Ethereum co-founder Vitalik Buterin has categorized the risks that certain staking use cases at the consensus layer may pose to the protocol.
In a blog post, titled “Don't overload Ethereum's consensus”(Don’t overload the Ethereum consensus layer), the co-founder of this blockchain explained the possible risks that certain use cases, implementations and additional applications of ether staking can represent for the stability of the network and for social consensus.
Ethereum is currently the second most capitalized cryptocurrency on the market and the leading blockchain par excellence for the development of smart contracts and innovative protocols.
In September, the network implemented the The Merge update as a hard fork, which led to the migration from the Proof of Work consensus protocol to the Proof of Stake consensus protocol. With this protocol change, Ethereum became an environmentally sustainable network based on validation nodes and ether staking.
Buterin stressed that Ethereum’s new consensus is “one of the most secure cryptoeconomic systems in existence,” with well-established protocol rules to penalize node misbehavior and a vast community of thousands of developers and millions of users watching carefully. However, despite the advantages offered by this consensus model, it is not without risks.
In his post, the Ethereum co-founder exemplified several use cases and implementations that can affect the stability of the blockchain, and even lead to its division.
Risks in the Ethereum consensus layer
As technology advances and its growing global adoption, developers have been discovering new use cases for blockchains that can meet different needs and demands. This applies to Ethereum's consensus layer, which Buterin said is serving other purposes.
However, the use of Ethereum validators and the network's social consensus for new purposes poses risks, both systemic and ethical, to the blockchain ecosystem.
Vitalik explained that, for example, the dual use of validator ether staked on the network, while it poses some risks, “is fundamentally fine.” However, developers or projects trying to recruit Ethereum’s social consensus through ether staking, for the purposes and ambitions of their own applications, is not.
In your post, Buterin listed several situations where validator reuse and social consensus “overload” can pose different risks. of low, medium and high impact for the blockchain. It also made recommendations to mitigate the risks of these situations.
With this, the blockchain co-founder seeks to raise awareness among the community of developers and users about the losses that some ambitious implementations can cause for the entire crypto ecosystem. Buterin also seeks to protect the stability of the blockchain and its participants.
At present, Ethereum's consensus layer secures over 18 million ethers in staking, the value of which amounts to over $34 million dollars.
