イーサリアムの共同創設者ヴィタリック・ブテリン氏は、イーサリアムバリデーターになるための主要な参入障壁である最低ステーキング要件を大幅に引き下げる計画を明らかにした。
Ethereum co-founder Vitalik Buterin has set his sights on a bold goal: drastically reducing the minimum staking requirement for solo validators on the Ethereum network. In a recent statement, Buterin highlighted the importance of increasing network participation and decentralization, particularly in the context of a rising demand for solo staking.
Currently, the minimum staking requirement to become an Ethereum validator stands at 32 ETH, a significant barrier for many aspiring to participate directly in securing the network. To address this challenge, Buterin proposed a two-pronged approach: reducing the minimum staking requirement to 1 ETH and lowering the bandwidth requirements for validators.
This move, according to Buterin, would open up the possibility for a larger number of individuals to participate in the validation process, ultimately enhancing the network's resilience and resistance to centralization.
To achieve these goals, two key innovations are mentioned by Buterin: PeerDAS (Peer Data Availability Sampling) and Orbit SSF (Single-Slot Finality). PeerDAS aims to improve data availability for blobs, which is crucial for Ethereum's scalability, while Orbit SSF establishes a solo-staker-friendly validator set management system.
The system, named Orbit due to its stable core and rotating periphery, ensures that validators, irrespective of their stake size, have an opportunity to validate the network and earn rewards. While PeerDAS is expected to be included in the second package of Ethereum's next major upgrade, Pectra, around 2025, there's no clear timeline yet for Orbit SSF.
Recognizing the potential delay in realizing the 1 ETH solo staking requirement goal, Buterin also proposed an intermediate solution: increasing bandwidth requirements and reducing the minimum staking requirement to 16 ETH or 24 ETH.
Buterin's recent statements on Ethereum staking and validation align with his strong advocacy for solo staking in recent times. At a Singapore-based Home Staking Summit in September 2024, he described solo stakers as "a layer of defense" against centralization risks like censorship and a 51% attack.
This is due to solo stakers' lack of organizational alignment, which makes it harder to coordinate such actions compared to, say, pooled staking service providers (PSPs) or centralized exchanges. As a result, solo stakers are less likely to participate in activities that could harm the network, like censoring transactions.
According to Dune Analytics data, pooled staking service providers currently dominate the Ethereum staking scene, with Lido leading the pack at 28% and Coinbase following at 11.5%. Notably, Lido's share has been declining in recent months.
