Ethereum’s founder, Vitalik Buterin, unveiled an innovative proposal this week aimed at refining the platform’s staking mechanism.

As the world’s second-largest blockchain by market capitalization, Ethereum’s continued evolution is crucial for its vast user base, and these proposed changes aim to bolster decentralization, efficiency, and security.

A Decentralized Vision for Staking

The primary concern addressed in Buterin’s proposal revolves around the limitations of the current staking system.

Notably, he pinpoints decentralization issues surrounding the selection process for node operators across various staking pools and identifies inefficiencies in the current Layer 1 (L1) consensus mechanism.

Presently, the constraints of solo staking combined with issues surrounding liquid staking mean that the platform can only process between approximately 100,000 to 1 million BLS signatures per slot.

A further complication arises from the need for accountability in signing, which demands a participation record for each signature. If Ethereum scales up globally, using full danksharding for storage might still fall short, with a mere 16 MB per slot accommodating around 64 million stakers.

Drawing inspiration from models implemented by Rocketpool and Lido, Buterin suggests adopting a two-tiered staking system. In this structure, Node Operators and Delegators emerge as central figures.

To rectify this, Buterin suggests a two-tiered staking model:

  1. A high-complexity slashable tier with frequent activity but limited participants (around 10,000).
  2. A low-complexity tier, where members engage sporadically and face minimal or no slashing risk.

This model would involve the modification of the validator balance cap and implementing a balance threshold to categorize validators into these tiers.

Buterin elaborates on potential roles for small-stakers:

  • Random selection of 10,000 small-stakers for each slot who sign off on their slot’s head. If divergences arise between the staker and…
