oracles and re-staking. And some even suggested using layer-1 forks to recover layer-2 projects in the event of unexpected occurrences.

While the urge to expand the blockchain’s core functionality is high, Buterin said such an extension would render it fragile. He pointed out that a certain subset of these techniques brings high systemic risks to the ecosystem and should be resisted and discouraged.

If validators get overloaded, the ecosystem could face such risks as bugs or 51% intentional attacks initiated by actors who advocate for a fork to protect their deposits. These risks include creating ETH/USD price oracles where ETH holders or validators could receive bribes to vote.

According to Buterin, a case scenario where participants receive money to offer the wrong answer would cause honest people to lose money. In that case, Ethereum can only fork to recover users’ funds, which is a high risk.

However, while Buterin disagrees with price oracles, he acknowledged the need for better Oracles amid high bug risks. Buterin believes various problems are inherently different and should have unique approaches. 

Buterin Advices Against Extending Ethereum Consensus Functionality

Overall, Buterin’s article kicks against the expansion of Ethereum consensus functionality as that would cause increased costs, complexities, and risks in running a validator.

In addition, he advises the community to be cautious of application-layer projects that may increase the scope of blockchain consensus outside core Ethereum protocol rules.

He urged the Ethereum community to preserve the blockchain’s minimalism and support re-staking without slippery slopes that could extend the roles of Ethereum consensus. The founder asked users to help developers find alternative strategies to achieve their security goals.

After transitioning from proof-of-work to proof-of-stake consensus last year, Ethereum recently witnessed the Shapella upgrade on April 12. 

The upgrade commissioned a phased release of staked Ether, increasing activities and transactions on the network. That explains the increased concern for security and validator risks on the network.
